Solar Panel Cost
The cost of solar panels has declined dramatically over the last several decades and, with a sharp rise in utility electricity rates in 2022, home solar now offers more cost savings potential than ever before.
In fact, the 2023 Heatmap Climate Poll found that 46% of US adults want to power their homes with solar panels in the future while 13% already do.
So, what’s standing in the way of American homeowners and solar panels? The biggest hurdle is often the cost of solar panels. And like a monster in a horror movie, the cost of solar panels is far less intimidating once you shine some light on it and understand how it works.
In this article, we’ll explore:
As always, our goal is to give you the resources and knowledge to make educated decisions during the solar process.
Is the price of solar panels falling?
The price of solar panels has declined substantially over the last decade as the industry has matured and reached production at the largest global scale.
Since 2010, solar panel have fallen by roughly 90% while global solar deployment has grown by over 400%, and this incredible growth rate along the entire global solar supply chain has dramatically reduced prices.
Just like computers, big-screen TVs, and cell phones, the economies of scale that solar panels now enjoy have produced a dramatic cost curve that has fundamentally changed the energy industry.
Utility-scale solar installations are now cheaper than all other forms of power generation in many parts of the world and will continue to replace older, dirtier power plants run on coal and natural gas.
Additionally, homeowners are now able to own their power production more cost-effectively than ever before.
Price per Watt vs cost per kWh
There are two main ways to calculate the cost of a solar system:
- Price per watt (/W) is useful for comparing multiple solar offers
- Cost per kilowatt-hour (cents/kWh) is useful for comparing the cost of solar versus grid energy
Let’s dive a little further into each measurement.
What is solar price per watt?
A fully installed solar system typically costs 3 to 5 per watt before incentives like the 30% tax credit are applied. Using this measurement, 5,000 Watt solar system (5 kW) would have a gross cost between 15,00 and 25,000.
Price per watt for larger and relatively straightforward projects are often within the 3-4 range. Claiming incentives like tax credits and rebates can bring the PPW even lower.
However, the following factors may push your solar price per watt into the 4 to 5 range.
- Smaller system size
- Unusual roof material or layout
- Premium panel and inverter models
- Multiple arrays versus a single array
- Additonal work like panel box upgrades, trenching, or roof repair
How to calculate solar price per watt
Calculating the price per watt for a solar system is very straightforward — it’s simply the system cost divided by the number of watts in the system.
Price per watt (/W) allows for an apples-to-apples comparison of different solar quotes that may vary in total wattage, solar panel brands, etc.
Pro tip: It can helpful to know your solar price per watt before and after claiming the 30% tax credit.
Ultimately there are many factors that figure into the price per watt of a solar system, but the average cost is typically as low as 2.75 per watt. This price will vary if a project requires special adders like ground-mounting, a main panel upgrade, EV charger, etc.
| Solar Price Per Watt | Solar Price Per Kilowatt-Hour |
| GROSS system cost / Total system wattage | NET system cost / Total lifetime system production |
| Useful for comparing solar quotes against one another | Useful for comparing solar versus utility bill |
| Pertains to the POWER of a system | Pertains to the PRODUCTION of a system |
| Typically 3.00-4.00/watt | Typically 0.06-0.08/kWh |
Cost Per Kilowatt-Hour (kWh)
Another measure of the relative cost of solar energy is its price per kilowatt-hour (kWh). Whereas the price per watt considers the solar system’s size, the price per kWh shows the price of the solar system per unit of energy it produces over a given period of time.
Net cost of the system / lifetime output = cost per kilowatt hour
You may also see this referred to as levelized cost of energy (LCOE).
What is a kWh?
A kilowatt-hour is a unit of energy and is equivalent to consuming 1,000 watts – or 1 kilowatt – of power over one hour. For reference, an energy efficient clothes dryer uses around 2 kWh of electricity per load, while central air conditioning uses around 3 kWh per hour.
While price per watt is most helpful comparing the relative costs of solar bids, solar energy cost per kWh is best used to illustrate the value of solar relative compared to buying your power from the electric utility.
For example, the average cost of a solar system purchased through solar.com is 6-8 cents per kWh, depending on the size of the system, type of equipment and local incentives.
Let’s compare that to grid electricity in major metro areas for April 2023 to the average cost per kWh of home solar energy:
| Grid electricity (cents/kWh) | Solar.com electricity (cents/kWh) | |
| New York City | 21.6 | 6-8 |
| Chicago | 18.0 | 6-8 |
| Miami | 16.8 | 6-8 |
| Houston | 15.2 | 6-8 |
| Denver | 15.2 | 6-8 |
| Los Angeles | 26.9 | 6-8 |
| Seattle | 12.7 | 6-8 |
Based on this prices, it costs around 43 cents to dry a load of laundry using grid electricity in New York and only 14 cents to dry a load using solar power.
How do I calculate the cost of solar panels?
There are a few ways to get a rough estimate for how much solar panels will cost without sitting through a sales pitch. These include:
- Online calculators
- Hand calculations based on your electricity usage
- The average cost of solar panels for comparable homes
Let’s start with the quickest method: online calculators.
Using a solar panel cost calculator
First, you can use an online solar cost calculator, like this one powered by solar.com. Simply punch in your address and your average monthly electricity bill, and the calculator will give you a side-by-side comparison of the cost of solar versus paying for utility electricity.
But before you use any solar panel cost calculator, it’s important to understand that there are dozens of variables that affect the cost of solar panels, and solar calculators work by making assumptions about those variables.
For example, your solar savings depends largely on how much utility rates increase over 25 years. Most calculators assume 3-5% annual inflation based on historical averages – but nobody can know for sure where will go over the next 25 years.
Solar savings is also geographically sensitive, since every state has different incentives, electricity rates, sun exposure, and net metering policies.
For example, a solar panel cost calculator for California would have drastically different assumptions than a cost calculator for New York.
How to calculate the cost of solar panels by hand
If you’d rather make your calculations offline, there are a few simple steps to estimate the cost of your solar system based on your electricity usage.
- Dig up some recent electricity bills (the more the better!)
- Average them together to get a baseline for your monthly electricity consumption
- Divide your monthly consumption by 30 to get your daily electricity consumption.
Once you have your average daily electricity use, follow the steps in the graphic below. Here are a few tips:
- You’ll have to assume the price per Watt (PPW) you can get from a local solar installer. This typically ranges between 3.50 and 5 before incentives
- Pro tip: Run the high and low PPW scenarios to get a range of solar costs
If hand calculations aren’t your thing, you can get a quick-and-dirty estimate based on the cost of solar for comparable homes.
How much do solar panels cost per square foot?
The third – and least accurate – way to get an idea of how much solar panels will cost for your home is to see how much solar panels cost for homes similar to yours.
Now, we absolutely encourage you to talk to friends, family, and neighbors that have installed solar systems to get a sense of the pros, cons, and cost. However, we’ve done a lot of that legwork for you.
We analyzed thousands of systems sold on solar.com in 2022 to find the average cost of solar panels for homes based on their square footage of living space and number of bedrooms.
On average, solar panels cost 8.77 per square foot of living space, after factoring in the 30% tax credit. However, the cost per square foot varies based on the size of the home.
For example, the post-tax credit cost of solar panels for a 2,500 square foot home is around 20,000 for a rate of 7.96 per square foot.
But how much do solar panels cost for a 1,500 square foot home? The average system cost only drops by 1,000 and the cost per square foot increases to 12.83.
| Square footage of living space | Solar cost per square foot (after tax credit) |
| 1,500 | 12.83 |
| 2,000 | 10.23 |
| 2,500 | 7.96 |
| 3,000 | 7.02 |
| 3,500 | 5.79 |
| Average | 8.77 |
Based on systems purchased on solar.com in 2022. Square footage per Zillow.
If you don’t know your home’s square footage, you can either look it up on Zillow or get a rough estimate using the number of bedrooms.
What’s the cost of solar panels for a 3-bedroom house?
The average pre-incentive cost of home solar is 29,161 for a three-bedroom house, or 20,412 after applying the 30% tax credit.
However, as shown in the chart below, the number of bedrooms isn’t a great indicator of the size and cost of a solar system – and neither is living space, for that matter.
Solar systems are typically sized based on electricity consumption – not square footage or number of bedrooms. That’s because a two-bedroom house with two EVs and an electric heat pump would likely use more electricity than a four-bedroom house with no EVs and gas heating.
So, you can use this method to get in the right ballpark, but keep in mind that the previous two methods are more accurate.
Once you have a rough cost estimate for your solar system, it’s time to compare it to the cost of buying electricity from a utility provider to get a sense of how much you can save by going solar.
Do you really save money with solar panels?
Yes, homeowners across the US can save money on energy costs by powering their home with solar panels instead of purchasing electricity from a utility. This is especially true following the Rapid rise in grid electricity rates in 2022.
Home solar is essentially a way to buy electricity in bulk – similar to buying a giant can of coffee grounds from Costco instead of 50 individual cups at Starbucks. The 25 can of grounds costs more upfront but pays for itself after just 9 Grande Lattes at 3 each and nets 125 in savings over its lifespan.
It’s the same concept with home solar, just on a much larger scale.
How much money do you save a month with solar panels?
Exactly how much money you save a month with solar panels depends on a few main ingredients:
- Utility electricity rates
- Electricity consumption
- How you finance your system
- Your energy goals
These factors vary from household to household, so let’s take a look at the average monthly electric bill with solar panels and without solar panels.
- By paying cash for a solar system, you can enjoy maximum lifetime savings – often north of 50,000 – but it can take several years to reach a payback period
- By taking out a solar loan, you can front-load your cost savings by making solar loan payments that are less than your average electricity bill, but interest payments eat into your lifetime savings
Adjusting the size of your solar system and how you finance it gives you control over your essential electricity costs – something you’ll never have by purchasing electricity solely through a utility company.
How long does it take for solar panels to pay for themselves?
The payback period for solar panels is typically 6-11 years, depending on factors like your utility rate, electricity consumption, and how you financed the system.
With a solar loan, many homeowners are able to achieve “Day 1” savings by having a loan payment that’s lower than their average electricity bill. However, interest payments on the loan eat into the long-term energy cost savings.
By paying cash for solar, homeowners maximize their lifetime savings potential, but typically need to wait 6-11 years to recoup the upfront investment.
Is solar worth it financially?
As a hedge against energy inflation, home solar is considered a safe and steady investment with a rate of return similar to real estate and 401k. Remember, home solar allows you to replace your electricity costs with lower, more predictable monthly payments on your solar system.
Why is it financially beneficial to pay for solar rather than utility electricity?
The chart below shows the steady rise of utility electricity from 5 cents per kWh to 16.5 cents per kWh over the last 44 years.
For non-solar owners, this trend is a nightmare because it shows that utility rate hikes are about as certain as death and taxes. But if you have a home solar system, utility rate hikes are the fuel for your energy costs savings over the 25-year warrantied life of your solar system.
Home solar also acts as a time machine, of sorts. Instead of paying the current utility rate for electricity, the cost per kilowatt-hour of home solar is typically around 6-8 cents – roughly what utilities were charging 40 years ago.
So, are solar panels worth your money?
Solar panels are worth your money if you want to want to:
- Take control over your essential electricity costs
- Hedge against energy inflation
- Reduce your carbon emissions
- Increase your home value
- Provide backup power for grid outages (when paired with battery)
However, if you have a hunch that grid electricity are suddenly going to plummet below 8 cents per kWh and stay there for 25 years, then don’t buy solar panels.
How much does solar panel installation cost?
Installation labor accounts for around 5.5% of the total cost of a residential solar project, according to a 2022 report from the National Renewable Energy Laboratory.
That amounts to 1,375 for a 25,000 solar project.
This figure often seems surprisingly low to homeowners that are used to labor being a bigger chunk of the cost for car repairs, landscaping work, and other home upgrades.
It’s worth noting that installation costs vary from project to project based on the local minimum wage and scope of the project. For example, labor for specialized electrical work typically costs more than general labor for panel installation. This variability is why it’s tough to find a solar installation cost estimator online.
Overall, labor costs have fallen in the last decade as technology has improved and the labor force has matured. The chart below shows the solar panel installation cost breakdown since 2010.
- The overall cost of residential solar fell by 64% in the 2010’s
- Solar module, inverter, and labor costs have come down substantially in the last decade
- Non-labor soft costs and electrical hardware have been more stubborn
At the end of the day, the installation labor makes up a very small chunk of the total cost of a solar system – and it’s well worth having professionals install a system that you want to last for 25 years or more.
Can I install solar panels myself?
Some homeowners with advanced knowledge and experience in construction, circuitry, and local permitting guidelines (not to mention a good amount of time on their hands) are able to successful install solar panels up to inspection and interconnection standards.
However, it’s important to consider that DIY solar installation may void the manufacturer warranties on the equipment and does come with workmanship warranties.
So, if there are problems with the equipment or the installation, like a panel broken during installation or a leaky hole in the roof, you are on your own to solve and pay for them.
It’s also worth noting that full-service installers typically handle permitting, interconnection, and applying for incentives — which can be complicated and time consuming.
How much does one solar panel cost?
The average cost for one 400W solar panel is between 250 and 360 when it’s installed as part of a rooftop solar array. This boils down to 0.625 to 0.72 per Watt for panels purchased through a full-service solar company.
At a retail vendor, such as Home Depot, you can buy a single 100W solar panel for 100 or a pack of 10 320W solar panels for 2,659, which boils down to 0.83 to 1 per Watt.
Given the relationships with panel manufacturers, full-service solar companies are able to offer a much lower cost per solar panel than retail establishments.
How long do solar panels last?
Today’s solar panels typically have 25-30 year performance warranties that guarantee a certain level of production (usually 85-92% of its Day 1 capacity) during that time. However, the panels themselves can last and generate a meaningful amount of electricity for much longer.
For example, the first modern solar cells were created in 1954 and are still producing power from their display case in a museum. Similarly, a solar panel installed in 1980 on a rooftop in Vermont is still producing at 92% of its original capacity.
Based on manufacturer warranties, it’s safe to assume today’s solar panels will produce at a high level for at least 25-30 years. The real question is how far will they overshoot that warrantied lifespan.
How can I lower the cost of solar panels?
Although home solar is already more affordable than paying for utility electricity, there are a few ways to reduce the cost of your system and maximize your energy cost savings.
Solar incentives
First, there are solar incentives offered by federal, state, and local governments, in addition to utility providers.
The most notable is the federal solar tax credit worth 30% of what you pay for solar panels. So, if your all-in cost is 25,000, you can claim a tax credit worth 7,500 on your federal income tax return for the year your system was deemed operational.
Next, many states have additional incentives like tax credits, tax exemptions, and rebates for residential solar systems. For example, New York has all three with its NYSERDA rebate, 25% state tax credit, and sales and property tax exemptions for solar installations.
At the local level, many city governments, municipal utilities, and investor-owned utilities have incentives for solar panels, battery storage, and other energy efficiency home upgrades.
- The Austin Energy solar rebate worth 2,500
- California’s Self-Generation Incentive Program with battery rebates up to 1,000 per kWh of capacity
- Massachusetts’ handful of municipal utility rebates
It’s well worth spending 5-10 minutes searching for solar incentives through your state, county, city, and utility provider.
Compare multiple quotes
The next way to reduce the cost of solar panels is to shop for the lowest price like you would for cars or a new pair of hiking boots.
In most areas of the US, there are at least a handful of solar installers willing to compete for your business. Getting quotes from at least three reputable installers gives you a sense of a fair price, weeds out scammers, and gives you leverage to negotiate for a lower price.
Admittedly, it takes time and effort to research installers, set appointments, and sit through sales pitches in order to gather quotes. Solar.com simplifies this process by instantly generating dozens of quotes from our network of trusted installers so you can easily compare quotes in a pressure-free environment.
However you choose to do it, comparing multiple quotes is crucial to lowering your solar cost and setting yourself up for a long-lasting and productive solar installation.
Can I get free solar panels?
Despite what the ads on and YouTube say, it is not possible to get free solar panels from Tesla, Home Depot, or the US government. This is a common scam used to gather personal data and/or trick people into signing long-term solar lease agreements that are far less favorable than owning solar panels.
For example, in February 2023, a page called “Solar Panel Rate” ran multiple ads claiming Elon Musk was paying homeowners 2,500 to test out new solar technology. Further inspection revealed that the account was run by three individuals in Indonesia and the ads were designed to collect personal information.
There are also dozens of YouTube ads claiming that the “US government is giving away free solar panels.” While it’s true that the federal government strengthened the solar tax credit and created new home electrification incentives by passing the Inflation Reduction Act, it is not “giving away” solar panels.
Recap
The falling cost of solar panels coupled with the recent spike in grid electricity have made home solar a reliable means of reducing your essential energy costs.
While the five-figure price tag for home solar often gives people sticker shock, it’s important to remember that going solar is like buying 25-years worth of electricity in bulk. It may cost more upfront, but it is much more affordable than buying electricity at the retail rate from a utility.
Plus, there are zero-down solar loans that can spread out the cost of solar panels and, in many cases, provide instant energy cost savings.
Installation accounts for roughly 5.5% of the total cost of solar projects. However, non-labor soft costs like permitting, inspection, interconnection, and general overhead makeup around half of the cost of home solar.
There are a few ways to reduce the cost of going solar. First, research federal, state, and local solar incentives to make sure you’re not leaving money on the table. Second, shop around for the best price by getting multiple quotes from vetted local installers. (Solar.com makes this quick, easy, and pressure-free).
Finally, neither Elon Musk nor the US government are giving away free solar panels. And if they were, they wouldn’t be advertising it on and YouTube.
Steer clear of free solar ads to avoid giving away personal information or ending up in a long-term solar lease.
Frequently asked questions
Is one solar panel enough to power a house?
One solar panel is not enough to power a house. Home solar systems typically feature 10-20 panels in order to produce enough power to offset 100% of the average household electricity consumption.
It’s also worth mentioning that installing one solar panel at a time isn’t very efficient, as there are soft costs associated with designing, permitting, inspecting, and interconnecting solar systems. Homeowners typically get the most bang-for-their-buck by installing at once as many solar panels as they’ll need to offset current and near-future electricity needs.
How long can a house run on solar power alone?
According to the NREL, a small solar system with 10 kWh of battery storage can power the essential electrical systems of a home for three days in parts of the US and in most months of the year.
Essential electrical systems do not include electric heating or air conditioning, which require massive amounts of electricity.
However, it’s worth noting that solar systems need to be paired with battery storage in order to provide backup power during outages. Solar-only systems are automatically shut off during outages as a safety precaution to protect the technicians repairing the grid.
What is the main downside of solar energy?
The main downside of solar energy is that it’s intermittent. In other words, solar panels need sunlight to produce electricity, and when the sun goes down production stops.
This intermittence poses challenges to grid operators because it creates an influx of energy during the middle of the day, when consumption is down, and a lack of energy in the evening, when consumption is peaking.
The most obvious solution to this challenge is various forms of energy storage including batteries, pumped hydro, compressed air, and thermal technologies.
In fact, residential solar and battery systems in California provided around 340 MW of power during a heatwave in September 2022 to help prevent power outages.
Is it worth it to get solar panels in California?
Given its abundant sunshine and high utility electricity rates, California is one of the best states to save money with home solar.
In fact, even after reducing the value of solar exports through NEM 3.0 solar billing, Californian’s can still save more money with solar than homeowners in most other states. Under NEM 3.0, it’s much more beneficial to pair solar systems with battery storage in order to use as much of your own solar production as possible instead of exporting it onto the grid.
Many installers are offering less expensive “arbitrage” battery systems that allow solar owners to store and use their own electricity, but don’t provide backup power during outages (hence the price decrease).

A single solar panel costs between 2.67 and 3.43 to buy and install. 4 The price of the whole system is based on its capacity, measured in watts. How big a system you need will be based on how much energy you use, your roof’s sunlight exposure and panel efficiency.
The amount you save will rely on several factors, including: 18
- Region’s sunlight exposure
- Cost of solar system (including battery, where available)
- Cost of electricity
- Energy use
- Local rebates and incentives
The average payback period for a residential solar system is between six to nine years, depending on the cost of your system, incentives and savings from your energy bill. 19
Here’s a closer look at some of the things that determine your system costs.
Here’s a breakdown of installation costs, based on findings from the National Renewable Energy Laboratory: 10
| Labor | 0.30 per watt |
| Panels | 0.47/Wdc |
| Inverter | 0.12/Wdc. 0.39/Wdc |
| Permit/Inspection | 0.06/Wdc |
| Structural BOS | 0.10/Wdc |
| Electrical BOS | 0.19–0.27/Wdc (Varies by inverter option) |
| Sales tax | Sales tax varies by location; weighted national average: 6.9% |
| Electrician | 19.74–38.96 per hour (Varies by location and inverter option) |
| Laborer | 12.88–25.57 per hour (Varies by location and inverter option) |
| Burden rates | (% of direct labor) Total nationwide average: 31.8% |
Figures based on the average 6.2 kilowatt residential solar system.
These figures are based on the average 6.2 kilowatt solar system. The cost of each system will vary based on panel manufacturer, inverter option, location and equipment.
Maintenance of solar panels ranges from routine cleaning to major repairs. On average, households pay 150 for one solar panel cleaning. 11 Companies charge between 3 to 10 per panel based on roof slant, home height and system size. 11 Some firms charge a flat rate fee for a system cleaning. If you clean your system twice a year, as recommended, you can expect an annual bill of about 300.
If your system is damaged, you may incur additional expenses. Repairs to your system will include the of equipment and labor. Labor is typically priced at 100 per hour. Materials for solar repairs could be as little as 180 but may also be greater than 1,000. Your combined, total bill may range from 200 to 3,000. 11
The four most common types of damage to a home solar system and the costs of repairs area: 11
| Broken glass panel | 20 – 350, plus labor |
| Cracked panel | 100 – 400 |
| Loose connection | 100 |
| Replacement inverter | 100 – 2,500 |
Like cleaning costs, the amount you pay for repairs is affected by things like roof steepness, system type and system size. And if your panels have extensive damage, it may be cheaper to replace them. 11
When you own your system, you are responsible for the cost of maintenance and repairs. Your warranty should cover specific system failures; contact your installer before you begin repairs. A Sunrun solar lease, lets you save thousands of dollars in maintenance and repairs. You simply pay for the power, and we take care of the rest. Our comprehensive service package features the Sunrun Guarantee, which includes best-in-class monitoring, free equipment replacement, and system repairs including parts and labor, and routine maintenance.

Panel manufacturer
The price of your panels will depend on the manufacturer. Sunrun partners with LG, a world leader in solar technology and panels. Striking the right balance between quality, efficiency and affordability, LG offers some of the best solar panels on the market today. 14
For a given manufacturer, higher efficiency panels cost more. 5 The good news is that the highest efficiency panels aren’t always needed, especially if your roof gets plenty of sun.
Your state
Another factor in determining your total home solar system cost is where you live. Here are the states with the lowest and highest average solar system costs:
| Florida: 9,198 – 11,970 | Rhode Island: 13,104 – 15,792 |
| Arizona: 10,332 – 12,096 | New York: 12,264 – 16,044 |
| Maryland: 10,332 – 12,768 |
after 30% federal solar tax credit 5
Just because a residential solar system costs more in a given state doesn’t mean it’s any less cost effective. 5 Local incentives can make a huge dent in solar installation costs even in the most expensive states.
The three most common kinds of solar panels are monocrystalline, polycrystalline and thin film. 6 Here are the essential features of each:
| Monocrystalline | Monocrystalline are the most efficient on the market today, which means you need less panels to fulfill your energy needs. Monocrystalline solar cells are single-crystal silicon, giving electrons greater freedom to move and create electricity. 7 These panels are typically black, giving your roof a sleeker aesthetic. Monocrystalline panels also maintain their efficiency for longer and usually come with a 20 to 25 year guarantee. 6 |
| Polycrystalline | Polycrystalline panels are made with many fragments of silicon. 7 While this makes them less efficient, it creates less waste in production and are more affordable. 6 They also tend to have a blue tint, likely the most recognizable feature of solar panels today. |
| Thin-film | Unlike monocrystalline and polycrystalline panels, thin-film isn’t made of silicon. Instead, it’s layered with photovoltaic materials on metal or glass. 8 While the least expensive option, thin-film isn’t as efficient and likely won’t cover the average household’s energy needs without taking up lots of space. 6 |
The type of solar panel you choose will factor into the price of the system. But remember that if you decide to lease, you’ll be paying for the power rather than the panels. The cost of solar will come down to the amount of solar power you’re projected to use under your lease agreement.
Solar panel mount types
While solar panels are the main component of a solar system, how you mount the panels will also affect the cost. There are three mount types: 6
| Fix-mount | 10–15 per mount | Fixed-mount are stationary and can’t be moved to capture more sunlight, making them less efficient than other mounts. However, they’re also the least expensive. In addition, states with consistent sunlight such as Arizona and California are the least affected by this. |
| Adjustable-mount | 50 per mount | Adjustable-mounts can be tilted to maximize solar energy production. This mount type can also lay your panels flat during a storm to avoid wind damage. While they’re more expensive than fixed mounts, adjustable-mounts might make the most sense for regions with more seasonal climates and less space to maximize energy production. |
| Tracking-mount | 500–3,000 per mount | Tracking-mount follows the sun’s arch for maximum energy production. Even though they’re the most expensive, track-mounting could add 45% in energy production and might be worth considering based on your location. However, track mounting also requires more attention and will be much more costly to maintain. |
Calculate Solar Panel kWp (KWh Vs. KWp Meanings)
Solar power is certainly a great way to save on some electricity bills and move your home toward a greener, more sustainable future. That said, calculating your power needs and designing a solar system to match those needs can be confusing, and there are a handful of important factors to understand.
One of these is the KWp rating or kilowatts peak. This is the rate at which your solar system generates energy at peak performance, such as at midday on a sunny day.
But how do you calculate your solar system’s kWp?
It can be challenging to calculate your solar system’s kWp, as it’s difficult to predict the exact power output of your system due to factors like component efficiency, temperature, location, and weather.
There are some methods, though, and in this article, we’ll be covering the following:
- The standard for determining kWp
- Calculating the kWp of your system
- Determining the kWp you need in your home
- Examples of typical solar installations
Calculating the correct kWp of your solar system can be confusing, but we’re here to help! Read below for our in-depth guide on calculating your solar needs and output.
What is kWp in a solar panel?
Put simply, kWp is the peak power capability of a solar panel or solar system. The manufacturer gives all solar panels a kWp rating, which indicates the amount of energy a panel can produce at its peak performance, such as in the afternoon of a clear, sunny day.
kWp, or kilowatt peak of your panel, is calculated with a standardized test that all solar panel manufacturers must adhere to, with standardized radiance, temperature, and size. These standards are as follows:
- Solar radiation of 1,000-watts/m 2
- Ambient temperature of 25-degrees C
- Clear skies
This standardization makes it possible to accurately compare solar panels and their performance when choosing which to purchase for your needs.
kWh vs. kWp
kWh, or kilowatt-hours, refers to an appliance’s energy in one hour. A kilowatt equals 1,000-watts, so if you use a 1,000-watt appliance for one hour, you’ll be consuming 1 kWh of energy.
If your solar system has a kWp of 1,000-watts, for example, your kWh to kWp ratio is 1:1. Of course, this is at peak performance, so the ratio is, in reality, a fair bit lower.
A 1 kWp system operating at peak performance would supply you with one kilowatt of power, but this depends on many factors like efficiency, temperature, and weather, so these two metrics are certainly important but somewhat unrelated.
How do I calculate my solar panel output?
Calculating solar panel output is fairly simple but depends on your panels’ efficiency, location, and the amount of sunlight hitting the panels daily.
For example, people living in equatorial regions will have far more sunlight per day than those closer to the poles.
The first metric to check is your solar panel’s wattage rating. If you’re using a 300-watt panel, your panel will be kicking out 300-watts (maximum kWp) under perfect conditions, but again, likely a bit less on average due to temperature, weather, and placement.
A simple formula for calculating solar panel output is:
- Average hours of sunlight x solar panel wattage x 75% (for dust, pollution, weather) = daily wattage output.
So, if you’re getting 6 hours of sunlight per day — on average — with a 300-watt panel, you’ll be getting 1,350 watt hours per day.
How many units does 1kw of solar panels produce?
Typically, one “unit” of solar energy equates to 1kWh, which is what a 1kw system is capable of producing in 1 hour under perfect conditions. This means you would again use a very simple formula, system capacity (1kw) x hours of sunlight.
- Going back to our example above, 6 hours of sunlight multiplied by your system capacity (1kw) would give you roughly 6 units, or 6 kWh of energy per day.
How many kWh does a house use per day?
On average, the daily kWh consumption for an average home in the United States is just under 29 kWh hours. This accounts for using energy-heavy appliances like geysers and heating, which can be substantially reduced.
This energy usage also depends on the size of your home, the building materials of your home, and the number of residents. Also, people in colder climates naturally use significantly higher power to warm their homes.
How do I calculate kWh?
Calculating the kWh usage of your home is simple: you take the total kWh on your electricity bill and divide it by the days the bill covers. Again, this may fluctuate during the year, but it’s a good ballpark figure.
You can calculate the amount of kWh your appliances use based on how long they are on. For example, if you use a 1kWh appliance for 3 hours, that appliance will use 3 kWh per day.
How do you calculate PV per kWh?
Now that you know how much kWh your home consumes, you’ll naturally need to calculate how many panels you’ll need to generate sufficient power.
Let’s assume your home uses 10 kWh per day. You’ll need at least 10kWh hours of solar panel output to match this, but most likely a lot more.
This is because no solar panel — or solar setup for that matter — is 100% efficient, plus, this kWh rating is under perfect conditions, which are not guaranteed.
- If you use 10 kWh per day, you’ll need at least 12-15 kWh of solar power output to account for losses.
As an example, a 200-watt solar panel will produce roughly 200-watt hours per hour under perfect conditions, or 1,200-watt-hours (1.2 kWh) per six hours of sunlight.
You’ll need at least ten of these panels to cover your daily energy usage with solar power completely.
How many solar panels do I need for 50 kWh per day?
As we’ve already discussed, solar panels are subject to efficiency issues, weather, sun hours, and location, so it’s almost impossible to give an exact answer. However, there are some rough calculations we can do to get a fairly accurate answer.
Let’s assume you’re using 200-watt panels, with around 4-hours of sun per day(just to be safe), you’ll be getting roughly 800-watt hours (0.8 kWh) per day, per panel. This would mean you’ll need around 62, 200-watt panels to generate 50 kWh per day.
How much power does 5kW solar produce?
On average, a 5kW solar system will produce around 20kWh per day, depending on your location and sunlight hours per day. You may find the system producing more in summer months, 25-30kWh, and less in winter, 15-20kWh.
Is 1 kW enough to run a house?
Considering the average household in the United States uses roughly 29kWh per day, and 1kW of solar will give you 4-5kW of power with 5 hours of sunlight, this will not be enough for most homes.
That said, it can help lower your dependence on mains power and save you money on electricity bills.
It also helps to look at your energy requirements and usage and see where you can save on power. For example, using a solar geyser to heat water, a gas fridge, and a stove and heating your home with a fireplace or gas heater will save a ton of power overall.
I have a 1kW solar system in my home that provides me more power than I need since I save on energy usage by using gas appliances and a solar geyser. This is enough to run lights, computers, a TV, and other small appliances.
How much is a 30 kWh solar system?
For a 30 kWh solar system, the cost depends on several factors:
You can save quite a bit of money if you install the system yourself, but this is certainly tricky. Installation costs will vary widely depending on who does the installation for you, but for a system this large you can expect to pay around 10,000 for installation.
In general, solar panels cost around two or three dollars per watt. Taking into consideration the quality of components you choose, installation, and your location, you can expect to pay anywhere from 60,000 to 80,000 for a 30 kWh solar setup.
How many solar panels do I need for 2000 kWh per month?
2000 kWh per month equates to roughly 66 kWh per day. Again, let’s go with 200-watt panels (as these are some of the most common), with around 4-hours of sun per day(just to be safe), you’ll again be getting roughly 800-watt hours (0.8 kWh) per day, per panel.
In order to produce 66 kWh per day of power, you’d need 82, 200-watt solar panels.
How much should I pay for a 6kW solar system?
As mentioned earlier, the average cost per watt for solar setups is 2-3 in the US. This costs roughly 12,000, but you’ll also need to consider installation, bringing the cost up to roughly 14,000-15,000.
1 kWp solar panel size
If you wanted to run a solar system with a panel output of 1 kWP, you’d need 1 kilowatt of power. 1 kilowatt would be the peak capability of your panels on a day with full sun, which is 1,000-watts. Solar panels usually come in 200-350 watt units, although some higher power panels are available too.
For 1 kWp, you’d need five 200-watt panels, four 250-watt panels, or three 350-watt panels. Remember, this is your solar array’s peak performance rating, so your panels will only achieve this kind of output for a few hours a day if it is clear and sunny.
How to calculate solar panel efficiency
Most solar panels have an efficiency rating of between 10% and 23%, which the manufacturer usually indicates.
Efficiency also depends on the type of panel you’re using (monocrystalline vs. polycrystalline), where your panel is facing, and much heat it is generating (solar panels should never be laid flat on a roof, as they lose efficiency exponentially when they overheat.)
The efficiency rating of a solar panel refers to its ability to convert sunlight into usable energy.
So, if a panel has an efficiency rating of 15%, it can harness 15% of the photons that hit it. Due to real-world weather conditions and placement, a solar panel rarely produces its full wattage output rating.
To calculate the efficiency of your panel, you’ll need to look up the amount of sunlight that hits the earth in your particular area. Multiply this amount by the surface area of your panel, divide the maximum kWp of your panel by this number, and then multiply it by 100% to get an accurate efficiency rating.
Let’s say 1,000-watts per square meter of sunlight is hitting your area, and if you have a 1 square meter panel, you’ll end up with 1,000-watts exactly. If you have a 200 kWp panel, the efficiency will be roughly 20% (negating any other environmental factors, of course.)
Conclusion
The first step in designing a solar setup for your home is to calculate how many kWh or kWp you’ll need. Check your electricity bill for your monthly use, and divide that number by 30 to calculate your daily needs.
Of course, you can always reduce your electricity usage or use solar power to augment your mains power and reduce your electricity bills.
Once you’ve calculated your power requirements, you can design a solar system that can provide you with all or even just a portion of your power needs.
Hopefully, we’ve helped you with all the calculations you need so you can get started going off-grid, today!
How long do solar panels last?
How long solar panels last depends on their quality and how well looked after. In general, though, most solar panels will last between 25 and 30 years, with the most expensive models having a life expectancy of 40–50 years. That being said, solar panels will still produce energy after this time, although their capability will have declined significantly.
How do you set up a solar panel system?
The first step in setting up a solar system is determining how much power you need, and planning your solar system accordingly. After this, the setup is fairly straightforward;1. Gather all the required components together; panels, inverter, batteries, cables, etc. 2. Find a safe space in your home to house the inverter and batteries3. Fix the panels to your roof or a stand4. Connect the panels to your inverter or charge controller5. Connect your inverter to your batteries
What is required for solar panel installation?
Again, the first crucial step for any solar installation is calculating your power needs. Once you’ve done this, you’ll need to purchase the appropriate components. These include;1. Solar panels2. Batteries3. Inverter4. Charge controller5. Suitable cablesThese components are typically purchased separately according to your needs, but you can purchase ready-made solar kits that have all the components you need too.
Can I set up solar panels myself?
With a bit of basic DIY and electrical knowledge, you can certainly set up solar panels yourself, especially smaller systems. The setup can become somewhat complicated for large, high-power systems that are grid-tied, though, and you may want to get assistance from a qualified electrician.

How Much Power Does A 4.5 kW Solar System Produce?
Dec 29th 2022
If you’ve been around solar circles, you’ve probably heard about solar systems and the benefits they provide. You might’ve even heard terms like Watts, wattage, kilowatt-hours, and so on being thrown around.
But most likely, you’ve often been left wondering how these terms relate to you and your solar installation. In fact, you’re not alone, as plenty of people have a hard time understanding exactly how much power a solar system of a certain size (kW) can generate.
Here, we answer your questions, including:
Our answers to the above questions will empower you with the information you need to choose the system size that’s right for your home or business.
How much power does a 4.5 kW solar system produce?
To determine how much power a 4.5kW solar system will produce, you need to know what a 4.5 kW solar system is.
A 4.5 kW solar system usually refers to a solar installation with an array of solar panels with a total wattage of at least 4.5 kW or 4500W. The individual wattage of the solar panels in the array doesn’t change the amount of energy produced by the whole solar panel array.
So to calculate the amount of energy produced by a 4.5kW system you only need to know:
1.The system size, e.g., 4.5kW, 10kW, etc.
2.The peak sun hours in your area. You can find the peak sun hours for your area here. Please keep in mind that peak sun hours can still vary by region within a state.
Once armed with this knowledge, finding out how much power or energy your 4.5kW solar installation will produce is easy.
You only need to multiply your system size (4.5kW) by the number of peak sun hours in your region.
Amount of Power Produced(Wh) = System Size(W) Peak Sun Hours(h)
In the following examples, we are going to calculate the minimum amount of power generated by a 4.5kW system in three different states:
Example 1 – New York (3-3.5 peak sun hours)
4500W 3h = 13500Wh or 13.5kWh
Example 2 – California (5-7.5 peak sun hours)
4500W 5h = 22500Wh or 22.5kWh
Example 3 – Arizona (7-8 peak sun hours)
4500W 7h = 31500Wh or 31.5kWh
On average, a 4.5kW solar system will produce between 15000Wh to 22500Wh (15kW-22.5kW).
To find out how much energy a solar panel produces per day, multiply the panel’s wattage with the number of daily peak sun hours.
How much power does a 10 kW solar system produce?
We are going to repeat almost the same process we used above. We need to know our system size (10kW or 10000W) and the number of peak sun hours in your region.
Suppose you lived in an area that gets 5 peak sun hours each day, your 10kW solar installation would generate:
Amount of Energy Produced by 10kW System (Wh) = 10000W 5 hours
Amount of Energy Produced by 10kW System (Wh) = 50000Wh or 50kWh
With different peak sun hours, the same 10kW system will produce different amounts of energy. For example, under 4 peak sun hours, your system will produce 40kWh and under 3 peak sun hours, it will be 30kWh, etc.
According to the US Energy Information Administration. the average US household used approximately 30kWh or 30000Wh of energy daily. So a 10kW solar system is more than enough to power the average household away from a grid supply, provided your region gets at least 3 peak sun hours.
How much power does a 15 kW solar system produce?
We repeat the same process used for the 4.5kW or 10kW solar systems above.
We multiply the system size by the number of peak sun hours in your area. We will use 5 peak sun hours in our example below. If your region gets a different amount of peak sun hours, replace the ‘5’ with your region’s peak sun hours.
Amount of Power Produced by 15kW solar system = System Size (W) Peak Sun Hours (h)
Amount of Power Produced by 15kW solar = 15000W 5 hours
Amount of Power Produced by 15kW solar = 75000Wh or 75kWh
On average, a 15000W solar system will produce between 45kWh and 75kW of energy.
What is needed for a solar power system?
A solar power system is made up of a combination of devices that allow a household or business to power their electrical devices using power from the sun.
It consists of about 6 main components. Sometimes, some of these devices can be combined into a multipurpose device.
Solar Panels: Generates energy by converting light from the sun into DC electrical power.
Inverter: Converts DC electrical power from the solar panels or batteries into AC electrical power used by most appliances.
Converter: Converts AC electrical power from the grid into DC electrical power that is used to either charge your batteries or power DC appliances.
Charge Controller: Controls and regulates the incoming power generated by the solar panels so that it doesn’t damage the battery or batteries.
Battery or Battery Pack: Stores DC electrical power for use during the night (when the solar panels don’t work) or when there’s no grid supply.
Connectors: These are wires used to transmit and distribute electrical power between the different devices in the solar power system. An example is the wires that link your solar panels to the charge controller.
Of course, the above are not all the devices needed in a solar power system. Other crucial accessories are mounts, brackets, circuit breakers, fuses, bolts, racks, etc.
If buying various components seems daunting, we recommend you check out our Renogy solar kits which have everything you need to set up a working solar installation.
How many solar panels do I need for a 4.5 kW solar system?
Many often find themselves in the trap of getting the most powerful solar panel with the highest wattage instead of getting the most suitable solar panel for your installation.
At the end of the day, what matters is the total wattage of your panels instead of the individual wattage of the panels in the system. Different panel wattages only mean you need more lower-wattage solar panels to generate the same amount of energy as a few higher-wattage panels.
Take a look at the table below that has how many Renogy panels of each wattage you need to build a 4.5kW solar system.
What can I run on a 4.5 kW solar system?
If the total wattage of your solar panel system is 4500W, you can generate anywhere between 13500Wh and 31500Wh of energy in the US.
The 31.kWh is generated in states like Arizona and California which can get 7 peak sun hours. In contrast, 13.5kWh is generated in areas like Pennsylvania and Massachusetts that get a low 3 peak sun hours.
Using the minimum 13500Wh as our guide post, which is about a third of the average energy used by a US household. We see that we can power almost any device that’s below 3000W depending on the inverter’s size.
Here’s a table with common household devices, their wattages, and how long a 13500Wh energy capacity can power that device.
With the right adjustments and conservation methods, a 4.5kW solar system should be able to power your home.
If you live in areas like Pennsylvania, Alaska, and Connecticut that get low peak sun hours, additional supply from the grid might be needed. That being said, the 4500W system can still reduce your power utility bills significantly.
If you live in areas like California, Arizona, and other areas that get at least 5.5 peak sun hours, it’s possible to power all the devices in an average US household as if it was on the grid. However, it’s recommended that you don’t use high-wattage devices like stoves on your solar circuit due to their high energy demand from your batteries.
How much does a 4.5 kW solar system cost in 2022?
Below you will find a table containing the costs of 4.5kW solar systems composed of different panel wattages. The individual panel wattages range from 100W to 550W, which is typically the range suitable for fixed rooftop or ground installations.
Our calculations are done using the default list prices, so you can take advantage of our promotions to get a sizable discount during your purchase.
If you look at the above table closely, you find that the Renogy 320W Monocrystalline Solar Panel offers the perfect blend of size, cost, and the number of panels.
Do note that the listed in the table above do not include the cost of the inverter, battery pack, charge controller, and other accessories needed for a solar installation. You will need to buy these items separately if you are not purchasing a pre-matched solar kit.
For the inverter, it’s wiser to buy an inverter charger that combines the features of both an inverter and a converter. An inverter charger not only powers your home, but also charges your battery using the grid supply. Some inverter chargers also have a built-in charge controller for solar panel charging.
We recommend buying an inverter-battery set consisting of one 3000W 12V PSW Inverter Charger and three 12V 100Ah Lithium Iron Phosphate Batteries. This set costs approximately 3,000 but could be much lower due to our buyer discounts. Alternatively, you could opt for more affordable AGM or Gel batteries of equal voltage and capacity.
Altogether, a 4.5kW solar power system with 14 320W panels, 1 3000W 12V inverter charger and 3 12V 100Ah batteries can cost around 8,600. This value can be lower or higher depending on your final purchasing decisions.
