How Much Do Solar Panels Cost?
Saving money is Smart. Going solar is a Smart investment. Everyone asks about cost, but if your goal is to maximize how much you make from your investment, then the most important questions are “how much money will you save each month on electric bills?” and “how quickly does your solar system pay for itself?”
To calculate that payback period, you need to account for factors like the quality of your solar system, how much sun reaches your solar panels, whether you lease or own the system, the cost per watt, available tax credits, and quite a few more. Reputable solar providers can calculate those factors to show you how quickly your system will pay for itself in electric bill savings.
But understandably, you want to know how much it will cost to put a solar system on your roof. Below we’ll break down cost and some of the other major factors that you should consider.
Estimating how much home solar panels cost in 2021
One of the first questions someone interested in home solar asks is, How much do solar panels cost? It’s important to know there is not a one-size-fits-all answer because every home is different, and there are many geographic variables and federal and local tax incentives to consider.
The easiest thing to do is to contact a professional solar installer. The installer will give you a free evaluation that entails looking at your electricity bill to find out how many kilowatt hours of electricity your household typically uses and evaluating your roof and shading, to determine how many panels you’ll need. That, combined with local solar incentives your community may offer and the federal solar tax credit, will give you a full picture of how much your home solar system will cost. The good news is that no matter where you live, the cost of solar panels is coming down.
We look at the price per watt when figuring out the cost of your system, but you may find it more useful to think about the price of leasing a solar system separately from the price to own one. That’s because with a lease it’s important to think about how much you can save for each month of the lease, but when you own the system it’s more important to understand how quickly it can pay for itself.
What is the cost of individual solar panels?
Very few people are going to buy just the solar panels themselves, just like few people would buy the components of a car and build their own vehicle. We recommend you use a SunPower-approved installer for your solar system.
Yes, it’s possible to buy a single solar panel for as little as 100, but a solar panel does not operate in isolation. You need a system of hardware and software to generate electricity from the sun, including solar panels, an inverter, mounting hardware, wires and cables., It is also beneficial to have a monitoring system that tracks the production, energy use and savings of your system. And you need to consider the cost of installation and operation.
Once you get an estimate for the cost of your solar system, you should subtract the potential savings on your utility bill over time, including any incentives offered by your local or state governments. Then you’ll have a better understanding of how going solar will impact your finances.
What are the factors that affect solar panels?
The cost of a home solar system can vary, even in the same city, due to a range of factors, including the:
- Quality of the solar system
- Household’s energy needs
- Local weather
- Available roof space and shading
- Financing options selected (cash, loan, or lease)
To help you understand the price of going solar in your area, we’ve analyzed SunPower price quotes, as well as quotes gathered by third-party sources for thousands of homeowners across the country.
We found that the cost of installing a 5 kW solar system in the U.S. ranges from 11,150 to 46,100, or in other words, from 2.23 to 9.22 per watt. And that’s before considering the benefits of any available tax credits or incentives.
The chart below shows the average cost of a 5 kW home solar system in each U.S. state.
How do I know how much sun my roof gets?
The more direct sunlight your home receives, the more power the panels can produce. But there’s a little more to it than just sunlight. To see if your house is a good candidate for solar, try out a solar panel suitability checker such as Google’s Project Sunroof. Then set up an appointment for a solar consultation with an expert who’ll visit your home to inspect its orientation (solar panels facing south capture more energy), roof angle and tree shading to see if your roof will receive enough sunlight to meet your family’s electricity needs. SunPower’s solar consultations are free, online or in-person, and you can learn more about your home electricity needs and savings options.
SunPower panels are proven to be the most efficient on the market —not to mentioned unmatched at generating power in low-light situations—but, excessive shading will reduce the amount of power that can be generated.
It’s also important to know a SunPower Equinox ® solar solution has unique, factory-integrated microinverters in each panel. Meaning, if one panel isn’t producing energy because of shade, neighboring panels receiving more sunlight can still generate solar energy for your home.
What are the most efficient solar panels?
Remember that the adage, “You get what you pay for,” applies to home solar technology. Not all solar systems are alike. The quality of the technology matters in the long run. The durability, reliability and efficiency of solar panels can vary widely by manufacturer. If you settle for a conventional home solar system that might cost less out-of-, you can expect to see average (or below average) results and less savings over time. Watch these videos about the lifespan of SunPower® solar panels and their durability and reliability.
In short, SunPower panels are the most efficient home solar panels you can buy. A higher quality panel like SunPower’s might cost a little more upfront, but you’ll see a higher—and quicker—return on your investment in the long run. Our panels come with a 25-year Complete Confidence warranty and have an expected useful life of 40 years. And since they’re more efficient than other panels on the market, you’ll need fewer of them on your roof. Our panels produce up to 55% more energy in the same space over 25-years than conventional panels, ultimately saving you more money on your electric bill.
Industry measurements such as the Fraunhofer Center for Sustainable Energy Systems’ PV Durability Initiative can give you a better idea of a solar panel’s expected lifespan—a factor that can have a tremendous impact on the system’s lifetime value.
The superior efficiency and durability of high-quality panels can provide increased savings over time and lower maintenance costs. You can get a personalized SunPower solar savings estimate using our solar calculator, which lets you factor in variables like buying solar storage and/or having an electric vehicle.
What solar incentives or solar rebates are available?
There are many different tax incentives, subsidies and financing and billing solutions at the state and local levels that can make going solar more affordable. To see if you might be eligible for renewable energy incentive programs, visit the Database of State Incentives for Renewables Efficiency (DSIRE®).
If you purchase your solar system, you may qualify for the 26% federal tax credit (ITC). The full solar ITC is available to home solar owners through 2022. It drops to a 22% credit in 2023 and is scheduled to go away completely in 2024, so don’t put off buying solar for too long.

A 5,000 WATT( 5 KW ) SOLAR SYSTEM INFORMATION AND PRICING
A 5000W solar power system is a size that should easily offset a typical home’s electricity usage. If it doesn’t, then you’ve got one serious energy guzzler of a home and should really consider an energy audit before going solar! 5 kW solar systems are also the minimum system size you should be considering if you’re looking to add batteries to your system in the future. Here’s what you need to know about 5kw solar system price and other information.
How many solar panels will you need?
To make up a 5kW solar system, you need 17 solar panels, assuming you use 300W panels – that will actually give you 5.1kW. Each panel will be about 1.6m x 1m, so you’ll need at least 17.2m² of roof space.
How much electricity will a 5kW solar system generate?
A 5kW solar system will generate approximately 20kWh per day, depending on your location and a variety of other factors. The average home in Australia uses about 16kWh per day. Note that this does not mean installing a 5kW solar power system will automatically give you a 0 electricity bill, as most households use the majority of their electricity at night when the sun isn’t shining – I talk about this in greater detail here.
How much money will a 5kW solar system save?
You may be thinking: “If the 5kW system offsets my energy usage, then surely it’s going to wipe out my electricity bill?” Unfortunately it is not that simple! The amount the electricity companies will pay you for your solar energy (what’s known as a feed-in tariff) is, way lower than the price they charge you to buy the same electricity from the grid! Plus, there’s other costs on a bill such as supply charges, aka service charges. However, a 5kW solar power system is still an excellent investment. Let’s say you get paid about 8c per kWh for exported energy (some retailers offer more) compared to 30c per kWh to buy electricity back from the mains grid. Here’s 3 scenarios to show how the 5kW system payback works:
- Use all the solar electricity by the 5kW systems in your home. This is unlikely unless you have a mini aluminium smelter in your back garden – or you operate a small business from your home. If that were your situation, you would save approximately 2100 in the first year, and around 67,000 over 20 years; taking electricity inflation of 5% into account. Those are some serious savings.
- Export half the electricity: You would save about 1400 in the first year.
- Export all the electricity: You would save about 700 in the first year with a 5kW system.
How much does a 5kW solar power system cost?
The cost of a 5kW solar system will be around 10,000 before STCs, then you should get about 3,500 subsidy from STCs (aka the solar rebate), which takes a big chunk out of the up-front price. Taking into account the subsidy, expect to pay about 4,500 – 8,000 out of costs for a good quality 5kW system, depending on the components selected and the installer’s approach to installation. Here is a basic price range cost in USA
How long before a 5kW solar power system pays for itself?
If you are not exporting the energy and assuming you’ve paid a reasonable price for a 5kW solar system, then you should see a payback period of less than 5 years – so a fairly Rapid payback timeframe. But you can actually be cash flow positive from day one if you get cheap solar finance. It is very easy to finance the purchase so that your monthly energy savings are worth more that the cost of paying back the loan. It can be a laborious process to find a trustworthy solar installer to provide you with a good-quality 5kW solar power system at a reasonable price.
How is Powerwall Works
Powerwall gives you the ability to store energy for later use and works with or without solar to provide key security and financial benefits. Each Powerwall system includes at least one Powerwall and a Tesla Gateway, which provides energy monitoring, metering and management for the system. The Backup Gateway learns and adapts to your energy use over time, receives over-the-air updates just like the rest of Tesla’s products and is capable of managing up to ten Powerwalls.
With Solar When the sun rises, solar begins powering the home. When additional power is required within the home, the home can pull from the utility grid.
Powerwall is charged by solar during the day, when solar panels are producing more electricity than the home is consuming. Powerwall then stores that energy until the home needs it, such as when solar is no longer producing at night, or when the utility grid is offline during a power outage.
The next day when the sun comes out, solar recharges Powerwall so you have a cycle of clean, renewable energy.
Without Solar If your electricity rates vary throughout the day, Powerwall will charge when electricity costs are low and discharge when electricity costs are high, generating automatic savings. Powerwall will also provide seamless backup power by detecting grid outages and automatically becoming the home’s main power source.
Tips for 5Kw system Shoppers
Homeowners who get multiple quotes save 10% or more
As with any big ticket purchase, shopping for a solar panel installation takes a lot of research and consideration, including a thorough review of the companies in your area. A recent report by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) recommended that consumers compare as many solar options as possible to avoid paying inflated offered by the large installers in the solar industry.
To find the smaller contractors that typically offer lower prices, you’ll need to use an installer network like EnergySage. You can receive free quotes from vetted installers local to you when you register your property on our Solar Marketplace – homeowners who get 3 or more quotes can expect to save 5,000 to 10,000 on their solar panel installation.
The biggest installers typically don’t offer the best price
The bigger isn’t always better mantra is one of the main reasons we strongly encourage homeowners to consider all of their solar options, not just the brands large enough to pay for the most advertising. A recent report by the U.S. government found that large installers are 2,000 to 5,000 more expensive than small solar companies. If you have offers from some of the big installers in solar, make sure you compare those bids with quotes from local installers to ensure you don’t overpay for solar.
Use LFP battery acturly save the system cost.
People will normally think it is cost much higher to buying a Lithium iron battery storage system. While a Lead acid system cost much lower. But, ignor the cycle life for them. A qualified LFP battery system is rated 3000more life cycles at 80% DOD. while lead acid is 200 times game over. Then you will need to replace a new battery system. If you calculate based on each day expensive. You will find out. LFP battery system is much lower and more efficiency. OSM offer a standard 5000w battery system at 5Kwh a module. This allowd you upgrade for more capacity in future. Here is the product link: 5kwh OSM48100
Easy hang to the wall design.
Comparing all your equipment options is just as important
National-scale installers don’t just offer higher – they also tend to have fewer solar equipment options, which can have a significant impact on your system’s electricity production. By collecting a diverse array of solar bids, you can compare costs and savings based on the different equipment packages available to you.
There are multiple variables to consider when seeking out the best solar panels on the market. While certain panels will have higher efficiency ratings than others, investing in top-of-the-line solar equipment doesn’t always result in higher savings. The only way to find the “sweet spot” for your property is to evaluate quotes with varying equipment and financing offers.
For any homeowner in the early stage of shopping for solar that would just like a ballpark estimate for an installation, try our Solar Calculator that offers upfront cost and long-term savings estimates based on your location and roof type. For those looking to get quotes from local contractors today, check out our quote comparison platform.

How Much Power Does A 5kW Solar System Produce Per Day, Month, Year?
5kW is one of the most popular solar systems around. The key question here is how much power does a 5kW solar system produce per day, per month, and per year as in ‘5kw solar panel how many units per day?’.
We will teach you how you can adequately estimate how many kWh per day does a 5 kW system produce. Depending on how much sunlight you get (solar irradiance), a 5kW solar system can generate anywhere from 15.00 kWh to 22.50 kWh per day. That’s 5,400 kWh to 8,100 kWh per year.
In short, 5kW can produce more than 1,000 worth of electricity every year.
According to the US Energy Information Administration, the average annual electricity consumption for a U.S. household is 893 kWh per month (about 117,78/month). That’s about 30 kWh per day. Can a 5kW solar system produce 30 kWh per day? 5kW is a big system requiring about 17 300W solar panels and about 13 kWh batteries, after all.
Here’s how we will find that out:
We can adequately estimate how much power does a 5kW solar system produce per day using this basic solar output equation;
5kW Solar Output (kWh/Day) = Power Rating × Peak Sun Hours × 0.75
The key variable here is the Peak Sun Hours. Sunnier parts (south US, south of Europe) will, on average, get more peak sun hours (up to 6 hours/day) than northern parts (north US, north of Europe) with about 4 hours/day. The realistic output of 5kW will primarily depend on the sun exposure.
Example: In California with 5.5 peak sun hours per day, the 5kW solar system will produce 20.63 kWh per day or 7,528 kWh per year. In the UK or New York with 4 peak sun hours per day, the same 5kW solar system will produce 15 kWh per day or 5,475 kWh per year. That’s more than a 2,000 kWh difference with the same 5kW system (or a 270,79/year difference in electricity costs).
To help everybody out, we have designed a 5kW solar system output calculator (you’ll find it further on). It will give you an estimate of how many units does a 5kW solar system produce per day in your area. Here is how the calculator looks like:
Furthermore, we have calculated how much energy do 5kW solar systems produce (per day, month, year) in 4 – 6 peak sun hour areas and summarized them in the table below.
Before you use the calculator, let’s look at what is a realistic power output of a 5kW system in areas with 5 peak sun hours per day.
Average Power Output Of A 5kW Solar System Per Day, Month, Year (5 Peak Sun Hours)
To calculate the 5kW solar system power output, we use this equation:
5kW Solar Output (kWh/Day) = Power Rating × Peak Sun Hours × 0.75
We already know the Power Rating; it’s 5kW. At the end of the equation, you can see the 0.75 factor; that accounts for 25% losses an average 5kW system will suffer (due to inverter losses, DC, AC cable losses, temperature losses).
The key part – as we all know – is how much sun you get. That is measured in peak sun hours. On average, a 5kW solar system placed on the roof will get about 5 peak sun hours worth of sunlight.
When we understand and have all these 3 factors, we can calculate how much power does a 5kW solar system produce per day like this:
5kW Solar Output (kWh/Day) = 5kW × 5h × 0.75 = 18.75 kWh/Day
5 kW solar system in such an area can realistically produce 18.75 kWh a day. That’s 562.5 kWh per month and 6,843.75 kWh per month.
If we presume that the average price of electricity (in the US) is 0.1319/kWh, we can also calculate can a 5kW solar system save you per:
- Day. 18.75 kWh per day translates into 2.47 per day.
- Month. 562.5 kWh per month translates into 74.19 per month.
- Year. 6,843.75 kWh per month translates into 902.69 per year.
Now, not everybody lives in the area with 5 peak sun hours per day. Here is the solar irradiance map of the US that illustrates that:
To adequately estimate how many kWh a 5kW solar system on your roof will make, you can use this calculator:
kW Solar System Output Calculator
Check how many peak sun hours per day do you get. Insert that number in the calculator and you’ll get an estimate of how many units will your 5kW solar system produce per day:
As you can see, the daily kWh output of the 5kW solar system is dynamically calculated.
We have calculated kWh output for areas with different solar irradiance (number of peak sun hours) and summarized them in this table:
Table Of 5kW Solar System Outputs Based on Solar Irradiance
| 4 hours | 15.00 kWh/Day | 450 kWh/Month | 5,400 kWh/Year |

| 5.9 hours | 22.13 kWh/Day | 663.9 kWh/Month | 7,966.8 kWh/Year |
| 6 hours | 22.50 kWh/Day | 675 kWh/Month | 8,100 kWh/Year |
Hopefully you can now adequately estimate how many kWh per day is 5kW system capable of generating.
Quick note: How much power does a 5.5 kW solar system produce? It just produces 10% more kWh than a 5 kW system. You can use the chart above, add 10% to these kWh outputs, and get the correct results. Example: At 5 peak sun hours, a 5.5 kW solar system produces 20.63 kWh/day, 618.75 kWh/month, and 7,425 kWh/year.
