How does solar energy work and how do we use it in our homes?
There are no moving parts. No combustion takes place, nor is any noise generated. No space is required other than the surface of your roof. It requires no fuel, just sunlight. And despite all that, it can power your entire home and produce surplus power for you to export to your neighbors.
Yes, I’m talking about solar energy. The way it works seems so remarkable and mysterious that it seems almost like magic. But solar power production is actually pretty straightforward. And, believe it or not, the solar technology used in modern solar panels has remained essentially unchanged since the 1950s.
So, how does solar energy work? What has to happen for plain ol’ sunlight to be converted into electricity that can power your home appliances?
This blog will answer those questions. It will also look at how solar energy works at night, and the role batteries play in solar power systems.

Solar panels produce clean and renewable energy without having to rely on fossil fuels.
How does solar energy power your home?
In this section, we’ll explain the process by which homes can generate and use solar energy by using solar panels.
Usable solar power is produced in 4 steps:
- Solar panels generate DC electricity
- Solar inverter converts power into usable AC electricity
- Solar inverter supplies power to the home
- Excess solar power is exported to the grid
Solar panels generate DC electricity
Homes with solar power systems typically have between 15 and 25 solar panels installed on their roofs.
Each solar panel comprises a string of 60 or 72 photovoltaic cells, each made out of monocrystalline or polycrystalline silicon. The solar cells are designed to capture sunlight, and convert it into direct current (DC) electricity through the photovoltaic effect.
The amount of solar electricity that is produced depends on the strength of the sunlight and the design of the solar panel. As of 2023, individual solar panels typically produce around 400 watts each under optimal conditions.
Solar inverter converts power into usable AC electricity
Home appliances are designed to use alternating current (AC) electricity, so the DC power generated by the solar cells needs to be converted before it’s supplied to the home. This function is performed by a solar inverter.
Solar inverters can be installed in one of two ways:
- Module level: Here, small microinverters are attached to each individual solar panel to perform the AC-to-DC conversion.
- Centrally: A single-string inverter, also referred to as a central inverter, is installed. It receives the combined power from all solar panels before converting it. In such cases, small DC power optimizers can be attached to each panel for both improved performance and code compliance.
Although it often gets overshadowed by solar panels, the solar inverter (pictured) plays a crucial role in solar power production.
Solar inverter supplies power to the home
The inverter will then feed AC power at the required voltage (120V/240V) to your circuit board; this power is now available to service any electrical loads within your property.
With grid-tied solar power systems — the most common type of solar system installed in homes — you can, at any time, use either solar power, grid power, or a combination of both.
If the loads in your house are greater than the power supplied by the inverter, then your loads may be met by a combination of sources: partly from your rooftop solar power, and partly from the electrical grid.
Excess solar power is exported to the grid
If you have solar panels installed, it’s common to generate more solar power than your total required electrical loads (i.e. your energy needs). When this happens, the excess energy flows out from the home to the electric grid via your utility meter.
The utility meter will need to be a special “net meter”, which can keep a separate record of what electricity you export to the grid and what you consume from the grid.

How does a solar energy system work at night?
Solar panels need sunlight to generate electricity, but we all know that the sun doesn’t shine at night. To service your electrical loads after dark, a grid-tied solar panel system. the most common type of solar system. relies on power imported from your utility company.
Thankfully, there’s a good chance you won’t have to pay for much, or any, of the electricity you import at night. This is the case if you live in a state with 1:1 net metering, which is currently 38 out of 50 states. Here, the surplus power your system exported during the day is used to cancel out the cost of your electricity imports at night.
This video explains how a grid-tied solar system works by exporting energy during the day and importing energy at night.
How does battery storage work with solar energy?
Up until now, we’ve only discussed the most popular type of solar installation in the United States, grid-connected solar systems.
You may have noticed that these systems operate without any batteries. When the grid is available, as it is for most people, the addition of batteries to a home solar energy system is optional.
Furthermore, buying solar battery storage usually doesn’t make economic sense. Battery storage solutions are expensive and have relatively short lifespans, so they don’t usually pay for themselves.
That said, battery storage solutions are rising in popularity, aided by the emergence of versatile lithium-ion solutions like the Tesla Powerwall.
Here are the two common scenarios where homeowners choose to use battery solutions with their solar panel systems:
Scenario 1: Using batteries as part of an off grid system
Some people use solar energy to meet all their power needs; this is either because they’re seeking an off-grid lifestyle, or because grid connections are either unavailable or expensive to connect to (often the case in remote areas).
In such cases, homeowners pair their solar panels with battery storage to create an off-grid solar system. This allows them to store their excess daytime solar power for nighttime use.
Off-grid solar systems typically use lead-acid batteries, similar to those used in car batteries. They are the most affordable battery solution, and as such, are the preferred option when large amounts of storage are required.
Scenario 2: Using batteries for backup power
Homeowners living in blackout-prone areas are increasingly looking to battery storage as a power backup. They’re quieter and cleaner than traditional diesel generators, and don’t require going out and buying fuel.
Nowadays, most people buying batteries for backup power opt for newer lithium-ion options like the Tesla Powerwall or sonnenCore. These batteries have a small footprint and can easily be set up to function as an independent power backup in the event of a grid outage.
However, it should be noted that battery solutions are expensive and have short lifespans, with warranties of just 5-10 years. The economics improve a bit in locations like California where you can take advantage of state battery purchase incentives and use Time of Use (TOU) rates to see some savings.

Can I Use Solar Panels to Completely Power My Home in 2023?
Texans bask in the constant presence of the sun all summer long. But beyond serving as source of beautiful sunsets and seemingly perpetual heat, we rarely stop to consider other ways the sun affects our lives.
The concept of green energy as a way to provide power for our planet without using fossil fuels is increasingly a topic of public discussion. As awareness of green energy options grow, more and more people are looking for alternative energy sources to power their homes, which brings up a multitude of questions. In the case of solar energy, the two most commonly asked questions are:
The short answer to both? It depends. It’s based on a host of factors including, how much energy you use in your home and how much sun hits your roof on a regular basis. While itstill may be too expensive for most people to install solar panels on their homes, for the panels and installation are coming down. Chariot exists to offer 100% solar energy at competitively priced rates without the need for personal panels.
But before you call your nearest solar panel installation company to get a quote for your home, it’s essential you understand some crucial details about solar panels and solar energy.
The Falling Price of Solar Energy
Currently, solar panels are one of the more easily accessible forms of renewable energy. Solar energy attracts people in large part because of its many benefits, ranging from significant reductions in greenhouse gas emissions to increasing home value by an average of 15,000. With enough panels installed in Texas to power more than 350,000 homes, it is no longer uncommon to see solar panels affixed to the roofs of residential homes and businesses.
This expansion is also due to the falling price of generating solar electricity. Solar decreased by 34% in Texas from 2014 to 2019. This decrease is even more dramatic across a longer time frame, as solar panel installation costs in the United States dropped by 70% from 2009 to 2019. In response, demand for residential solar panels and solar power in general has grown tremendously.
How Many Solar Panels Are Needed to Power My Home?
The average home in the U.S. uses 10,400 kWh of electricity per year. If you install the average 250-watt solar panel, you’d need around 28-34 solar panels to generate enough energy to power your entire home.
However, unlike the traditional utility grid, which is automatically connected to your home during construction, solar panel installation is a highly individualized process – something which also drives its price. We recommend taking these three steps to determine whether solar panels could be a good fit for you:
- Determine your electricity consumption in kWh. You can find this information on your electricity bill, or you can estimate it here.
- Divide that number by the solar panel production estimate. The exact estimate will vary depending on your location and property (e.g. tree coverage and regional sunshine). You can obtain a reasonable range by using 1.31 (Arizona) and 1.61 (Maine), the highest and lowest production ratios of the US, as guides.
- Divide that number by 250 – the wattage of an average solar panel – to determine a range of how many solar panels you may need in order to generate 100% of your home’s electricity needs.
- 11,000 kWh of annual electricity usage / 1.31 (since we live in Texas) = 8,396.9
- 8,396.9 / 250 = 33.58 » 34 panels.
While this estimate should not replace a professional evaluation, it can provide a useful rough idea to indicate the feasibility of solar panel installation for your house.
How Much Will It Cost to Install Solar Panels at My Home?
Though installation costs are dropping, an average installation will likely run you upwards of 10,000 – even after a 30% federal tax credit. For many, the cost alone makes the notion of completely powering homes through solar panels difficult. And that’s before you remember that Texas Retail Electricity Providers usually produce electricity much more cheaply than their residential power counterparts.
There is no doubt that solar panels will continue to drop in cost and increase in productive capacity in the future. But the majority of homeowners with solar panels don’t use them as the exclusive source of residential power. Instead, they are connected to the utility grid in a process called net metering (NEM). Net metering is a fantastic option for people who want to decrease their electricity bill while increasing their environmental friendliness.
This unique billing arrangement follows this pattern:
- A household utility meter monitors how much electricity is consumed by the household and how much electricity is generated by the solar panels.
- On either a monthly or yearly basis, that household is only responsible for paying its net consumption – its electricity consumption beyond what was generated by the home’s solar panels
- This creates opportunities for the most electricity-conscious households to be compensated by their utility company.
However, this setup is very rare. Though a self-sufficient, off-grid solar panel system remains a challenging feat, there are other ways to use green energy to power your home.
How a 100% Green Electricity Plan Is a Great (If Not Better) Alternative to Solar Panels
With its perpetually sunny climate, Texas ranks in the top 10 U.S. states in its cumulative solar capacity. As a result, the Texas solar industry has grown rapidly in terms of electricity generation and the number of people it employs. With it, household enthusiasm for solar panels has also increased. However, the two main concerns people have when it comes to solar panel installation are production capacity and costs.
Solar panels in residential settings currently face limitations since most homes have no way of storing extra solar power on sunny days when solar panels create more electricity than the home can use. Thankfully, further technological progress will likely address this storage problem, as it plagues the entire industry.
In regard to costs, regular electricity companies can offer lower rates on traditional electricity plans than those powered by solar energy because of an economic concept called economies to scale. In essence, the costs for each additional unit of output decrease as more output is created. In other words, because more households are connected to the Texas electricity grid than use solar panels, the average cost of electricity is lower for each household than it would be with individual solar panels.
Chariot Energy is striving to solve both issues. We build enormous solar farms that power the electricity we deliver, which addresses the economies of scale issue. This way, you can use 100% green energy in your home without the challenges of solar panel installation and at rates just as affordable as regular Texas electricity companies. Plus, despite decreased costs, it can take the average U.S. homeowner nearly 8 years to break even on solar panel installations. You don’t have to wait that long. Support the industry now and enjoy the benefits of 100% solar energy today!

Fact vs Myth: Can Solar Energy Really Power an Entire House? [2023 Update]
One of the most frequently asked questions by homeowners in regard to solar power is, “can it really power my entire house?” The answer to that is actually quite simple – yes, solar can indeed power your entire home. But explaining exactly how solar energy can power the entirety of your home is a little more complicated.
According to the United States Solar Technologies Office. “the amount of sunlight that strikes the Earth’s surface in an hour and a half is enough to handle the entire world’s consumption for a full year.”
With the sun delivering an awe-inspiring amount of energy to the earth on an almost hourly basis, it stands to reason that solar energy can indeed power an entire house. Let’s take a deep dive into how exactly this happens and how you can make estimated solar calculations at home.
How Does Solar Energy Work?
Simply put, solar panels work by capturing particles of light (or photons). These photons break electrons free from their atoms, knocking them apart, and generate what we know of as the flow of electricity.
Now, this statement may sound complicated to varying degrees based on how much science you remember from back in high school, but the main takeaway is that sunlight is converted to energy through a seemingly complex, but actually surprisingly simple process which involves capturing the sun’s energy, and turning into electricity. Once the energy is generated, it’s used to power devices, products, and homes.
If you want to learn more about the science of solar energy, take a look at our blog on frequently asked questions in regards to solar energy.
How Can Solar Energy Power Your Whole House?
So, can a home solar system really power your entire house? As we’ve stated, yes! But, it does depend on a few variables that you’ll want to take into consideration when deciding to go solar. Mostly, these variables are used to determine the power output levels and the number of solar panels that your home requires to meet your energy goals. In this case, we’ll explore the goal of running your whole house entirely on solar power.
Every home is different, and every home will require a unique amount of solar panels in order to effectively convert the sun’s energy into the energy you can use to power your home. At SunPower by BlueSel, we understand how to install your panels at the perfect angle, in the perfect spot, to maximize sun intake. Installing your solar panels in the perfect spot can make a big difference in regard to energy.
HowStuffWorks.com explains perfectly how solar panels can power an entire house:
“As solar panels protrude from the precipice at various angles, they capture whatever sunlight is available, and convert it to DC power. An inverter converts the DC power to AC power (which is what we use to power electronic devices). And for people who want to completely power an entire home with the sun’s rays, there are systems available to convert and store extra power in the form of battery energy.”
What’s Your Home’s Monthly Energy Consumption Rate?
According to U.S. Energy Information Administration. “in 2019, the average annual electricity consumption for a U.S. residential utility customer was 10,649 kilowatt-hours (kWh), an average of about 877 kWh per month.”
For the sake of simplicity, let’s round that number up to 900 kWh per month, and let’s assume that this number applies to most residential properties in the United States. If we divide 900 by 30, we can determine that most homes consume 30 kWh per day or 1.25 kWh per hour.
However, it’s important to remember that this number does vary depending on your home’s size and the amount of household energy consumption activity. You may also find your home’s specific energy consumption rate listed on your monthly electricity bill. So, be sure to check that out before making your own calculations.
How Many Hours of Sunlight Does Your Home Receive?
After determining your household’s monthly energy consumption, you’ll also want to figure out how many hours of peak sunlight your home can expect to receive.
Now, we understand that this number varies day-to-day, especially in Massachusetts, but making an educated estimate and then using the equation outlined below will allow you to determine a rough idea of the power required before consulting a professional solar installation company.
As a SunPower Master Dealer, we’ll use their comprehensive, yet straightforward equation to determine how many watts of power your home would need per day to run off solar power.
“Multiply your hourly usage by 1,000 to convert your hourly power generation to watts. Divide your average hourly wattage requirement by the number of daily peak sunlight hours for your area. This gives you the amount of energy your panels need to produce every hour. So the average U.S. home (900 kWh/month) in an area that gets five peak sunlight hours per day would need 6,000 watts.” (source: SunPower )
What Type And How Many Solar Panels Does Your Home Need?
Depending on the maker, solar panels come in all different shapes, sizes, build qualities, and power outputs. You’ll want to speak in-depth with a professional solar system installation consultant to determine the best and most efficient solar panels for your home. However, for today’s article, we’ll use SunPower’s A-Series Solar Panels as our example.
Panels range in wattage capacities with conventional solar panels typically starting at around 250 watts per panel. SunPower’s A-Series panels produce up to 400 watts per day per panel in peak conditions. Therefore, if we divide the energy needed to power the average home, 6,000 watts, by the 400 watts produced by each panel, we would determine that the average home requires at least 15 A-Series panels to run entirely off of solar energy in peak conditions.
Professional Solar Installation Consultations
While these numbers can give you a handy pen-and-paper estimate on what your home requires to run entirely off solar power, it’s necessary to consult with a professional solar installation expert. With many specific variables to consider (such as roof condition and angle, nearby shading, daily sun exposure, home size, etc.), you’ll want to ensure that professionals determine the most accurate data. From here, you can decide whether or not solar power is suitable for your home.
Enjoy all the benefits of a solar energy system while reducing your carbon footprint on the planet. Solar energy can power your entire home, as long as the right company is working with you to install your panels.

Solar Panels for Home (Guide)
Installing solar panels for home energy production is becoming more popular because it gives homeowners the ability to generate their own green, clean electricity from a renewable resource. A residential solar power system allows a homeowner to power their home with the electricity their solar panels generate, which lowers the amount of energy they use from the grid. Additionally, since solar panels don’t release greenhouse gasses or carbon emissions, they are very environmentally friendly, especially compared to energy sources that rely on fossil fuels.
With this article, we want to provide a helpful guide to the basics of solar panels for home use. We’ll discuss what solar panels are, how they work, the different types of solar panels, what solar looks like, why you should invest in solar, and then answer frequently asked questions about the technology.
What Are Solar Panels?
Solar panels, also known as photovoltaic (PV) panels, convert light from the sun into electricity. When exposed to sunlight, electrons in the solar panel move around, and this movement can be turned into electricity, known as solar power or solar energy.
Since solar panels are powered by the sun, they only work during the day and don’t produce electricity when the sun isn’t out. At night, your home draws power from the electricity grid operated by your local utility company, or from your battery storage system, if you have one installed. Very few homes in the U.S. are completely off-the-grid, even when they have solar power.
How Solar Panels Work
The short answer is that materials known as semiconductors allow solar panels to generate an electric current when exposed to sunlight. The science behind generating electricity with solar panels is called the photovoltaic effect, which was first discovered in 1839 by Edmond Becquerel.
The process looks like this:
- Photovoltaic cells in the solar panels absorb energy from sunlight.
- The sun’s energy causes electrons to move around in the cells, creating direct current (DC) electricity.
- Wiring captures that DC electricity from the surrounding cells, and moves it out of the solar panel.
The amount of electricity solar panels produce from sunlight is referred to as solar efficiency. The average efficiency rating of modern solar panels is between 15 and 20 percent, while high-end models can be over 20 percent efficient.
Once the DC electricity has been captured, it is then converted to usable alternating current (AC) electricity with the help of inverter technology. AC electricity, which is used by most home appliances, flows through the electrical panel and is distributed throughout the home to power electronic devices.
Any excess electricity produced by the solar panels is either stored in a battery or fed back into the electric grid.
For a simplified explanation of how solar panels work, check out Explain Like I’m 5: Solar Panels.
Types of Solar Panels
There are three major types of solar panels: monocrystalline, polycrystalline, and thin-film. Both monocrystalline and polycrystalline panels are made from crystallized silicon, whereas thin-film panels are made of thin films of semiconductors deposited on glass, plastic, or metal.
Each type of panel has its unique attributes, advantages, and disadvantages. The type of solar panel used for your solar power system will depend on several factors specific to your home.
The following are some of the distinguishing features of the solar panel types, along with the pros and cons of each:
- Monocrystalline: The most efficient, high-performing panel you can install on your home. Its black color is aesthetically pleasing, but this panel type is typically the most expensive.
- Polycrystalline: Less efficient than monocrystalline, but it also costs less, making this blue-colored panel a frequent choice for the budget-conscious.
- Thin-film: The lowest performance efficiency of the three, but it’s more portable, lighter in weight, and has greater aesthetic appeal.
What Do Solar Panels Look Like?
You may have seen black and blue solar panels, and wondered what the difference is.
Monocrystalline panels are made of high-quality crystals, and during the manufacturing process, the silicon is formed into one (mono) large crystal, which appears black to the human eye. Because of the properties of this single crystal structure, they are more energy-efficient. Thin-film solar panels, similar to monocrystalline panels, are also black and do not vary in color.
Polycrystalline panels are made of many smaller and separate crystals, and that structure produces a confetti-type appearance that appears blue to the human eye.
The actual look of your solar panels will vary depending on how and where they are arranged on your roof. They’re installed in what’s called a solar array, or a collection of multiple panels that generates electricity as a system. The shape and design of your arrays can depend on the size of your roof, the shading your roof receives, and where the panels should be arranged to produce the most electricity.
The number of solar panels you need also depends on many factors, including the size of your electricity bill, the physical location of the arrays, and the direction in which they face.
Types of Home Solar Power Systems
There are three different types of home solar power systems: grid-tied, hybrid, and off-grid.
- Grid-Tied: The most common system type, where rooftop solar panels produce DC power that is then converted into AC power with the help of an inverter. The home remains connected (or tied) to the grid, and if the solar panels don’t produce enough electricity to power the home, it can draw extra power from the grid.
- Hybrid: Includes a battery that stores excess energy produced by solar panels. When the solar panels can’t provide all of the electricity that a home needs, the home can either pull extra electricity from the battery or pull electricity from the grid. In some cases, the home can even charge the battery with grid power when it would be beneficial to do so, such as taking advantage of Time Of Use rates.
- Off-grid: A home that is not connected to the public electric grid, so all power needs must be met through solar panels, batteries, and other sources of self-generated power.
Why You Should Invest in Solar Panels
There are five main reasons why you should consider installing home solar panels:
- Provides clean, renewable energy: Solar energy produces no pollution, and the sun’s power does not harm the environment.
- Personal freedom and control over electricity: When you produce your own electricity, you have more control over where your energy comes from, what you can do with it, and how much it costs. In addition, battery storage can help you avoid power outages and blackouts, which provides peace of mind during a storm.
- Savings on your electric bill: Because your solar panels generate much of the electricity your home consumes, you could reduce your utility bills.
- Tax incentives: The federal solar tax credit can help you with the upfront costs of the installation, and some states have similar solar incentives.
- Proven technology: Current solar panel technology will continue generating electricity for 25 years or more, and solar panels are built to withstand extreme weather conditions.

Watch our 3-step “Timeline to Solar Savings” video to learn more:
Q: What is net metering?
A: Net metering is a solar incentive program where you can earn bill credits from your utility company if your solar panels produce more electricity than you use in your home, and feed that extra electricity back into the grid. You can then use those bill credits to cover the future cost of electricity you use from the grid.
Q: Is there any maintenance required?
A: Solar panels require very little maintenance, as they are made of durable materials like tempered glass and aluminum, and have no moving parts. Most solar panel manufacturers include solar warranties of up to 25 years. However, panels do occasionally require service or maintenance to keep them operating at peak efficiency, as outlined in our Solar Power Maintenance and Service Guide.
