How Much Does Solar Cost?

Use the calculator to see how much you could save!

Your location, energy needs and equipment selection are the top three factors that contribute to solar panel cost.

Two significant location-based factors will determine your total cost and savings of going solar: the cost of energy where you live and how much sunlight you receive.

In states where traditional energy is more expensive, like California, Hawaii and New York, you stand to save more on energy bills when you switch to solar.

However, how much sunlight you receive also plays an important role in determining how many solar panels you’ll need (and thus how much you’ll pay for your system). If you live in a super sunny state like Arizona or New Mexico, you’ll have more daily peak sunlight hours, requiring fewer panels to meet your energy needs.

That’s not to say solar isn’t worth it if you don’t live in a state with high energy costs and abundant sunlight. See how energy costs compare in your state using the map below, and learn more about how you can determine how many solar panels you need.

The typical U.S. household uses 10,632 kilowatt-hours (kWh) of electricity each year or around 886 kWh monthly. However, several factors can affect your energy needs, including the size of your home, how many people are in your household and if you have an electric vehicle (EV).

The higher your household’s energy consumption, the larger the solar panel system necessary to offset your usage. For example, based on our average cost of a solar panel at $3 per watt with installation, a 6 kW system would run you around $18,000, while a 12 kW system would double the cost.

Solar providers typically want to install a system that generates just enough electricity to support your typical energy usage — so your panels aren’t producing too much or too little energy. When designing your solar system, you’ll typically speak with a solar expert to determine your current and future needs and decide what size system is right for you.

The cost of your solar system is directly proportional to its size. The more solar panels you install, the more expensive your system will be.

The ideal system size for your home depends on personal factors like your roof size and angle, energy usage and location. Ultimately, solar system size depends on your household’s energy consumption and how much energy you want to generate with your panels.

The most cost-effective option when purchasing solar panels is paying in cash upfront. With a cash purchase, you will own your system and not pay interest on a loan.

However, because solar systems are expensive, paying in cash is not an option for most homeowners. The next best option is to put some money down and finance your panels. Although you will pay interest over the loan period, you will still own your panels and benefit from energy savings. The more money you put down, the less interest you will pay over time.

Or, you can lease your solar panels. Instead of owning your panels, you will pay your solar company a fixed monthly rate to “rent” your system. You may see some energy savings with a lease, but you likely won’t save as much as other financing options. You also won’t be eligible for incentives like the 30% federal tax credit and will likely become locked into a lengthy solar lease contract.

The cost of your panels and equipment is by far the largest expense you’ll pay during your solar installation. There are many solar panel options available, and the manufacturer, installer and type of panels you choose will affect the final cost of your system.

There are three common types of solar panels: thin-film, monocrystalline and polycrystalline. Beyond those options, each solar panel manufacturer offers a selection of products with different wattages, durability and technologies that affect energy production and overall cost.

Your solar installer will walk you through choosing the right kind of panel for your home. However, it doesn’t hurt to research the best solar panel brands and manufacturers on your own.

Another factor that can greatly affect the ultimate cost of your solar system is the installation company that you choose. Use the chart below to help you find a provider with an installation cost within your budget and request a free quote.

Although the exact cost of your solar panel installation will vary depending on the company and type of panels you choose, you can expect your equipment (panels, inverters, batteries, racking or mounting hardware, etc.) to make up nearly half of your total cost.

Labor costs, administration fees, taxes, building permits and electrical permits comprise the rest of your expenses. Jesse Solomon, the co-founder of NCSolarNow, explained the cost breakdown of a typical solar panel installation as follows:

The demand to expand renewable energy infrastructure in the U.S. shows no signs of slowing. As a result, the federal government and many states are incentivizing residents to install solar panels on their homes.

There are plenty of programs that can help you save money on solar panels. Your solar installer can help you apply for the federal solar tax credit and any state and local incentives for which you’re eligible.

The Federal Solar Investment Tax Credit (ITC) is a tax incentive worth 30% of the total cost of your solar panel system. All U.S. homeowners who install solar panels are eligible for this credit, and it reduces what you owe in federal income taxes. For most solar systems, this credit is worth several thousand dollars, which is significant savings.

However, if you choose to lease your panels, you will not be eligible for this tax credit. You can only claim this tax credit if you own your panels.

The credit is currently set to decrease to 26% in 2033, then to 22% in 2034 before expiring entirely in 2035.

In addition to federal incentives, many states offer other incentives to go solar, including tax breaks, credits and rebates. If you’re interested in the solar incentives available in your state, you can browse the Database of State Incentives for Renewables & Efficiency (DSIRE) or visit your local government website to learn more.

Additionally, net metering is a program that allows you to sell the excess electricity your solar panels generate to your utility company for billing credits. Forty-one states and Washington D.C. have a state-mandated net metering policy, though some policies are better than others. States without a mandated net metering policy, like Texas and Idaho, may have utility companies that offer the program.

Many states also offer solar rebate programs for low- and moderate-income households or community solar programs that aim to make clean energy more accessible.

Installing efficient panels and maintaining basic system upkeep can help maximize your solar panel output, helping you save more money in the long run.

Efficient solar panels maximize your system’s energy production while requiring fewer solar panels and less roof space. SunPower currently offers some of the most efficient solar panels on the market, at 22.8% efficiency.

Most solar installers offer a solar monitoring app that allows you to easily see when your panels are underperforming. Keeping tabs on your system’s energy production helps you identify and resolve issues quickly.

Routine cleaning helps keep your panels running efficiently. Depending on the climate and conditions where you live, you will need to clean your solar panels once or twice a year. You should also clear out any debris caught underneath your panels. Additionally, trimming trees that are casting shade onto your panels can maximize your system’s productivity.

Although going solar is a large upfront cost, solar panels are usually worth it because you won’t be paying energy bills over the 25+ year lifespan of your system. If your solar panels are offsetting most or all of your energy consumption, you will recoup the cost of your system through energy savings long before your panels stop working.

So, in what situation might solar panels not be worth it? If your payback period is longer than the lifespan of your solar panel system, you will not be saving money in the long run. However, it’s very uncommon for that to be the case, especially considering the drastic decrease in the cost of solar over the past decade.

According to our research, the average payback period for a solar panel system in the U.S. is 8.5 years, compared to the typical lifespan of a solar panel system of at least 25 years.

The National Renewable Energy Laboratory estimates that solar payback periods are even shorter than that, at just four years for a standard monocrystalline solar panel system. So if your solar panels generate energy for 25 years, you’d be enjoying 21 years of free, clean energy after you break even.

If you’re tired of paying a high electric bill to your local utility every month, solar may be a good option to go green and save money over the lifetime of your panels. Ultimately, how much you can save with solar depends on where you live, what panels you choose and your energy usage.

We strongly recommend speaking with a solar professional about your unique solar needs to determine if solar is viable for you.

Yes, solar can increase the value of your house by improving your home’s energy savings and boosting appeal if you want to sell. Reports by Zillow and the U.S. Department of Energy’s Berkeley Lab concluded that the majority of home buyers are willing to pay more for a home with solar.

Although the amount of energy a household uses will influence how many solar panels it needs, it will likely cost around $20,000 to install solar panels on a 2,000-square-foot home.

Monocrystalline solar panels, which are most common for residential solar installations, typically last between 25 and 40 years, with most solar companies offering a 25-year panel warranty.

The cost of solar consistently trended down over the past decade, but ongoing supply chain disruptions and inflation from 2020 to 2022 caused solar prices to increase slightly. However, as these issues slowly resolve, the cost of solar is expected to continue trending down in 2023 and beyond. Plus, as traditional electricity rates climb, homeowners stand to save more by switching to renewable energy.

In most cases, solar panels are worth it for your home. Many homeowners save thousands of dollars in energy bills over the lifespan of their solar panels, plus you are generating clean energy to power your home.

A 6 kW solar system can save homeowners an average of $1,346 each year on energy bills, or around $112 monthly. Exact savings will vary depending on your system, location and local electricity rates.
