How much do solar panels cost in 2023?

Consider solar panels if you live in a state with high energy costs

Key points:

• The average solar panel system in 2023 costs about $31,558 before factoring in tax credits and solar incentives.
• The Residential Clean Energy Credit offers 30 percent of the total cost of solar panels as a credit when you file your annual federal tax return.
• Solar panels could help you save more than $900 annually on energy bills.

Solar panels can be a great solution to rising energy bills or frustration over power outages in your area. An installed solar panel system generates electricity to power your home, meaning you wouldn’t need to pay as much for traditional electricity from the grid. While the cost of solar panels has dropped by more than 60 percent in the past decade, investing in solar is still a hefty investment. The total price will depend on the size of your system, solar components, installation costs and other factors. You can lower the cost through solar incentives and tax credits at the federal, state and local levels.

How much does solar cost?

The price of the system components isn’t the only factor impacting the total cost. You should also consider soft costs, including installation, taxes, inspection fees and more, all of which contribute to the total price.

The cost of solar panels is calculated by the price per watt. To estimate how much a system will cost, multiply the price per watt by the system size. The system size is determined by your energy consumption, typically over a 12-month period. Based on data from the Lawrence Berkeley National Laboratory, a Department of Energy Office of Science laboratory, the national average cost of solar in 2022 was $3.67 per watt for an 8.6 kW system (rounded up). That works out to the estimated average cost of an installed solar system in the U.S. being $31,558. 

It’s clear that solar panels aren’t cheap, but you can lower the installed cost through incentives, rebates and tax credits. The most important solar incentive to know about is the federal Residential Clean Energy Credit, which was formerly known as the Investment Tax Credit (ITC) and is part of the Inflation Reduction Act. Solar owners can claim 30 percent of the total cost of their solar system as a credit when they file their federal tax return. 

Here’s how the math works out for the average solar system:

Many states and local governments offer solar incentives, too. You can combine these with the federal tax credit to further lower the price of solar panels. 

According to SaveOnEnergy, the average monthly electricity bill in the U.S. in 2022 was $151, or about $1,812 annually. (SaveOnEnergy is also owned by Bankrate’s parent company, Red Ventures.) Depending on how you pay for your solar system, you may experience immediate savings. If you finance your solar panel system, you may not experience savings right away, but likely will in the coming years.

Financing your system through a solar loan may not provide instant savings because you’ll need to account for a monthly loan payment. Your loan payment is affected by your system size and annual energy consumption. As an example, the average system costs $22,091 after tax credits. If we assume a 6 percent interest rate over 20 years, your monthly loan payment will be around $158 per month.

You can use your energy bill to estimate how long it will take to experience a return on your solar investment. As an example, we’ll use U.S. averages:

• Average cost of an 8.6 kW solar system: $31,558
• Installed cost after factoring in the 30 percent tax credit: $22,091
• Annual energy bill: $1,812

$22,091 / $1,812 = 12.2 year payback period

The Energy Information Administration (EIA) anticipates a 2 to 3 percent increase in energy prices per year. As energy rates increase, the potential savings with solar may increase as well, reducing the payback period.

Breakdown of solar costs

The total cost of a solar system can be broken down into two categories: hardware costs and soft costs. 

Hardware costs include the materials and components of the system, like solar panel modules, inverters and mounting equipment.

Soft costs include installation expenses, permits and administrative fees. Soft costs make up approximately 65 percent of the total cost of a solar system, according to the Solar Energy Industries Administration (SEIA). 

Data from the National Renewable Energy Laboratory (NREL) breaks down typical costs associated with solar panel installation:

• Equipment: This is all of the hardware you need in a solar system, including solar panels, inverters and mounting equipment. Hardware prices will vary by components, specifications and manufacturers. Equipment makes up 35 percent of the cost of a solar system.

• Installation and labor: Solar installers charge for the labor and installation of solar panels. You can expect several people on-site to complete the installation. Installation costs make up 19 percent of the cost of a solar system. 

• Overhead cost: Overhead includes the marketing, sales and administrative costs associated with running a solar installation company. You wouldn’t pay overhead costs directly, but they will be included in the overall cost for the installation. Overhead costs make up 11 percent of the cost of a solar system.

Financing solar panels

If you have the capital available, you can purchase your solar system outright. You won’t have to worry about interest rates or monthly payments. Because of the large expense, buying a solar system with cash is not always feasible. However, there are several financing options available depending on your needs.

• Personal loans: Personal loans have fixed interest rates and fixed monthly payments, making them a reliable and predictable option. You will still qualify for solar rebates and incentives if you finance with a personal loan.

• FHA, Fannie Mae and Freddie Mac loans: These mortgage loans help you finance your home and solar panels at once. An FHA 203(k) loan offers financing for the purchase of a home and remodeling and repairs, all rolled into a single loan. A Fannie Mae HomeStyle loan does the same, with both first mortgages and refinances. There’s also the CHOICERenovation mortgage from Freddie Mac, which offers loans to pay for renovations. These types of loans are often easier to qualify for, although they may also come with higher interest rates. These may be especially good options if you are purchasing or gut-renovating a home and want to install and finance solar panels at the same time.

• Home equity loan and home equity line of credit (HELOC): If you have a lot of equity in your home, a home equity loan or HELOC may be an option — letting you borrow against your ownership stake. A home equity loan normally comes with fixed interest rates and predictable monthly payments. HELOCs often come with variable interest rates, which could change over the lifetime of your loan. The interest you pay on these loans may be tax-deductible, helping you lower the amount you owe in taxes.

• Solar leases or power purchase agreements (PPAs): The installation company owns the system, but the electricity from the panels powers your home. The upfront cost is low and you only pay a monthly rate to lease the system, but you won’t qualify for most incentives or tax credits.

Is solar right for your home?

Before signing a contract with a solar company, it’s important to know whether solar panels will work well for your home and budget. A few things to consider include your current energy costs, incentives in your area that impact the price and how much sunlight your roof receives. 

Review your electric bill

The amount you pay in electric bills each month depends on electricity rates in your area and how much energy you use. The more energy you consume, the higher your bill will be. The same can also be said for electricity rates — higher rates will often equal a higher bill. There are some exceptions to this rule. Check your utility bills for an estimate of how much you’re currently paying and how much energy you normally use each month. 

Your energy consumption levels can help you estimate the size and cost of the solar system that would cover your energy needs. Depending on how much you normally pay for energy, solar may or may not be a logical choice. If your bills are normally low, investing in solar panels might not provide enough financial benefits. If you’re often charged high electricity bills, installing solar panels could make financial sense.

Learn about government incentives near you

Solar incentives and credits are readily available across the U.S. and can make the switch to solar more affordable. We’ve already discussed the 30 percent federal tax credit, which can lower the average cost to install a solar system by $9,467.

Another common solar program is net metering, which is offered in some form in almost every state. Net metering lets you return excess solar power generated by your system back to the power grid in exchange for credits on your electricity bills. To participate in net metering, solar owners need to remain tied to the grid. They can monitor their net metering credits to understand the financial savings that the program offers. Many states also have policies to exempt residents from additional sales or property taxes on solar panels. The Database of State Incentives for Renewables & Efficiency provides a complete list of solar incentives by state.

Evaluate your sunlight exposure

Solar panels will produce the most electricity when they receive a lot of sunlight. The general consensus is that solar panels are more efficient when they get at least four hours of direct sunlight every day.

Solar panels can still generate electricity in indirect sun, although it will be less than if they received direct sun. This applies to cloudy and rainy weather conditions as well. However, if your roof is shaded or you live in a particularly cloudy region of the U.S., solar panels might not be worth the price tag. 

Cost of solar panels by state

The average cost of solar panels varies by state. As we’ve outlined, the total cost will vary based on the individual system, but local factors impact it as well. Before factoring in tax incentives, the top five solar-producing states aren’t far off from one another in price per watt, though they do range in terms of system size.

How much do solar panels save?

Residential electricity rates have increased 10.7 percent across the U.S. since 2021, based on data from the EIA. Using a baseline of 1,000 kilowatt-hours (kWh) of usage, the national average monthly energy bill in 2022 was $151, or $1,812 annually. If you invest in a solar panel system that covers your entire energy usage, you could save more than $36,000 on energy bills over 20 years.

Solar panel manufacturers normally provide a 25- to 30-year warranty on the solar products. Given the average payback period is under 14 years, solar panels could help you save on energy costs for well over a decade after you’ve paid them off.

Estimating how much you could save with solar hinges on a few factors, including your energy consumption, typical electric bill and the size of a solar panel system. If you tend to use a high amount of energy each month, you would need a larger (and likely more expensive) solar system to completely cover your usage. If this were the case, your upfront cost would be higher, but so would your savings on energy bills. 

You should also consider how your financing choices will impact long-term savings. Residents who purchase a system with a solar loan or lease it will need to account for a monthly payment.

The most accurate way to determine how much money solar panels save is by getting a quote from a reputable installer.
