Factors That Impact Solar Panel Cost
Factors like where you live and how much energy you use will influence the overall cost of your solar panel installation. According to our survey of 1,500 homeowners with solar, it typically costs between $15,000 and $20,000 to install a 10 kW solar power system. The Solar Energy Industries Association (SEIA) estimates that solar panels can cost around $25,000. Keep in mind that these figures do not include any solar incentives, like the 30% federal solar tax credit.
System Panels and Equipment
The type of solar panels you select and how many you need will significantly affect your system price. A smaller home that consumes less energy may only need a 5 kW system, while larger homes with higher energy needs may require closer to a 10 kW system. Solar installations are typically priced by capacity, so the more energy you need your panels to generate, the more you’ll pay for your system.
Home solar systems also require an inverter to convert solar energy into usable power. You can also add a solar battery to store energy outside sunlight hours. Most solar companies will design your solar system with these components included, but selecting specific inverters or batteries, such as a Tesla Powerwall, may increase your overall cost.
Tier 1 vs. Tier 2 Panels
Solar panel tiers are criteria set by the Bloomberg New Energy Finance Report. To be considered Tier 1, a manufacturer must have provided solar products to six different projects under specific financing guidelines within the last two years. Any manufacturer that does not meet this criteria is considered Tier 2.
These guidelines do not consider or measure a panel’s efficiency rate or durability. Instead, these labels refer to a solar manufacturer’s bankability and standing in the industry.
Premium vs. Value Panels
A value solar panel refers to a solar panel designed to last around 20 to 25 years. Value panels are typically backed by a 10- to 12-year warranty and feature high-quality, reliable materials. In short, these panels are great value for your money. You may find that most thin-film and polycrystalline solar panels are value panels.
On the other hand, premium panels feature higher-quality materials and have a lifespan of 25 to 40 years. These panels usually feature higher efficiency rates and lower temperature coefficients, with 25-year performance warranties. Premium panels tend to be manufactured by big-name companies confident in their quality, performance and durability. Most often, premium panels are monocrystalline solar panels.
How To Save Money on Solar Panels
You can save money on solar panels by taking advantage of solar incentives, comparing solar panel prices and quotes, and installing panels yourself (if you have the expertise and equipment).
Take Advantage of Solar Incentives
All U.S. residents are eligible for the 30% federal solar tax credit when they purchase residential solar panels. Additionally, many state governments and utility companies offer local incentives including net metering, solar rebates and tax exemptions that can further reduce your cost. Use the dropdown below to discover the incentives offered in your state.
Compare Quotes from Installation Companies
Get several quotes from local solar companies and compare costs between providers. Although solar panel installation costs vary vastly by project, our 2023 poll of 1,500 homeowners with solar found that Palmetto Solar and Sunrun tend to be on the lower cost end of solar providers.

Install Panels Yourself
Installing solar equipment requires electrical expertise, specialized equipment and special permitting that make it difficult to install panels yourself. Not to mention, DIY installation poses risks due to the height of your roof and electric wiring. Additionally, since the majority of your cost comes from equipment, your savings when installing panels yourself may not be as much as you think.
According to Jesse Solomon, the co-founder of NCSolarNow, installation and labor costs only make up about 12% of the total cost of your solar system. In most cases, you’re better off going with a professional. Plus, your solar installer will help you apply for solar incentives you’re eligible for, which helps maximize your savings.
Solar Financing Options
A variety of financing options can make solar power more accessible, with options that include a cash purchase, solar loan, solar lease and power purchase agreement (PPA). Each payment model has its own set of pros and cons. We recommend purchasing your system in cash for maximum savings, but if you wish to avoid a large upfront payment, a solar loan is the second best option, followed by solar leases and power purchase agreements.
Cash Purchase
A cash purchase is when the customer pays the entire cost of the system upfront. With a cash purchase, you have immediate ownership of the system and can claim solar incentives to lower your return on investment. However, since most solar systems cost $15,000 to $20,000 on average, a cash purchase may not be realistic for everyone.
Solar Loan
As the name suggests, a solar loan allows homeowners to purchase a system by borrowing money from a lending agency, such as a bank. Solar loans combine the benefits of both cash purchase and solar leases — homeowners own the system and become eligible for incentives, while also having a comfortable payment structure.
Solar Leasing
A solar lease allows customers to rent a solar system to use on their property instead of purchasing the panels outright. With a lease, homeowners typically pay an agreed monthly amount to the installer in exchange for the energy generated by the system. Leases never result in system ownership, which means you cannot claim certain solar incentives like the federal solar tax credit.
Power Purchase Agreement (PPA)
A power purchase agreement is a contract between an installer and a customer in which the customer pays a fixed amount for every unit of energy used, similar to traditional grid power consumption. While often confused with a solar lease, PPA payments vary based on a system’s energy generation, offering a more balanced solution to the homeowner.
Benefits of Solar Energy
Solar energy offers various benefits to homeowners, including lower utility bills, increased home value and a lower environmental impact.
Lower Utility Bills
The typical household in the U.S. spends about $1,500 per year on electricity, according to the Energy Information Administration. Solar photovoltaic (PV) panels can provide long-term savings by lowering your reliance on grid power and offsetting electricity costs with renewable energy.
While the upfront cost of solar panels can be hefty — about $15,000 to $20,000 on average — incentives like the federal solar credit, net metering programs and state tax breaks can help offset the price. Although you will see the most immediate savings by purchasing your system in cash, many installers offer solar loans, leases and power purchase agreements (PPA) so you can finance your system over time.
Here are some of the most significant factors that influence the actual savings you receive from a solar system:
- The incentive programs in your state
- The amount of electricity your household consumes
- The size of your solar panel system
- How you pay for your system (you cannot claim federal and state tax credits with leases and PPAs)
- Direct hours of daily sunlight
- Size and angle of roof
A solar professional can survey your home and give you an estimate of how much you can save when you switch to solar.
Increased Home Value
A solar energy system can increase your overall property value. According to a study by Lawrence Berkeley National Laboratory, solar panels increased the value of a home by an average of $15,000. A Zillow study reported that homebuyers were willing to pay 4.1% more for a home with solar panels, an average of $9,274.
Lowered Environmental Impact
Each kilowatt-hour (kWh) of solar power generated reduces greenhouse gas emissions, such as carbon dioxide and other pollutants like sulfur oxides, nitrogen oxides and particulate matter. According to the National Renewable Energy Laboratory, you save 1,400 pounds of carbon dioxide emissions from traditional energy sources for every 1,000 kWh of clean electricity your solar panels generate.
Solar panels also reduce the water consumption needed by power plants to generate electricity.
