Solar panel cost in 2026: It may be lower than you think

Solar panels cost about $31,000 on average before incentives and most homeowners earn that back several times over through decades of electricity savings.

)

If you've been putting off solar because of sticker shock, this might change your mind: Most homeowners save $41,000 to $155,000 over 25 years. While your neighbors watch their utility bills climb year after year, your panels generate free electricity for decades.

The typical home requires about 12 kilowatts (kW) of solar energy to meet its electricity needs, which costs an average of $31,135 before incentives, according to EnergySage data. Depending on where you live, state and local programs can knock thousands off that price, and if you finance with a loan or sign a lease or power purchase agreement (PPA), you'll see immediate positive cash flow as long as your energy savings exceed your monthly payment.

Understanding solar costs means looking beyond sticker prices. Right now, systems average about $2.60 per watt before incentives. But this number varies depending on your location, roof characteristics, and the equipment you select. Your state's averages matter more than national numbers, and factors like shading, roof complexity, and local incentive programs all play a role in your final price.

Solar equipment costs

The panels themselves are probably the first thing that comes to mind when you think about going solar, but solar panels represent less than a third of the total solar equipment costs. You can expect all required solar equipment, including supply chain costs and sales tax, to cost about $14,011—about 46% of the total system price.

The type of panel you install also directly impacts the quality of your installation. Monocrystalline solar panels offer the highest efficiency and power output and are used in most home systems today. They're often more expensive than polycrystalline solar panels, but you need to buy more polycrystalline panels for the same amount of power, so your overall installation costs may be similar. Thin-film solar panels are the cheapest type of panel, but they aren’t often used for home installations due to their low production.

Costs Breakdown

Component Average cost* Percentage of total cost**
Solar panels $3,736 12%
Solar inverter(s) $3,114 10%
Racking equipment $934 3%
Electrical wiring $2,802 9%
Supply chain costs $2,802 9%
Sales tax $623 2%
Installation labor $2,179 7%
Sales & marketing $5,604 18%
Overhead costs $3,425 11%
Solar installer profit $3,425 11%
Permitting & interconnection $2,491 8%

Additional Costs

Solar panels require little to no maintenance over their lifetime, so you shouldn't expect to spend much once your panels are operating. The strongest warranties associated with your equipment and labor, the less you'll need to worry. The best solar panel brands today offer comprehensive 25-year warranties.

There’s always a chance that something happens that’s not covered by your warranties. You may need to trim trees as they grow or hire a cleaner if you live in an area with heavy air pollution or pollen. Learn more about potential costs you could run into post-installation.

Payment Options

How you pay for solar impacts your total cost and long-term savings. There are three main ways to pay for home solar:

How to Lower Costs

If you want to lower your upfront cost of solar, you can:

  1. Finance your solar panel system. Choose to finance your system with a solar loan or lease/PPA.
  2. Install a smaller system. This can lower your overall price.
  3. Choose less expensive equipment. Get high-quality equipment without paying a premium.
  4. Get multiple quotes. Comparing quotes can save you big.

Conclusion

Solar is worth it for most homeowners because it eliminates or significantly reduces your electric bill. It's essential to think of solar panels as an investment that typically pays for itself within a decade, leading to substantial savings over time.
