How much does solar power cost in 2025?

Take control of your energy costs with solar power. Solar panels generate “free” electricity, but installing a system still costs money. A typical American household needs a 10-kilowatt (kW) system to adequately power their home, which costs $28,241 in 2025.

How much does a solar system cost?

If you just need a few panels for a small do-it-yourself solar project, expect to pay around $200 to $350 per panel (between $0.80 and $1.40 per watt). Note: The table below doesn’t include the cost of a solar storage battery, which can add anywhere from $7,000 to $18,000 to your total solar system costs.

How much does solar cost per kilowatt-hour?

The best way to measure such costs is called the levelized cost of electricity, which is essentially the lifetime cost per unit of electricity generated. The global weighted average LCOE stabilized at $0.043 per kilowatt-hour for utility-scale solar PV. This made solar 41% cheaper than the least-cost fossil fuel option.

How much does a solar system save on energy costs?

On average, homeowners with a complete solar system save $41,000 to $62,000 on total avoided energy costs over 25 years. It all depends on what your local utility charges for electricity, according to Robert Flores, a solar expert at The University of California, Irvine’s Clean Energy Institute.

How much does a 6kW Solar System cost?

The installation cost for a 6kW solar system ranges between $15,000 and $25,000, on top of panel costs. In 2018, solar panel pricing per watt dropped by 5%. With these savings and available incentives and financing options, solar has become an even more viable option for homeowners throughout the U.S.

How much does solar cost per watt?

We often reference the cost-per-watt ($/W) of solar to compare the value of a quote against the national average. According to the most recent data from the EnergySage Marketplace, the average cost-per-watt across the U.S. is around $2.53/W before incentives.
