About How much does it cost to generate electricity with photovoltaic panels
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. That price effectively drops to $19,873 after considering the full federal solar tax credit.

6 FAQs about [How much does it cost to generate electricity with photovoltaic panels]
What is the cost of solar panels?
Solar panel cost payback calculator. Solar systems can cost anywhere from $5,000 to $20,000. This solar payback calculator includes the cost of solar panels, any potential rebates, and annual electricity savings. Based on this, we can determine how quickly the solar panels pay for themselves.
How much does it cost to install a solar panel?
Solar panels could reduce your bills and even earn money by generating electricity you can sell back to your energy company. But the average solar panel system of 3.5kWp will cost around £7,000 to install, according to estimates from the Energy Saving Trust.
How much does solar cost per watt?
Commercial solar costs average $1.83 per watt. The cost per square foot for residential solar panels is estimated to be between $4 and $10, though most estimates are based on the energy needed, at $2.53 to $3.15 per watt. Solar energy offers households and companies the ability to generate their own renewable electricity.
How much does a solar PV installation cost per kilowatt?
The mean average cost per kilowatt of a small solar PV installation (0-4kW) is above £2,000 for the first time since these records began in 2013/14. Prices for larger solar installations (4-10kW) increased even more dramatically - by 31% since 2021/22.
How much energy does a solar PV system generate a year?
Solar panel systems on homes are typically up to 4kWp. A system of this size can generate more than 3,000kWh per year. For comparison, a home using a 'medium' amount of electricity gets through 2,700kWh a year on average, according to energy regulator Ofgem. A 'high' user takes 4,100kWh a year. The cost of a solar PV system depends on:
How much does a solar system cost?
Efficiency improvements and declining costs have encouraged homeowners to install larger systems. While most systems range from 5 kW to 11 kW, today’s average residential solar system is 7.2 kW. Considering this size, the cost of solar panels will range from $21,600 to $36,000 before tax credits or other local incentives.
