The average 6-kW residential solar panel installation is $17,852 before incentives. Learn about cost factors, financing options, tax breaks and more.
Uses local climate data, your roof measurements, current local electric rates and current solar system cost to generate an accurate solar cost and savings estimate, customized for your home.
Solar panels cost about $30,500 on average—but often pay for themselves several times over through 25-30 years of electricity savings. Why trust EnergySage? If you''ve been putting off
Market analysts routinely monitor and report the average cost of PV systems and components, but more detail is needed to understand the impact of recent and future technology developments on cost.
Solar photovoltaic module prices refer to the cost of the solar panel itself, and do not include installation or other system components. Prices are compiled from three sources: Nemet
Historic Low Pricing: Solar costs have reached unprecedented lows in 2025, with systems ranging from $2.50-$3.50 per watt installed, making the technology more accessible than ever before.
Solar panel costs range from $16,600 to $20,500 for the average 6.5 kW system, but prices can vary from as little as $7,700 for smaller solar systems to upward of $34,700 for larger systems.
Meanwhile, costs declined for CSP (-46%), geothermal (-16%), and hydropower (-2%). Renewables continue to prove themselves as the most cost-competitive source of new electricity generation.
