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.
Numbers calculated by financial advisory Lazard as of June 2025 estimate price ranges for the generation of one MWh of energy by different sources.
These benchmarks help measure progress toward goals for reducing solar electricity costs and guide SETO research and development programs. Read more to find out how these cost benchmarks are
Solar panels can lower your electricity bill by 75% or more, but the upfront investment is significant. Most homeowners spend between $12,600 and $33,376 to install a complete residential
Whereas the price per watt considers the solar system''s size, the price per kWh shows the price of the solar system per unit of energy it produces over a given period of time.
Average price of solar modules, expressed in US dollars per watt, adjusted for inflation.
Depending on the local regulatory environment, some or all wholesale costs may be passed through to consumers. These are costs per unit of energy, typically represented as dollars/megawatt hour
Cost per watt ($/W) represents the upfront price of your solar system divided by its total wattage capacity. This metric is essential for comparing
Cost per watt ($/W) represents the upfront price of your solar system divided by its total wattage capacity. This metric is essential for comparing quotes from different installers, as it

While calculating costs, several internal cost factors have to be considered. Note the use of "costs," which is not the actual selling price, since this can be affected by a variety of factors such as subsidies and taxes: • Capital costs tend to be low for gas and oil power stations; moderate for onshore wind turbines and solar PV (photovoltaics); higher for coal plants and higher still for waste-to-energy, wave and tidal, solar thermal,
For hydropower, wind, solar, and geothermal technologies, no heat rate is reported because the power is generated without fuel combustion, and no set British thermal unit conversion factors exist. The
