Note: Costs are expressed in constant 2024 US$ per watt. Global estimates are used before 2010; European market benchmarks thereafter due to limited data availability. Solar photovoltaic module prices refer to the cost of the solar panel itself, and do not include installation or other system components.
This evaluation determines the viability and potential output of a solar photovoltaic (PV) system, ensuring you get the best possible return on your investment. Both homeowners and contractors should start here. Your journey begins with your utility bills.
Solar panels generate “free” electricity, but installing a system still costs money. Financially, whether or not the investment in solar is worth it for you depends on how much you can save on your electricity bill. In the best-case scenario, it's easy to make the switch, and you're happy with the system's performance.
Another measure of the relative cost of solar energy is its price per kilowatt-hour (kWh). 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. Net cost of the system / lifetime output = cost per kilowatt hour
