PVWatts

PVWatts is a tool developed by the U.S. National Renewable Energy Laboratory that estimates how much electricity a solar panel system can produce in a specific location. By entering details like your address, roof size, and the type of solar panels, PVWatts calculates the expected energy output and potential savings on your electricity bill. It considers factors such as sunlight, weather patterns, and system efficiency, providing a realistic projection of a solar installation’s performance. This helps homeowners and businesses evaluate the benefits and feasibility of adopting solar energy.
