Powering your home with solar panels starts with knowing the amount of sun exposure you can expect for your area. Each region in the US has different expectations for sun exposure. To capitalize on the benefits of solar energy, you need to hire someone experienced in the region you live in.
Calculating Solar Capture
The number of panels necessary to generate the solar energy your home needs depends on the expected weather, the roof angle, the roof composition, the age of the roof and the amount of expected usage. Each panel should ideally receive five hours of sunlight a day to generate electricity. Shaded panels prevent the sun from reaching them and generate less energy.
