Solar panels use photovoltaic cells to convert sunlight into direct-current electricity. An inverter converts that electricity into the form used by many building electrical systems.
The amount of energy a system produces depends on factors such as sunlight, panel orientation, shading, temperature, equipment, and system losses. A site assessment helps establish realistic expectations.
Before selecting a system, review your electricity use, roof or site conditions, utility rules, and whether you need battery backup. Ask for a proposal that explains its assumptions.
