Residential Solar Panel (400W)
A slice of captured starlight on your roof/Technology
A standard residential solar panel produces about 400 watts of peak power from a surface area of about 1.92 square meters. Modern panels convert roughly 21% of incoming sunlight to electricity. A typical home installation of 20 panels generates enough electricity for an average US household. The panels are mostly silicon, the second most abundant element in Earth's crust.
