They're usually about 2 metres long and 1 metre wide, and they have a thickness of 3-5cm. The largest residential solar panels are as big as 3.1 square metres. Companies like Risen Energy produce panels this size that can generate up to 670W – around twice as much as a typical panel – which makes sense considering its size.

How much energy does a solar panel generate?

Solar panels are made up of cells, and the number of cells in a panel determines its size and how much energy it generates. A 60-cell monocrystalline panel can generate 325W to 335W and measures 1665mm long x 1006mm wide x 35mm high. A 72-cell monocrystalline panel can generate 385W to 400W and measures 1986mm long x 1006mm wide x 40mm high.
