Monocrystalline (Mono) Photovoltaic (PV) solar panels are extremely durable. They have been tested in high wind, hail and heavy rain and snow fall.
Our roof solar mount systems are tested under 70ft of water pressure and resistance and are mounting into your truss to avoid ANY leakage.
Solar panels are virtually maintenance free, the heat they create will generally clean themselves. (after a heavy snowfall you might want to brush (with a solar panel approved squeegee) some of the snow away - although most light snow will melt and slide off on it"™s own.
