How well do solar modules work in inclement weather?
In cloudy weather, solar modules work, although they produce less electricity than on a sunny day. Under a light overcast, the modules might produce about half as much as under full sun, ranging down to as little as five to ten percent under a dark overcast day. If the modules become covered with snow, they stop producing power, but snow generally melts quickly when the sun strikes the modules; if you brush the snow off, they resume operation immediately. Our modules can withstand one inch (2.5 cm) hailstones at 50 mph (80.5 kph).
