Well, rain or storm should not bother solar panels, that is good quality solar panels, much.

A high quality solar panel should easily withstand rains for 25 years, and even longer.

Some of the components of the solar panel, especially the outer glass and the backsheet, are provided specifically to provide protection from rain and other natural elements.

While hailstorms could damage some type of solar panels, the likelihood is very rare in case high quality panels are opted for. Top solar panel manufacturers are pretty aware of the danger hailstorms present to their products and hence opt for a toughened glass surface for their panels. Usually, high quality panels are so designed to withstand even the direct impact of hail up to one-inch in diameter.

The qualifying term here is “high quality”. Manufacturers of high quality solar panels ensure that they purchase the best and the proven materials especially for the glass on top and the backsheet at the bottom. The backsheet especially is given little thought, but this layer can play a significant role in keeping the solar panels healthy and productive for 25 years.

Another specific parameter you should look for while choosing solar panels that can withstand rain and snow is the Ingress Protection factor for the module junction box. This factor determines how much the junction box is protected against water seeping into it during rains and from snow.

A low IP rating might now augur well for your panels during rains, flood and snow.

There are times that the snow may pile up on your roof and solar panels. If you need to remove the snow from your roof because you’re concerned about the weight and how long it will take to melt, you might want to hire a professional to remove it.
