Are solar panels waterproof?

Almost always, rooftop or ground-mounted solar arrays will have panels exposed to rainy, wet weather, meaning panels must be waterproof to keep producing power for many years. Because solar panels have been exposed to the elements for several decades, they need to resist water damage as possible. All home solar panels are waterproof.

Are solar panels protected against rainwater?

It seems like solar panels are protected against water, however, there is something else in your PV system that needs protection from rainwater, your roof.

Can photovoltaic panels collect rainwater?

Aside from harnessing the sun’s energy, photovoltaic (PV) panels can also provide an opportunity to collect rainwater. With water supplies becoming an increasing concern, more states in the U.S. are embracing rainwater harvesting as an effective means for water conservation.

What happens if a solar panel gets flooded?

A non-waterproof solar panel may get flooded with water, causing less sunlight to reach the solar cells or even breaking individual cells. If this happens, they will likely not produce the power needed to fulfill their production warranty promise, and your solar manufacturer will replace any water-damaged panels.

How to install solar panels on a roof?

In a rooftop PV array, the mounting system requires to penetrate the surface of the roof and the flashings (aluminum supports of the rails) need to be installed over rafters or trusses that will effectively resist the weight of the solar panels and the mounting system.

Do solar panels have a warranty?

Luckily, most solar panel manufacturers offer two different warranties to protect your solar panel investment: an equipment warranty and a production warranty. A solar panel equipment warranty protects against problems associated with the quality of the physical solar panel.
