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.

Can solar panels operate in the rain?

Solar panels can still operate in the rain, but their power output depends on cloud coverage. Heavy rain clouds will most likely hinder energy production, but rainfall provides a safe and easy way to clean solar panels. Rainfall can rinse solar panel surfaces, preventing layers of dirt and debris from forming and blocking future sunlight.

Does rain wash solar panels?

Rainfall can rinse solar panel surfaces, preventing layers of dirt and debris from forming and blocking future sunlight. Your solar power system may store less energy when it rains but it will clean your panel surfaces and relieve you of this maintenance task.

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.

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.

What is a good IP rating for solar panels?

The higher the number, the greater the protection. Some common IP ratings for solar panels are IP65 (protected against dust and low-pressure water jets), IP66 (protected against dust and high-pressure water jets), and IP67 (protected against dust and immersion in water up to 1 meter).
