Why do solar panels need cleaning?

It is essential to think about what can gather on them. The dust from construction nearby, bird droppings that won’t wash away with water, and leaves stuck in corners are all possible causes of dust in your home.

Don’t forget about pollen from local plants or smog if you’re in a polluted area. All these things can cover your solar panels and make it hard to catch sunlight properly.

When your panels are dirty, they can’t do their job well. They can’t catch as much sunlight, so they can’t produce as much electricity for your home. That makes your solar panel system less efficient and costs more money in the long run.

But it’s not just about efficiency. Dirt and grime can also wear out solar panels. That means you might have to fix or replace them sooner than you’d like, which can be expensive.

So, how often should you clean solar panels? Keep your solar panels clean to get the most out of them. It helps them work better and last longer, saving you money.
