Over time, the panels can become riddled with various outdoor elements, such as dust, dirt, pollen, sap, animal droppings, and more. This will essentially coat the panels with grime and prevent sunlight from fully penetrating them, resulting in a loss of energy absorption.

In fact, according to reports, dirty solar panels can decrease energy absorption by up to 10% or more in some cases.

Frequently cleaning your panels provides various benefits. Continue reading to learn more about why maintaining clean solar panels is ideal.

How Often Should I Clean My Solar Panels?

Solar Panel cleaning intervals will mostly depend on the environment.

For instance, panels installed in areas with high dust levels, such as in rural areas, near areas of high traffic, or in areas with lots of air pollution will require more frequent cleanings because they will accumulate dirt faster than panels installed in low dust areas.

This is also true for solar panels installed near the sea because they can collect salt build-up, which can cause erosion.

The angle of your panels can also affect how often they will get dirty. For instance, flat-mounted panels can allow rainwater to pool at the lower edge, which enables debris to gather there. They need to be cleaned more often than vertical panels where most debris is more likely to roll off with the rain.

On average, you should have your panels cleaned at least once every six months to every year to maintain maximum performance.

In the meantime, should you notice a drop in energy output, it could be an indicator that your panels need to be cleaned.
