Solar Panel Cleaning

Solar panel cleaning is an integral part of any maintenance process, especially for machines and devices that are exposed to external factors such as weather, changing temperature, dust, leaves, and pollution.  

Solar panels are a great example where regular and proper cleaning is required to ensure their maximum efficiency and long term use.

Geographical location and surrounding elements are the two biggest factors that pollute and affect the system.

While heavy rain may help clear your solar panels from debris and other pollutants, it still cannot replace the proper way of cleaning your solar system.

Why Clean Your Solar Panels?

Solar panels work by converting sunlight into electricity. If dirt, leaves, animal droppings or debris lands on its surface, its efficiency will be affected. When dust, sand or any small particle accumulates and covers the surface of a solar panel, the solar panel will have a hard time absorbing the maximum amount of sunlight it can harvest, which will lead to reduced energy production. This is why it is crucial to find a way to keep the panels free or at least minimize  exposure from any of these sediments/outside factors.

In addition, if there are trees or anything that may cover some portion of a solar panel, expect to see a drop or a lower than the average output from the panel. This is because the shaded area of the solar panel cannot receive as much sunlight as its exposed parts. The solution to this is quite straightforward. Make sure to place your panels away from trees or tall structures that may cover the panels. And if done by professional installers, this should not be a problem at all.

How Many Times Should You Clean Solar Panels?

The number of times in a year you need to clean your solar panels depends on where you live and how much dirt and debris accumulates on the panels over a period of time. In general, it is recommended to clean solar panels at least once a year. However, if you live in a place that is exposed to a lot of dust or pollution, you may have to clean your solar panels more than once a year.

Regular and proper solar panel cleaning ensures maximum efficiency of the solar panels and at the same time, it is one way of helping the device achieve its longest lifespan possible.
