Solar Panel Cleaning

To clean or not to clean? That is the question regarding solar panels.

Do I Need to Clean Solar Panels?
A simple answer is yes but not necessarily often. However, to maintain optimal function and efficiency – cleaning your solar panels on a regular basis is advised. It should be noted that the frequency you clean your solar panels is entirely dependent on your environment or time of year. Living in an area with less rain could mean you should clean your solar panels more often than someone who lives in an area with much rainfall.
Maybe you are one of those who have researched solar and own a system for your home. You are now enjoying the benefits of it as your electricity bill gets slashed to pieces. You tell your friends what a great investment it is to go solar and how it not only affects the environment positively but it reduces your electricity bill significantly. But maybe you aren’t as aware of the maintenance required to optimize your solar system absorption. There are reasons why cleaning solar panels is extremely beneficial for someone who owns a system.
Dirty solar panels are less efficient than clean ones. Dust, bird droppings, and leaves hinder the solar panels to operate at maximum efficiency.

The important thing is to maintain the optimal output of your SunPower system. There can be a decrease of 1.5% to 6% of solar output annually due to collected dust or other particles. This is a very conservative figure as studies showed that in dustier areas or places with higher pollution the numbers can range between 2% and 50% on conventional solar panels.

Not only will dirt and airborne pollutants affect the production of solar panels, but they will also harm the solar cells themselves. A conventional and regular cell shaded by dust gatherings will act as a resistance to the power generated by other cells and this, in turn, causes the shaded cell to heat up and damage cell.

Rain, however, is not the cure-all for cleaning solar panels because rain still contains within it “airborne dust particles” that will still leave a layer of dust on the panels. This means that although rain may wash out the old dust on the panels, it brings with it new dirty particles.

How Often Should You Clean Solar Panels?
It is generally recommended to clean solar panels every 6 months to a year in order to maintain the productivity, efficiency, and effectiveness of the panels. However, based on where you live and the level of dirt and pollution, the need for cleaning may be more frequent.
