To generate electricity, your solar panels must be exposed to the sun. However, if you don't live in an area where there is a lot of smoke, dust, dirt, or wind, cleaning a solar panel is usually not necessary. In most cases, intermittent rainfall will be enough to keep solar panels naturally and safely clean and free from residue that reduces production.
If you live in an area with heavy particles in the air, it may be a good idea to update your panel every now and then. Below are answers to some important questions from owners of solar panel systems on how to clean solar panels and do it safely.
How to Clean Solar Panels
The most important thing to keep in mind when cleaning solar panels is that scratching or damaging the glass will reduce the energy output of the panel. It is a good idea to resort to panel cleaning when cleaning your car. Soap and lukewarm water with a soft sponge or cloth is the safest and easiest way to clean. Using a compress to remove dirty water can also help. Remember that it is not always possible not to damage or scratch the glass!
Is It Worth Paying for a Solar Panel Cleaning Service?
There are professional options for cleaning your solar panels, like going to the car wash, which your solar installer can do for you for a fee. If you have a system on your roof, it may be a good idea to contact a cleaning service if it's just for safety reasons.
Cleaning services may not do the job differently or better than yours, but they are equipped to reliably clean and maintain foundations. If you can reliably and effectively clean your panel with a hose, dish soap, and a soft cloth, it may not come down to the cost of servicing the grounding devices.
Does Your Solar Lease Cover Panel Maintenance?
In general, solar rental contracts include certain maintenance rules. Some companies regularly perform repairs on their panels, while others repair damage in customer reports. Keep in mind that solar panels are low maintenance and just spraying your panels with a hose every now and then can do the trick.
Should You Remove Snow From Your Solar Panels?
It is usually not necessary to remove the snow from the solar panels as they slide on their own. Most panel installations are wrapped at an angle and slide naturally when the snow melts. If there is no snow left on your panel, you can also invest in tools such as the snow cover on the solar panel, which will make it easier to safely remove the snow cover on the solar panels.
It is important not to use a broom, shovel, or another standard non-specialized tool to remove snow from the panels, as they can scratch the panel window and reduce power.
