Here are the steps to clean your rooftop solar panels. Follow them and enjoy the power of the sun!
Some may argue that it is not necessary to shut off the system, but it’s better to be safe than sorry. Technically speaking, solar panels cannot be turned off. If they are exposed to sunlight, they will convert it into energy.
However, the safest course of action is to shut down the entire system, which entails isolating the panels for the time being. This will prevent even the minute chances of short circuit, eventually setting the house on fire- or worse yourself.
Please make sure you are safe when you go up the roof. It is a very important step in the process.
As you might already know that solar panels have a layer of glass protecting them from dirt, grime, scratches, etc. A hot sunny day may make the glass layer very hot to the point that a splash of colder water could crack them. Also, a scorching hot day is not very ideal as you will be on the roof, closer to the sun.
Gently scrub with a soft bristle brush to loosen up the dirt and spray it down with water. Do not use too much pressure while scrubbing; keep in mind that solar panels are sensitive. There are many types of brushes in the market dedicated to cleaning solar panels. Some have rotating heads with an integrated water supply channel, and some are plain brushes. You can choose any brush; just make sure they have soft bristles.
Not always, the cleaning process will require a cleaning agent. Depending on how dirty your panels are, you can use them or skip entirely. In most cases, only the brush and water seem sufficient, but in some cases, a cleaning agent is required.
It is advised by professionals to use a very mild and diluted cleaning agent like dish soap diluted in water. But you can use special glass cleaners that are formulated to clean the solar panels.
You can also use white vinegar to clean the panels but water it down beforehand. With every 100ml of clean water, use no more than 5ml of vinegar. This natural substance contains acetic acid, which is powerful enough to dissolve tenacious muck without damaging your solar panels.
After you are done using the cleaning agent, thoroughly rinse it down with clean water once again.
Lastly, you will need to get rid of the water on the surface of the panels. To do that, use a good quality squeegee. This step is important because if you let the water dry on the surface, there would be water marks all over the panel, eventually dragging down the efficiency of your solar array. Yes, watermarks can affect your panel’s efficiency rate.
And that is how it is done!
Follow these simple steps for a clean and efficient solar array and enjoy your solar panels to their fullest. If you have frequent rain and less pollution in your area, your solar array might not get that dirty and hence require less cleaning. However, a comparatively drier area will have more dust. So, if you clean your panels in that case, you will reap a higher benefit for your investment which is your solar panels.
