SOLAR CLEANING

Why Do Solar Panels Need Cleaning?

  • Environmental factors such as dust, grime, bird droppings, oily stains and lichens may reduce the efficiency of the photovoltaic (PV) system and offsets your solar investment gains

“Our results show that the mean of the daily energy loss along a year caused by dust deposited on the surface of the PV module is around 4.4%. In long periods without rain, daily energy losses can be higher than 20%.” (Research by World Renewable Energy Congress, Sweden)

  • Having the solar panels cleaned regularly ensures sufficient sunlight to reach the photovoltaic cells and improves the solar system efficiency, decreasing your power bills and shortening the investment payback period.
  • Panels being inspected and cleaned once every six months is recommended.

Why Can’t the Rain Clean My Panels ?

Just consider what happens if you don’t clean your car’s windshield for six months. Dirt and dust will “go green,” completely blocking your view (and light) from entering your car. Think about how dirty your car/windshield will get in a few weeks. And on a rainy morning, remember that your car (if left outside) looks dirtier than before, as if dust and dirt had been moved. In fact, rainwater contains dust particles that stick to the surface when it evaporates. When we use a windshield wiper, we clean the center of the screen, but there’s a nasty layer of dirt where the wiper can’t reach. Your solar panel is in the same condition as the edge of your windshield. The wipers won’t get there, and it could be worse because most solar panels are angled less than your windshield. In addition, the smallest amount of loose dust moving in the rain can cause dust to pile up under each solar panel, which can lead to significant heating. In a string of photovoltaic cells on a solar panel, if one cell is shaded, the other cells will force an electric current through it, which will warm the battery and cause your solar output to be significantly reduced, greatly shortening the life of your panel.

Why Can’t I Clean the Panels Myself?

Safety Concerns

  • It is necessary to have a thoroughly inspection on panels for damage, cracks and loose connections before cleaning. Damaged panels can lead to a lethal shock hazard because of the leakage currents.
  • Cleaning the panels requires working at height. Only professionals who are well-trained and well-equipped can minimize the working hazards.

Effectiveness Concerns

  • Tap water and unqualified domestic detergent cannot thoroughly clean the panels and may leave a residue which diminishes the effectiveness of panel cleaning.
  • Environmental factors such as dust, grime, bird droppings, oily stains and lichens may reduce the efficiency of the photovoltaic (PV) system and offsets your solar investment gains
