Solar Panel Cleaning

Do I need to clean solar panels?

The simple answer is yes, but not necessarily often. However, it is recommended that the solar panels be cleaned regularly to maintain optimal operation and performance. It should be noted that the frequency of solar panel cleaning depends entirely on the environment and the time of year. If you live in an area that gets less rain, your solar panels will need to be cleaned more often than in an area that gets a lot of rain.
You might be one of those people who's been doing this research about solar energy and have a
system for your home.
Take advantage of these benefits now, because your electricity bills will drop drastically. You tell your friends that switching to photovoltaics is a great investment and that not only does it have a positive effect on the environment, but it also significantly reduces your electricity bill.
But maybe not. They are not so aware of the maintenance required to optimize the solar energy absorption system. There are reasons why cleaning your solar panels is extremely beneficial for anyone with a system.
Are dirty solar panels less efficient?
Yes, dirty solar panels are less efficient than clean ones. Dust, bird droppings and leaves make it difficult for solar panels to function optimally. Panel performance ratings are based on maximum performance of panels affected by general contamination. Although SunPower systems have the highest efficiency on the market, even these modules can be damaged by the accumulation of dust or dirt.

How Much is the Output Loss Due to Dirty Solar Panels?

The most important thing is to keep your SunPower system running at peak performance. Solar production can drop by 1.5% to 6% per year due to the accumulation of dust or other particles. This is a very conservative number as the same study found that in the dustiest or most polluted areas, numbers can range from 2% to 50% for conventional solar panels.

How Dirt & Pollution Can Damage Solar Cells

Dirt and contaminants in the air not only affect the production of your solar panels, but also damage the solar cells themselves. A normal shaded cell from dust accumulation acts as a resistance to the energy generated by other cells, which in turn causes the shaded cell heats up and becomes damaged.
Many solar systems are not self-contained with a microinverter connected and rely on surrounding cells to maintain solar energy efficiency. However, the SunPower
cells are independently connected to the microinverter and cells around each other do not affect each other. If one cell has been shadowed or covered with dust, the others continue to function without damaging the shadowed cell.
But dust will still affect the performance of this cell.
