Turn off the solar panel system; this will help ensure your safety and prevent damage to the equipment. Use a soft brush to clean the surface of dirty solar panels and remove any debris, such as dirt and dust. Yes, it's possible to be electrocuted when cleaning solar panels if you don't follow the proper methods to do so. It's a safety precaution that needs to be taken.
Turning off solar panels helps minimize the risk of electric shock if the connections get too wet. Solar panels cannot be used while they are being cleaned. If professional services are hired, they can work to cut off the electricity and do the cleaning, which reassures homeowners and gives them confidence that their system will not be affected by an electrical error. Clean solar panels will have lower energy costs because they allow for maximum exposure and greater solar production.
However, it is currently estimated that cleaning solar panels consumes around 10 billion gallons of water a year, enough to supply drinking water to up to 2 million people. Rain can remove much of the dirt and debris that could prevent a home's solar panels from absorbing the maximum amount of sunlight. Meanwhile, regular rain can remove dust and cause solar panels to continue to produce around 95% of their maximum capacity. Cleaning solar panels shouldn't cost too much, nor should it be too complicated a process.
It's important to remember that solar panels heat up in the middle of the day, so it's best to schedule the cleaning schedule at dawn, at dusk, or on a cloudy day when the surface is relatively cold. I suggest that you hire a professional solar panel cleaning expert to clean it properly. The scratches will cast small shadows on the photovoltaic cells located below the tempered glass layer, permanently exhausting the energy production of the solar panels. If cleaning solar panels seems more dangerous than beneficial, contacting a professional is a practical solution to improve solar production.
They should have information about the roof materials, the roof pitch, the square footage of your solar panel, and photographs or digital representations of how the solar panels are placed on the roof. Laboratory tests carried out by Panat and Varanasi showed that the decline in the energy production of the panels occurs abruptly at the beginning of the dust accumulation process and can easily be reduced by 30 percent after only one month without cleaning them. Especially in dry climates or near industrial or construction sites, relying on rain to keep panels clean may not be enough. Standard hardware supplies can be used for a solar panel cleaning project, but safety considerations are critical.
