1. Use special cleaning fluid to clean the panel. Ordinary tap water or well water cannot be used to wash and clean the panels, because the water contains many impurities that will adhere to the surface glass panels of the battery components and reduce the solar power generation efficiency.
2. When cleaning photovoltaic panels, you can wipe them hard with a wiper while flushing with water to remove them. The cleaning time in winter is set at 9:00 a.m. every day when there is sufficient sunshine, and the cleaning end time is determined according to the outdoor temperature to prevent freezing due to low temperatures and accumulation of dirt.
3. When cleaning photovoltaic panels, do not step on the panels, do not use metal or other hard objects to scratch hard-to-remove dirt, and do not spray cold water on the panels when they are very hot. If there are oil stains and other difficult-to-clean areas on the surface, use the above method to clean, and then use cleaning fluid or industrial alcohol to wipe the local area to achieve the cleaning effect.
