Before you embark on the quest of cleaning your solar panel, there are some basic things you need to know, like its components and what materials it react with. Majority of solar panels utilize Silicon – Si mainly, plus a few other Common elements (e.g Aluminum, Boron, Oxygen, Phosphorus, etc).
#1 Make sure you contact your solar panel installer/company or read the manual guide to verify if your solar panel can be cleaned without any side effect (this is because solar panel components are different from others) and they might have certain recommendations guiding the cleaning of the panel.
#2 Can you reach the solar panel safely? Stay there and clean for hours without hurting yourself? If you can’t reach the solar panel (on the roof) it is safer to contact a professional who has the perfect tool for the system.[et_bloom_inline optin_id=optin_3]
