Key insights and solar panel maintenance FAQs
Ultimately, solar panel maintenance is very minimal for most homeowners, though regular cleanings and inspections are recommended to ensure optimal system performance. Before you go solar, it is vital to understand what inspections, repairs, or part replacements are covered by the warranties included with your system from both equipment manufacturers and your installer.
How often should solar panels be cleaned?
The frequency recommended for solar panel cleaning depends on the environment surrounding your installation. In general, it's recommended to clean your panels at least once or twice a year. If you live in a dusty or heavily polluted area, you may need to clean your panels more frequently. While uncleaned panels will still work, dust and soiling (like on a car windshield) will lead to lower production output.
Does rain clean solar panels?
While rain can help to wash away some dust and loose dirt, it is not the most effective method for thorough solar panel cleaning. As such, relying solely on rain to clean your solar panels is not recommended for optimal production, but can extend the interval period between washing. Instead, regular cleaning, whether DIY or through professional services, can ensure your panels can operate at maximum efficiency.
Can severe weather and hail damage solar panels?
Hailstorms, high winds, heavy snowfall, and extreme temperatures can all potentially cause physical damage to your system, including micro-cracks in solar cells and loosened mounting materials. While most solar panels are designed to withstand the elements, and severe damage is rare, it's a good idea to inspect your system for any signs of damage or decreased performance after a particularly severe weather event.
