How to Prevent Your Solar Panels From Cracking

It is rare to crack a solar panel in one single event (this is called ''thermal shock''). However, over time many cycles of thermal stress can cause solar panel glass to crack in a phenomenon called ''thermal fatigue.'' This thermal fatigue is a real threat to long-term panel performance and warranties. The best way to clean your solar
