Modern solar panels are specifically engineered to be highly water-resistant, meaning the panels themselves are rarely the source of a leak. Installation requires making penetrations into. Even a panel with several cracks can still operate without any loss of efficiency. However, just because it still works, it doesn't mean you can leave it be. This article explains common causes, signs to watch for, inspection best practices, repair choices, and preventative measures to protect roofing integrity while maximizing solar benefits. Water intrusion around solar arrays can damage decks, insulation, and electrical components, potentially creating safety risks and costly damage. But don't worry—you're not alone, and this issue is more common than you might think.
