Listen Up: The Solar Maintenance Myth

Save on your hotel -

Why are rooftop solar systems so reliable? First, because the solar panels themselves have zero moving parts, use tempered glass and anodized aluminum (better than most windows and skylights), and are covered by a 25 year manufacturer’s warranty. Second, because top quality microinverters carry a 25 year warranty and string inverters carry a 10 year warranty — and based on industry experience, the real-world performance of quality inverters has exceeded their warranty term. And third, because flashed rooftop mounting systems using all aluminum and stainless steel components will last at least as long as a homeowner’s roof.
