Solar panel maintenance: what and how often?

Solar panels last for decades and need little attention. Still, there is a difference between low-maintenance and maintenance-free. A system that is never checked quietly delivers less after a few years than it could.

1. What you can follow yourself

With a monitoring system you see daily what your installation is doing. Compare this month's yield with the same month last year; a structural drop is the first signal. With Enphase you see it per panel, so a problem can be traced immediately to one spot on the roof.

2. What we check

During a service we check that the system works correctly: the mounting and ballast, the cabling and connectors, the inverter and the earthing. Where necessary we clean the panels. Dirt, moss and grime cost yield, certainly on a low-pitched roof where rain rinses less effectively.

• Compare monthly yields year on year
• Check mounting, cabling and inverter
• Dirt and moss cost yield
• Combine it with the heat pump service

3. How often is sensible?

For an average household a check every few years is enough, unless the monitoring shows something sooner. For a commercial roof or a flat-roof system with many trees nearby we advise looking more often. Feel free to combine it with your heat pump service, since the engineer is with you anyway.
