Operating and Maintaining Your Home Solar System

If you have a rooftop solar system, you already know that it requires very little maintenance. But “low” maintenance doesn’t mean “no” maintenance. On this week’s show we’ll review the periodic cleanings and inspections your system needs — as well as some of the more extensive work that may be required every 10-15 years or so.

For many people, their goal is to achieve the maximum net electric bill savings while minimizing ongoing costs. Why spend $300 to wash rooftop solar panels twice a year if, due to regular rain, they get only slightly dirty with only a minimal energy output decline?

Nevertheless, there are a few things that all homeowners should check regularly. First, check your system monitoring regularly — or just check to see that the green light is illuminated on your inverter (a red light or no light usually indicates a failure). Second, keep an eye on your monthly electric bill — if you see a big increase in your kwh usage that may indicate a problem with your system. Third, keep trees trimmed that are near your house, both to minimize shading and to prevent squirrels from building a nest under your panels.
