What maintenance is required for a solar electric system?
Keep an eye on your system’s energy output at least monthly. Your online monitoring system is the best tool for this job. Do a visual inspection of the entire system, even just from the ground, at least yearly. Look for any parts that have moved or show signs of mechanical wear or storm damage. Look for wires hanging down and any signs of animal damage. Binoculars might be handy for this.
That said, there are a number of potential issues that you will not be able to spot. We recommend a periodic comprehensive preventative maintenance inspection.
