One of the best things about solar is that they require very little maintenance. In most cases, a quick wipe-down with a clean, damp cloth is all needed to keep them functioning at peak efficiency. However, there are a few things to keep in mind.  First, if your panels are located in an area with a lot of pollen or dust, you may need to clean them more frequently. Living in an area with heavy rains, you'll want to inspect your panels regularly to ensure that leaves and other debris haven't accumulated. Following simple tips, you can ensure that your solar panels provide years of trouble-free service.
