Maintenance on your electric solar system is simple but must be done routinely in order for your system to be effective.
Cleaning the Solar Modules
Every 3 months it is necessary to have someone clean the surface of each solar module. The first thing you will need is a supply of clean, soft cotton rags and a hose (with a pistol grip sprayer) long enough to reach your solar array. Note; make sure whoever is providing the service is good on ladders and not afraid of heights.
