Maintenance 

Part of Solar maintenance is the process of keeping solar panels clean and free of debris. This is important because solar panels need to be able to absorb sunlight in order to produce energy. Solar panels can get dirty from things like dust, pollen, and bird droppings. If they are not cleaned regularly, they will not be able to work as efficiently.

Another aspect is Electrical Testing is to ensure electrical safety of the solar equipment and to maintain a healthy efficiency of the system.   

Lastly don’t forget the bird protection to prevent the likes of pigeons nesting under the panels.
