Solar systems are built to last for a long time, and hence require little maintenance.
That being said, a lot can go wrong, which will affect their productivity resulting in expensive solar panel maintenance cost.
No matter where you live, bird droppings, biological deposits, dust from busy roads, twigs from nearby trees are some of the common deposits that can adhere to the surface of your panel, thus, resulting into a low sunlight capture and reducing the amount of electricity generated. This situation occurs mostly in old panels as newer panels are self-cleaning.
