Solar panel cleaning is essential for keeping them in optimal working condition and ensuring they’re as efficient as possible. Regular cleaning not only makes sure that the solar panels function at their maximum potential, but it also helps protect them against environmental damage such as dirt, dust, bird droppings, leaves, debris and other particulate matter which can hinder their performance. When these impurities build up on the panel’s surface they can cause a shadow effect on the panel itself – blocking out sunlight which would otherwise be used to generate energy. This means that if you don’t get your solar panels professionally cleaned regularly, your energy output could decrease significantly over time.
