Do you have to clean your solar panels? Of course you do!
Pollen, dust, dirt, bird droppings, soot, pollution, and organic matter such as leaves will undoubtedly settle on your solar panels. Luckily, a good heavy rain will wash away a good bit if the debris but will not totally clean your panels. Over time, a thin layer of grime will develop and hinder your solar panels from getting the sunlight they need. This film will prevent them from preforming at their best. Think about what your vehicle would look like if it were never washed!
Google conducted an experiment at their solar farm in Mountain View, California. They cleaned panels that had not been cleaned in 15 months and found that their output nearly doubled! When they cleaned them 8 months later their energy output increased by 36%. Google concluded that regular cleaning of solar panels was “the number one way to maximize the energy they produce”. Adopting a solar panel maintenance routine will keep your panels operating at maximum efficiency so you can reap the full benefits of going solar year after year.
