Solar panels work by allowing light into the solar cells. ...
Due to the upwards angle of solar panels they are more prone to bird droppings and a build-up of general dust and dirt that does not wash off with just rain.
This reduces the amount of light hitting the panel and reduces its output.
Most manufacturers recommend cleaning at least twice a year.
This tends to result in a 3 to 5% increase in efficiency.
You can include a solar panel cleaning as part of your spring cleaning routine its entirely up to you.
