Solar panels are designed to absorb the sun’s rays as a source of energy for generating electricity or heating.
Due to the upwards angle of solar panels, they are more prone to bird droppings dust and dirt that does not wash off with just rain. This build-up of Dust, dirt, pollen, bird droppings and other debris reduce the amount of light hitting the panels and adversely affect optimal Solar Panel Efficiency.
Cleaning solar panels that had been in operation for 15 months doubled their output of electricity.
Rain is not a satisfying way of cleaning solar panels. Solar panels that were cleaned professionally had a 12% higher output of electricity compared to those cleaned by rain. This literally means that they will generate 15-25% less electricity, which you will have to source from the utility company at their price rates. This easily adds a couple of years extra on the payback time. So it is important to clean solar panels in order to protect and maintain your investment.
Green solution for green technology
Regular solar panel cleaning will also help you to make the most of the government feed-in tariffs. Solar panels do not have any moving parts, which is why there`s not a whole lot of maintenance to take care of. However, cleaning is one aspect of solar panel maintenance that should not be taken lightly.
