Your solar power system’s output may be reduced if your panels are covered in dust, dirt or grime. This blocks the sunlight out and reduces its efficiency. To get the full cost-saving benefit of solar power, it’s best to keep your panels relatively clean and free of debris.
Dust, dirt, pollen, bird droppings and leaves can all take their toll on the performance of your solar system. A regular cleaning can do wonders to improve its efficiency.
Often, natural rainfall will wash away particles of dust or dirt, but you may still need to give it a helping hand with your garden hose.
