The more light that hits a panel, the more power it will generate and store. Unfortunately 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 water. This is why we at Westcoast Windows & Gutters suggest to clean your solar panels in order to protect and maintain your investment. Our experts will restore and maintain the longevity of your solar panels so you do not have to worry about failed panels. Our goal is for you to get the maximum power generation.
