Tips on How to Clean Solar Panels for Your Home

Solar panels are one of the most trustworthy, efficient, cost-effective, and environmentally friendly sources for generating electricity. They work by transforming sunlight into electrical energy. The more sunlight that reaches a panel, the more solar energy it will generate. Solar panels are more vulnerable to bird droppings and a build-up of general dust and debris that doesn’t wash off with just rain due to solar panels’ upward angle. It decreases the amount of light that reaches the panel and decreases its output. It is because of the same reason that solar panels for your home require proper maintenance and care.
