Solar panels are a great addition to a property, and once they’re installed, many people believe you can leave them to start generating electricity without any maintenance. However, this isn’t the case, as solar panels are like any other external part of your property, and they do need regular cleaning. Once they’re installed, they’re outside all day, every day, through all weathers. Gradually, dirt and dust will build up and reduce the energy efficiency of your panels. Luckily, here at Willis’ Cleaning Services, we can help you get the most out of your solar panels.
