We’re often asked, “How often do I need to clean my solar panels?”
Our answer will vary depending on several factors – but most importantly we consider the age of your system and the environment and surroundings. We’ve seen some PV array’s that have been installed for 20 years+ that are in terribly dirty states, and producing barely any generation. We’ve also seen systems surrounded by woodland, that have naturally built up a good layer of debris including leaves and pollen. We’ve seen large scale commercial PV systems that have succumbed to the inevitable elements of being in an industrial area including dust and pollution. And don’t get us started on bird droppings!
Here in the UK, we generally have enough rain to ensure our solar panels are not getting to much of a build up. The material of modern panel technologies and the usual tilt positioning will also help in ensuring rain washes any dirt away rather than building up too much as on a flat surface. We would never try and sell you a service you don’t need. But if you do have certain environmental factors that mean your panels could do with a little TLC, GB Solar have you covered!
