Dust and dirt on solar panels causes constant problems and this builds up grimes over the years. PV arrays situated in dustier areas or near farmland or next to the main road needs special maintenance. Bird droppings rather than dust on your solar power panels are more damaging. If many trees surround your house, your solar panels will be covered not only by leaves but also by bird’s droppings. A lot of build-up and debris is caused over time due to both these reasons, making it more important and regular to clean and maintain your solar panels. We would recommend using experts to ensure your system is cleaned up to the best possible standards.
