Guide to Solar Panel Cleaning

Welcome, solar enthusiasts! Maintaining clean solar panels is key to maximizing your system’s efficiency. Dust, debris, and bird droppings can reduce energy output, so regular cleaning is essential. This guide covers everything you need to know about keeping your panels in top shape.

Why Clean Your Panels?

Clean panels ensure maximum efficiency. A dirty array can reduce your system’s output, affecting your energy savings.
