While basic maintenance like hosing off loose debris is fine, thorough cleaning requires specialized equipment and knowledge to avoid damage. Solar panels are more delicate than they appear, and using the wrong cleaning methods can void your warranty or create micro-scratches that reduce efficiency over time. Professional cleaning also includes safety considerations. Most residential solar installations require working on rooftops or accessing panels in awkward positions. We have the proper safety equipment, insurance, and experience to clean panels safely without risking injury or property damage. Additionally, professional cleaning includes system inspection. We often identify potential issues like loose connections, damaged seals, or mounting problems that homeowners miss. Catching these early prevents larger, more expensive problems down the road.
