Choosing the right company to clean your solar panels is crucial. A good cleaner should have specific training and proper insurance, ensuring a safe and effective service. Here are key signs of a professional provider:
- Certifications and Training: Reputable cleaners often hold industry certifications (e.g. ISCA training) and follow best-practice standards. Industry guidelines recommend that solar cleaning crews be trained specifically for PV systems and use detailed risk assessments (RAMS) for safety. UKSPCA members meet these high standards.
- Insurance and Safety: A trustworthy firm carries public liability insurance and follows safety protocols. Cleaning involves working at height, so ask if they use harnesses or special access equipment. One expert guide warns that “working at height in a wet and slippery environment can be incredibly dangerous” and recommends hiring a professional for roof workcheckatrade.com.
- Proper Equipment and Methods: Professionals use soft-bristle brushes, squeegees, and purified (or rain) water to clean. They never use high-pressure washers. In fact, one cleaning service points out that pressure washers are “too violent for the technology” and can damage PV cellssoftwashdoctors.com. Ensure your cleaner uses gentle, eco-friendly solutions – harsh chemicals or abrasive tools can void your panel warrantysunsave.energy.
- Transparent Quoting: A reputable company will provide a clear quote, explaining whether they charge per panel or by site. They should answer questions about cleaning frequency and methods. If a price seems too low, make sure it’s not because corners will be cut.

Finally, ask about warranties. Some manufacturers require proof of regular cleaning to honor the warranty. As one expert notes, panels should be “professionally cleaned according to the manufacturer’s instructions” or the warranty may be invalidatedcheckatrade.com. A top-notch cleaner will document their visit (e.g. receipts or reports) and follow any manufacturer guidelines.
