The best cleaning tools for solar panels combine effective dirt removal with surface safety, ease of use, and reach. Here are the top recommended tools and equipment based on expert and industry sources:
Essential Solar Panel Cleaning Tools
- Water-Fed Telescopic Poles with Brushes
These are among the most essential tools. Telescopic poles allow safe cleaning of panels up to 30 feet high without ladders, keeping the user on the ground. They often feature water-fed brushes that pump pure or deionized water through the brush head to loosen dirt and rinse panels in one step. Brushes have soft bristles designed not to scratch panel surfaces.
Example: Unger’s telescopic poles and hydro-pure water brush system are designed to clean without damaging panels and maximize energy yield. - Soft-Bristled Brushes and Scrubbers
Using only soft bristles prevents scratching. Brushes often come in various sizes with ergonomic handles for scrubbing off bird droppings, pollen, and dust. Some brushes have built-in squeegees to wipe water away after cleaning for streak-free drying.
Example: The EVERSPROUT 5-12ft scrub brush has soft bristles and an integrated squeegee, suitable for delicate cleaning without scratching, extending reach up to 20 feet. - Pure (Deionized) Water
Solar panel manufacturers strongly recommend using distilled or deionized water for cleaning. Tap water with minerals can leave deposits that reduce efficiency and damage panels over time. Pure water cleaning ensures a spot-free, streak-free finish without chemicals. Systems like the Unger HydroPower® use this approach. - Squeegees
Handheld or attached to poles, squeegees effectively remove water without scratching or damaging the glass surface of solar panels. They help ensure dry, clear panels after washing. - Non-Abrasive, Mild Cleaning Solutions
When cleaning with liquids beyond water, only mild, non-abrasive soaps or cleaners should be used to avoid damaging the panel surface or sealing. Some users prefer just pure water for safety. - Safety Equipment
Sturdy ladders and harnesses are recommended if panels are not ground-mounted and cannot be reached fully by poles.

Key Usage Tips
- Clean panels during cooler parts of the day (morning or evening) to prevent thermal shock from cold water on hot panels, which can cause cracking.
- Always power down the solar system before cleaning, following manufacturer guidelines.
- Use gentle pressure and soft brushes to avoid scratches.
- Remove loose debris first before applying water or cleaning solutions.

Squeegees help finish drying without streaks. Leading products like the EQUIPMAXX water-fed pole kit and Unger’s system are highly recommended for their build quality and effectiveness. For more budget-friendly options, the Camco and EVERSPROUT brushes offer great value for less demanding setups. Proper technique and safety gear are also essential for effective and damage-free cleaning.
