When you prepare your van for a journey, don’t forget to clean RV solar panels if you use them. Clean panels work more efficiently and charge the batteries faster. Extra energy is something that you’ll definitely need in your travels. Here is a small guide on how to clean RV solar panels.
Choose the right time
The best time for cleaning is a cloudy day, early in the morning or late in the evening when the panels are cool. You can park your van in a shade as well. Don’t clean the panels when they are hot, as the glass can crack even from lukewarm water.
Gather the necessary equipment
Prepare a brush with soft bristles, a leaf blower, a non-abrasive sponge or microfiber cloth to remove stubborn stains, a mild detergent, and a squeegee to remove excess water after cleaning. If possible, use an extension pole to clean the panels from the ground to minimize the need for climbing on the roof.
How to clean RV solar panels depends what type you use. Thin-film panels are flimsier by nature. Go easy on them — a sponge or a cloth is enough. With rigid panels, you can be harsher.
Start the cleaning
Before driving into the cleaning process, turn off the solar system to ensure safety and prevent electric shock. Remove loose debris with a soft-bristled brush or a leaf blower. Then hose the remaining dirt and dust down with water. If you encounter stubborn stains, use a mild detergent to spot-clean the affected areas. Avoid using harsh chemicals as they may damage the panels.
After that, rinse the panels and use a squeegee to remove excess water and achieve a streak-free finish.
Hit the road
Give the panels about half an hour to get completely dry. While you’re at it, inspect the panels for defects, and check the electrical wiring and connections.
