How to Clean Solar Panels on RV Roof: 5 Steps

How to Clean Solar Panels on RV Roof Cleaning Procedure

Proper cleaning is crucial when cleaning your RV’s solar panels. This will ensure that the panels are effectively cleaned without causing any damage to them. The following is a step-by-step guide to cleaning RV solar panels:

Step 1: Turn Off the Solar Panel System

Before starting the cleaning process, you must turn off the RV solar panel system. This step is crucial for safety reasons and to avoid damage to the panels. When the system is turned off, no electricity flows through the panels, reducing the risk of electric shock.

To turn off the solar panel system, locate the main switch or breaker box and turn it off. It is usually located near the inverter or charge controller. If you are unsure where to find these components, consult your RV owner’s manual or contact a professional.

Step 2: Remove Any Debris from the Panel Surface

Debris such as rotten leaves, accumulated dirt, and bird droppings can significantly reduce the efficiency of your solar panels. You can use a soft-bristled brush or a microfiber cloth to remove debris from your solar panels.

Ensure to avoid using abrasive materials that could scratch the surface of the panels. Begin at one end of the panel and move across, gently brushing or wiping away any debris.

It’s important to note that you should never use water to clean off dry debris. Doing so will only create mud that will be harder to remove later. Instead, use a dry method before moving on to wet cleaning methods like soap and water.

Step 3: Apply Cleaning Solution

For thorough cleaning, apply a cleaning solution to the panel surface after you remove debris. You can use various solutions depending on your availability and what works best for your panels.

One option is to use a soap and water solution. This simple and effective method involves mixing mild soap with water and applying it to the panels with a soft brush or cloth.

Another option is to use a vinegar solution. Vinegar can be mixed with water in a spray bottle and applied directly to the panels. This method may be particularly useful for people with hard water, as vinegar can help remove mineral buildup on the panels.

If you prefer a commercial cleaner, many options are specifically designed for cleaning solar panels. These cleaners often come in spray bottles or wipes and can be found at most RV or home improvement stores.

Step 4: Scrub with a Soft Brush or Cloth

Using a soft brush or cloth, gently scrub the panels in a circular motion to remove any dirt or grime that has accumulated on them. Be careful not to press too hard or use any abrasive materials that could damage the surface of the panels.

Step 5: Rinse with Water

After scrubbing the panels, it is important to rinse them with water. This step ensures that all the soap or vinegar solutions used in the previous steps are completely removed from the surface of the solar panels.

When rinsing the panels, it is recommended to use a hose with a gentle spray nozzle. Avoid using high-pressure water as it can damage the panels. Start at the top of the panel and work your way down, ensuring all areas are thoroughly rinsed.

After rinsing, inspect the panels for any remaining dirt or debris. If there are still some stubborn spots, you may need to repeat some cleaning steps until they are completely removed.
