The Official DIY Solar Panel Cleaning Guide for Homeowners or Businesses

Effective solar panel maintenance hinges on using appropriate tools and cleaning solutions. Soft brushes or squeegees on extendable poles are crucial for removing debris without scratching the panels. For general cleaning, distilled water is sufficient. For tougher grime, a solution of mild, biodegradable soap and distilled water is recommended to avoid damaging the panels' coatings.

For larger projects, we have found some success with using pressure washers; keep in mind that the use of pressure washers requires caution. They should be set to a low pressure and used from a distance to prevent damage to the panels. A wide spray pattern helps distribute water evenly, minimizing the risk of micro-cracks or dislodging the frames.

It’s critical to consult the manufacturer’s guidelines before using a pressure washer to ensure compatibility and avoid voiding warranties. Maintenance frequency should be based on environmental conditions, such as dust levels and bird activity, which affect panel cleanliness. While rainfall can naturally clean panels, it does not eliminate the need for manual maintenance in all cases. Adapting cleaning schedules to local conditions ensures panels operate at peak efficiency. At the end of the day, the main objective is to not inadvertently destroy or scratch the surface of solar panels - and it's not rocket science. Below we will cover what we think are some of the best tools for different size jobs. To keep it brief - if you have a couple panels, the most you'll need is a window washing kit and maybe some specific solar panel cleaner. If you have a larger complex system - incorporating a pressure washer is the way to go.

The DIY Team Recommends Getting this Solar Panel Water-Fed Pole

Employing a window cleaning brush on solar panels is an effective method for maintaining their efficiency and prolonging their service life. The process begins with attaching the brush to an extendable pole, ensuring that you can comfortably reach the entirety of the solar panel array without the need for ladders, thus minimizing the risk of injury.

• Preparation: Start by thoroughly wetting the solar panels with clean water to loosen any surface dirt and debris. This initial rinse helps prevent scratching the panels during the cleaning process.

• Application of Cleaning Solution: If the panels are particularly dirty or have stubborn stains, apply a mild, eco-friendly soap solution directly onto the panels or onto the brush itself. Avoid harsh chemicals, as these can damage the panel's protective coating.

• Gentle Scrubbing: With the brush on the extension pole, gently scrub the surface of the solar panels in a circular motion or side-to-side, covering all areas evenly. The soft bristles of the window cleaning brush are designed to remove dirt without scratching the glass or damaging the panel's surface.

• Rinsing: After scrubbing, it’s crucial to rinse the panels thoroughly with clean water, preferably using distilled or deionized water to prevent mineral deposits. Ensure all soap residue is washed away, as it can attract more dirt and potentially reduce the panel’s efficiency.

• Drying: Although not always necessary, especially in sunny conditions where the panels will dry quickly and streak-free, you can use a squeegee to remove excess water, reducing drying time and preventing water spots.

Beyond the basics, there are advanced maintenance techniques that can further optimize solar panel performance and longevity. These methods, while more sophisticated, offer a deeper clean and can address issues not solved by standard cleaning.

1. Spot Cleaning for Stubborn Stains: For particularly stubborn stains, such as bird droppings or hardened tree sap, spot cleaning is necessary. Apply a small amount of isopropyl alcohol directly to the stain and gently rub with a microfiber cloth. This method breaks down the stain without damaging the panel's surface.

2. Anti-Reflective Coating Care: Solar panels with anti-reflective coatings require special attention. Use a pH-neutral cleaning solution to avoid degrading the coating. Regular checks for scratches or peeling are essential, as these defects can significantly impact the panel's efficiency.

3. Automated Cleaning Systems: For large solar installations, automated cleaning systems can be a worthwhile investment. These systems, including robotic cleaners and automated spray mechanisms, provide regular, efficient cleaning without the need for manual labor. They're particularly useful in areas with high dust levels or for installations that are difficult to access.

4. Thermal Imaging for Efficiency Checks: Thermal imaging can identify hot spots on the panels, which are indicative of potential issues like electrical faults or shading. Early detection of these problems allows for corrective measures before they lead to significant efficiency losses.

5. Professional Inspections: Even with diligent maintenance, scheduling professional inspections can uncover hidden issues. Experts can perform electrical system checks, ensure structural integrity, and recommend specific care for unique panel types.

What to Clean Solar Panels With

Using a Pressure Washer on Solar Panels

Utilizing a pressure washer for cleaning solar panels can expedite the maintenance process, but it requires careful handling to avoid damage. Here’s a structured approach to using a pressure washer safely and effectively:

• Selecting the Right Pressure Washer: Choose a pressure washer with adjustable pressure settings. Opt for a model that allows you to use a low-pressure setting, as high pressure can cause micro-cracks in the solar panels or damage their frames.

• Preparation: Begin by ensuring that the pressure washer is set to the lowest effective pressure setting. Attach a wide-angle nozzle to distribute the water evenly across the panel's surface, minimizing the risk of concentrated water pressure damaging the panels.

• Initial Rinse: Start with a gentle rinse using plain water to remove loose dirt and debris. This step helps prevent scratching the panels when applying more direct pressure. Maintain a significant distance between the nozzle and the panels — at least a few feet — to further reduce the risk of damage.

• Applying Cleaning Solution (If Needed): If your pressure washer has a detergent dispenser, fill it with a mild, biodegradable soap solution compatible with solar panels. Avoid harsh chemicals. Apply the solution evenly across the panels, taking care not to use high pressure. Allow the solution to sit for a few minutes to break down stubborn grime.

• Gentle Washing: With the pressure washer on a low setting and using the wide-angle nozzle, gently wash the panels, moving in a consistent, sweeping motion. Keep the nozzle moving to avoid focusing the water stream on any single spot for too long.

• Final Rinse: Thoroughly rinse the panels with clean water to remove all soap residue. Again, ensure the pressure setting is low and the nozzle is kept at a safe distance from the panels.

• Inspection and Drying: After washing, visually inspect the panels for any remaining dirt or soap spots. Although solar panels typically dry well on their own, you can use a clean, soft cloth or squeegee to remove excess water, especially if the water in your area is hard and prone to leaving mineral deposits.
