How to Clean Your Rooftop Solar Panels at Home

June 03, 2024

India’s weather is often unpredictable. Due to heavy pollution and increasing global warming, many states experience humid conditions frequently. In numerous regions, both in summer and winter, heavy dust storms are common due to sudden climate changes. In areas with little or no rain, dust accumulates on solar panels, affecting their performance. 

When the dust layer becomes thick, it prevents the cells inside the panel from capturing sunlight and heat effectively. This reduction in sunlight absorption leads to a significant decrease in power generation. Insufficient energy production means relying more on the grid, which can be costly. Therefore, it is crucial to clean your solar panels regularly to maintain their efficiency and save on energy costs. 

Cleaning Your Solar Panels at Home 

Cleaning solar panels yourself can be challenging, especially if they are installed at a height. For safety reasons, we recommend hiring professionals to clean the panels. However, if you feel confident in doing it yourself, follow these easy steps: 

Step 1: 

Turn off your solar system. If you’re unsure how to do this, contact an expert at APS Solar for guidance. 

Step 2: 

Prioritize safety by using a harness or step stool, positioning yourself so you can see the panels properly. Avoid walking or placing weight on the panels to prevent microcracks, as most outer damage is not covered under insurance policies. 

Step 3: 

Use a simple and cost-effective method: spray water onto the surface of the solar panel array. You can use a hose or any tool to sprinkle water on the panels. 

Step 4: 

Gently clean the panels with a soft-bristle brush, then wipe them with a smooth cloth. Avoid harsh chemicals that could scratch the anti-reflective coating. 

Your solar panels are now sparkling clean and ready to harness the sun’s energy efficiently! 


Cleaning solar panels on your own carries risks. If you’re uncomfortable with the process, seek assistance from a professional cleaning service.
