Solar panels are a great way to use renewable energy in your home, but over time. They get really dirty. In order for your solar panels to work efficiently, it is best to clean solar photovoltaic panels, especially when they are particularly dirty. In this article, we will teach you how to clean solar photovoltaic panels. In addition, other common questions about clean solar panels can be addressed.
Manual cleaning brush cleaning steps:
2.Spray the panel using the hose. After flushing away loose dirt and debris adhering to the surface. Subsequently, the solar panels and the surrounding roof are rinsed using a garden hose equipped with a spray function. This loosens the dirt and simplifies the subsequent wiping of the panels. Special note: If the panels are hot, do not spray them directly with cold water, as the rapid temperature change may cause them to crack. You should wait for it to cool down before cleaning, or switch to warm water for rinsing to avoid damage. At the same time, please avoid using high-pressure cleaning equipment, as the high intensity of water pressure may cause damage to the solar panels.
3. Use a long handled roof cleaning brush (or sponge if you are on a roof) to apply the cleaner to small areas of the solar panels. Allow the cleaner to sit for a few minutes to break down the stain, then gently wipe it away. Repeat for each area until the solar panels are thoroughly cleaned. If the panels are out of reach, try wrapping a soft cloth around the cleaning brush on the extension pole.
CAUTION: Avoid harsh chemicals, such as bleach, which can damage solar panels and pose a threat to neighboring wildlife. Please do not use rough brushes likewise can cause scratches and damage to the panels.
4.Grab the water hose and rinse the panels again, making sure all the cleaning solution is washed off let them dry naturally in the sun.

Conclusion
Solar panels are less efficient if they are covered in dust. Solar panels consist of photovoltaic cells designed to capture sunlight and convert it into usable energy. In order for the cells to fully absorb the sunlight, they must remain free from debris or dirt, which emphasizes the importance of keeping solar panels clean.
Solar cleaning brushes are available in different types (manual or electric), products (Double head, single head, rolling brush), sizes (3.2/5.5/7.2 m or 4.8-9m), power supply programs (AC power version, Lithium battery version, Dual power version, Motor (Bldc, Brush).
