How often should you clean solar panels?

The frequency of cleaning solar panels depends on a number of factors such as the location, climate, and local environmental conditions. Solar panel installers in Kent; Volta Green Energy, have prepared some general guidelines to consider:


1. Dust and dirt: If you live in an area with dry and dusty conditions, it is recommended to clean your solar panels more frequently. Dust and dirt can accumulate on the surface of the panels, reducing their efficiency. In these cases, cleaning every 3 to 6 months may be appropriate.


2. Rainfall: If you live in an area with regular rainfall, the rain can help wash away some of the dirt and debris from the panels. However, heavy rainfall may also result in more debris getting stuck on the panels. Consider cleaning them once or twice a year in areas with moderate rainfall.


3. Surrounding environment: If your solar panels are installed in an area with a lot of trees, near agricultural fields, or in an industrial area, they may be more susceptible to debris build-up. In such cases, more frequent cleaning, such as every 3 to 4 months, might be necessary.


4. Tilt angle and self-cleaning features: Solar panels installed at a steeper tilt angle (e.g., greater than 20 degrees) tend to accumulate less dirt and debris. Additionally, some panels have self-cleaning features designed to reduce maintenance needs. These factors can affect the cleaning frequency.


It's important to note that cleaning solar panels can be a potentially dangerous task, especially if they are installed on rooftops or at heights. If you are not comfortable or experienced in cleaning solar panels, it is recommended to hire a professional service or consult your installer for guidance on cleaning and maintenance.
