Residential Solar Cleaning

Our thorough cleaning process not only enhances energy generation but also extends the lifespan of your solar panels, protecting your investment for years to come.

Commercial Solar Cleaning

Our dedicated team of experts specialises in commercial solar panel cleaning, utilizing cutting-edge equipment and environmentally friendly cleaning solutions to ensure your solar array operates at peak performance.

Industrial Solar Cleaning

Using advanced cleaning techniques and eco-friendly solutions, we remove dirt, dust, debris, and other contaminants that accumulate on your panels, restoring them to peak efficiency.


When your solar panels are dirty, you are effectively losing money as the dirt is blocking the sun and reducing the efficiency of the panels. In addition to this, keeping your panels clean and well maintained will also increase the lifespan of your system.

Solar panels do not need to be cleaned frequently; however, dirt and debris can collect on the surface of your panels over time. To keep your panels working normally, you should clean them every six months to a year.

Typically, solar panels last 25 to 30 years. While their efficiency generally declines over time, the majority of panels still generate between 80 and 85 percent of their initial power output after 25 years. The inverter, which transforms the direct current (DC) generated by the panels into alternating current (AC), often has a shorter lifespan and may need to be replaced after 10-15 years.

The time it takes to recoup the initial investment in solar panels depends on factors such as the system’s cost, energy production and local electricity rates. On average, the payback period ranges from 5 to 10 years. Once you’ve reached the payback period, your solar panels continue generating free electricity for the remainder of their lifespan, resulting in significant energy cost savings.
