It is proven that over time contamination (due to bird droppings, dust, pollen, algae, moss) threatens the cost effectiveness of a photovoltaic (PV) system. Reduced performance and up to 30 % yield loss can be observed. The solar panels cannot be completely cleaned by rain only and there is a strong demand for professional assistance due to considerable risks and the inefficiency associated with manual cleaning. 4Washing has the answers!

• Removing light absorbing or reflecting pollution
• Increasing the power output of the panel
• Increasing the durability of the panel
• Maintaining the value of the solar plant

• Increased photovoltaic yield
• High cleaning performance thanks to soft-brush technology
• Stripe and stainless drying, even under direct sunlight
• Safe working conditions
• Environmentally friendly cleaning using demineralized water
