Your specialist for cleaning large-scale solar installations. Solar parks, businesses, distribution centres, agricultural sector and industry. Fast, sustainable and demonstrably effective cleaning.








Cleaning your solar panels ensures that they maintain their optimal performance over their lifetime and reduces the risk of technical problems.
Clean panels can operate at their maximum capacity, resulting in more energy generated and thus lower electricity bills or higher revenues when fed back to the grid.
With the standard monitoring software of the PV system, the percent accurate measurement of (light) contamination is difficult, this because there are several aspects that can affect the yield.
With our so-called “flash tester,” we can measure to 0.1% accuracy the difference between a dirty and clean solar panel. At more than 2% yield loss due to pollution, it pays to have your solar panels cleaned. Ask about the possibilities of having Solarwash visit you with the flash tester.
Many insurers require the SCIOS Scope 12 (periodic inspection of the entire PV installation). During a SCIOS Scope 12 inspection, it may be advised to clean the solar panels if it appears that dirt is negatively affecting performance.
Although dirty solar panels do not directly cause a fire, they can contribute to conditions that increase fire risk. Therefore, it is important to clean and inspect solar panels regularly as part of a proper maintenance plan.
Solarwash is accustomed to working in accordance with the highest safety standards. Solarwash mostly works on behalf of multinationals, where high safety requirements are imposed. Our standard work equipment includes work shoes, reflective jacket and suitable work clothes. All our vehicles are standard equipped with all necessary PPE for every situation. All employees have VCA, VOG and AWP certificates.
Solarwash is committed to sustainability. For example, we only clean with osmosis water filtered on solar energy. All our vehicles are equipped with a battery pack with (clean) solar panels to power the water pumps and osmosis filter. Our cleaning equipment (electric brushes and robots) are charged with solar energy and are optimally water efficient.
Clean panels can operate at their maximum capacity, resulting in more energy generated and thus lower electricity bills or higher revenues when fed back to the grid.
Regular cleaning can prevent technical problems (such as hot spots, microcracks and sealant edge damage), resulting in reduced replacement costs.
