The FVK4-E brushless brush represents a technologically advanced solution for cleaning photovoltaic systems, designed to offer high performance while fully respecting delicate surfaces.
Equipped with a lightweight and durable aluminum frame and a nylon brush with a diameter of 150 mm and a length of 60 cm , this machine is perfect for professional washing operations on both ground-mounted photovoltaic systems and roofs.
This rod is telescopic
The 150W brushless motor ensures efficient and silent operation of the FVK4-E, powered by a 24V and 26Ah battery , with an autonomy of 4-5 hours. The FKV4-E motorized brush can operate up to a maximum pressure of 30 bar and consumes 22 L/min , working with liquids up to 40°C. The operating consumption is approximately 2 bar for 6/7 L/min .


The FVK4-E brush is built with an aluminum frame , a material that combines corrosion resistance and lightness, ideal for use on elevated surfaces such as photovoltaic panels.

Below are some details of the back of the K Solara FKV4-E.


The 150 mm diameter and 60 cm long nylon brush ensures effective yet gentle action, preventing scratches or damage to the modules.
