About us

The best technologies for real world situations emerge from a practical solution. Especially, when it comes to solving concrete problems. This is also the case when creative people, technology enthusiasts and competent users don’t settle for the status quo anymore.

The solar cleaning plant SunBrush was created to tackle this discontent. The photovoltaic plant of Franz Ehleuter was prevented from yielding any substantial revenues by strong snowfall in 2008; it happened right here in the extremely sunny region, Allgäu, in the south of Germany of all places, which was also the place where the first SunBrush was built.

It was an unacceptable situation for Ehleuter. This is why he and his collegue invented SunBrush – a solar cleaning plant which sweeps away dirt, bird droppings and dust from the solar panel. It is equally suitable for removing of masses of snow from the photovoltaic system. The plant used to be thoroughly thought through and tested at Ehleuter’s own shed at home where it was used to clean smooth surfaces, but shortly after that, won over the entire sector. The products were patented. Leading producers of solar panels are enthusiastic about their quality and since that time they have been recommending it for the implementation on their modules.

From the small village of Lachen into the world: Solar cleaning plant brush

The success was not achieved overnight, however, after the invention and production of the first SunBrush solar cleaning plants it is still far from over. Nowadays, the company SunBrush mobil GmbH supplies operators of solar equipment all over the world.

The solar cleaning plants from the Allgäu area are highly valued even in desert regions. They can be used for dry cleaning as well as for wet cleaning. They also save water considerably – which is just as important for Dubai as it is for Senegal or Turkey. Especially at those places where sand and dust prevail, it is important that the solar system is cleaned regularly in order for the solar panels to work with maximum impact.

The production of the solar cleaning plants goes hand in hand with established principles: efficient and save solutions, simple handling and adaptability to respective local circumstances.

This is why since its invention, almost no modifications have been made on the proven construction of the standard model: The technology of Sun Brush mobile is continuously improved and adjusted to new situations. A cleaning brush, made out of weather-resistant polyethylene and that was developed to clean glass in particular, is attached to a rotatable arm. Then you can simply install it to the photovoltaic system or, as in the case of SunBrush mobil, on a standard commercial vehicle; which should already be available in most customers’ fleets. This rotatable arm can be installed to almost any standard commercial vehicle and can be operated from them. A joystick is used for controlling the machine. A water tank with a hand pump can be placed on the vehicle’s rear if you like to wet clean the modules and surfaces. In addition to that, the solar cleaning plant can be extended by GPS and useful diagnostic tools.

A smile for the small village of Lachen: local manufacturing but international distribution

“Variable brush solutions to clean photovoltaic systems” – This is the description under which the products of Sun Brush mobile are distributed. Behind all this, is an innovative technology created by practitioners for practitioners. We work together with important partners in research and development – for example with the Institute of Energy and Drive Technologies of Ulm university– in order to secure and develop the high quality and efficiency of our cleaning solutions for photovoltaic systems and facades.

In spite of the worldwide distribution, manufacturing of the solar cleaning plants still remains regional, in the beautiful Allgäu. This is why no matter how snowy or sunny the day might be, the company SunBrush mobil GmbH makes the residents of Lachen and local engineering companies – for which Sun Brush mobil GmbH has become an important customer – happy.
