Module cleaning
Prevention of power losses and long-term protection of your energy yields.
We collaborate with experienced service providers who utilize modern technology to ensure professional, efficient, and gentle cleaning of all types of photovoltaic surfaces.
Depending on the location or roof pitch, natural environmental factors such as air pollutants, pollen, or bird droppings can cause significant soiling of the modules, leading to a reduction in their long-term performance.
To prevent performance losses, we recommend and offer regular, environmentally friendly cleaning. Upon request, we will gladly provide you with a personalized offer.
Transformer maintenance
All tests – one partner
To ensure both the functionality of the system and the health and safety of employees working on site, a transformer station must undergo various tests, which normally require separate technical teams to travel to the site and the systems to be shut down repeatedly.
Take advantage of the expertise of our electrical specialists and save time and money: we carry out all necessary tests in a single operation. This means that there is no need for different technicians and service providers to travel to the site and coordinate their work.
Our maintenance measures at a glance:
Protection test (mandatory)
DGUV V3 (mandatory)
Transformer maintenance (recommended)
Station maintenance (recommended)
Inspection and maintenance of medium- and low-voltage circuit breakers (recommended)
