Full-Service PV Operations


Cooperating with a professional service provider allows you to focus on your core areas of business. As a specialized partner, we take over all of the tasks associated with the professional operation of solar power plants. We will take care of both the technical and commercial management, making the operation of your solar plant a 100% integrated process.

Another advantage that our complete PV package offers is proactive performance analysis. We will ensure that the returns on your investment remain on a high stable level. In order for us to do so, the operating data is continuously monitored in our control room, and it is also analysed by our PV specialists. As a result, even minor disruptive factors can be detected at an early stage and remedied quickly by our employees on site. Moreover, all preventive maintenance activities and the regular cleaning of the solar modules, the corrective maintenance and any optimisation needs that emerge for the photovoltaic power plant, are also taken care of.

Due to clear roles and responsibilities within the organisation, a rigorous IT system and dedicated key account support, we ensure that your requirements are implemented quickly and reliably.
