Operations & Maintenance

Our 360 degree PV solution

The profitability and value of a PV power plant depend on its continuous monitoring and inspection. Our O&M service offers solar and battery storage system operators an all-in-one solution to secure and improve their systems. With more than 20 years of O&M experience, we monitor a total plant capacity of 2.1 GWp worldwide. We identify risks in plant operation at an early stage, initiate countermeasures and therefore enable optimal operation with highest possible availability.

Performance Services: Foresight thanks to Big Data

We always keep an eye on your solar power plant and count on our in-house SCADA control room in the process. Here, plant data from all over the world is being processed. With the help of archived solar data and an anonymous big data analysis, we are able to compare the operation of PV systems and advise customers accordingly. We link data from maintenance work and component service and can therefore carry out a foresighted O&M analysis. Selected component groups are monitored and countermeasures initiated even before a possible loss of yield occurs. In addition, we use weather and solar radiation data for a reliable forecast of future yields.

Technical Asset Management: Automated end to end-processes

From system monitoring and control to preventive maintenance: We offer solar investors and operators an all-in-one solution with fast response times and transparent reporting. Our O&M team is able to take over the entire technical operation of a PV power plant or battery storage system. We plan maintenance activities with the help of an IT-supported asset management system that takes all energy and availability influences into account. In this way, we are able to reduce downtimes to a minimum and ensure long-term protection of the systems.

Inspection & Maintenance: Safe and sound

In addition to monitoring and analysing plant performance, on-site inspections are very important. One of the main tasks of our teams on site: Regular technical system checks in accordance with the standards and regulations as well as immediate action in the event of a failure. We therefore make use of the latest technologies. It usually only takes a few hours between a fault report and on-site troubleshooting. We carry out maintenance and inspections in the low and medium as well as in the high voltage range. For our customers, we also coordinate tending of the greens, cleaning of PV modules and correspondence with network operators, nature conservation and building authorities.
