Operation and Maintenance.
With Substance.
We take over all tasks of operation and maintenance and make sure that your photovoltaic system runs reliably and delivers the maximum yields.
Excellent service. Optimal yield. Sustainable added value.
Within the scope of O&M, we offer you an all-round service in the areas of monitoring, reporting, preventive maintenance and inspection, corrective maintenance and optimisation. We focus on large ground-mounted and rooftop systems from 2 MWp.
As an integrated PV specialist, we ensure the optimal operation of your solar system. We rely on many years of experience, technical expertise, efficient processes and personal commitment. Our own teams of experts are on duty every day to ensure the optimal operation of your solar system. In emergencies, we act immediately and take care of a quick, efficient repair.
In doing so, we always act in the interests of operators and investors – and also keep an eye on a commercially ideal solution in O&M. In this way, we ensure that our customers’ photovoltaic systems not only operate reliably and perform well, but can also expect a maximum service life. This brings us one step closer to the energy transition every day.
Our services at a glance.
Monitoring
We monitor your plant 365 days a year. On a daily basis, we identify faults via intelligent algorithms and manual checks and create regular medium- and long-term analyses to identify even creeping change processes in the plant performance. A separate data analysis division increases not only the efficiency but also the reliability of defect identification through new, automated approaches and processes for defect detection and analysis.
The cooperation between the plant hardware and monitoring software is actively managed by greentech to ensure secure, stable and trouble-free data transmission and controllability of the plant.

Plant and Incident Management
Plant and incident management continuously ensures the optimal operation of each plant and finds further optimisation potential. We know every plant – the components installed, technical and local peculiarities or special specifications and deadlines. We maintain a customer and plant-specific overview by working in established teams and deticated contact persons. A self-developed ticket system enables efficient processes and provides the necessary transparency about a plant and current measures at any time.
Experienced, authorised electricians and technicians work on the plants with greentech Fieldservice. In the event of time-critical incidents, we also have access to a Germany-wide network of competent service partners. In this way, failures are remedied as quickly as possible and at low cost, and plant operation can continue.

Plant and incident management
Plant and incident management continuously ensures the optimal operation of each plant and finds further optimization potential. We know every plant – the components installed, technical and local peculiarities or special specifications and deadlines. We keep the customer and plant-specific overview by working in fixed teams and fixed contact persons. A self-developed ticket system enables efficient processes and provides the necessary transparency about an installation and current measures at any time.
Experienced, circuit-authorized electricians and technicians work on the plants with greentech Fieldservice. In the event of time-critical incidents, we also have access to a Germany-wide network of competent service partners. In this way, failures are remedied as quickly as possible and at low cost, and plant operation can continue.

Our software tools
With an innovative IT landscape and efficient processes, we ensure optimal service and long-term availability of the PV systems we support:
Surveillance portal
Provision, analysis and storage of all technical plant parameters
greentech acts manufacturer-independently and offers monitoring solutions on other platforms in addition to greentech’s own monitoring portal “greensun” on request. In addition to a good price-performance ratio, a high degree of automation of the monitoring portal, user-friendly handling and good integrability to existing hardware, software and the existing IT infrastructure are important. Internal monitoring guidelines ensure that yield losses are reduced as much as possible through adequate and proactive action and that unnecessary trips to the plant are avoided. Upon request, our customers receive free access to the respective portal.
Operations Management Portal
Ticket system for documentation of all processes and events in the operating phase
greentech has developed its own ticket system that controls and digitally documents all processes and events for the technical operation of a photovoltaic system. It is also used to store all relevant information and contacts relating to the PV system and to have them at hand at all times. The system not only enables efficient and transparent work for high quality in technical operations management – it also ensures that no process remains unprocessed and workloads can be actively managed. In addition, the greentech ticket system forms the basis for regular reporting and coordination with our customers.
Mobile data acquisition
Documentation and control of all activities on the PV plant.
Through TabTool PV, greentech optimises the interfaces between office and plant on a daily basis. The industry-specific software solution maps supports planning, execution and documentation for repair, maintenance and inspection of your photovoltaic systems digitally and mobile. By using TabTool PV, all work is documented transparently, open items are tracked and assignments are handled efficiently – for short response times and low costs. Individualised Checklists ensure that all inspection points and work steps are considered and documented. Anomalies can be recorded in the blink of an eye including picture, description and location. All of this increases quality and efficiency of operations and follow-up.
