Commercial and industrial photovoltaic systems

Producing electricity cost-efficiently with a consistently safe investment in the photovoltaic system  

In the field of commercial and industrial photovoltaic systems, TEP’s main focus is on roof systems and façade projects up to approximately 1 MW. However, other applications are not excluded. The integration of different energy systems such as photovoltaics, battery storage or hybrid systems for diesel generators for emergency power supply are common. The integration of electromobility applications is also supported. When implementing photovoltaic systems, TEP relies on the highest safety standards and uses glass-glass solar module technology as well as “Made in Germany” products and technology.

Service and Maintenance

Optimum revenues and maximum returns demand trouble-free plant operation

After the successful commissioning of your plant, TEP also takes over the technical plant monitoring. This is done not only by remote monitoring, but also locally on site by our partners. In addition, the TEP service teams checks the systems regularly and carries out maintenance work or repairs on site if necessary. This ensures that the plant and its operation are in perfect condition. During the entire operating period, power generation can be continuously maximized, and downtimes minimized.

Our services in the field of after-sales services are detailed:

  • Ensuring operational availability and performance ratio (PR)
  • Remote monitoring of plant operating data
  • Preparation of monthly operating reports
  • Tracking maintenance cycles and monitoring warranty periods
  • Corrective maintenance
