With more than 500 megawatts of installed capacity, the German company is one of the most experienced project planners and operators of solar power plants. Other solar parks belonging to the German and international company are also currently undergoing the TÜV Rheinland certification process.
Extensive catalog successfully tested
A total of more than 200 detailed quality criteria were checked in order to obtain the TÜV Rheinland certification. The test categories are safety, conformity with standards, functionality and output. The criteria cover planning, including supplier and component selection, site and yield certification, installation, commissioning with technical inspection of the systems and extensive documentation as well as technical maintenance and monitoring of operations. Technical specifications are also drawn up to ensure the quality of the individual system components, including for modules, the substructure, inverters, connection boxes and cabling. The criteria included in the catalog of tests go way beyond the basic requirements of component certification and also include requirements specific to the particular systems or site.
Defects in large-scale power plants ruled out
The independent certification of large-scale photovoltaic power plants by TÜV Rheinland is a response to the high number of defects and frequency of faults in solar power plants. In 2013, TÜV Rheinland analyzed the incidence of faults at 125 large-scale solar power plants that had undergone their first inspection by specialists in recent years. They discovered that approximately 30% of all large-scale power plants inspected by TÜV Rheinland were found to have serious defects. These were either serious safety-relevant problems that required immediate action or significant accumulations of problems that strongly impaired the plants’ functionality. Half of all defects identified were installation errors, including inadequate or even dangerous cable routing, defective foundations or installation of support frames, defects with connections and grounding, and so on.
TÜV Rheinland assists with the construction of numerous solar power plants worldwide
