Quality inspections & approvals

Expert reports on system quality during construction, commissioning, acceptance and operation

This should already begin during the construction phase, accompanying new systems during commissioning and acceptance as well as existing systems when warranties expire, operator changes or anomalies occur.

DGS Berlin offers comprehensive analyses and tests to independently check the quality of a PV system. In addition to a comparison of the design with the planning and a visual inspection, the operating behaviour of your PV system can be evaluated with characteristic curve measurements, thermographic examinations, insulation and earthing measurements as well as evaluations of monitoring data. Together with leading testing institutes, further analyses of module quality can be carried out in the laboratory.
