s and potential-induced degradation (PID) in the module, which affect the overall performance of the module. The IR ther ographic inspection of PV modules is performed to detect non-conformities such as hotspot and diode failure. During thermo-graphic inspection the evalu
This laboratory can test more than 200 photovoltaic modules per day with an uncertainty of less than 3%. Due to its characteristics, it is capable of testing modules of up to 1400 x 2700 mm of different types (high efficiency crystalline modules, bifacial modules, thin film modules and PERC or HJT solar cells).
Due to the high number of photovoltaic panels required for the construction of new solar plants, cases have been observed where the final quality of the product is not as expected. This may be due to manufacturing defects, transport or handling problems, incorrect installation or inadequate maintenance.
The main purpose of these services is to facilitate effective management of possible deviations from the expected performance of the plant, thus ensuring maximum return on investment. DNV provides a variety of verification and inspection services in solar energy using a wide selection of test methods and testing technologies.
