This service is dedicated to customers who face insufficient performance or visual changes in PV modules, occurring in field operation, after accelerated aging tests or directly after module production. With the help of our 5-step plan the root causes or failed materials are located in a fast and goal-oriented manner. Through a stepwise approach, the analysis can be followed to the level of detail as desired by the customer. Thus, it is possible to meet the aims and questions in the most efficient way, from the first basic analysis to the exact identification of the failure mechanism on material level.
