“…Next, data will be analyzed of the actual monitored long-term performance, defects and failures in PV systems installed all over Europe to quantitatively determine the absolute influences of components rated performance, key design of systems including BIPV, residential, field-based and floating systems, installation, operation, maintenance practice, geographic location and weather/climate factors on the performance, performance degradation over time and failure modes of these PV systems. Guidelines for analyses have been recently reviewed, and will be used as basis for analysis [9]. Close collaboration with IEA-PVPS-Task 13 is foreseen and guaranteed as many PEARL-PV participants are also active within IEA-PVPS-Task 13 [10].…”
