Impact on Performance
Based on the simulation, shading losses are estimated to be 5% at the system level.
Due to the inverter status during the IR inspection (disconnection, open-circuit), the thermographic analysis could not take place to evaluate PID. Based on on- site IV curve measurements, the PID effect could be responsible for 10-15% energy losses.
An average soiling factor of 3% was determined from IV curve measurements of sample modules, before and after cleaning.
