Impact on Performance
Soiling measurements were conducted via short circuit current reduction and nominal power, before and after cleaning, with irradiations higher than 1000 W/m2. The estimated soiling factor is in the range of 4- 6.2%.
Due to near objects and microshading, the simulation estimates near shading losses of ca. 4.3% on system level.
Based on the crack distribution and type found during the electroluminescence inspection, the module nominal power could be reduced by 4-8%. Furthermore, these types of cracks could eventually lead to inactive areas and higher power loss in the midterm.
