Simulation of production CIS, CIGS vs. cSi modulen

Jan Mackovic

Recommended Posts

Simulation for CIS, CIGS modules production is significantly worse than for cSi modules. I can't believe that the difference could be so big.

For example: the same horizontal roof without rear ventilation, central Europe

PV*SOL: JA Solar mono cSi = 901 kWh/kWp, Miasole CIS = 829 kWh/kWp = 92% of cSi.

PV Designer Solar Edge: JA Solar mono cSi = 926 kWh/kWp, Miasole CIS = 913 kWh/kWp = 98,5% of cSi.

PV GIS (ERA 5)cSi = 877 kWh/kWp, CIS = 865 kWh/kWp = 98,6% of cSi.

Hi Jan Mackovic,

additionally to my answer as private message I want to point at the very bad low light performance of the CIS module. We allow manufacturers to put their low light data even in case the performance drops i.e. the values are probably wrong. You could use our PV*SOL model for CIS modules, which is way better than the manufacturers values but still a conservative value which usually slightly underestimates the real performance.

For being able to adapt this you have to copy the module in the database dialogue.

Best regards,
