Low light intensity losses


Recommended Posts

Dear Berend,

yes, this is possible. It depends on the module characteristics and the distribution of irradiance intensities.

This module (used in the project that you sent to our hotline, thanks for that) has a positive relative efficiency in the irradiance range between 200 and 1000 W/m² (light grey curve is slightly above 100%).


In relative terms, the module is therefore a little more efficient in the range of 200 to just under 1000 W/m² than under STC conditions; only below 200 W/m² does the relative efficiency drop. With such modules, you can often see a positive effect of the low light behaviour.

Kind regards,
