I'm running in Estonia (59 degrees North) a 9 kW max output PV microstation with microlense coated PV panels NAPS Saana. Just curious if anyone has tested in comparable conditions efficiency of micro lens coated PV panels and traditional flat surface panels. My production so far has been about 30% higher from the value calculated by EU PV GIS calculator, which is considered as official source for production estimation to get gov-t support for installation. I'd like to know for possible future projects if the higher cost of the micro lense panels is justified.
