Hi Carl, Here is the link to how Photon measures each module.
http://www.photon.info/photon_lab_modul_ertragsm_en.photon?ActiveID=1289 and http://www.photon.info/photon_lab_modul_ertragsmAD_en.photon?ActiveID=4382 Can you please tell me how they are doing it wrong, and what the test would look like in doing it right?
