This paper summarizes the results of solar photovoltaic (PV) module electrical characterization under outdoor and indoor conditions in the Republic of South Africa. Under outdoor conditions, the bi-facial PV modules on fixed racks and dual-axis trackers yielded more energy than mono-facial modules on the same mounting configuration due to the active backside. The indoor current-voltage (IV) measurements conducted on an A+A+A+ sun simulator matched within ± 3% of the manufacturer’s nameplate ratings on a sample of crystalline PV modules, with some exceptions. The measured electrical characteristics from the outdoor system was corrected to standard test conditions (STC) and compared with indoor measurements at STC. The corrected maximum power from the outdoor system measured roughly 5% below maximum power as measured on the indoor system.
