albedo dependent energy gain
albedo dependent energy gain high albedo: white roof, snow >> high bifacial modules: PERT, HJT medium albedo: gras, sand >> medium bifacial modules: IBC low albedo: water >> low bifacial modules: PERC+
summary - PV industry starts to be innovative - Cz-Si substrates are getting as cost effective as mc-si - PERC is coming strongly - Bifaciality is also picking up - n-type technology (or better PERT, IBC and HJT) still better for bifacial systems with middle and high albedo and for vertical E-W installations - bifacial IBC could become interesting in future as well 34
