Hello, I tried using version 8 with a bifacial system in multiple orientations. When I simulated it apparently only calculated the Global incident on ground for bifacial gain on my first orientation (see attached figure). In this case this sub-array was only 0.68 MWp compared to the full system of 28.76 MWp so the reduction in bifacial side production was quite noticeable. Is version 8 supposed to calculate bifacial gain for all orientations or will it only calculate for the first defined orientation?
