We need more data on bifacial performance in order to simulate the performance. I've done some experiments with vertical bifacial TOPCon panels, and the lower production vs 45-degree tilt seems to be offset by the lower mounting costs. I run a solar company, and for ground mount systems the cost of the frames and foundations is more than the panels. With vertical PV it doesn't matter if power production is maximized, what matters is return on investment.
