Light-induced degradation of silicon-based solar cells generally saturates above 0.1 suns [1] for the predominant mechanism of boron-oxygen defect formation; thermal degradation is also a factor [2] and likely to be unaffected by this geometry. But ERoEI for solar cells can be high, even in Europe [3] so, considering the roof replacement as a necessary cost regardless, these may still work out favorably, but at this juncture, only for special applications. 1: https://journals.aps.org/prb/abstract/10.1103/PhysRevB.69.024107 https://journals.aps.org/prb/abstract/10.1103/PhysRevB.69.02... 2: https://www.sciencedirect.com/science/article/pii/S1364032122001460 https://www.sciencedirect.com/science/article/pii/S136403212... 3: https://www.sciencedirect.com/science/article/pii/S0306261919317222 https://www.sciencedirect.com/science/article/pii/S030626191...
