Black backings produce ever so slightly less than white backsheet, and premium panels can technically be worthwhile if you have limited roof space like we do.

- baking 8y agoI think they are talking about the cells themselves. Black cells have higher light absorption than blue cells (which are reflecting blue light) but I can't speak for their efficiency (and I should note that absorbed light that doesn't generate electricity generates heat which is bad for PV efficiency.)
