Solar panels are pretty light weight compared to snow loads.

  The parent comment is that the roof is designed for the structural load of the snow load and not much else. Solar panels need ballast, racking, thick teck cable, etc and can easily overload the structural design. I’ve just gone through this on a warehouse I own. Cheaper to build over the parking lot than add structural reinforcements for every column.
