I installed 50 year warranty asphalt shingles on my new roof, under the solar panels.

Glass solar shingles seem like they have the opposite problem - the shingles probably will outlast the solar cells. And installing them is a bit of a pain - they have to sit on a set of light purlins, to allow for the wiring. This requires a reworking of the trim at the edges of the roof.
