you can find an all-glass roof sunshade for the model s here for the near 100% solution:
sunshade for tesla: model-s: 2012-2017 auto heat shield

but living in houston and driving around texas last weekend in the high 90's, the glass roof was not where the heat comes in - it's the front and back glass even with ceramic tint. the tint let in more palpable heat than the roof - but it was negligible and the a/c even on range mode (half power) was barely running most of the trip.

definitely the texas folks know what's cookin'... i have the autoheatshield for the glass roof installed, and it goes in two pieces, it has massively cooled things down in the direct sun... suction cups keep it secured. we desperately need a retractable shade for the all glass roof... i'm tired of wife saying, "for such an expensive car, i can't believe it doesn't come with that" and i yell back, "i like it that way!" and she says... "then why do you have the heat shield installed"... and i mutter under my breath... "you're a heat shield"
