I don’t know anything about this, but wouldn’t low 80s still be far better than standard roof material? I’m guessing your average roofing, like shingles, absorbs +90% of solar energy?

Yes but at that point you may simply use classic white paint I guess. Also one thing to consider is that going front 90% to 80% may not look like a big difference but that's still doubling the heat that comes in
