This sounds sweet, but heat might be an issue. Typical solar installations stand off from the roof, providing both insulation against the heat of the dark panels (yeah, some of that goes to electricity, but much of it doesn't) and airflow that can cool the roof and the panels -- which don't like to be that hot.

How does it work on shingles, not to mention tar & gravel roofs? If it's so light could blow off in moderate wind when the bond fails. Thermal expansion of different materials, might as well spray it on, which already has been investigated.

Looks like well suited for mobile applications! Like the top of Guzmanchinkys sprinter!

This is pretty awesome!
Specially if they will cost similar or less than traditional panels, it will give so many more people access to solar electricity

Hmmm, so nothing new then? UniSolar was doing this decades ago.

as usual missing the all important information about efficiency and cost per watt produced as compared to conventional ones

Wind will tear them apart.

Never seen a flat roof yet they are either corrugated or ridged profile. I think flat A/C sheets went out a long time ago, well after even they turned corrugated.

How about snow build-up, water pooling etc. I'm no engineer but the applications seem very limited..

Stick them to roof, trunk and hood of battery-electric cars.
