Personally I think it's far less. Their IP is about the coloring alone, not the PV cells, so I'm guessing $5 per m2 of glass. So the 50k of sqm's they mentioned I think would bring them about $250k. I hope my numbers are too conservative -- we shall find out soon enough.
But even at $5/sqm, the revenue potential is huge. It's not unreasonable to hope that 10% of all new PV (and Solar Thermal) panels in certain countries would want colored panels, and they are the only viable option out there. That could mean royalties of $150 million annually (based on capturing 10% of a 25GW annual PV installation rate).
Of course 2014 saw 50GW of PV installed, and the growth is> 40% / year, so come 2020 this little company could be doing very very well indeed if they get several major players to use their colored glass.
