Anyway they say you get an extra 30% better result by laying the frames over a white roof. Why not stick a reflective back layer to the frame and lock in that 30% for all users that would then give 14×1.3 or 18% which is very good if correct. I’m sure a proper back layer would be much better than any soso white roof.

This is really better called a micro concentrating PV.

Starting with standard PV sheets one can buy off Ebay for also nearly $1/W though would be quite difficult to add concentrating without building something that looks like a poor mans SunCatcher dish. Adding concentration hardware probably costs more that just using more cells unless its built right into the PV structure as Prism does.
