It's not that flashy, but Aries RC's concept is impressive nonetheless, and he has all the tools to do the job at a fraction of the cost (excluding his time) using readily available parts.
The weak part of DIY solar roof tile is of course that you then need to produce some 2,000 of them to cover a home, which is a lot of work for an actual working and installed DIY project.
Aries RC used:
standard solar wafers, soldered together to form a single 6 inch by 6 inch cell
3/16 inch tempered glass trimmed to size and combined with a custom gasket
thin micro-louver film normaly used to protect privacy of laptop screen
small heat pads
