solar power?

so I've been thinking about it, and i want to know if anyone is working on Solar panel shingles. the large block solar panels are unsightly, especially on older homes. Also the technology for Solar Parking lots is already being used.
seems like there could be the base strips put down- like the black paper... w/ evenly spaced hooks, then the shingles would lock onto the hooks, and be equipped to draw solar energy.

so i asked Google.
