Get the thumbs up with your solar powered Hyper Efficient Prius.
Attempts to power hybrid cars with solar panels have been around for a few years. But now a company called Solar Electrical Vehicles is producing commercially available after-market panels for hybrids, starting with the Toyota Prius. The fiberglass, molded panels fit on top of 2004-2007 Prius models. They are attached using an epoxy glue. Unlike previous attempts, these panels fit the curve of the roof.
