Solar Roof for the Prius

The Prius is already one green vehicle, and here’s another way to make it even more so with the SEV Solar Roof Module. Fitting snugly onto a stock Toyota Prius roofline, it offers 215 watts of energy that helps you drive without consuming a drop of fuel for an additional 20 miles per day. No plug-ins are required as regular sunlight would do. It takes approximately 2 to 3 hours to install and comes with a battery pack. The return on investment has been rated at around 2 to 3 years, so a simple mental calculation would mean the initial cost might be out of reach for some.
