For those that just can't get green enough, here comes a new accessory that will make your Prius even more deadly. The SEV Solar Roof Module is essentially that. What makes this vehicular solar panel a bit better than the average bear is the fact that it installs seamlessly onto the Toyota Prius roof. The entire roof-panel is replaced with these solar cells and can provide 20 miles of electric range as well as upward of 29-percent increased fuel efficiency. This module is capable of fitting 2004 through 2006 Prius models. Watch out, deaf kids! [SEV via TFRJ]
