Solar Powered Prius

The next breakthrough in hybrids will likely come from plug-in hybrid vehicle (PHEV) technology. Plug-ins allow the vehicle owner to recharge the battery at night when rates are lowest, allowing the vehicle to travel farther and faster on an all electric charge. PHEVs will get fuel economy up over 100 mpg for the average commuter. But, the battery technology is still a few years away.

In the meantime, there is a company called Solar Electrical Vehicles (SEV) which may give your Prius an additional boost today. Located in Westlake Village, CA, the SEV system recharges the battery in your hybrid via solar panels installed on the roof the hybrid vehicle.

The solar panels are made of high efficiency mono-crystalline photovoltaic cells, which can produce 215 watts of renewable energy. The system utilizes a 3kW supplemental battery pack, which extends the electric driving range up to 20 miles per day and improves fuel economy will range between 17 to 29% depending on driving habits, road speeds and conditions.

It takes 2 to 3 hours to install the custom molded low profile solar module, supplemental battery pack and the charge controlling system. The solar module is designed to last 30 years and it's maintenance free.

The SEV system costs between $2,000 and $4,000. Kits are available for the Prius, Highlander, Ford Escape Hybrid and Toyota Rav4 EV.
