Summary:

Note to readers, attached is the complete final report for FNE94-067.

On June 6th 1994, the PVEV (photovoltaic electric vehicle) became a reality. We have used it all summer and fall, with tremendous success. Here is how it was done: we bought a golf cart; we bought a 3 photovoltaic modules of 100 watts each; we mounted the modules on aluminum supports bolted on the sides of the cart and then we connected them to a charge controller, to prevent overcharging and two batteries located under the bench seat. The modules thus serve as the roof of the cart, collecting energy while they keep us in the shade. Finally, we added a hauling tray on the back to allow us to take full advantage of the 700 pound payload.

Our solar input averaged 7 amps per hour at 36 volts, for about 5 hours per day, or 35 amp hours per day. The EZ-GO cart draws 50 amps @ 36 volts while its running. Therefore, the cart can run on its own solar power for about 45 minutes per day. We do have an electric charger, but did not have to use it at all once the modules were installed.
