In consideration GM's exellent work in the development of VOLTEC, the idea of having a sun acivated (Solar Panel) charging system is absolutley necessary. My many years of work and experience with Solar Panels having given me a high respect for the technology.
I bought my first panels in 1995 to charge my batteries which was running the house power for my Arizona Ranch. Since then, the panels are of a 100 times more effective per square inch of surface than they were then. This makes the roof surface of the Volt a great platform for a Sun Activiated charging potential. It would have a way of absorbing much of the direct sun rays which would actually result in a cooler internal tempature of the vehicle passenger compartment.
It would add some additional cost to the project but the Solar Technology is already developed and to apply it to the construction of the roof would not be so very expensive.
What does others think about this application to our VOLT?
