I currently have 325 watts of solar panels on the roof of my RV. This year, I will install solar on the roof of my RV port to power my 880 sq foot home and recharge the batteries on my RV while it is under said roof.
There is no reason that I cannot provide a plug to charge the batteries in my NEV and in any phev that I purchase in the future.
Can panels survive driving down the road, sure, thousands of us have them on our Rvs but they would look pretty clunky on the Volt. Perhaps the new film type panels or even panels molded into the body would be appropriate. However, living in SW Texas, I don't put my vehicles out in the sun when parked.
My plug in scheme from solar on the roof of my RV port/house would be the best option. I'm looking foward to viable PHEV to complement my NEV which is basically a golf cart on steroids. Come on VOLT!
That's why I prefer NiMHs. I hope they have fixed that for the Volt.In my fuel cell & battery class I am taking now, I just learned that Li ions batteries are suggested to be stored around 58 degrees F to try and reach a 5 year life span. Excess heat (like parking outside in hot climates to charge via solar) suggests the life span of the battery will be shortened greatly (no greater than 3 years).
Now, granted, there are tons of Li based batteries, but that was a general assumption on all Li based batteries.
Well maybe there is something innovative like prolonging the life of the batteries that the solar power could be used for as well as keeping the inside of the car from reaching 140 degrees when parked in the sun. It just isn't going to be very beneficial for powering the car (charging the batteries) for those that have short commutes.
