I havn't seen this talked about so I am putting it out there. Has anyone figured out how to add a couple panels to a yakima roof rack and have them permanently charge the main cells?

This system would give you about 2.5 amps at 120v and its portable so it shuold hold up on a roof rack. Granted, it would take a week to fully charge a leaf but still, it would extend your range by 10-20%/day on sunny days and almost recharge totally over a weekend. [figuring 16-20 hours at 120v to fully charge via the evse at 10 amp, 10amp/2.5=4 so 4x20 hours = 40 hours, figuring 60% efficiency for 12 hours (average) would take 5.5 days to fully charge]. That would be 1/5th of the electricity needed per week which would ammount to a savings of only $100/year but the range increase makes it temptin. If you can get a couple more panels on it, say some flexible ones on the hood/tail, your time would go down and payback would go up. Probly look like Michael J Fox in a delorian at that point but WTH?
