When I read this I suspected the power output would be too low for charging.
The interior fan runs at a significantly slower speed when on solar power than on internal power.
Maintenance is a good idea, though 0.65amps isn't much. The CTek maintenance chargers operate at 0.8amps, and like ainarssems said, that kind of amperage will only maintain a battery, it is totally insufficient for charging (unless you have about 6 months to wait, and even then I doubt it'll get you far!).
Even a standard 4amp charger will only get you to about 60% as the batteries internal resistance increases as it charges.
It'll be interesting to see how the maintenance charger mod goes, though as my car spends about 80% of its life in a garage, I'm not sure if it'd be worth while for me!
