1/2 charge on a summer's day. So less if it's cloudy and less if it's winter. Maybe a lot less, maybe 40%. A 1/2 charge seems to be about 1.2kwh. The EVT is rated at 1.5kw. So you might get an hour out of that. Anything more powerful (a typical scooter will be 5-10kw) and you're taking 20,30 minutes a day - with ideal sun. So, if anything, my previous math was conservative. Anyway - I'm not disagreeing with the principle - just saying I think there are better ways of going about it... I'd say, just stick with the plug-in and put the solar panels on your house.
