This solar-powered Solectria Force might be a contraption, but let's see just how practical it might be. Simply eyeballing them, say those panels combined produce 600W peak (dunno what these are, but I would use the highly-efficient SunPower panels in this application). So, let's say if they're properly pointed into the sun they're averaging 400W output over a sunny nine-hour workday (preumably he/she goes out at lunchtime and moves it). That's 3.6kWhr. Say there's a dc-dc converter with a wide input voltage range that feeds the 156V battery pack directly and let's assume a 85% converter efficiency, which means he/she feeds 3kWh into the traction pack during the workday.
If it was feeding my iMiEV which has a lifetime history of 4.2miles/kWh then I'd be getting 12.6 miles daily off these panels. Unfortunately, my iMiEV would no longer be getting 4.2mils/kWhr with all this stuff plastered on it, so that's yet another issue. This whole discussion is aimed at the commuter who has a 40-mile one-way commute in the iMiEV and cannot
recharge at work. This additional 12.6-mile range increase would still not solve the problem, even if the iMiEV's efficiency was unaffected. For that scenario, I would think you'd need to add at least 20 miles additional range if this is going to be a serious commuting solution. Say, nicely-contoured flexible solar panels are employed, their relative inefficiency and surface area still wouldn't solve the problem, IMO. In any case, a cloudy/rainy day would mean you sleep at work that night.
If it was me, I would try really
hard to find a place to simply plug into 120vac while at work. How about working out a deal and parking in back of a nearby gas station?
