But in daily use on real world roads, where it might be cloudy or sunny,
where trees and structures often shade the streets? E, I don't think
so.
And as I showed before, based on the energy consumption and PV output
specifications provided for this vehicle, the claim is just not credible o
The Stella "running system" (lights and such not propulsion) uses 50 watts.
The Stella propulsion system consumes 35wh per km. Pretty good. This could
possibly be done with 4 high efficiency hub motors. Lawrence Rhodes

to 40 mph under bright sunlight. The Stella has an efficiency of 35 wh per km
This may be a relevant adventure story, now 5 years old, about lessons from a
Canadian solar car, which as far as I know still holds the distance record.
Google XOF1, or look at XOF1.com and you’ll find some references. The car
named XOF1 travelled more than 35,000 km in the US and Canada, using on

Do you really mean it's capable of producing 16 kW (about a third of the
motor's peak power), or do you mean 16 kWh?

The Stella uses 35wh per km.weighs388 kg. Has a 16 kw battery. Size is
499x165x115 cm. They fit 1.2 kw of panels laminated into the roof. Stella at
40 mph can still charge the battery. Daytime range is780 km. Night range is
430 km. Still substantial. Engine power 42 kw. You can now see

When I say bicycle I mean chromoly tubing welded space frame. Probably 2
inch. I'll be copying the Stella doors which hinge up. They don't have
wipers. They use water shedding technology. Stella has a round windshield.
Wipers would b a problem. I'm working on it. LR

Being a product development engineer, this strikes me as a HUGE project.
Even if you're not looking for professional results. I sense that you
understand this is not something you'll be able to toss off in a weekend,
but the key issue as I see it is this - how much time and effort will you
need
I have 200W of solar panels on the roof of my Prius. Did it in 2007. THen
realized, why in the world waste time with 15 SqFt of solar panels on the
roof of my car when I have 1500 sqft on the roof of my house!
And, in 2013, the cost of 250W home-roof top panels only cost $200 compared
to the $24
While it sure sounds like a fun project...by far the easiest way to have a
solar-powered car is to leave the panels at home, on the roof of the garage or
home. Unless I'm sorely mistraken, a significant fraction of the EVs owned by
people reading these words are already solar-powered.
