3200 watts is only 4hp; presumably the motor is a lot more powerful than that so the thing will spend more time charging its batteries in the sun than it does actually moving.
Isn’t North Korea prone to not having sunny days?
That’s 3200 watt/hours under ideal solar conditions.
My LEAF takes about 8 hours to charge at that rate, a car that can more 4 passengers and cargo about 80 miles under normal driving.
Straining math, capacity, and credulity, we could suppose that bus somehow requires 10x those power requirements to haul 140 passengers under flat straight and slow conditions.
That’s at least 10 days of charging, assuming ideal weather and panel orientation... And I notice those panels don’t look like they can be moved at all.
My experience with solar is that actual performance is much worse than advertised, so I expect that bus will need to sit in the sun for a full month to charge enough for just a few hours of operation.
What do you suppose the payoff time is on those panels? 30 years?
And that’s peak power. They’d be lucky to get half of that on a regular basis.
