I love this idea. We've just seen that a solar powered plane can fly around the world so integrating PV into other vehicles is great. As the vast majority of the driving we do is generally short trips to work and back home this is a great opportunity to travel for free. Obviously in the UK there will be certain days when sufficient solar charging isn't possible but then you can always plug in like a regular EV.
Launched amid much fanfare in Beijing over the weekend, the four prototype Hanergy Solar cars feature varying quantities of the company’s flexible thin-film solar cells – which boast a conversion rate of 31.6 per cent – and lithium-ion battery systems allowing for 350km of range. Among the company’s claims, Hanergy says that five to six hours of sunlight should allow the cars’ thin-film solar cells to generate between 8-10kWh of power a day, allowing the car to travel about 80km on solar power alone.
