If it costs $5 to charge an electric vehicle during the day and $2 to charge it overnight then a lot of that charging will in practice be done during the day. As such, electric vehicles won't contribute as much to load leveling on the grid as many assume - sure there will be some off-peak charging but there will be some additional peak load as well.![]()
I see ford has a proposal to get around this by proposing a new car with solar PV built in on top. What's interesting is their use of fresnel lenses in a canopy that concentrates the sun onto the solar panels. They believe they'll be able to use solar for roughly 75% of all travel, and the car has a small petrol engine for range extension which should discourage panic recharging. Seems the car automatically moves itself when under the canopy to ensure it's receiving the maximum level of light on the built in PV.
I'm wondering it it would be possible to use the same fresnel canopy to increase currently installed home solar PV?? Depending on the cost if it could increase production enough to provide a 3 year ROI it might be popular, especially since in theory it shouldn't run afoul of any of the current Govt programs.
* Fresnel lenses are like those used in light houses.
