If I have an electric car that gets 80 miles on a full charge,can I expand that ?I thought I put solar panels on roof,connected to inverter that converts to ac,then in the morning when I disconnect from the house, before I leave,I connect the solar panels,to the same receptacle that I disconnected fom house.When I drive off,it would start charging as I am driving,thus giving me more range.It would also charge when I stop at a remote location.Is this possible.thanks dave

that will only extend the range a little, there isnt enough acreage on the car to recharge the batteries quickly. solar car races use extremely light cars specially made for minimum wieght and wind resistance.

I doubt the solar could even start the inverter/charger circuit.

Solar direct to batteries might help a small amount.

Do the math (solar watts or AH) compared to battery power.

if it could give yoou only ten miles,it might just make your round trip possible,a thought,thanks for your input dave

Why incur conversion losses boosting the solar to line voltage, only for the car to convert it back down again to suit the battery!

Just get a bank of cells with enough surfeit for a net charge current and a diode to prevent back leakage when the sun goes in.

Any addition to usual charging you get when the sun shines is a bonus.

Assuming you manage 300W panel. It'll give you 1kW in 4 hours - perhaps 2% of your total charge. Looses because of bad airodynamics will definitlely be more than this.

Because that would potentially void any warrenty.
