Hyundai to offer mid-sized electric trucks in Australia this year, page-74

Dick Smith loves his EVs and has the solar panels and battery storage to recharge his car, he said that all up the cost was much higher than buying and running an ICE vehicle.

Your electric 3t truck would possibly have a 150kwh battery, so if you want to charge your truck from your solar panel and battery system you would need at least 19, 10kwh batteries ( you get 80% of what you put in back out) at a rough cost of $10,000 each and enough solar panels to charge them. (do you have enough roof area?)

How many trucks X how many batteries and solar panels?

It probably would be cheaper to buy your electricity from the mains grid.
