Again, I personally don’t think it’s practical. Maybe Scout is quirky enough to attempt it. However, at an estimated 120-130 kWh battery pack for full EV versions, even a perfectly oriented panel on the bed would literally take months to charge that HV battery pack. It’s not easily marketable...
Solar panels just aren’t efficient enough for that yet. Even the best sit around 20-25%. The surface area is just too small and would only yield around 200-250w. Efficiency in EVs is measured in miles per kilowatt. 10 times more than what it might generate in a day.
Look at the Hyundai Santa Fe...
