The claim that 1 hour solar charging will get 32km range is… bullshit.

  Looking at their website [1] they claim a 625 km range with a 60 kWh battery (10.4 kWh per 100km) and up to 70 km of additional solar range ("Based on a 35 km workday commute in Southern Spain in spring and summer"). Therefore the solar panels would need to generate additional 7.28 kW of energy. > Most of Spain receives 3.0-3.5 kWh of solar energy per square meter per day, comparable to southern Italy, Greece, Japan and the U.S. states of California and Texas. [2] With a 20% efficiency (0.6 kWh) and 2m² of panels, then in these ideal conditions it would take about 6 hours, which makes the claim somewhat feasible. > Germany receives 0.5-1.0 kWh/square meter/day. [2] So, this gimmick is not really useful for non-ideal conditions.

    That's still being quite optimistic--you're not counting battery losses. I can see a role for solar cells on an EV--keeping it topped up. That's about it, though.

      Absolutely. It's a marketing gimmick, not reality. I think solar cells on EV will be a thing if something like perovskites hit the market. 20% efficiencies for very cheaply printed solar cells, would be a nice add-on if they are basically added for free to the car.

  Maybe you misread? I see a claim of 32km range from 1 hour wall charging, when the vehicle is plugged into a regular home socket, Lightyear 0 can still charge 32 kilometers of range per hour A claim related to solar charging from the article might be the one about the sun sustaining 35km/day for two months.
