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.

- LorenPechtel 4y agoThat'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.
- V__ 4y agoAbsolutely. 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.
