Erweiterbarer Solar-Dachträger bietet 1 kW netzunabhängiges Laden für Elektrofahrzeuge für 3.000 US-Dollar. Fügt 10–20 Meilen pro Tag hinzu

>LA-based startup DartSolar said its electric vehicle roof rack attachment adds 10 to 20 miles of additional range per day.

>The roof rack adds 360 W of solar capacity when stowed for driving and can expand to 1000 W in a folded-out 1 kW array. The low-profile solar rack stands 1.5 inches tall and can expand in 15 seconds.

>The unit is currently priced at $2,950. DartSolar said with a ten-year lifespan the product has an expected payback period of two years and a 5x return on investment.

>“With advancements in tandem solar cell technology by companies like Kaneka Corporation and Oxford PV, DartSolar is currently designing a 3,000-watt solar roof rack capable of providing 30 to 40 miles of charge per day,” said DartSolar.

It won’t replace grid chargers, but since [93% of car trips are under 30 miles](https://www.energy.gov/eere/vehicles/articles/fotw-1230-march-21-2022-more-half-all-daily-trips-were-less-three-miles-2021), 10-20 miles is useful.

Seems like it would be valuable in an emergency but nobody’s putting those stupid looking panels on their car semi-permanently. Not for $3K at least.
