In a Friday tweet, Musk revealed that the Cybertruck is getting “an option to add solar power that generates 15 miles per day, possibly more.”

Will be an option to add solar power that generates 15 miles per day, possibly more. Would love this to be self-powered. Adding fold out solar wings would generate 30 to 40 miles per day. Avg miles per day in US is 30. — Elon Musk (@elonmusk) November 22, 2019

Solar charging could be a nice way for Tesla to make Cybertrucks more profitable. Tesla customers commonly opt for extras like “full-self driving” abilities and specific colors that plump up the price tag.

Tesla’s Cybertruck is a vehicle that has been a long time coming. By providing the Cybertruck with a way to generate power on its own, the addition of a built-in solar panel system into the pickup would enable the vehicle to gain more range as it stays parked in an outdoor spot.

Such a system could even be useful for homeowners whose Cybertrucks will be parked at the driveway, where the vehicles will likely be exposed to the sun on a regular basis.
