Omid Sadeghpour built an expanding solar roof array, called Beta1, for his Tesla Model Y that provides up to 75 miles of additional range under optimal conditions. This prototype weighs less than 165-pounds and generates 6 kWh of power to the battery per day via DC-to-AC-to-DC charging.
The wood-framed Beta 1 prototype was built in collaboration of Jeran Bruce at California’s Forged Makerspace. It sports telescoping carbon-fiber tubes that can fit nine 175-W flexible panels, which fold out when the vehicle is parked. There’s no word yet on if we’ll see a production model.

Overall it has been a fun project so far and I am designing Beta2. Beta1 is 11 inches high and is made out of wood. Beta2 will be fully made of carbon fiber and will be 6 inches high. Right now I researching the DC-to-DC charging and hot wiring,” said Sadeghpour.
