Tesla wouldn't put a solar roof on Model Y so this owner did it himself

A Tesla Model Y owner got fed up with the company not offering solar panels for its cars, so he built one himself.

Reddit user somid3 shared his project, dubbed Beta One, last week (via Electrek). It's a deployable solar roof that weighs less than 165 lbs and can retract when the car is in motion. When expanded, the project's website claims, it fits in a standard parking spot and generates "100 percent clean and net-positive power from the sun."

But what about the range you actually get from this thing? The website claims that, using nine 175-watt solar panels, Beta One can add 6kWh to the EV per day, which is about 20 miles of range, with five hours of sun. It's unclear whether the range estimate accounts for the added weight. The website also claims that the solar panels are "easy to assemble," and that they can be carried "on all EV rooftops, including Teslas."

While the project's website even has a target price estimate of $4,000, the design still in a fairly early stage. In fact, somid3 claims he already has an upgraded, "Beta Two" version in the works, with reduced drag and sleeker profile.

Some EV manufacturers do offer a solar roof as option. This includes Toyota's new Prius Prime plug-in hybrid and the company's bZ4X EV, and Fisker Ocean.

As for Tesla, the company did promise that Cybertruck will have a solar roof option, but it's not available at this time, so the only option for owners who want more independence from chargers is a do-it-yourself solution of some sort.
