Tesla consistently rolls out software updates, and the latest has brought several new features to the fray, including a "Charge on Solar" function that lets owners charge using only renewable energy. By using this, your Tesla - be it a Model 3, Model Y, or one of the larger vehicles - can charge using excess energy produced by Tesla's solar system. Unfortunately, 2012-2020 Model S and 2015-2020 Model X vehicles are incompatible.
Here's how it works. Setting it up is easy enough. Select your vehicle in the Tesla app, and tap "Charge in Solar."
