On September 25, 2012 Tesla Motors formally announced their Supercharger strategy. Here's the launch video:
During the event, Elon discussed the concept of for free, forever, on sunlight
- For free, forever. Owners of the 85kWh Model S, and owners of the 60 kWh Model S who purchase the Supercharger option are able to use the global network of Superchargers to refuel their cars at no additional cost, forever.
- On sunlight. Over time, the intention is to add solar panels to roofs over the Supercharger stations. Over the course of a year, the total solar power generated will exceed the total power consumed by the cars using the Superchargers.
