The company promises that this model will not be sold to the public, thus guaranteeing exclusivity (and probably some future availability at a premium on ebay).
The new look of the Tesla Powerwall 2.0
The standard issue Powerwall 2.0 is valued at $5,500, and to add to that value, winners receive the energy storage system signed by CEO Elon Musk, CTO JB Straubel, and Design Chief Franz von Holzhausen.
Says Tesla in a letter to owners:
"We've made some exciting updates to our referral program awards. Owners with 7 or more qualifying referrals will receive an exclusive red Founders Series Powerwall 2.0, hand signed by Elon Musk, JB Straubel, and Franz von Holzhausen. This award is not available for purchase. Just share your personal code with friends, family, or anyone else. They can use the code to get a $1,000 credit towards a new Model S or X until January 15, 2017."
