Tesla's calculation comes out to about $200k for equivalent capacity solar plus battery.
Even deducting $25k from that for the cost of the generator and another $10k in required electrical modifications, that would more than double electricity costs (vs the grid) based on 20-yr lifespan and payback, before interest.
