i totally like the idea of charging the battery
during LOW usage times like at 3:am
then during Peak usage hours your running off the battery
instead of off the electric companies line ....(more $$)
i agree that there's so many questions like how LONG
before i get a return off my investment.
With new changes to layered Graphene sandwiched solar cells "almost daily"
(making them charge much faster) this technology will be a rapidly
changing scenario no matter What Elon Musk comes up with.
