What you described seems to be a net-metered system. You are buying and selling power to the grid. You produced say 10,000 kWh and you bought 10,000 kWh. For a NET energy payment to the utility of zero. The goal of any home solar system.
So that is what net metering is all about. So... What value then is the battery? It adds nothing to that equation other than a fixed $13,000 up front loss that can never be receoverd.? What am I missing? You have described a PowerWall. The battery is one or more units that > will supply or charge 5kw and holds 13-14kwh. If about 11kwh will carry > you over night and if you don't use more than 5kw over night, a single > battery unit will serve you. With good sun, day time self power use can > be around 20kw, including car charging. > > In 5 or so months, I have bought less than 10kwh from my utility and > sold them something like 10,000 kwh. That is with one battery unit. > > Cost installed was about $13k. For smooth operation, I am highly > dependent on the utility to accept my excess power. > > _______________________________________________ > UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub > http://lists.evdl.org/listinfo.cgi/ev-evdl.org > Please discuss EV drag racing at NEDRA ( > http://groups.yahoo.com/group/NEDRA) > > -------------- next part -------------- An HTML attachment was scrubbed...
