I know someone in California who this month was quoted $5,500 for a Powerwall 2 plus $1,000 installation, this was as part of a solar system quote from SolarCity.
So Powerwall 2 pricing is "out".
3 kwp means you are going to self consume your entire production, so what is the point of adding a battery? If you could put in say 10kwp using higher capacity panels from lg or sunpower, then you may be on to something with an added battery.I have a recent quote from Natural Solar for a 3kwp system with the powerwall 2 starting at $16,670. This includes a introductory discount of $2990 if you are included in the first shipment of power walls for 2017. The price isn't broken down though it includes the government rebate on the system.
What is your unit price, Gary?All true, but if the price of a unit rises the game changes and I wouldn't mind betting that in Qld where power retailers seem to be intent on running themselves out of business it might be a "go-er" quite soon. Price of powerwall 2 will drop as the competition hots up too. I'd be waiting a year to see what pops up.
Yeah, well USD5500 is going to mean $7000 plus shipping, marine insurance and transport within Australia. My guess? Around $10000. Plus fitting! You REALLY need a large excess of production over consumption to justify it and bear in mind the payback time. One unit at approx .20c (from Powershop) in Sydney means about $6 a day. Saved using the battery. $10000\6 = just over 4.5 years. You will be ahead after that.
I put in solar with the .60 rebate. That was the only thing that made it justifiable. My 6 kw system is basically paid off in consequence. Unless both panels and batteries come down drastically in price, it can't really be justified to put in a new system now, unless your supply is relatively unreliable like in SA, or in the bush. There what you are doing is not saving money but guaranteeing an electricity supply. Different ball game.

If you intend to dedicate your entire production as fuel for the Tesla, that may well work.
