California is finally doing something right.Wether you like it or not, renewable fuels is will kill fossil fuels for ever. By 2030 solar power will be almost free. The great savings from almost free fuel will result in a gigantic boost in living standards the world over. The future is good. Just wait and see.

You also get a tax write off because your half price electricity cost is now factored into the mortgage.
So, with projected performance/economic advances in power storage (batteries, supercapacitors, etc.) yes...one could generate most if not all the energy one uses at the residential level. But making money selling excess to the utilities, that's going to be a goose that won't keep on giving.
But this is OK. It will just be the market saying "OK, we're good on electricity."When the price gets that low, we collectively will sell to other states. Then, like I mentioned above, we won't even need electric meters. Everyone will just pay $10 a month for tapping in.
Also, it is ONLY affordable when you consider the feed-in-tariffs that the utilities are forced to buy your power at. But paying retail for wholesale power is economically unsustainable. Not to mention that the grid is not set up for this after roof-top solar gets to around 11% or so feed-in-tariff saturation.
You DO KNOW, right...that the State forces the utilities to pay solar roof homeowners RETAIL prices for their juice, right? Please explain how that is economically sustainable?
Nobody has said the punchline yet. New solar installs will be put on Time of Use metering schedules by 2020. Peak rates are from 4-9pm
Also, don’t buy a Powerwall, it doesn’t make financial sense.
Does it make sense in places like Pacifica, Humboldt and Mendocino counties where there is very little sun?
The day will come when energy storage will be dirt cheap.

Satoshi_Nakamoto sayslostand confused saysDoes it make sense in places like Pacifica, Humboldt and Mendocino counties where there is very little sun?Pacifica is quite sunny in winter.Yeah but does it make sense for non sunny climates? Bakersfield or Phoenix yup. But where I live, we get a few months of sun at most.
You obviously didn't follow the links. Under SGIP, the first 10 kWh receive a $400/kWh incentive, and the remaining 3.2 kWh are eligible for a $200/kWh incentive, worth a total of $4,640. That’s enough to cover almost the entire cost of purchasing the Powerwall equipment, which is priced at $5,500. Incentives have fallen to $350/kWh, but are still quite generous when combined with the federal rebates. Plus you'll be the only guy with electricity on your block after the Big One hits.
Yet. The day will come when energy storage will be dirt cheap. At that point even utilities will be doomed. Imagine one day taking your 1000 KW powerwall the size of a laptop to Walmart for a quick charge.

Imagine one day taking your 1000 KW powerwall the size of a laptop to Walmart for a quick charge.This is the key point. Yes, I do agree that one day soon, completely off-grid will be cost effective, even dirt cheap, but also consider that the grid could become dirt cheap as well. Consider places where already a surplus of electricity makes the price go negative. I believe grid tied will become a $10 a month charge for as much as you want.
The grid costs a lot in overheads, maintenance of the power lines, billing etc. Even if the wholesale cost of electricity was to go to zero, these costs would still remain and go even higher, because wages etc keep going higher. We are a long way from utilities being outdated, but when it happens, it happens suddenly. Look how quickly Kodak, an American icon collapsed when digital cameras arrived. Even oil companies will be obsolete because there is no way they can compete with roof top solar power at 9 cents/kwh, which equates to 3 cents per mile to drive an electric car. Elon Musk will go down in history as the entrepreneur who single handedly destroyed the multi trillion dollar oil industry.Those who drive electric cars like you, see the astonishing value. I'm surprised at the stiff opposition to electric cars and renewable energy by Church goers. Fucking stupid.
Total cost (approximate) $2,710 to $4,810
Malcolm, thanks for the maths!So $3k might not be too bad for battery backup piece of mind, plus you can your program your Powerwall to supply electricity during peak rates. Using PG&E EV rate schedule A, peak rate is $.21 /kWhr higher during summer (6 months) and $.12/kWhr higher the rest of the yearDischarge battery during Peak rates (~5 kWhrs to maintain SOC) .$.22 x 5kWhr x 182 days = $200.20$.12 x 5kWhr x 183 days = $109.8--------------------------------------------Savings per year = $310Payback in 10 years (battery warranty is for 10 years as well).
But this feel-good change to the building code is a questionable public policy for cutting greenhouse-gas emissions. The big problem with the California Energy Commission’s new mandate—which passed on May 9 and goes into effect in 2020—is cost. . .In fact, residential solar systems cost between 12.9 and 16.7 cents per kilowatt-hour averaged over their lifetime, according to a National Renewable Energy Laboratory report last year. That’s more than double the cost of utility-scale solar systems, which range from 4.4 to 6.6 cents. . .
