The daily cycle battery is designed to cycle...if you leave it fully charged for a long period it will be unhappy. It is meant to be used.
The backup battery is designed to wait. If you cycle it every day it will degrade.
So you need to know what you plan to do with it.

There will be new infrastructure built and jobs created and who knows what the $ tradeoff will be...but it leads in a sustainable direction. Just like Aluminum, Lithium will be cheaper to recycle than mine. Unlike FFs it will still be in there after the battery is dead.

The grid operators have been putting up with this because it put off the day when they would have to site and build new power lines. An expensive regulatory nightmare.

The problem is with the "last mile" power transmission which often involves wooden poles, overloaded transformers, and crappy contractor-installed, barely compliant building wiring, all poorly protected from lightning strikes.
If I was a power company, I'd be all in favor of grid-attached distributed solar, which would make my life less annoying. However those off-grid residences would be worrisome, if your business was generating power (or buying it wholesale) and selling it retail.

Yes, quite correct. However the present regulatory environment is also much more optimal for implementing renewable energies while taking advantage of an uneven playing field.
In my planned move to Wisconsin and my hoped-for newly-constructed passive home, I hope to have Tesla's solar roofing and Powerwall batteries over both house and garage and a wind turbine which will still be charging on cold Winter nights. The house design we have settled on is a distinct style called Early New England saltbox:
Hopefully, the Tesla roofing will be on the larger roof area, facing S, with perhaps more such solar PV on the garage, since I plan to have at least on longer-ranged EV.
The basic idea is a superinsulated home, all electric, off-grid, energy plus design, that requires no hydrocarbons be burned - not even wood - for HVAC or cooking or other systems. I believe that this can be done for a price premium of +35% over simple building-code-compliant home design.
They had the same thought in Spain and Nevada. But it turns out government subsidies were not as stable as some hoped. One day the government decided they were going to cut the gravy train of Solar subsidies. And the Solar industry in Spain & Nevada collapsed as a result.baha wrote:And as far as your neighbors paying for your power, that's as it should be...we are all paying for the effects of burning FFs too.
Spain’s solar industry to collapseOne of the main producers of renewable energy in Europe, Spain’s solar industry, is edging toward bankruptcy. Producers say they’ll be unable to repay credits after the government’s decision to cut subsidies. Banks will suffer and jobs will be lost.
Energy Minister José Manuel Soria has introduced a new compensation plan for calculating levels of "reasonable profitability" for renewable-energy production, distribution and transportation. It will reduce payments to companies serving the nation's electrical system by up to 2.7 billion euro annually. It’s hoped the move could help cope with the electricity system deficit that has been growing since 2005 and now exceeds 25 billion euro.
Experts are warning that with the increased levies on self-consumed solar energy so high many households will have to pay more for the electricity they generate themselves than they would for regular grid power. The main trade association for Spain's electric utilities which distribute most the country's electricity said "the cuts will compel our member companies to undertake a drastic reduction in jobs and review their investments in Spain"
Spain has over 4GW of installed capacity. For several years the government reportedly pushed electricity retailers to pay above-market, unaffordable prices to renewable-power producers. In 2012 clean energy subsidies in Spain hit 8.6 billion euro, nearly 1 percent of GDP. To fund the expansion, Spanish banks lent the solar-energy companies nearly 30 billion euro. Potential loan defaults could worsen the already heavy burden on Spanish banks.
We Were Booming and Now We're Dead" — How Nevada's Solar Industry Bright Spot Turned DarkLouise Helton, owner of One Sun Solar Electric in Las Vegas, says that since January her company is doing more work removing solar panels from rooftops than installing them. “During the recession, rooftop solar was the bright spot in the Nevada economy,” Helton tells DeSmog. “We were booming. And now we’re dead.”
By removing a key incentive for rooftop solar customers — net metering — the PUC made it prohibitively expensive for existing and future solar customers to use solar panels to generate part or all or their electricity needs. And it turned electricity-generating rooftop panels from a net-plus for homeowners to a technological albatross.
“Seniors have tried to make the right decision to preserve their future dollars. All of this is impacting them. Now the value of your greatest asset, a home, and the equity, for solar panels to present themselves as something that was a huge asset, now they’re the opposite. It’s devastating.”
Nevada Hemorrhages Solar Jobs
Since January, national rooftop solar companies SolarCity and Sunrun have stopped seeking new business in the state and laid off hundreds of workers. The few small companies left are trying to stay above water and telling potential customers to be patient and wait out the storm. “My feeling is 80 percent of all (small solar) companies are gone”
