No word on that yet. I did see one guy on yelp saying he had his panels cleaned in February, and mentioned ash as one of the reasons.
More generally, figure 3.5 of
globalvolcanomodel.org/wp-content/uploads/2015/08/Global-Volcanic-Hazards-and-Risk-Full-book-low-res.pdf
is a map of the areas of the world which are at risk for >= 1 mm of ashfall from an eruption:

power systems in those areas will want to take extra precautions. Most areas don't have to worry about it much.
But remember, volcanoes can give even fossil-fueled systems a bad day; see e.g.

...... It's interesting stuff; it seems clear they're learning from Hawaii's experience. (See also utilitydive.com/news/solar-has-transformed-into-solar-plus-storage-what-will-net-metering-becom/522893/ for some more thoughts on the subject.)
The rules still need to be approved by the building standards commission, so it's not a done deal yet.
I am all for installing solar or wind because it helps but unless people reduce their consumption and find ways to generate power regardless of the weather conditions most people will find it very hard to get even close to having 100% RE power. The worlds weather and ash belches will hopefully get people to realize their folly of being too dependent on RE.Leave a comment:

Yes, real time pricing would get things moving in the right direction! It's painful for some users, though. California's approaching this slowly, and has been phasing in a rough approximation to it (TOU pricing) for some time.

My impression is that California's realizing that, if your goal is to reduce carbon emissions, adding solar by itself becomes less and less useful as the grid becomes saturated with it; to be useful, it needs to be coupled with other measures like load shifting, peak shaving, and time-of-use pricing.
The rules approved today by the energy commission ( utilitydive.com/news/california-to-require-rooftop-solar-for-most-new-homes/523200/ ) would require solar on many new buildings, but also encourage storage, particularly storage that is responsive to TOU pricing and other utility signals. For details, see energy.ca.gov/title24/2019standards/rulemaking/documents, click on "2019 Reference Appendices"; appendix 11 is about PV requirements, appendix 12 is about storage. It's interesting stuff; it seems clear they're learning from Hawaii's experience.

But the bigger picture is - they're part of the folks that are convinced that humans aren't causing climate change, and posting any science on the topic - or any news related to reducing greenhouse gas emissions - triggers them pretty hard. The forum's current owner appears to agree with them, too.
The other side of the equation is that SK and JPM are genuinely helpful people, with strong technical skills, and that's very valuable to the forum.
The upshot is, they get a pass for behavior that would get them kicked off quickly on less polarized forums.
Anyway, they've been gunning for me for some time, and seem to attack anything I say, no matter how neutral, factual, or careful it is. C'est la vie.Leave a comment:

Ok , I did do some research on him before I posted and saw him post and then get ripped and he stayed civil and did not give it back to you guys so I felt sorry for the guy but I will do some more digging and just see want he said that was so wrong.Leave a comment:

Sunking How about we educate people the best we can and not call them names ( idiot ) and try to get them banned ( aren't you banned yet ) when they don't agree with us or don't tow the line we demand ? or is that to hard for you to use some self control ? People are going to disagree from time to time .
I mean I wouldn't want Dan to start calling you SunQueen everytime he didn't like something you said, lol
More not that anyone cares: IMO only, that's rude, inconsiderate, selfish and unacceptable behavior. I go after Dan's antics for those reasons. Like a child who gets scolded for inappropriate behavior, Dan thinks I don't like him for calling out what I see as his often inappropriate and likely harmful behavior. Reality is, and facts are, seems like I've always known someone before I would like/dislike them. Dan and I have never met. But, I think I know B.S. when I smell it and Dan's posts often have a familiar scent to them. I sort of think it's kind of a public service to call B.S. on Dan's spoor when I think I see it. Other's do the same for their own motivations. In that respect, I believe I'm in good company.
As for Dan's motivation, not that anyone cares, but my guess is that Dan is a "me-too" wanna be of R.E. of the "you could just and simply do this and the world would be better" school that doesn't take time to understand the details (where the devil seems to often reside) but wants to play with the big dogs.
But, since this is a place to exchange information and opinion, Dan seems to think and act as if he's free to abuse the privilege. Other's are just as free to call B.S. on his stuff as they see the need, public service or otherwise.Leave a comment:

I tried it your way, does not work. Many people have tried. He comes back once in a while, throw his propaganda out to see if we are still looking out for him. He likes being kicked.Leave a comment:

Bruce shut up. Dan and solar supporters do not want the public to know what reality is. It is not Politically Correct to speak truth and facts. You should know better, The public has been brainwashed and educating people would destroy all that hard work. Think of how long and how much work it took to make Dan an idiot?
I mean I wouldn't want Dan to start calling you SunQueen everytime he didn't like something you said, lol

So NET ZERO is going obsolete? I don't see what replaces it, people are still going to have lights
on at night and the AC. And no 3KWH battery is going to solve that problem, nor will battery
problems be accepted by the public.
Here in northern IL have been net zero for years, but it would not work if every customer did it.
Collect energy in the summer, use it up in winter. Its a huge problem for the PoCo, but I hope they
are working hard on it. Bruce Roe

Along those lines, it's interesting that electric meter maker Itron and storage vendor Sonnen announced a partnership recently. Some towns already require solar on new houses; requiring 4kwh of storage as well, and using it to reduce peak system load to avoid adding peakers, may well be in the cards someday.

Solar would be included with new homes just like a water heater and central air conditioning .Last edited by Kingram; 05-04-2018, 07:07 PM.Leave a comment:

Tesla already raised their Powerwall 2 price $400 two weeks ago-
Just as we start seeing more Powerwall deployment from Tesla, the company slightly increases the price of the home battery...
So what is your opinion on the incentives azDave ? I wonder if APS will follow suit.Last edited by Kingram; 05-04-2018, 02:54 PM.Leave a comment:

Sigh....My POCO just began offering up to $1800 in incentives to install a battery storage system.
