SOLAR POWER

Does anyone have any thoughts about solar roadways?

(Is there a separate thread where it's being discussed?)

fuckin Nevada, it blows my mind

thanks to WmC for the link

http://www.vox.com/2016/1/20/10793732/nevada-solar-industry-explained

not sure what can be done at this point, the brazen bait-and-switch move here is just insane

yeah this is ridiculous and will bite them in the ass

they're not the only states where investor-owned utilities are trying to roll back net-energy-metering - distributed generation systems are basically a death knell for the traditional utility distribution system model

awful

but no fear, the Republican Party is almost dead

PUC is caving on the retroactive issue, hopefully:

there's no way this entire debacle doesn't get reversed at some pt imo - either because of lawsuits or political pressure

boo

I haven't posted or even been on ILX for a long time but this seems like a good time to decloak.

Naturally net-metering is important but providing parity payment is unsustainable and although the way it was handled in Nevada was utterly boneheaded it probably had to go in time. My understanding was that NV provided no-sunset for parity net metering payments and rather than closing the scheme for new installs pulled the rug from under existing owners. In a market with so many PPAs and people having bought into sola under assumptions of payback over time that was plain wrong.

Over here in Australia we've had all kinds of incentive scheme from Carbo based credits, generous (66c/kWh) and less generous gross metering, and net metering. Currently every new customer gets the carbon credit (Renewable Energy Target) up front and a net metering create of ~5c/kWh for the avoided wholesale cost of electricity. There is no credit for the avoided transmission and distribution costs and the benefit that that solar offers the network is not compensated for - that said the extra costs that solar customers (and those with big A/Cs and pools) impose not he network are not fairly distributed either.

All of this is leading to much more generous pricing and compensation models. We've had a regulatory process (called Power of Choice) which is leading to more cost reflective network pricing (Residential Demand Charges and or Time of Use) which will penalise A/C use and reduce the self-consumption benefit of solar (without storage). Further off It something I've been working on if the Local Generation Network Credit which is a proposed mechanism for compensating distributed generator owners for the value they do offer the network. It will go some way to recognise that solar on a residential zone sub at 2pm is not very useful but at 4pm it is very useful. There's a good description of the way it works in other jurisdictions in the briefing paper for one of the workshops I've been involved in.

The TL;DR on this: this shit is complicated

thanks, gonna dig into that when I have time.

I am sympathetic to the "costs of distribution" argument in terms of reforming net metering, but as you note the retroactive penalty was where the PUC really fucked up in NV.

CA PUC smarter than NV PUC:

great news

congress looking into some pre-emptive legislation forbidding retroactive net metering changes:

Hope that passes, good on them. Murkowski being in charge is of course disgusting and counterproductive.

Ah but when everyone has a telsa powerwall the grid will no longer be of any concern!

incorrect, those batteries don't store enough power to run a house, the stored power is used for peak shaving and load reduction

they also quietly discontinued the larger model last week:

cuz guess what? they are just too expensive.

sad lol

someone really needs to crack this battery storage issue

i'm probably going to do a solar lease. I know this doesn't give me the tax benefits purchase would do, but I already owe the IRS money so on a monthly basis leasing saves me more. I'm guessing that CA already worked out the issues that are plaguing NV and ruining the industry for them over there.

recent CA PUC ruling preserving net metering is posted upthread

oddly I JUST NOW got a CREDO email saying that they are challenging that. Fuckers.

so not gonna happen

good range of comments on that article

Galatians! lol

the key is to convert solar power to heated magma to be used later!

Well that's neat

more trade war details for anyone who is interested

https://www.greentechmedia.com/articles/read/suniva-solarworld-file-new-trade-remedy-proposals#gs.96pEz6E

as I mentioned in the Global Warming thread, one of the big problems with all of this is that four years isn't a long enough window to actually build cell factories if the tariffs that make them cost-effective disappear after that point.

Circa 1980 I bought a Casio solar-powered calculator, just the kind that does basic arithmetic operations. It has only just now bit the dust, after providing me with 37 years of faithful service and not a single battery required, let alone daily recharging. It was perfection of its kind. Of course, with mobile phones now performing the same functions, I will never be able to replace it.

Ha! I have such a Casio, bought at about the same time, and it's still working fine.

Mine was dropped once too often.

waiting for the penny to drop on Monday w/r/t tariffs or cell quotas

this speech does not bode well:

http://www.smh.com.au/world/us-will-no-longer-be-taken-advantage-of-on-trade-trumps-sharp-rebuke-to-china-20171110-gzj60v.html

idk that reads like his usual empty bluster

and nothing specific about the solar tariff issue

I know, I'm just paranoid.

The ITC recommended like four different options, nobody has any idea what's going to happen and it's the uncertainty that's wearing on me

60 more days of misery, uncertainly, market disruption, and fear. This is the worst.

https://pv-magazine-usa.com/2017/11/13/the-clock-ticks-itc-turns-section-201-over-to-president-trump/

pv magazine staff has found no sources that can tell us more about this confidential report, and ITC staff has stated that a public version will be released at an unspecified later date. {...}

In other words, President Trump can do just about anything. There are precious few limitations, but these include that initial trade action can last four years (and be extended to up to eight years), and that tariffs are limited to 50% of the price of products “above the rate existing before the proclamation of action”.

This last detail may be more complex than it first appears. While all the commissioners who recommended import duties would have the tariff values calculated on the cost when solar products enter the nation, SolarWorld and Suniva have asked for duties equal to 50% of the prices during timeframes covering previous years when solar cells and modules were much more expensive.

Neither SolarWorld nor Suniva has done much to mitigate these proposals, which we at pv magazine feel are dangerous and unreasonable.

"uncertainty"

dumbfucks

both of those companies can burn in hell, forever

so selfish and stupid

yeah it's rather remarkable

Other solar groups have stepped up to support the cause using social and advertising campaigns. A coalition of manufacturers, U.S. Made Solar, has been running TV advertisements during shows that President Trump watches regularly, such as Fox & Friends.

we'll know within two weeks, probably. good article.

30% tariff, could have been worse, hopefully Solar World and Suniva die now

well looks like Solar World found a way out

Anyone here have experience getting solar at home? I've been intrigued for years, but the numbers seem completely unappetizing. When I put our address into the supposedly close to accurate free google solar calculator, for example (https://www.google.com/get/sunroof), it claims savings of $6000 over *20 years*. $300 a year for two decades seems a pretty paltry reward for putting five-figures into the system, even with (dwindling) tax write-offs and rebates. And yeah, floating somewhere in there is environmental impact, but on that front it seems much more efficient/easy to just find ways to use less power, or if you're feeling generous just donating that huge amount of upfront install cost to a food pantry or something, where every dollar given gets exponential returns.

I dunno. Am I looking at this all wrong?

(caveats: i don't own a home, and i haven't payed close attention to this stuff for a while)

i think you're generally looking at it in a reasonable way. a couple thoughts:

- solar panels are getting less expensive and are a lot cheaper than they used to be, but they still typically have long payback periods (the amount of time it takes to recoup the upfront cost) for individual homeowners.
- some utilities have amazing financing programs where they'll pay quite a bit of the upfront costs and gradually bill it to you on your utility statement every month. some don't.
- in general, solar is much more economical at scale. at some point if we don't have the dumbest person of all time as our president, maybe we'll upgrade our grid and energy policies so that individual homeowners with solar can even feed excess energy INTO the grid and make a little money. but instead we live in this world.
- you're spot on, i think, about looking for other ways to use less power and using that money for something else right now. you can get a free home energy audit (disclosure: i work in this field) from your utility that will identify energy saving measures, and in a lot of cases the utility will even install free equipment (smart thermostats, energy-saving aerators for faucets, etc). energy efficiency measures typically have a MUCH shorter payback period than solar panels on a roof.

oops, my link was broken. i meant to link to an image of concentrated solar power:

https://news.energysage.com/wp-content/uploads/2018/11/11.14.18_solar.jpg

curious to hear from people from other non-chicago places though! like i said, i haven't followed it closely in a while and it's possible that people in warm sunny progressive places are able to take advantage of residential solar in a more cost-efficient manner

federalism, baby

Good primer article (with video) on balcony solar systems... I have a south facing front window where this could really work

https://www.theguardian.com/environment/2026/may/27/balcony-solar-panels-rising-utility-costs

I've been back at work for two days and have had two people ask me about this (Utah residents). Everything seems to be selling out instantly, I have not heard back from the distributor (EcoFlow) as to availability, their site says sold out. I still don't see the APsystems I linked above for sale anywhere either.

What happens to old solar panels when they stop working, can they be recycled or do they just go to the landfill?

My understanding is that the metal frame parts can be, but the collector wafer part can't.

I would say AliExpress but who knows if they ship to the US at reasonable rates anymore.
