I enjoy coming home each night to my comfy house, and plugging in my electric car:
sphotos-b.xx.fbcdn.net

After I plug in, I check the output on the rooftop solar panels for the day - this evening it was 23 kWh. I'll always double check the voltage of the house battery bank, which are always topped off. Sometimes I'll pop out and see how much the net-meter spun backwards . . . it worked today to have an excess of 15 kwh. Figuring that my car gets 4 miles to the kWh, and I drive 25 miles, the car will take about 7 kWh to fully recharge. That leaves me with ~8 kWh of excess electricity before morning. With a highly efficient, all electric house, that won't be a problem.

Today will be a fully net-solar powered day. I don't buy any gasoline, and I send back excess power during peak loading times for the grid. Power outages are a thing of the past for me. If I wanted to, I could live without the utility. I'm no longer beholden to a corporation to live a comfortable and modern lifestyle.

I can't wait for the day when I can tie my electric car into my current inverter & battery arrangement. With the LEAF as a 24 kWh back-up battery, backing up my house batteries, it could run my home for about 3 days before I would need to fire up the generator for a few hours to recharge everything.

I enjoy coming home to a fully powered home each night, even during power outages. I never worry about the food going bad in my fridge and freezers during an outage. And my garage door always works.

Rambino: A nuclear power plant "lasts" exactly one minute after the workers depart.  They cannot (or at least should not and do not) operate without human oversight 24/7.  A basic PV system is completely fire-and-forget.


As someone who works in nuclear power...
s21.postimg.org
Run that by me again?
The workers don't leave their posts. Nuclear plants work on rotating shifts. The plants are always manned, 24/7/365. Hell, the control rooms will maintain the plant without human interaction if they could. A lot of the "auto" systems are left "off" so the operators HAVE to interact and know what the hell is going on without the systems caring for itself.
Either way it's a lot longer than "one minute". What you're talking about is "time to boil", usually for coolant water in the fuel pool (or open primary system during a refuel but that's another thing). Time to boil is greatly dependent on when the last refuel is, blah blah blah. It's usually a farkton long time actually, in the number of weeks, as automated systems will run as long as there's some kind of power.
Or are you saying, like, zombie apocalypse..? In which case why are we having this conversation?


Yes, the inverters tend to blow after a decade. So I amend my statement to note that you have to make a trip to the inverter store once a decade. Otherwise, they generally keep on plugging a whole lot longer than 30 years.  Most importantly, the expensive part (the solar panels) have the longest life.  The stuff that wears out is easy to replace.

Birdshiat? Dirt?  Who cares. Yes, your production goes down, but it Will.Not.Stop.

Hail and storms?  Solar panels are a lot more weather-resistant t ...


Oh, and they're poisonous. Let's not forget. They're toxic, they degrade to poisons, and they can't support base load. Good for reducing peak load, though.

Naaa, that's no fun. I rather enjoy the idea that I'm some sort of bot, or astroturfer - as part of some ultimate ploy to lure unsuspecting internet viewers into believing that solar power works, by quickly Googling things.

That's been my nefarious plan all along, since I created my fark account 10+ years ago.

And don't even get me started on the faked national small business EPA award I got a couple years ago, which included one of the first building integrated server waste heat recyclers (a design I came up with).

You have no idea just how deep the rabbit hole goes.

Now excuse me while I get to work on my next project to be falsified, an eco-tourist beachfront resort on the Caribbean Island of Roatan. Which shoehorns nicely with my recently renovated, but falsified, low impact beachfront resort in Maui - most recently featured in Feb's Sunset Magazine as one of the nation's top weekend getaway spots.

Rent Party: Just out of curiosity*, and outside the cost of the car, what were your total install costs for that system? And how big is your house, and where do you live?

/ Genuinely curious.


The upfront cost of the system was $26,000. That included 3.8kw of array, grid-tie inverter w/ battery backup, new breaker panel and sub panel, and a gas generator tie. Permits and installation included. All of the components used are locally sourced, so that raised the cost considerably, along with the fairly involved install with several forms of backup power.

Had I gone with a plain-Jane grid tie with out of state or foreign panels, the cost would have been about half.

It is a 1,000 Sq.ft. all-electric house w/ a 480 Sq.ft shop, near Tacoma WA.

I got 30% of that back on my taxes, so the IRS cut me a check for ~$8,000 last month. The Washington State production incentive pays me for my output, cutting a check every August for ~$2,400, through the year 2020. Plus I save a couple hundred a year in utilities. Compared to driving my 20mpg truck, I save a couple grand on gasoline too.

My basic ROI is about 6.5 years. Every day after that is just pure sweet, sweet profit.

Summercat: Hi Ringy :3

I still want to print your comic. I even know a guy who does damn fine work, and he might give ya a discount on it n.n


Come at me bro! I'm considering redoing the whole thing this summer, regimenting the panels and text lines, refining the phrasing, and adding a section about radiation vs contamination. I'm considering going to Kickstarter or something over it, actually.

js530:
I'm glad you have the technical background to label what an "extreme case" is. Solar makes no sense at any scale, now and into the foreseeable future. Physically, you have separated energy collection to an immensely low density. This will not change. The physical plant for solar will always be physically large and distributed. This means expensive. Until you can grow a crop of solar cells using agriculture tools (hmm..sounds like biofuels. how well does that work?), you will simply not be able to competitively generate power. Panel prices are falling because the governments of the world (US and China) hand out massive subsidies and because there is a huge manufacturing capacity excess. For the money wasted on solar, we could build several nuclear plants per year (2/year in US alone).

Treehugger also had an article recently showing that ALL (net?) new capacity added in the last year was solar power.

I'm not sure how that was calculated but you'd expect there to be a big leap as solar power and other energy sources start to climb the s-shaped curve that coal, then oil and finally natural gas have climbed before them. We have reached the end of the beginning and are now at the stage where the curve will turn sharply upwards.

About time. But each new energy source moves more swiftly (as R&D and scaling-up times shrink rapidly). The USA was still burning mostly wood in 1848 (the UK, Belgium, bits of France and Germany wer already well into the Industrial Revolution but the US and the British lion cubs were just waking up). Kerosene was invented in 1846 by Dr. Abraham Gesner in the small coal fields of Albert Co., New Brunswick, Canada. It is still used as a fuel in jets and rockets. Gesner went on to work as a geologist in the oil fields of Pennsylvania, the leading US producer of oil at the time.

For large-scale power production, big mirrors are still more important than small solar panels.

I'm guessing that the Pennsylvania is big in production because Pittsburg and Philadelphia have re-tooled as post-modern post-coal and iron manufacturing centers, while the U of Penn is probably a center of R&D.

It's PPPs. No, not Public Private Partnerships. Well, yes, it's that, too. But Pittsburgh, Philadelphia and Penn State are probably the places to look for your answer.

Hollie Maea: Martian_Astronomer: Hollie Maea: I should clarify that the actual manufacture of silicon cells does contain plenty of nasty acids.  But the nice thing about acid is that after you use them they aren't nasty any more.

If you like having bones, respect the HF.

Yeah that's the scariest stuff we have (well there is some silane gas I would prefer not to light on fire). The floor is covered with calcium gluconate stations.  But we have not had any HF incidents in the years I have been there.  We are pretty careful with that stuff.


In addition to the economic issues inherent in a small startup, another one of the reasons I got out of the particular niche I was in was the fact that I had to work on R&D equipment with Silane, Germane, Arsine, and Phosphine, and I was reluctant to accept the drop in life expectancy inherent in working with those materials on a long timescale. Whenever the fire department came to our lab, I was one of the people who had to put on the air tanks to go in and tell the firemen it was safe to come inside, and I also didn't particularly like working with phosphorous-heavy residue that caught on fire on a weekly basis and spewed arsenic-laced smoke into the room.

Being an EE in the semiconductor industry is both fascinating and hazardous. There are parts of me that really miss it, and parts of me that really, really don't.

maxheck: Rambino:

Incontinent_dog_and_monkey_rodeo: The thing about nuclear vs solar is that nuclear takes 8 years to build, even after you get all the permitting taken care of. That's a huge investment of capital for a damn long time before you see a return. With solar, once the permits are in place you're generating electricity within 3 months, very little time to tie up dead money before some cash starts coming back in.

Also, you don't need a billion dollars to throw up some solar panels. Downward scalability is a pretty big deal.

That's why utilities love grid-tie systems. If enough people install them, they can avoid the stranded costs of having to build a half-billion dollar gas plant that only gets spun up during business and air-conditioning hours.

Every time I fly I look down and see huge warehouses and big-box stores and the sort of buildings with literal acres of flat roofs, the sort of things that cluster around airports, and I think of how many of them could be net producers of power to the point where they pay the investment off in 5 years or so and anything after that is pure profit. It's kinda a shame that this isn't being taken advantage of.


Unless the building was designed with solar in mind, it can be challenging. Nobody wants to physically attach the solar structures to the roof, potentially causing a leak, or voiding the roof warranty. Roofing companies want to be the ones to install the attachments. Now it may make more sense to re-roof the building first to get the warranty, and because it will be difficult to get to later. Some systems can be ballasted with cmu concrete cap blocks to avoid penetrations, but then may add too much weight and exceed the structural capacity. California and other areas have seismic concerns. Fire-fighter access pathways, skylight, etc.. The solar capacity of a given roof decreases rapidly, reducing the value of the investment.

Rambino:

Allow me to highlight one key difference between solar energy and oil/gas/coal/nuclear:

When we stop tending to the mines/pipes/boilers/CTs, what happens?  The energy stops flowing, and the lights go out.

When we stop tending to the now-installed solar panels, what happens?  The energy keeps flowing, and the lights stay on.

Every solar panel installed is semi-permanent infrastructure that we get to enjoy for decades at no additional cost or effort.  That other stuff, not so much.


If solar is a "semi-permanent infrastructure", the average nuclear plant is the most permanent damn infrastructure in existence. There's no way in hell solar infrastructure will last 30-ish years, the average age of current nuclear power plants. Existing solar doesn't last that long. Solar inverters, like all electronics and power electronics in particular, are constantly being fatigued, by light/dark cycles (1/day) and power switching cycles (thousands/second). Panels are losing a percent or two a year (the magic of compounding rates...). Coverglass is being covered in dirt and bird shiat. Hail and wind storms are taking out panels. All of these require maintenance, labor and expense.

The idea that solar infrastructure is permanent is a complete falsehood.

Which is kind of strange, since solar represents one of the easiest ways for one to give "the man" the finger and still be able to have nice things.  You would think that conservatives would be all over that.  But they are so terrified that the granola eaters would say "I told you so".
