A hundred manufacturers and technology-makers will field products

Texas A&M Univ.'s Central Texas branch announced this week a pretty clever way to save on its power costs -- turn nearby unused acreage into the world's largest solar test farm, dubbed the "Center For Solar Energy".

(Note: There are many bigger commercial farms, but Texas A&M is billing this as the biggest farm purely for solar prototyping/R&D.)

Announced by Texas A&M System Chancellor John Sharp and A&M-Central Texas President Marc Nigliazzo, the new farm will be far different from commercial farms, fielding hundreds of solar cell designs from dozens of manufacturers.  Mr. Sharp said he hopes to have over 100 manufacturers and solar technology players onboard for the project, which he thinks could draw in $400-500B USD in research over a five- to six-year span.

Why does the university claim that much investment will be inbound?  It's confident that by making itself the nucleus of all things solar, it will become the favored prooving ground for all manner of technologies that produce power from sunlight from traditional photovoltaics to more novel designs like stirling engines.  It says that a product that would take six years to develop elsewhere should be able to be fully tested in only two years, thanks to this concentration of expertise.

The farm will be situated on 800 acres in Bell County, and is expected to produce 50 MW.  That's enough to provide 100 percent of the university's power (with grid storage smoothing periods of low production), plus enough juice for 20,000 nearby homes.  The installation will also provide electricity to the nearby Fort Hood military installation, the largest active-duty armored post in the U.S. Armed Services.  Fort Hood officials were on hand at the project kickoff.

A&M Chancellor Sharp brags, "Obama has charged military installations to use 30 to 40 percent of renewable energy on their bases.  With this [center], Fort Hood thinks it will be the first post to achieve that."

The project will cost $600M USD, but most of the costs will be absorbed by venture capitalists, eager to profit off the technologies tested and developed at the site.  As a result, the university says it does not expect to "expend any capital on the project", and in fact expects to save "$250,000 in its first year of center operation."

Students at the university will also gain new options -- "physics and business degrees with an emphasis in renewable energy; and advanced degrees in those same disciplines" will be offered.

So far the primary private-sector collaborator is California-based PPA Partners, LLC, a renewable energy consulting firm.

But if solar is cheaper to build, people will realize it and put it up themselves or a company will offer to put a system up for you (solarcity, sunrun, tons more).

At the rate of growth for these solar installing companies, they'll have generating assets at the multiple GW level or several large power facilities, but they'll be distributed all over the place.

Solar has a major drawback in that the primary source "turns off" once per day, and is also prone to "fading" when it is "turned on". This means that users will want to have a "fall back" option with their local utility, but that means the utility would have to build their network so it can supply all the solar customers even though they only need electricity on a casual basis, and that cost has to be passed on, meaning prices will go up for everyone else.

Cheaper to build?

800 acres is 1.25 square miles! Now that might not sound like much to you, but let's think about this. To power one school and a handful of homes with solar power the land required alone is a gigantic investment.

And I'm sorry but that's just a disgusting waste of land mass. Yes in America we can get away with it. But there's a lot of countries where it's not remotely feasible to set aside so much land just for solar panels.

Even assuming 25% capacity factor for these panels (which is pretty conservative) means 300 MWh / day, or 109,500 MWh / year for 1.25 square miles of panels.

That means you would need 49,000 square miles to power the entire United States, which consumes 4300 TWh per year. The US covers 3.79 million square miles. That's 1.2% coverage of land mass.

This is obviously a simplification (you would need some kind of energy storage, for example) but shows that land mass is not really an issue.

A handful of homes = 20,000? To be fair, I do think they've overestimated a bit. The average household electricity consumption in Texas is about 1130 kWh/month (or 1550 W). Assuming a capacity factor of 22% (my guess for central Texas), I get 7000 homes total, minus whatever the university would consume.

But regardless, using 800 acres to power 7,000 homes is not a waste of land mass. Do you have any idea how much land it takes to raise livestock or to grow corn for ethanol? If you used that land for corn, for example, assuming 400 gallons per acre as a typical yield, that land could produce about 320,000 gallons of ethanol per year. So those 7000 households have a choice. A year's worth of electricity or 45 gallons of ethanol.

Another way of looking at it is that the total investment is about $750,000 per acre. What fraction of a percent of that is land?

Anyway, it doesn't matter what we think. Solar is already the cheapest source of electricity in a few small markets, and I'd wager that within 20 years (probably sooner), it'll be the cheapest source of electricity in a place like Texas, even if carbon emissions are still free. There is no stopping it.
