Next Texas Energy Boom: Solar

Layzej writes: The Wall Street Journal reports: "Solar power has gotten so cheap to produce—and so competitively priced in the electricity market—that it is taking hold even in a state that, unlike California, doesn't offer incentives to utilities to buy or build sun-powered generation." Falling cost is one factor driving investment. "Another reason for the boom: Texas recently wrapped up construction of $6.9 billion worth of new transmission lines, many connecting West Texas to the state's large cities. These massive power lines enabled Texas to become, by far, the largest U.S. wind producer. Solar developers plan to move electricity on the same lines, taking advantage of a lull in wind generation during the heat of the day when solar output is at its highest."

That means you must either lease the right to use the footprint of the windmill, or dual-purpose your farm. Farm equipment can't just roll clear through a wind turbine, so will need to navigate around the turbine; this means more labor, and possibly difficult problems if the turbines are close enough together; not to mention the problem of reaching the turbine with heavy equipment for maintenance, driving through the soy and corn.

I think only First Solar is the only big boy that's based in the US.

    I disagree mostly because solar really didn't get cheap until the Chinese began to flood the market with panels, around 2010-2011 or so. Before China, solar panels cost around $2.50/Wp; after China started the flood, they could be had for as cheap as $0.75/Wp.

    All that said, you get what you pay for... Solarworld for instance has the 25-year power output warranty, 17-18% conversion, and high wattage densities (255+ watts per panel), whereas the real low-end Chinese stuff is barely warrantied for a year, might get 10-12% conversion, and might get you 160-200-watt panels (in real-life testing; forget the label's claims).

    At current rates of decline, the price will be under 10 cents per watt by 2020.

    Solar cells are going to collapse fuel demand world wide. While the need for fuelbased generators will remain until we get better batteries (also improving about 5% per year pretty consistently for a long time) if we could cut fuel usage by 30%, it would probably collapse the price of diesel.

Quite honestly, the R&D incentive money is best spent on the challenge that follows, not the first-mover challenge: energy storage. By subsidizing the PV panels up front, you get the industry moving which will create its own R&D investment. By increasing non-dispatchable generation on the grid, you need to have improved energy storage and demand control solutions.

    From the small view I have on where money was being spent, 6-12 years ago a tremendous amount of investment was being placed into these areas for technologies that are viable now.

Many people always held the opinion that corn ethanol in particular was stupid, but it was still just an opinion when not supported by real world data. Also note that if oil prices had stayed as high as they were during the Bush presidency, ethanol would (still) be competitive with gasoline - and this is likely to happen again at some point, so having distribution infrastructure and cars to utilize it is a good buffer against price shocks.

    > I disagree mostly because solar really didn't get cheap until the Chinese began to flood the market with panels, around 2010-2011 or so.

    It wasn't the Chinese so much as solar grade silicon production. Prior to about 2009, demand for silicon for solar cells was smaller than for electronics. So solar piggy-backed on existing silicon foundries. But electronics-grade silicon is expensive (~$400/kg) because even one defect can ruin a chip. Eventually solar cell production got big enough that solar-grade silicon was worth it's own foundry lines. Defects in a solar cell just degrade the output a little bit, they still function just fine. The lower quality product was much cheaper to make ($18/kg last time I looked). Since the raw silicon was a major component of final panel cost, you had dramatic cost reductions for a few years.

    Now we are back to more incremental cost reductions, but the panels are now so cheap that the "balance of system" (panel mounts, labor, wiring, inverters or transformers, permits, etc.) is the majority of the cost, and that's where work is being done to reduce them more.

    Solar cells are a major piece of the puzzle, and arguably the biggest piece.

    There are other things falling into place as well.

    Relatively inexpensive MPPT controllers. Yes, these require an inductor coil to get the voltage from the panels (100+ volts) to a usable voltage/amperage combination for the battery bank. To boot, most MPPT CCs are multi-stage, so batteries are not boiled when near 100% SoC.

    PWM controllers are cheaper, and because solar panel technology is so relatively cheap, it might be cheaper to throw more panels on as opposed to using a smarter charge controller. In fact, I bought a decent 60 amp, 12 volt, multistage CC with a voltmeter and ammeter for $8.

    Inverters are not standing still. One can have a choice between charging solar batteries for off-grid use, using inverters to feed the grid, or anywhere in between.

    The component that sucks the most is still batteries. They don't hold much energy relatively, and need to be replaced every 5-10 years. Even here, there is progress. For "drop in" batteries, there is a "Smart Battery" brand that goes where flooded lead-acid batteries are used. A battery charger that works with LiFePO4 is required, but since the special discharging circuitry is on the battery, this not just provides a longer usable life, but lead-acid batteries get damaged if drawn below 50% SoC, while lithium batteries can be drawn down a lot further (3-10%) before suffering ill effects.

    What is happening with solar is a combination of the above factors, which gives energy independence, which builds momentum behind it. It used to be that solar power was for hippies, but both the far right and far left have embraced the concept, and it is more of a mainstream, "why not?" as opposed to "why" concept, especially with RVs, camping, and boating.

During the day this base load supplies about 50% and almost 100% at night. The ramp up for daytime demand was handles by faster ramping systems such as gas and hydro. The problem comes when solar makes up for more than 50% of daytime usage. Without storage one would start ramping down the conventional production to make room for the solar production. It would then need to ramp back up again for night.
