After Blackouts, Texas Became a Top State for New Solar Installations as Thousands Install Microgrids (houstonchronicle.com) 60

"Thousands of Texans who have turned to solar power and battery storage, creating so-called microgrids, as a solution to blackouts," reports the Houston Chronicle.

"With a venture creating the same little power plants for apartment buildings, Texas has become a national leader in residential solar power installations." From 2019 to 2020, small-scale solar capacity in Texas grew by 63 percent, to 1,093 megawatts from 670 megawatts, according to the Energy Information Administration. In the first three quarters of 2021, another 250 megawatts of residential solar were installed in the state, according to the Solar Energy Industries Association. In last year's third quarter alone, Texas ranked second behind California in the amount of power from new installations during the period, the industry's Washington, D.C. trade group said.

Surging demand for residential solar power in Texas after the February 2021 freeze put pressure on installers to keep up, said Abigail Hopper, president and CEO of the association. The race to buy new rooftop panels has slowed some, she said, but Texas remains among the top three states for new installations. And the shrinking price of solar cells will help support its growing popularity, Hopper said.

"I think as more and more Americans really struggle with the impact of severe weather — everything from fires, the cold, hurricanes, droughts — and see the impacts on power and power outages, you're going to continue to see folks looking for resiliency," Hopper said.

    As more people adopt solar for their homes, the power companies won't sit idly by and lose millions of dollars each year. Instead, they'll adopt monthly fees [clickorlando.com] to solar users and/or reduce or eliminate net-metering to solar customers. In short, they'll kill the industry [cnn.com] and the jobs which go with it.

      Nope, the way the power companies are going to approach this is to bribe gov't officials into enforcing laws that REQUIRE people to connect to the power grid whether they want it or not. That, and lots of building code beauracracy (permits, fees, and fines) to badger the people attempting to go off-grid.

        This is a safety issue, actually. When there's a blackout in your area, the utility has to send someone around to fix it, and there are plenty of cases where idiots backfeed their generator - they plug their house into the generator using a suicide cable and forget to cut the main breaker, backfeeding the generator. That power then goes up to the transformer and gets transformed into the distribution voltage (around 7200V). If you're trying to clear a branch off some trees, the last thing you want is for a dead line to be electrified by someone backfeeding.

        Sure, there are a lot of precautions, including grounding, equitpotential and line tying (basically, all phases are tried together and grounded on both sides of the work area. This makes it safe, but it also means clearing a branch now takes 45 minutes instead of 5. But it's better than killing someone.

        And demonstrations have shown that even when all this happens, no breaker will trip - none of the house breakers will trip, the generator breaker wouldn't trip, and none of the distribution fuses or other things will trip either.

        So if you have a generator, they do make proper generator hookups with physical lockouts that let you turn the main breaker or generator breakers off, but won't let you turn both on - one must always be off to turn the other on.

        With solar, the same thing applies, but you have the added complication that you need to feed power to the grid. So you have the odd case where you have to feed power to the grid, and also make sure you're not backfeeding the power in case the power goes out.

        This is why inverters are so sophisticated - because they are line-sensing inverters. They sense the phase of the AC and make sure when they feed power, the phase is in line. Some can also even detect reactive power and apply power properly (this can make the power grid more robust but reducing reactive power and bringing everything back in phase). But they also detect if there is line frequency - if the line frequency disappears, they have to shut down to avoid backfeeding problems.

        If you opt for a single inverter system over a microinverter system, or you go for a full power management center, you can have the ability to have an "emergency bus" - a power sub-panel where power can be provided either by solar or mains - the inverter will feed the sub-panel directly, using solar when it can, augmenting with grid when it can't. If there is too much power, the excess is pumped to the grid like usual. If there is a blackout and the solar is providing enough power, the sub-panel will be powered completely by solar so that panel can be for essential loads like fridges and other things that should remain powered. Home battery storage systems like Tesla Powerwall also do the same thing - they will take power from mains and feed a essential bus sub-panel, providing power from the grid or batteries as needed,

        Of course, the most sophisticated system will be a power management center where grid power, solar power, and battery power is all brought to one location and it's managed from there - you can designate circuits as always on, grid/solar only and other things, and the system can optimize for economy - using solar for as much as possible, charging the battery, and so on. The fancy ones even have provisions for electric car support - letting the car charge at a rate that consumes excess solar energy so you're basically getting it all for free.

        Problem is, these are issues that do require a proper solar contractor to properly install because you don't want your system to accidentally create a backfeed situation.

      There's a problem being seen in California here. The subsidies for solar are essentially being paid for by the bills from non-solar customers. And solar is being bought almost exclusively by people with above average income. Which means overall, rich people are paying less than poor people. If you cut back on subsidies though, then it takes a much longer time for solar to pay for itself (and many customers want this, they're not getting solar to be good citizens).

      Utilities should figure out how to separate costs; cost for production is one part of the bill, and cost for creating and maintaining power lines is a second part of the bill. But it won't happen, the utilities won't voluntarily let power reduction or safety measures reduce their profits. Which is why the public utility commissions give them a fixed income, which means that the more energy they save the higher the profits they get. The PUC needs to step up and support solar here. The for-profit model needs fixing.

        I hate to support the utilities, but I’ll give them a little leway here: I have an 8kW PV system that offsets 120% of my annual energy consumption. I am lucky to be on a legacy net metering plan. My average power consumption is ~1kW, which is essentially what a utility designs their infrastructure for. My neighborhood has ~25 homes served from a single 25kVA transformer. That means when I am solar power, I am using ~25% of the transformer’s capacity. About half of the other homes also have solar, and nobody has batteries. So, during the day, the transformer is loaded at about 200% of its nameplate, which will cut its life down to maybe 10 years.

        For the utility to remedy this on their end they need to install ~3 more transformers and split up the 120/240V network a bit. Without any additional revenue.

        For me to remedy this I need to add about 20kWh of battery, which would allow me to self-consume my solar plus export at a maximum of ~1kW, which essentially makes me look like a normal (small) customer to the utility. But my utility bill won’t change either.

        I’ll do it for reduced grid dependence, but that lack of an economic justification is a hard pill for most people to stomach.

          Uhmm, not sure I follow how you think the transformer is loaded 200% of it nameplate.

          You may be only using 1kW average, but you've got solar panels shading your house. The other half of your neighborhood without solar are likely using much more than 1kW each to keep their houses cool. And since you're all on this side of the same transformer, a lot of the excess electricity you're producing is going straight to the non-solar houses, without even going through the transformer at all.

          The only time the power company might have to put in more transformers due to solar would be if everybody behind the transformer are net producing more than the neighboorhood is consuming. And doing so at a level approaching more than the 25kVA the transformer is rated for.

          Where I live, the power company buys any excess kWh's from me at wholesale price levels (super cheap), then turns right around and bills the non-solar houses using my excess kWh's at retail pricing. The power company is thus turning a profit from my excess kWh's. You shouldn't worry about the power company having to install more transformers -- they'll do it and profit off your cheap electricity if you're really producing that much excess to necessitate more transformers.

          • Daytime generation is about 60kW by my estimate, and consumption is likely under 12kW at that time of day-- low air conditioning use.

      Well, guess what, maintaining connection to your home still costs even if you're not using it at the moment. Maintaining standing power reserve for when you run your battery dry still costs. Upgrading all the transformers and other systems to be capable of running two-way, and dealing with wild swings of everything the moment sun goes behind a cloud costs a ton. Running peaker power plants for when renewables fail to provide enough electricity costs ten tons. Who exactly do you think should pay for all of t
