US Solar Production Soars By 25 Percent In Just One Year (arstechnica.com) 194

Yesterday, the Energy Information Agency (EIA) released electricity generation numbers for the first five months of 2024, revealing that solar power generation increased by 25% compared to the same period last year. Ars Technica's John Timmer reports: The EIA breaks down solar production according to the size of the plant. Large grid-scale facilities have their production tracked, giving the EIA hard numbers. For smaller installations, like rooftop solar on residential and commercial buildings, the agency has to estimate the amount produced, since the hardware often resides behind the metering equipment, so only shows up via lower-than-expected consumption.

In terms of utility-scale production, the first five months of 2024 saw it rise by 29 percent compared to the same period in the year prior. Small-scale solar was "only" up by 18 percent, with the combined number rising by 25.3 percent. Most other generating sources were largely flat, year over year. This includes coal, nuclear, and hydroelectric, all of which changed by 2 percent or less. Wind was up by 4 percent, while natural gas rose by 5 percent. Because natural gas is the largest single source of energy on the grid, however, its 5 percent rise represents a lot of electrons -- slightly more than the total increase in wind and solar.

Overall, energy use was up by about 4 percent compared to the same period in 2023. This could simply be a matter of changing weather conditions that required more heating or cooling. But there have been several trends that should increase electricity usage: the rise of bitcoin mining, growth of data centers, and the electrification of appliances and transport. So far, that hasn't shown up in the actual electricity usage in the US, which has stayed largely flat for decades. It could be possible that 2024 is the year where usage starts going up again.
Since the findings are based on data from before some of the most productive months of the year for solar power, solar production for the year as a whole could increase by much more than 25%. Overall, the EIA predicts solar production could rise by as much as 42% in 2024.

    As the subject says, The Economist had an excellent review of Solar a few issues back:

    https://www.economist.com/week... [economist.com]

    Most of it is paywalled, however, the gist is that Solar has been growing exponentially worldwide the last 10 years or so. Newly installed capacity is growing by about 50% year over year IIRC. We cannot expect this rapid growth to continue as fast as now for many years - but that has been said every year.

    Ever year new projections have been released about where we'll be in 10 years. Every year it's taken less than a year to beat the 10 year projections (IIRC).

    Greenpeace estimates of where we would be in 2030 in the "best case scenario", released in 2016 (I think?) was beaten last year.

    In short: The growth of solar is absolutely exceeding all expectations by orders of magnitude. The challenge will be grid scale battery storage. Solar is on path to produce abundant electricity "in total", but there's an urgent need for battery storage for evening/nighttime/morning use.

      People are realizing that they can make their own electricity and be free of utility prices. In places with unstable grids they can have power when the grid is down.

      Not just in the home, for their car too. No more worrying about gas prices, just charge up at home with solar energy.

      The main issue is that some people are left out of this due to renting or not being able to afford the investment. It's a great investment to make though, typical payback in the UK is 2-3x better than the best available savings ac

      • not being able to afford the investment.

        It's easy to get a loan to install solar.

        What you save on electricity is often more than enough to cover the loan payments.

        Once the loan is paid, the panels increase the resale value of your home but are often exempt from tax appraisals.

        • They should be exempt. You don't get taxed on the value of your refrigerator, washing machine, dryer, water heater, or any other appliance. It's complete bullshit in states where this isn't outlawed as these systems depreciate over time and are susceptible to damage.

        • Solar isn't quite as risk-free as you would hope, though. The panels are usually bought from one company and then you have an operating contract with another company and the loan is with a third-party financial institution. If you have any trouble with either the installation company or the operating company and your panels aren't generating, you're still on the hook for the loan. In the US, there is a deluge of fly-by-night solar companies, and many people have been burned. Those who can't afford to pa
          • And adding solar panels is unique among home improvement activities in that there are fraudulent and shady contractors, but we don't see that in literally every other aspect of home improvement?

            Sorry, if you're a homeowner you have to deal with that shit on literally every improvement you do. That's why you do your legwork to make sure you're hiring competent people that know what they are doing, and are interested in being there long term.

            • Solar panels are unique because, unlike other home improvements, there isn't the same type of ongoing operating and maintenance agreement.
        • 100% this.

          We installed rooftop solar two years ago. Paid cash. Got a fat tax credit. And the state I live in passed a law that says adding solar panels cannot increase the tax assessment of the home.

          We offset 70% of our electric usage, including charging EVs. During summer months, we're carrying a credit with our electrical service provider. I calculated our break-even at about 6 years and we're on schedule for that.

          I would have put even more panels on the roof if local building code would have allowed

        Have you got a link to the maths on that for the UK? I’ve run the numbers for myself several times, and it’s always felt like the ROI wasn’t as good as it needs to be for it to work for me financially. The capex and labour costs were just too high to be offset by the savings, so far as I could tell.

        • by AmiMoJo ( 196126 )

          Sure. Use this EU tool to estimate how much solar energy you could produce: https://re.jrc.ec.europa.eu/pv... [europa.eu]

          You need to tell it approximately where you live in the UK, and the angle your roof faces (the azimuth). You can use the standard 35 degree pitch if you don't know what your roof's actual pitch is, it's usually about right for the UK.

          From there go to your energy provider and find out how much electricity you use per year. Plug that and the amount you can generate into this website: https://great-home [great-home.co.uk]

          • by shilly ( 142940 )

            Thanks! Will have a play and see if the calculations look more promising. I’d thought FITs were a thing of the past — that would make a big difference. We have induction hob and an EV, but haven’t yet got a heat pump. That’s the big obvious other change, but it does require a significant additional upfront investment. Part of me is tempted to hold fire for a year and see whether Labour introduces some new / better / more sane incentives

            • by AmiMoJo ( 196126 )

              Yeah, I think a lot of people are waiting to see what Labour does on this.

              The FIT now is crap, but several energy providers offer much better rates. I think OVO can go as high as 40p/kWh under some circumstances. Octopus have an "agile" feed in tariff if you want to try it, which can get up into the 30p range, but I think at the moment the fixed 15p rate is a better deal for most people

              You can get even better rates with Octopus if you let them control your battery. Basically they can tell it when to dischar

      Solar is on path to produce abundant electricity "in total", but there's an urgent need for battery storage for evening/nighttime/morning use.

      Some remarks:
      1. Battery storage is just one option.
      2. A modern grid will adjust energy consumption to supply, reducing the need for storage. Get one.

    • The challenge will be grid scale battery storage. Solar is on path to produce abundant electricity "in total", but there's an urgent need for battery storage for evening/nighttime/morning use.

      And we're getting it. There are already storage systems that fit on the end of arrays. https://www.dovetailsolar.com/... [dovetailsolar.com] It can be placed on already installed arrays.

      This stuff is happening, and the naysayers are several steps behind.

    • In short: The growth of solar is absolutely exceeding all expectations by orders of magnitude.

      It's important to point out why this is happening. It's not because of subsidies, or government mandates or climate change fears... it's because it's cheap. This is how we'll move away from fossil fuels, by creating new technologies that are actually better and cheaper, that people want to adopt.

      The challenge will be grid scale battery storage.

      Will it? I'm not so sure it will be such a challenge. Batteries also continue getting cheaper, and better, at an exponential rate. And battery storage is not the only option. As solar gets cheaper and cheaper we'

      They do prey on the inertia effect many people have.

      All the while, we're quietly and rapidly working the technology. That's the whacky thing about this. It requires no breakthroughs like fusion, no huge startup costs like nuclear, all applied technology that is quite scalable, and easily upgradeable.

  • Our area got offered community solar last year. Instead of installing a custom solar setup on your roof, buy a share of a solar farm in out where retired farmland is near transmission lines. The solar power produced gives you credit on your electric bill, at a 10% discount in your benefit. Their projects get fully subscribed as fast as they can build them.
