Dr. Saul Griffith, the author of "Electrify" and the founder and chief scientist of Rewiring America, Rewiring Australia and Otherlab, writes in a column: I recently moved back here to my home country partly because I believe Australians can show the world how much money households can save through simple climate solutions like rooftop solar. How is it that Australia, a country that historically has been a coal-burning climate pariah, is leading the world on solar? The four-bedroom house we recently bought provides a hint: It came with two rooftop solar systems of 11 kilowatts of combined capacity and a battery with 16 kilowatt-hours of storage. This system should produce more than enough to power my family's home, one electric car and both of our electric bikes with some left over to send back to the grid. Solar is now so prevalent in Australia that over a quarter of households here have rooftop panels, compared with roughly 2.5 percent of American households.

Australia pays its solar installers salaries comparable to those in the United States, and it buys most of its solar modules from China at 25 cents per watt, just a little less than what American buyers pay. Our houses are mostly detached single-family, like America, too. But unlike in the United States, it's easy to get permits and install rooftop solar in Australia. Australia's rooftop solar success is a function partly of luck, partly of design. In the early 1990s, regulators considered rooftop solar a hobby, and no one stood in the way of efforts to make the rules favorable to small-scale solar. Looking for a good headline to varnish over Australia's refusal to agree to the same greenhouse emissions reductions as the rest of the world in the 1997 Kyoto climate agreement, the federal government embraced renewable energy policies that set the stage for rooftop solar. Households were given rebates for the upfront costs, and were paid to send excess electricity back to the grid. In 2007, Prime Minister John Howard doubled the rebate, a move that is credited with kick-starting a solar installation boom.

Why has America been significantly slower to adopt this solution to high energy costs? The failures are mostly regulatory: local building codes and zoning laws, state rules that govern the grid connection and liability issues. Permitting can take as little as a day in Australia and is done over the web; in the United States permitting and connecting to the grid can take as long as six months. Many customers just give up. America also generally requires a metal conduit around the wiring; in Australia, the connections can be less expensive soft cables, similar to extension cords. The cost of rooftop solar in the United States depends on many things, including the latitude, tree cover and federal and state incentives. Installation costs can also vary quite a bit, depending on what laborers charge and the local permitting and inspection policies. My friend Andrew Birch, co-founder of the solar and solar software companies OpenSolar in Sydney and Sungevity in the United States, wrote an excellent critique of American rooftop solar and its high price in 2018.

        • Different climates yield different roof shapes and pitches. 1 level homes in hotter regions tend to be flatter and much more easy for do-it-yourself. In northern cold regions here, we find very steep roofs which are much more dangerous to climb by comparison. We also parse out land into smaller lots, which creates a tin of 2 level and 3 level homes. This too increases the risk factors compared to lower flatter rooftops. Taking the DIY factor out drastically increases the costs. Nobody in my area, due to ver

  • Solar panels are useless when the net cannot handle the power.
    Here (Netherlands) the switching gear that passes the power onto the net turns off when the net power becomes to die,
    which happens regularly on sunny days.
    In vast parts of the country it is no longer allowed to set up large solar plants (larger than a single house's roof full) because the net cannot handle it.

    However, our government was stupid enough to privatize the electricity network, so it is not going to be improved anytime soon.
    • You can get inverters that allow powering your home from solar or a battery when the grid is down. The cheap ones don't, it's a feature you have to pay extra for. Most of Europe has very stable electricity supply, so it's not worth it. I can't remember the last time we had a black-out, more than a decade ago certainly.

      If you are suffering from the grid going down then it might be worth paying a bit extra for a suitable inverter and battery. Whole house UPS. As an alternative to a battery, you could buy an electric car that supports vehicle to gird (it doesn't have to go to the grid with the right inverter).

        You technically can, but at least in the Netherlands that is illegal. The fire brigade wants all power in a building to be off if the grid is off or disconnected.

          Huh, that's interesting. I can understand why they want it, but it seems like a bad solution. If it's a house without solar or battery and they want to be sure the power is off then they will have to go to the consumer unit. Sometimes that is located on the outside of the house for easy access by emergency services, or at least the main breaker is.

          As a Dutchman with solar I can confirm the opposition to batteries.
          Recently I asked to have my electric car battery connected via a smart switch to power the house at night but it is a no-go.
          In Denmark it seems to be the other way around, they typically want you to install so-called hybrid solar panels, meaning they come with a battery to smooth out the sunny hours vs. the dark hours.
        • Re:

          So exactly as the summary says, the problem is with regulation and permitting, not technology, not whether. Permitting.

          My system here was a pain to get connected because the local power company dragged their feet for 2 months because they are allowed and they don't want the competition, but its on now and worth every penny.

          Mine also switches off when the power is out, but where I live the grid isn't so bad as to cut out constantly so a battery back up was not a priority for me.

    • Re:

      But TFA is talking about single-house rooftop solar with enough storage to never need to import from the grid... Which makes your comment irrelevant.

      Actually the issue is that Australia happens to have fantastic solar resource and a demand profile that almost exactly matches solar output profile - big peaks during long, sunny summer days due to high air conditioning load. This doesn't work at higher latitudes because the solar output peak remains the same while the demand peak is on cold, short, winter da

        This doesn't work at higher latitudes because the solar output peak remains the same while the demand peak is on cold, short, winter days due to high heating load.

        It depends a bit on your definition of "doesn't work". Residential rooftop solar may not be able to supply 100% of electric demand during winter months in the northern United States (especially with heat pumps). But if it were only, say, 50%, that would still be worth pursuing, no? As an incremental step, I'd be satisfied with running fossil

          Yes, offsetting some of your usage is worth doing. But the UK is already at the point where solar output is destabilising the market because at the solar peak, solar output is about 50% of consumption (in summer) but the peak demand doesn't correspond to the solar peak; the peak demand happens in the morning and evening.

    They don't mention anything about the system cost and ROI time. An 11kW system with 16kWh battery is around $75000 in the US. So, if you are talking about a 10 year ROI, then your electricity bills need to be over $600 a month for this to make sense. I'm guessing this simple math has more to do with the uptake than any other factor. No utility is actually going to give you money for excess production (they may give you a credit for it), since solar ultimately costs them money. The feds and states seem to be over the idea of rebates, since it doesn't funnel more bribes into their pockets like dependence on coal and gas does.

      I can't speak to the cost of battery storage systems.

    • They don't mention anything about the system cost and ROI time.

      That's because that stuff costs more in Australia, which has stricter import regulations than we do, and yet Solar is still more successful there, proving that these considerations are not what are holding back solar installations. QED, you are flapping your mouth and wasting time in a way that does the energy companies' work for them.

      They use to profit from everything, but when it was discovered that they were taking massive advantage of their customers laws were put in place to really make only building new generation capacity profitable. This makes rooftop solar a threat to shareholder profits, and since shareholders of utilities are amoral or immoral they are happy for the power companies to lobby to protect their profits.

      A fair market would decouple the transmission infrastructure costs from the generation costs, and never let the same company own both transmission and generation. In fact the transmission should be handled by actually public utilities, like the bulk of roads. Generation can be a mix of public and private sources.

    • That retrofit system of 11kW panels and 16kWh battery would cost $US15k in Australia. Not 40-70k. Why so expensive?
    • That can't be right on those costs. Australia pays hideous costs to transport anything here as we don't make any of the panels or inverters. Yet we could easily get that system installed here for around $20k USD and our labour costs here are bloody high and every system gets inspected post install and must be installed by a licensed installer so we have more than our share of red tape. I have a 7.4kw system installed with 5kw invertor installed last year for a total cost of $6500 AUD (about $4500 USD), yes that includes some gov subsidies so you could add another $1000USD to the price. Still I find it hard to believe the US has $20k-50k of red tape costs on top of a system install.
      • Those costs aren't right in my experience. Generally 10 kW systems (no battery backup) are $30k here. That assuming you get typical solar installations, not something like solar city roof panels, which are quite expensive. And assuming you don't need roof reinforcement, which is sometimes necessary.

          well that still sounds incredibly expensive, 10kw solar here without battery you are looking at under $10k USD, I guess there must be some politics and big business at play to prevent or minimise solar installs over there as the components certainly don't cost anywhere near that for even the very top end brands?

      • Re:

        Florida is messed up in all kinds of ways but this just seems like a no-brainer for everyone regardless of politics - free energy, 1000s of jobs, investment, energy independence etc. The power companies might have to realign but I don't necessarily see it being bad for them either since they're still the infrastructure and profit from selling energy somebody else put into their grid.
  • That's the smuggest statement I've heard so far this year. He moved his home between two nations for that? His rant is on-line anyway - doesn't Australia have the internet?

    • Yeah, his smugness can go get fucked. Australia ranks amongst the worst in the world in emissions per capita for many of the same reasons the USA does too. Abundance of coal, fetish for huge gas guzzlers, governments that didn't give a shit year on year (which is why both major parties got annihilated in the past election and why for the first time ever the greens have more than 1 seat in the house).

      I only recently saw an article which compared Australian houses based on Europe's energy star ratings. Nearly the entire country would range as E or F and building codes are about 20 years behind countries which actually do have green energy policies in place.

      Your solar panel is worthless when all they do is blast your leaky uninsulated house with the AC turned up to 11. Yeah good that it's solar power, but Australia is massively wasteful when it comes to energy consumption.

      This was probably a tongue-n-cheek comment, but no, we have the "national broadband network" and it's a fucking joke. It was supposed to be a nationwide fibre-to-the-premises fibre rollout, but halfway through this rollout, the government changed and the new guys completely gutted the original plan, and paid Telstra billions of taxpayers' dollars to rehash their woeful copper network. https://en.wikipedia.org/wiki/...

  • "Why has America been significantly slower to adopt this solution ?"

    Probably because Australia is an arid, dry place 15-30 degrees of the equator.
    The U.S. is mostly a temperate forest/grassland, 30-45 degrees off the equator with substantially more rain and clouds, meaning the marginal return is far less.

    But why apply logic, when anecdotes and smarmy virtue signaling is so much more fulfilling?

      The author's point wasn't "Why can't the US be as geographically blessed as Australia?" That'd be stupid - the US can't control its geography. Rather, the author was urging the US to tackle the bureaucratic hurdles and "soft costs" in the US - permitting, system design,

    Australia could learn something from the rest of the world when it comes to saving money: insulate your frigging house. All the solar in the world doesn't do squat if you waste it all on running the AC full blast into your leaky living room.

    Australia lags behind much of the world when it comes to green credentials. Building codes many years behind other western nations, wasteful energy practices such as a preference for huge cars, lack of decent public transport in many major cities, coal coal and more coal providing baseload, all combined make Australia among the highest per capita emitters in the world along with the USA, Canada, and oil rich nations in the middle east.

  • " How is it that Australia, a country that historically has been a coal-burning climate pariah, is leading the world on solar? "

    They finally ditched their 'big banana' PM.

  • Wherever there is a lot of sun, like the California desert and insanely high energy prices at 25c/kWh, like the California desert and insanely high state and federal kickbacks, like the California desert then we definitely see solar rooftops just like the Australian desert. At least people can and are leaving the California desert.

    Iâ(TM)m looking for solar options, once it starts competing with my 4c/kWh pro-nuclear and pro-hydro coop Iâ(TM)ll start installing.

  • I'll let others argue points about Australia versus US. Nation versus nation pissing contests online just leave both parties, as well as the surrounding area, smelling really funky.

    Biden has at least authorized, via the Defense Production Act, for solar panels to not be tariffed. This is a start. Yes, a lot of the panels may be from China, but energy is money, and solar panels are a critical part of a decentralized grid.

    Solar panels do work. I have a few colleagues who have spent the cash to put panels

  • I looked into rooftop solar when I lived in Texas. The economics just don't quite work, even with the huge tax credit (30%!). To a certain extent, it should be obvious that installing solar panels on my roof doesn't make as much sense as installing them at utility scale outside of town. There are three big problems with solar roof for homeowners:

    1.) Rate of return - It wasn't the case then (and probably isn't now) that the money you spend upfront is appropriately paid back. If you spend $20,000 to insta

      europe is actually in better state than most australia

      Wind production is very high in many countries and solar is increasing fast, with countries like Germany and Spain have huge amount of solar power

        We have real winters, they mostly don't.

        • Re:

          I have a solar setup on my roof in New England, it powers my house year round very effectively and it cost about 20K to install before tax incentives. Factoring those in my 12 year loan monthly cost was just about equal to my non summer, non AC running electric bill. We get a ton of snow, we get way less sun in the winter and yet it still works out nicely.

          Solar is viable in these areas despite folks like you continually taking about how its impossible.

          Gee, I wonder how they've beaten rainy Europe on that...

          • Re:

            Dunno about the rest of Europe, but in the UK the 'feed in tariff' (the rate you get paid for returning energy to the grid) used to be quite good - so good that companies sprang up putting solar panels on your house (for "free") so they could get paid the tariff and then pass a bit of it onto you. Then the government reduced it, so now you pretty much just get paid the wholesale rate - which is a lot less than the retail rate you actually have to pay the electric company. Now getting solar is down to just y

          • When I visited in November one year on the USS Abraham Lincoln, I noticed most of their houses were basic 1 level with a simplified low pitch roof. That makes DIY a piece of cake too. Im lucky that my house faces SSW, but 2 stories, a complex roof and higher pitch rules out any DIY. 3 different pitches to the roof.
          • Re:

            Probably the same way that Fox News had an energy expert on who claimed that Germany received more insolation than the US. Turns out only a few places in Alaska receive the same insolation as Germany.

            Here in rainy Pennsylvania, we successfully deploy solar installations, and they work year round. Is Australia "better" for solar?

            Kinda. But all that "better" means is you don't need quite so many panels.
