    Really long and thin strips that can’t be angled. They can only be serviced while the track is closed and need to survive whatever debris a train might fling at them. Is this really the best way to place them?

    Solar freaking railways.

      They can only be serviced

      I don’t think this should be a concern, I’ve had them on my roof for 3 years now and not touched them once

      Is this really the best way to place them?

      Seems so:

      But this is just a pilot program. If the system works safely on a busy rail line, it could point to a new way of expanding solar power without covering farmland, forests or mountain slopes with panels. That’s perhaps important in Switzerland, more so than in other places, where renewable energy is urgently needed, but new solar projects can face resistance when they move into cherished landscapes. NIMBY is sadly a global phenomenon.

      For the life of me I don’t understand why people are putting them anywhere before every rooftop is covered with them. Roofs are dead space and unlikely to have debris issues (at least compared to a railway).

          Every parking lot needs approval of the location, its probably a a pain in the ass, and would disrupt parking while being built which impacts sales (or will be perceived to anyway). If this worked, you only need to deal with a small group of people for a very large space.

        It’s companies trying to make a quick buck. They tried this with roads too.

        Obviously every home should have them first and all newly built homes should be built with solar efficiency in mind.

        Deployment on rails is dirty cheap. Can be highly automated and you have highvolt power line just a few meters away.

        If you put solar upon your roof, 2/3 of the costs are labor costs. The material bill encompasses electrics, mounting system, cables, and pv panels that can get reduced on railways as well.

          Cheap if you only count the cost of plopping them down and walking away, the train could kick up enough dust and debris that efficiency is impacted significantly more than installing them on a roof would have been, necessitating installing new ones sooner.

            It’s all theory. That’s why I think it’s worth a try and learn the facts.

            Edit: A rough estimation with averages: 10 kWp gives 11kwh a year in Swiss, 1kwp panel costs 500€, 1kwh energy costs 0,28 EUR in Swiss. Panel material costs for 10 kWp is 5,000€ and earns you 3,080€ (11,000*0,28€) yearly. This shows the value of the idea.

            What if the train runs a street sweeper brush behind it to clean them off every time?

      It seems like the sort of naive gimmick one might expect from a MAD Magazine cartoonist, or Elon Musk on a ketamine binge. It would work to an extent for a while, though whether the amount of electricity generated would justify the maintenance costs to keep it going is another matter.

      The arguments against it are the power yield of a panel pointing upwards, and presumably covered with dirt shed by passing trains. That said, it would suffer less impact damage than photovoltaic roads/bike paths floated elsewhere (the occasional rock impact, as opposed to constant traffic). Also, there is a lot of track, so even if a segment generates little power, it adds up. Not enough to power electric trains, though possibly enough to offset the power bill after operating costs are taken into account.

      I’m guessing this installation is an experiment to quantify these figures rather than a commitment to roll this out more broadly.

        No need to guess, it’s right there in the article.

      The whole point of the exercise is to put solar panels in the not best location. Otherwise this article would be about wireless power transmission from space.
