Since the original article I shared looks like it was published on an AI-powered content farm, here's a 2023 Reuters article on this solar plant: https://www.reuters.com/business/sustainable-business/switzerlands-solar-dam-sun-snow-perfect-mix-green-energy-drive-2023-02-06/
Or you can go to the source and check out the AlpinSolar website: https://www.axpo.com/ch/en/energy/generation-and-distribution/solar-power/alpinsolar.html
@roadskater @samerion Happily, it has also been instantly flagged on Wikipedia as an unreliable source 
@samerion Agreed. The site that published this article looks like a content farm, and it's likely they use AI to write part or all of their articles. They're mimicking the style of content that was popular in the BuzzFeed days. The photo is either Photoshopped or AI generated. The Muttsee dam doesn't have a building halfway along the dam wall, plus the height and curvature of the wall shown here doesn't match. According to the Axpo website, the actual content of the article is accurate though.
@crazyeddie I think people have a knee-jerk reaction to things that haven't been done before. They'll keep telling you the return on investment isn't there until you actually do it and prove that these difficult-to-install solar panels work MUCH better in winter than the ones installed in the lowlands. Also, according to the Axpo group website, this is very much a proof-of-concept project in which they're testing to see what does or doesn't work. I'm very glad this is working for them!
This is really cool.
Switzerland bolted 5,000 solar panels onto a dam wall 8,000 feet up in the freezing Alps where everyone said solar made no sense, and the plant now makes three times more winter power than any farm down in the valleys https://www.ecoportal.net/en/switzerland-5000-alpine-solar-muttsee-dam-winter-power/28487/
