Up on the dam, almost everything that looks like a problem becomes an advantage.

The plant sits above the fog line, in thin, clear air that lets far more sunlight through.

The higher you go, the stronger and cleaner the sunlight becomes.

Cold actually helps, because solar panels work more efficiently when they are not baking in heat.

And then there is the snow, which acts like a giant mirror, bouncing extra light up onto the panels from below.

Scientists call it the albedo effect, and it can lift a mountain plant’s output well beyond anything possible in the valley.

A test site at a similar height recorded yearly output far above a typical Swiss plant.

Is that really maintainable?

Dams usually already have maintenance infrastructure like prepared crane positions on top for inspections, so even bigger jobs like replacing panels can be done during regular inspections. And just switching some cables only require personal climbing gear

Speaking of which: I visited the Kaprun dams last year, and the upper one even has its own integrated climbing trail where you can just climb up the wall if you like:

That looks so cool, thanks!

You’ll need some climbing equipment if you need to tighten some screws or connect wires. How often do you think it would be necessary?
