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

High in the Swiss Alps, on a concrete dam wall more than 8,000 feet above the sea, someone bolted thousands of solar panels to a place almost no one thought

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.

    I would think solar would be even more efficient high up in mountains.

    Colder temperatures mean they’d stay cooler, produce more power, and for longer… and they are higher up in the air, so amount of photons hitting the panels has to be higher than at sea level, too, further increasing power generation.

    At least thats what I’d assume, applying some common sense and a little educated guessing.
