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.

    …the assumption was simple, that solar belongs low and warm, on sunny roofs and flat fields, not up in the freezing thin air of the mountains.

    Well that’s a stupid assumption. what other kind of electronic works better when it’s super hot??

    The country makes plenty of power in summer, but runs short in winter, when demand climbs and it has to import electricity.

    That gap is set to grow as the nation closes its nuclear plants.

    Damn, two stupid ideas from the Swiss. At least the fabled “someone” put those solar panels up there. 🙄
