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.

    That’s what is happening but it not happening fast enough. Batteries are great but unless you build out a LOT of them and combine with intelligent grids and power consumption you aren’t covering the output of a nuclear power plant. If you are decommissioning a nuclear plant then you had better have alternative power available otherwise you end up like Germany who did that and then had pull a lot of power from Frances nuclear excess as well as burning extra gas for power. I like renewables, I have solar + battery at home, I’ve built flow battery models and fuel cells to experiment with. I’ve written software to turn my house (and hopefully include my neighbours soon) into a virtual power plant based on my houses output as well as the wholesale market price. It’s difficult to manage when people expect a light to turn on at any time they want. I just get tired of people saying renewables are the only option and when it inevitably isn’t just yet having to burn more fossil fuels when the existing nuclear plant can continue
