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.
It can build up overnight though, so I think the question remains valid.
Smooth and tilted still applies. Also, being a mesa, I wouldn’t be surprised if there was wind as a factor. Turns out the Mars rovers Opportunity and Spirit ended up lasting longer than originally expected in part because the winds on Mars ended up cleaning the accumulated dust on the solar panels.
Good point, great comparison.
yeah i mean even after it’s built up it will slide off in sheets when there is enough sun.
