prc's pv capacity factor is also around 10% last i checked, which is also absurdly low and suggests that they maybe aren't as capitalist as they seem in important respects (i'd be interested in updates)
by 'may' do you mean 'many'
it was easier to justify solar tracking (and concentrating solar, and nuclear) fifteen years ago when solar panels are expensive. but now you have to trade off twenty dollars in mechanical parts for tracking against 180 more peak watts of solar panels. with maintenance costs it's easy for the balance to come out in favor of a simpler system without tracking
Solar tracking makes more sense when you look at wholesale rates over a day. Peak demand prices start right as static solar production falls off so you would need batteries not just more solar panels to sell at those rates. On top of this costs like land, inverters, and wiring gets amaorterised across more hours of production.
Wholesale prices get influenced by the deployed solar power including rooftop solar. Which adds yet another dimension to these models.
Brandenburg has a stupidly large amount of solar compared to a terrible amount of sunlight. https://en.wikipedia.org/wiki/Solar_power_in_Germany#/media/...
Meanwhile the best location in Germany the south southern tip of Baden-Württemberg only has a relatively small fraction of their total installed solar. I haven’t worked out the exact numbers but they are something like 20+% less efficient than they could be. Granted they would need to build more power transmission lines but it’s a small county so such projects would be fairly cheap compared to the efficiency gain.
PS: May solar power plants on the US are over 30% capacity factor and the average is ~25%. We’re a long way from the equator. In a perfect location solar tracking PV should get around 40% capacity factor. You beat 1/pi because over the day an angled panel casts a wider shadow than the width of the panel.
