Concentrated Solar Power
Discussions center on using mirrors to concentrate sunlight for thermal energy generation, including solar power towers, molten salt storage, and Stirling engines, often comparing efficiency to photovoltaic panels.

No it doesn't: https://en.wikipedia.org/wiki/Concentrated_solar_power
I'm not sure if you are joking or not, but something like this is still used for solar power generation.https://en.wikipedia.org/wiki/Solar_power_tower
Cant you use sunlight and guide it through mirrors with rotating shelf's?
Intriguing, but wouldn't it be even more efficient to just paint something black and let the sun heat it directly?
That's easy, just put solar panels in the receiver!
wouldn't the energy efficiency be low? effectively: light source -> PV panels, focus etc are bound to be difficult (long distance so parallel rays, any tiny deviation... well schlieren photography) and then there's diffuse scattering
My physics are a bit crap lately but aren't there some cheaper and low tech solutions to the problem. If you got the mirrors and the heat won't some kind of sterling engine with the cooling element dug in the earth have substantially lower costs?
Solar thermal panels can be used for this!
If there is sun why not skip the middle man and use an array of mirrors for direct heating?
True, solar thermal using steerable mirrors, can do it.
