Interesting, do you have any links about this startup ?

You say it's more expensive, do you have a rough estimate of the cost of such a panel (with or without motors) ?

I'm asking because I'm currently working on a small scale automated solar concentrator and I haven't managed to get an idea of how much such a panel costs.

I have only found some sun trackers for photovoltaic panels but they have different angular accuracy requirements than CSP.
