It nearly cools itself, since the mini multi junction are part of the panel and not a tiny spot alone in other farend part like the zenith solar system. So the mini multijunction uses the 200 times larger panel area like a cooler.
And it's 200 suns concentration and not 1000 suns like Zenith Solar's system.

Zenith system uses water to cool, and so produces hot water for shower. They uses the heated water as part of the efficience calculation, leading to the "fake" claim of 72% efficience. The solar cell efficience it's a bit more than 40%, quite good, since it uses 1000 suns concentration and not just 200 suns.
But 1000 suns would require cooling help.
Welll, solar energy and hot shower source (help save electricity) it could be.
I asked your exact question to a company who created a similar concentrator to insolight panel, Morgan Solar, but that required tracking.
If Insolight could find way to create optical precise to 1000 suns concentration, and for viable prices for such opticals, they could have a chance. Maybe China production costs would be the key.

The thing is though, it all comes down to how much of the sun's energy you can gather - and that comes from the area the sunlight shines on.
