On each massive unit, 100 lenses will concentrate sunlight 700 times onto tiny cells just seven square millimeters across.

FORBES: Japan's Green Gold Mine

That is necessary because the balloon concentrates sunlight up to 400 times, and without this cooling the cell would quickly burn out.

ECONOMIST: Monitor

Notably, the camera suffered from an "easily washed-out" LCD when used in sunlight which is potentially crippling at times due to the lack of a glass viewfinder.
