You guys are overlooking the important part of this, overpowering solar energy focused on a water cooled PV cell works.
Maybe not as well as it could given a simpler design, but still this proves you can overpower a solar cell.
Now how about a rotary mirror system that allows the solar cells to produce synchronous AC current for the grid. This could provide greater efficiency from the cells as it would temper the heating effect.
The whole floating thing is kind of strange, and the use of a lense means it can only work in direct sunlight, not diffuse cloud light.
Plus the heat from the cooling water is not collected.
Combined with algae growth systems that use the excess photosynthetic light, and provide rapid evaporation to distill water and collect heat, and biofuel systems to process the algae using solar power, this system could produce maximum hours of peak electric power from the expensive part of solar power,the PV cells, while providing waste water recycling, biofuel (hydrogen,biodiesel, ethanol, and methane), organic fertilizer, and heat for either heating or cooling (adsorption cycle)buildings.
Solar cogeneration, the next wave in renewable energy, hang 10!
