This needs the additional information that photosynthesis is incredibly inefficient. It's <5% IIRC, so we already have solar panels almost a magnitude better than what nature did.
(RuBisCO as the protein at the center of the process is also quite strange: it's huge and slow. As in 'this ain't funny any more, start working' slow with about a reaction per second.)
