Because rooftop hydroponic farms have to be tended to almost daily, or at least for planting/harvesting. Solar panels don't need nearly as much maintenance and allow you to concentrate the actual growing operations for the economies of scale.
Do you mind if I ask why you're so against the idea?

- tux1968 6y agoBut you're ignoring the inefficiency of building separate hydroponic operations on individual rooftops and driving around to all of them, etc. Also as SamBam mention above, you don't have to make a simulated sun. Instead it can work as sun -> electricity -> narrow-spectrum-light-that-plants-convert-at-higher-efficiency. You might even genetically modify plants to be more productive with the smallest spectrum possible.
