I would like to see some math on this solar + LED combination.
Solar PV is 16% efficient now. So the LEDs would have to put out light at least 6 times better than sunlight to break even.
Not to mention the LEDs+PV cost money, whereas the sunlight is free.
- TTPrograms 11y ago"theoretically possible" You need higher efficiency solar, which is feasible with non PV techniques.
- maliker 11y agoSome of the latest PV is getting pretty good [1]. How much better is the light from LEDs than sunlight?

- exelius 11y agoCompletely true! I'm speaking about whatever tech we will have in a few decades; we're definitely not there right now. Vertical farming is currently a very niche industry, and will remain that way for some time. But eventually, the technology will catch up, and vertical farming solves a lot of problems we're very likely to have given our current trajectory (loss of farmland due to climate change, water shortages, soil contamination, etc).
