Counterintuitively, I have previously been told that you can actually grow more than one square meter of plants with one square meter of solar panels. The reason for this is that LED lighting can be designed to produce exactly the frequencies plants actually absorb, and distributed optimally through the day. Current solar technology isn't sufficient to make that cheaper than regular farming for staple crops, but I can certainly imagine it getting there for anything that's grown in a greenhouse today.
- snovv_crash 6y agoRegular solar panels are about 6x more efficient than the photosynthesis of all plants except sugar cane. LEDs reduce some of this headroom by not being 100% efficient, but if the system needs some heat anyways that isn't an issue.
- SamBam 6y agoExactly. One square meter of solar panels can provide enough energy for several meters of plants.
