So you are saying that of the ~1kW of energy that ends up on a m2 from sun only 10-15W is light that is useful for plants? And that is after the power conversio

So you are saying that of the ~1kW of energy that ends up on a m2 from sun only 10-15W is light that is useful for plants? And that is after the power conversion losses? So my solar panel that gets ~200W/m2 could feed 10x the area of plants than the sun directly? Something does not add up here. Edit: 10k/200 is 50 so I don’t see how you ended up with 10-15
