It seems natural enough that since greenhouses for growing foods are usually placed in the optimal location for receiving sunlight that solar panels would be a natural to go with them.
One of the problems, of course, is that solar panels have, until now, been opaque, so the sun can’t actually get to the plants themselves. There are a number of transparent solar panels now available, but one of the most intriguing for greenhouses has been developed by Soliculture, a spinoff of the University of California Santa Cruz.
The Lumo greenhouse uses magenta coloured transparent panels, and studies have shown that some plants actually grow better under the magenta panels than under natural sunlight.
