Shade-grown + electricity?
We know that good coffee is shade-grown coffee. Typical shade comes from non-productive trees and bananas. But, what if you could get shade and electricity?
An article from Institute for Science in Society caught my eye. It is about farming and PV solar in Japan but it seems perfect for coffee growing.
Nagashima came up with the idea of combining PV with farming. He devised and originally patented a special structure like a garden pergola, which was tested in fields with different crops and shading rates. The structures are made of pipes and rows of PV panels mounted above ground, and arranged at certain intervals to allow enough sunlight for photosynthesis. There is no concrete footing so the structures can be easily dismantled; the system is designed to allow adequate sunlight for crops and space for agricultural machinery to be used, as stipulated by MAFF guidelines.
