If it's a poor location for photovoltaics, it's exactly as a poor for photosynthesis
It's very seasonal for both. But we're currently better at storing wheat for 6 months than we are at storing electricity for a similar period.
In most places photosynthesis is limited by (1) the availability of water and (2) the availability of bio-available Nitrogen. Sunlight is less limiting by far.
