-Solar harvest is greatly affected by the position of the sun in the sky (see above) and how many hours of that sun are available.  A crude generalization is that [[https://mouse.mousetrap.net/blog/2021-12-12-Summer-vs-Winter-solar-harvest-.html|winter harvest will be about half]] of summer harvest.
