John, No doubt it could be of some benefit in the business of solar energy panels.
However, I think professionals will know about ER as Energy Rating. I don't know if this is the same as the Efficiency Rating for Sunlight on a plane as we talk about it. Is there a professional in solar panels that reads this list?. Perhaps he or she could give a better answer how they calculate the best position for a panel at a given latitude. Best, Fer. PS The stained glass sundial page is nice to look at. Do you see the flies on some dials?
