Where are getting UV prediction from? I don’t see that in my forecast at all.
As for solar radiation and heating and cooling your house is complicated.

I have been working on that myself but only for the current day so I can determine if it is cloudy.
I’m curious about your thought process for your heating and cooling based on solar radiation (SR). Are you assuming a certain external heating rate of your house based on a given SR?
I am up to 5 different SR estimates that are more accurate at different solar angles. I, unfortunately, do not have solid data as I have had clouds for weeks and I need a few days of pure sun to test my assumptions.
