negative solar radiation
https://www.pveducation.org/pvcdrom/p...
According to this model and TMY3, solar radiation on a building wall facing south is sometimes negative. Is it reasonable?
yes i saw it when running on fairbanks data
Attach your IDF file? Did you use the TMY3 from energyplus.net or from climate.onebuilding.org?

I used the formula from this, not energyplus: https://www.pveducation.org/pvcdrom/p... I used TMY3 data.
Then I don't think I can help you. Not sure who wrote this formula, etc, etc.

what would be the standard way of calculating the solar radiation received by a wall?
My result is for Fairbanks. Is it too special a place chosen? Or is it reasonable to have negative solar illumination?
