If you are using a Davis pyranometer, you can keep global_coeff to 1. My Davis weather station is at latitude 46.34 N and I use this value. If you have another solar or light sensor, you will have to adjust the value of global_coeff, and possibly the B_coeff, until you have good results - i.e when the formula will reporting sunshine when shadows are visible, and no sunshine when there is no shadows.
