Power Production
- https://pvwatts.nrel.gov/pvwatts.php - good. 8.5 MWhr/year with 20 degree tilt or 45 degree tilt. 8.2 MWhr/yr with 12 degree tilt. 8.7 MWhr/yr with 32 degree tilt. 7.8 MWhr/yr with 60 degree tilt.
Just Angle
- Useful to study latitude (not much difference) vs time of day (lots of differentce, as this difference is determined by air mass. Think of space: in space around the earth, insolation would be constant.
