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. With 2 axis tracking, it is 12 MWhr/yr.
- Good reality check: Angle optimization in a fixed system gets you only about 6% improvement! 2 axis tracking gets you 50%.
PV Panel Angle Calculator
- 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.
