You might check out a show called Homestead Rescue. Particularly an episode with a couple who were settled in nicely, but not 100% self-sufficient. I remember the guy had sleep aepnea and needed reliable power for a CPAP machine. There were very detailed mentionings of the required angles, setup and positioning of solar panels... I believe these folks were in Colorado.
