Made a video, should help folks figure solar needs. Winter vs. Summer Solar, Camping/Overlanding. Calculations & Tests, North/South Borders.
Video works, won't play embedded here, click "watch on Youtube " to see video. Additional info in video description. How much solar power when Camping or Overlanding, in Winter vs Summer? Here I use 460W of solar panels, a good amount for popup truck camper or van size roof. I show the calculations using the government PVWATTS.COM site, for max solar power in both Phoenix and Boise, and Dec/Jan vs. Jun/Jul. Then I test the panels actual output at Noon on a perfect AZ November day, both flat as you'd have roof mounted, and also at perfect perpendicular sun angle. This is to show best case power production vs. actual roof mount.
