A fixed array in Port-aux-Français produces the most over a year at 37°. The design month for an off-grid system is June: at 70° it makes 1.31 kWh per kWp a day, 17% more than at 37°, and costs 13% of the yearly total. Why steep panels win winter.
Off-grid solar in Port-aux-Français at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 37° (year-round best).
