Best solar panel angle in Langford
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
37°collects the most energy over a year: 1256 kWh per kWp.
70°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Langford produces the most over a year at 37°. The design month for an off-grid system is December: at 70° it makes 1.50 kWh per kWp a day, 18% more than at 37°, and costs 14% of the yearly total. Why steep panels win winter.
Off-grid solar in Langford at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 37° (year-round best).
