Best solar panel angle in Mamou
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
13°collects the most energy over a year: 1597 kWh per kWp.
0°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Mamou produces the most over a year at 13°. The design month for an off-grid system is July: at 0° it makes 3.70 kWh per kWp a day, 6% more than at 13°, and costs 2% of the yearly total. Why steep panels win winter.

Sizing example. To run a 1 kWh-per-day load through June on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 860 Wp of panels at 70°, versus 340 Wp at 13°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
