Best solar panel angle in Namsa
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
33°collects the most energy over a year: 1346 kWh per kWp.
39°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Namsa produces the most over a year at 33°. The design month for an off-grid system is December: at 39° it makes 3.07 kWh per kWp a day, 4% more than at 33°, and costs 0% of the yearly total. Why steep panels win winter.

Sizing example. To run a 1 kWh-per-day load through July on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 560 Wp of panels at 70°, versus 400 Wp at 33°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
