Best solar panel angle in Agats
Fixed array facing north (azimuth 0°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
4°collects the most energy over a year: 1361 kWh per kWp.
24°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Agats produces the most over a year at 4°. The design month for an off-grid system is July: at 24° it makes 3.27 kWh per kWp a day, 6% more than at 4°, and costs 5% of the yearly total. Why steep panels win winter.

Sizing example. To run a 1 kWh-per-day load through December on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 970 Wp of panels at 70°, versus 380 Wp at 4°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
