Best solar panel angle in Chīrāla
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
16°collects the most energy over a year: 1531 kWh per kWp.
5°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Chīrāla produces the most over a year at 16°. The design month for an off-grid system is July: at 5° it makes 3.60 kWh per kWp a day, 5% more than at 16°, and costs 1% 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 780 Wp of panels at 70°, versus 340 Wp at 16°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
