Best solar panel angle in Heli Mandi
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
26°collects the most energy over a year: 1551 kWh per kWp.
32°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Heli Mandi produces the most over a year at 26°. The design month for an off-grid system is January: at 32° it makes 3.56 kWh per kWp a day, 3% more than at 26°, 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 550 Wp of panels at 70°, versus 340 Wp at 26°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
