Best solar panel angle in Pursat
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: 1503 kWh per kWp.
8°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Pursat produces the most over a year at 13°. The design month for an off-grid system is September: at 8° it makes 3.74 kWh per kWp a day, and costs 0% of the yearly total. Why steep panels win winter.
Off-grid solar in Pursat at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 13° (year-round best).

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 850 Wp of panels at 70°, versus 320 Wp at 13°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
