A fixed array in Siliguri produces the most over a year at 28°. The design month for an off-grid system is July: at 13° it makes 3.21 kWh per kWp a day, 7% more than at 28°, and costs 3% 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 650 Wp of panels at 70°, versus 390 Wp at 28°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
