A fixed array in Koratla produces the most over a year at 21°. The design month for an off-grid system is July: at 2° it makes 3.42 kWh per kWp a day, 7% more than at 21°, and costs 4% 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 740 Wp of panels at 70°, versus 370 Wp at 21°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
