A fixed array in Khōst produces the most over a year at 31°. The design month for an off-grid system is January: at 47° it makes 4.34 kWh per kWp a day, 9% more than at 31°, and costs 3% 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 410 Wp of panels at 70°, versus 300 Wp at 31°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
