A fixed array in Cukai produces the most over a year at 2°. The design month for an off-grid system is December: at 22° it makes 3.24 kWh per kWp a day, 7% more than at 2°, and costs 5% 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 1,020 Wp of panels at 70°, versus 390 Wp at 2°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
