A fixed array in Road Town produces the most over a year at 18°. The design month for an off-grid system is November: at 23° it makes 4.38 kWh per kWp a day, 3% more than at 18°, and costs 0% of the yearly total. Why steep panels win winter.
Off-grid solar in Road Town at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 18° (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 670 Wp of panels at 70°, versus 280 Wp at 18°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
