Best solar panel angle in Zwedru
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
7°collects the most energy over a year: 1345 kWh per kWp.
0°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Zwedru produces the most over a year at 7°. The design month for an off-grid system is July: at 0° it makes 3.20 kWh per kWp a day, 3% more than at 7°, and costs 1% of the yearly total. Why steep panels win winter.
Off-grid solar in Zwedru at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 7° (year-round best).

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 1,030 Wp of panels at 70°, versus 380 Wp at 7°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
