Best solar panel angle in Qinggang
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
47°collects the most energy over a year: 1615 kWh per kWp.
55°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Qinggang produces the most over a year at 47°. The design month for an off-grid system is December: at 55° it makes 3.70 kWh per kWp a day, 6% more than at 47°, and costs 1% 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 390 Wp of panels at 70°, versus 340 Wp at 47°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
