Best solar panel angle in Paiçandu
Fixed array facing north (azimuth 0°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
23°collects the most energy over a year: 1591 kWh per kWp.
35°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Paiçandu produces the most over a year at 23°. The design month for an off-grid system is June: at 35° it makes 4.01 kWh per kWp a day, 8% more than at 23°, and costs 2% of the yearly total. Why steep panels win winter.

Sizing example. To run a 1 kWh-per-day load through December on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 590 Wp of panels at 70°, versus 320 Wp at 23°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
