Best solar panel angle in Iraquara
Fixed array facing north (azimuth 0°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
12°collects the most energy over a year: 1665 kWh per kWp.
20°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Iraquara produces the most over a year at 12°. The design month for an off-grid system is June: at 20° it makes 4.24 kWh per kWp a day, 6% more than at 12°, and costs 1% 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 910 Wp of panels at 70°, versus 290 Wp at 12°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
