Best solar panel angle in Marneuli
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
35°collects the most energy over a year: 1370 kWh per kWp.
65°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Marneuli produces the most over a year at 35°. The design month for an off-grid system is December: at 65° it makes 2.85 kWh per kWp a day, 14% more than at 35°, and costs 11% 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 420 Wp of panels at 70°, versus 470 Wp at 35°. The steep array is 12% smaller for the same winter. Size your own system.
