Best solar panel angle in Rāichūr
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
18°collects the most energy over a year: 1664 kWh per kWp.
0°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Rāichūr produces the most over a year at 18°. The design month for an off-grid system is July: at 0° it makes 3.80 kWh per kWp a day, 7% more than at 18°, and costs 4% of the yearly total. Why steep panels win winter.

Sizing example. To run a 1 kWh-per-day load through June on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 730 Wp of panels at 70°, versus 330 Wp at 18°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
