Best solar panel angle in Vasco da Gama
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
19°collects the most energy over a year: 1591 kWh per kWp.
0°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Vasco da Gama produces the most over a year at 19°. The design month for an off-grid system is July: at 0° it makes 3.05 kWh per kWp a day, 7% more than at 19°, 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 860 Wp of panels at 70°, versus 410 Wp at 19°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.

1375thof 3,735 places in India for sunshine, shared: 5.28 peak sun hours a day on flat ground.
+1%solar energy a year compared with the average place in India: 1,591 against 1,575 kWh per kWp.
−14 mindaylight on the longest day, compared with Mumbai: 13 h 03 min against 13 h 17 min.
19°best year-round tilt here; across India it runs from 8° in Tirunelveli to 33° in Leh.
Of the 3,735 places in India, Balotra gets the most sun (5.73 peak sun hours a day) and Jining the least (3.68); Vasco da Gama ranks joint 1375th. In its darkest month, June, 1 kWp of off-grid panels at 70° makes 1.38 kWh a day here, against 1.70 kWh on average in India. The shortest day lasts 11 h 13 min, +14 min compared with Mumbai.
