Peak sun hours a day on flat ground. Each dot is one place (the 900 largest).

The sunniest place in India is Balotra (Rajasthan) with 5.73 peak sun hours a day on flat ground; the least sunny is Jining with 3.68. A 1 kWp array at its best angle makes from 1,222 kWh a year in Jining to 1,825 kWh in Leh — 1,575 kWh on average.

The best year-round tilt runs from 8° in Tirunelveli to 33° in Leh. Off-grid systems are sized for the darkest month and do better steeper, at 12° on average: at 70° that month brings 1.23 kWh per kWp a day in Kollam and 3.17 kWh in Leh.
