You should get around 1200 kWh to 1450 kWh in a year from 1 kW installation, depending on location in Gujrat and Rajasthan.

For what it's worth, I got 20% of the panel's peak rated power in
sunny southern California averaged over this past spring and summer,

The fellow in http://www.extremetech.com/article2/0,2845,2338834,00.asp
in somewhat less sunny northern california did about the same over
roughly the same time period (I calculated 20.5% from his figures).

If I'm not wrong, the figure above is AC output assuming losses through a battery bank. A grid-tied system should give you about 20% more.

I tend to agree with the figures given by Prof. Chandak.
