For urban Nepal , we are looking at off grid applications. We are looking at only back up power. You need to decide which things you still need when there is no city electricity. For things like running the water pump, these can be done when city electricity is there and you need not plan these for the solar. You need to decide what kind of investment you want to make in solar.
