Yes, however the cost of solar, batteries and smart grid infrastructure are declining exponentially, so you have to keep re-doing the comparison every so often.
One could start with just solar, which in India might be valuable on its own to run an air conditioner during the hottest part of the day. Then add a little battery so you can charge your cell phone all night. Then a few years later get a bigger battery and run a refrigerator all night, and so on.
