On a commercial scale in the correct regulatory environment you can get good returns from solar production. On the residential side however the best returns come from consumption reduction, then solar generation. Usage cost more than generation (this is how electric companies make money). Ultimately clean renewables are the least expensive form of energy generation, but that includes all costs (environmental, health, economic, etc...). Much of those costs aren't shared by energy producers. What this means is that renewable generation at best will always cost more than the cheapest fossil fuel (in the US this is natural gas), at least until energy storage comes down something like 100 times in price.
That said if you want to get the best returns possible using a tool like the BEopt software (
https://beopt.nrel.gov/ ) can help you ensure you are spending your money in the right places. BEopt is really meant for the US market, so I'm not sure how useful it would be in India (your climate and market conditions are very different). It can also be difficult to use, incorrect inputs mean incorrect results (garbage in = garbage out). My best advice is to hunt down someone in India with a PhD in Heating, refrigeration, and air conditioning or Building Science and see if they have any suggestions.
