Solar is viable, you will be looking at a 6-7year payback on the system with interest, 36Lakhs is very high for a 30kW system. The prices should be in the range of 25-27L for an on grid system with a simple structure. Where in Tamil Nadu is this? Ping me if you are looking for more details(mail Id in profile), I work for a company that does solar installations.
