Go Green, its the best way to mitigate the energy issue. Rates are going to go up and with parity almost on the horizon, its the right time to invest

Accelerated depreciation benefit of 80% is allowed in 1st Year on investments in solar powerprojects

Get upto 90% subsidy in certain states with the MNRE giving 30% subsidy for solar power projects for inhouse consumption. Never has the administrative environment been so conducive towards Solar Energy.

Achieve payback and then have cost free electricity for the rest of the balance life of the system

Move away from polluting sources of energy like your diesel genset. Solar is way cheaper,way better and saves the environment

With diesel and elec price rising at approx 5-8% per year, it makes sense to go Solar. An average diesel genset generated unit costs apprx Rs.22 compared to that of solar at about Rs.8
