Ins$tute s Investment (in lac Rs.) Net Energy Savings p.a. (energy units in lacs) Net Monetary Savings p.a. (in lac Rs.) Payback Period months Financial Analysis years, 6 months 6 years, 10 months 18 years, 4 months Payback Period on total investment: 2 years, 5 months

19 Addi3onal Benefits In Summer SPV systems running at full efficiency can compensate for the A/C load in departments SWHS systems in departments can provide hot water in pantry for dishwashing, Tea etc and shall reduce electricity. All year round swimming pool usage with minimum investment SWHS rebate of Rs. 75 per 100 liters can be availed from electricity bills of the ins3tute, which acts as addi3onal incen3ve for installa3on in residences and may be passed to residents Steam from Steam Cooking system can be u3lized for hot water produc3on Systems have a long life 3me of 20 years Future Scope Solar Air Condi*oning: This can be done through passive solar, solar thermal energy conversion and photovoltaic conversion (sunlight to electricity) Solar Street ligh*ng with Light Emipng Diode (LED) for opera3ng at specified hours of opera3on per day
