An investment on a 100 KW solar power system gets you financial returns (ROI) in 6 years without any depreciation. If you capitalize on accelerated depreciation, your ROI will be in 5 years. The ROI is calculated on current electricity tariff; consider year over year increase of electricity tariff, your ROI can be faster.On an average a solar system would generate 4 to 4.5 units per KW in India. So, if a company is installing 100KW then it would generate between 1,20,000 to 1,35,000 units per year. We have seen 4.5 units per KW at many of our rooftop projects.

SAVINGS: Calculate (4.5 units * Electricity Tariff per Unit) to get your savings per day.
