It’s not just large businesses; even apartment buildings are shifting to solar to reduce their common-area power costs. An apartment in Bengaluru reduced its common-area power expenditure by 30-40% with a 500 kW rooftop solar system. The L&T South City apartment in Bengaluru, with 1,998 flats, utilizes a rooftop system to power the society’s common utilities, lifts, lighting, and water pumps. The apartment installed a rooftop solar system after realizing that, amid rising grid tariffs, it was incurring high electricity costs for powering its common areas. Before the installation of the rooftop system, the apartment was incurring an expenditure of ₹1.5 million (~$15,986.4) per month, an estimated ₹18 million (~$191,837) annually.
