Solar Panel Installation in Mumbai

Rooftop solar in Mumbai

Mumbai is the most technically demanding rooftop market in Maharashtra: high-rise terraces shadowed by neighbouring towers, salt-laden coastal air, contested terrace rights in housing societies, and four different distribution licensees each running their own net metering process.

Who is buying, and why

Independent houses and row houses in the suburbs, housing societies wanting to cut lift, pump and lobby bills, and small commercial premises paying the city's steep commercial tariff.

What is specific to Mumbai

Shadow decides everything here. A terrace that is clear at 10 AM can be half-covered by 2 PM once the adjacent tower's shadow swings across it, and a string laid out without mapping that loses generation for twenty-five years. The second Mumbai-specific issue is corrosion: powder-coated mild steel starts rusting within a few monsoons this close to the sea, so we specify hot-dip galvanised structures and marine-grade fasteners as standard rather than as an upgrade.

Local demand drivers

Financial and professional services, retail, healthcare, and a dense base of small commercial establishments on LT-II tariff.

Your distribution licensee

Mumbai is served by Adani Electricity, Tata Power, BEST and MSEDCL — four licensees in one city. Your licensee decides your net metering route, portal and approval timeline — check the name printed on your bill. System capacity must stay within your sanctioned load, which is the most common reason an application is rejected.

Generation in Mumbai runs at roughly 118 units per kW per month as an annual average, with the monsoon already factored in. Plan for about 86 sq ft of shadow-free roof per kW. Use the estimator, then read the Maharashtra solar guide for how the net metering process works.
