Rooftop solar in Maharashtra: what drives your savings

Maharashtra has some of India's higher residential electricity tariffs, which makes rooftop solar unusually attractive here — every unit you generate yourself replaces an expensive grid unit. Your payback depends on your distribution company's metering rules, your tariff slab and the sunshine your roof gets. Start with our India solar calculator and feed in the Maharashtra numbers below.

Your DISCOM and metering

Most of the state is served by MSEDCL (Mahavitaran), while Mumbai and its suburbs are split between Adani Electricity, Tata Power and BEST. Under MERC rules, residential rooftop systems generally use net metering, so your bi-directional meter nets exported units against imports. Note that as of 2026 Maharashtra has been revising the treatment of surplus export, with a regulated buy-back rate for injected units set around Rs 2.8 per unit and time-of-day tariffs in play, so confirm whether your connection is on net metering or net billing before you size the system. An on-grid setup without batteries usually pays back fastest.

Tariffs and why solar pays

MSEDCL residential slabs rise steeply, and a typical medium-to-high consumption home pays roughly Rs 9 to Rs 11 per unit at the margin once fixed, wheeling and fuel-adjustment charges are included. Because those top slabs are the ones solar erases first, self-consumption is where the money is; model it with our savings calculator.

Sunshine and generation

Maharashtra sees around 5 peak sun hours a day, so a 1 kW array generates roughly 4.2 units daily, or about 1,500 units a year. Interior districts like Vidarbha and Marathwada often do slightly better than coastal Konkan.

PM Surya Ghar subsidy

The national PM Surya Ghar: Muft Bijli Yojana pays Rs 30,000 per kW for the first 2 kW and Rs 18,000 for the 3rd kW, capped at Rs 78,000 for systems of 3 kW and above, for residential connections up to 10 kW. It is disbursed by DBT to your account after commissioning, and collateral-free loans near 7 percent are available. MAHAURJA acts as the state nodal agency; as of 2026 there is no confirmed additional Maharashtra cash top-up over the central subsidy, so check the latest position with your DISCOM.

A quick worked example

A 3 kW system at about 4.2 units per kW makes roughly 12.6 units a day. At around Rs 9 per unit that is close to Rs 3,400 a month in avoided or credited power. After the Rs 78,000 subsidy, many Maharashtra homes recover their cost in about 4 years. Size it with our system size calculator and check monthly outgo on the solar EMI calculator.

Frequently asked questions

MSEDCL covers most of the state, while Mumbai is served by Adani Electricity, Tata Power and BEST. All process residential rooftop applications under MERC rules through the national PM Surya Ghar portal, with net metering the common arrangement for homes.

Residential rooftop systems generally still use net metering under MERC, but the state has been revising how surplus export is credited, with a regulated buy-back near Rs 2.8 per unit and time-of-day tariffs. Confirm whether your connection is net metering or net billing before installing.

You get Rs 30,000 per kW for the first 2 kW plus Rs 18,000 for the 3rd kW, capped at Rs 78,000 for 3 kW and above, for connections up to 10 kW. It is paid by DBT after commissioning. As of 2026 no confirmed extra state cash top-up applies, so verify with MAHAURJA or your DISCOM.

Maharashtra's residential tariffs are among the higher ones in India, often Rs 9 to Rs 11 per unit at upper slabs. Because solar first replaces those costliest units, each generated unit is worth more, giving many homes payback in roughly 4 years after subsidy.
