Rooftop Solar in Maharashtra
Maharashtra has 5 different DISCOMs supporting solar net metering — including Mumbai's BEST, Tata Power, Adani, Reliance, plus MSEDCL for rest of state. Mumbai's MMR + Pune's PMR have India's highest industrial tariffs, making commercial solar especially profitable.

Why Maharashtra MSMEs Get Best Commercial Solar ROI
Maharashtra has India's highest industrial electricity tariffs: ₹11-13/unit in MMR, ₹10-12/unit elsewhere. Combined with Section 32 depreciation, commercial solar payback is exceptional:
- Industrial 100 kW solar plant: ₹60L cost
- Section 32 depreciation (year 1): 40% × ₹60L = ₹24L · Tax saving: ₹6L
- Annual generation: 1.5 lakh units
- Annual saving (₹12/unit avg): ₹18 lakh
- Net payback after tax shield: 3 years
- 25-year warranty value: ₹4.5+ crore in saved electricity
Maharashtra's Industrial Solar Policy also allows open access for >100kW — meaning your solar plant can supply other industrial users in the state, creating an additional revenue stream beyond self-consumption.
