SolarSavingsMaharashtra is leading the rooftop solar revolution in India. If you are an MSEDCL (Mahadiscom) consumer, deploying a rooftop solar system can eliminate your monthly power bill entirely.
However, navigating the state's specific utility regulations requires clear steps. MSEDCL has structured processes for net metering applications, solar connection fees, and annual power credits. This guide breaks down the solar subsidy slabs available for Maharashtra homeowners, outlines the application process on the Mahadiscom portal, and explains how net metering billing works under the latest MERC (Maharashtra Electricity Regulatory Commission) rules.
1. Total Solar Subsidy Structure in Maharashtra
Under the national PM Surya Ghar Muft Bijli Yojana, homeowners in Mumbai, Pune, Nagpur, and rural Maharashtra qualify for direct central assistance. The subsidy is structured by the capacity (kW) of the solar system:
| System Sizing | Central Subsidy (CFA) | Average Installation Cost | Net Out-of-Pocket Cost |
|---|---|---|---|
| 1 kW System | ₹30,000 | ₹52,000 - ₹55,000 | ₹22,000 - ₹25,000 |
| 2 kW System | ₹60,000 | ₹1,02,000 - ₹1,08,000 | ₹42,000 - ₹48,000 |
| 3 kW System | ₹78,000 | ₹1,45,000 - ₹1,55,000 | ₹67,000 - ₹77,000 |
| 5 kW System | ₹78,000 (Capped) | ₹2,30,000 - ₹2,50,000 | ₹1,52,000 - ₹1,72,000 |
🏢 Group Housing & RWAs in Maharashtra
For housing societies (RWAs/GHS) registered in Maharashtra, the central government provides a subsidy of **₹18,000 per kW** for common area lighting and elevator loads, capped up to a maximum capacity of **500 kW** per society. This is highly effective for reducing shared maintenance bills.

2. Step-by-Step MSEDCL Solar Application Process
To secure your approvals, you must submit details to both the National Portal and the Mahadiscom local utility database. Follow this path:
- Log onto the National Rooftop Solar portal and submit your registration using your 12-digit MSEDCL consumer number.
- Your application is routed to the local MSEDCL sub-division. An inspector is assigned to perform a grid capacity audit.
- Once approved, you must select an empanelled installer licensed in Maharashtra. You can check local ratings in our Maharashtra Empanelled Vendor Directory.
- After system installation, pay the net-metering registration fee on the **Mahadiscom Web Portal** (typically ₹1,000 for single-phase, ₹3,000 for three-phase).
- MSEDCL field engineers will inspect the wiring, install the net meter, and activate the bidirectional connection.
- Track your final sign-off status using our PM Surya Ghar Status Tracker to ensure your DBT payout is released.
3. Understanding MSEDCL Net Metering Billing Rules
Maharashtra operates under net metering rules set by the state regulator (MERC). It is critical to understand how your billing credits are handled:
The Monthly Energy Ledger
Your monthly MSEDCL bill will detail three variables: **Import** (power pulled from the grid when the sun isn't shining), **Export** (solar power sent to the grid), and **Net consumption** (Import minus Export).
If your solar system exported 400 units and you consumed 300 units from the grid, your net billable units for that month will be **zero**. You will only pay the standard fixed customer charge and taxes (wheeling charges are not applied to exported units in Maharashtra).
The March Settlement Cycle
If you have surplus solar credits at the end of the month, they do not expire. They are carried forward to the next month's ledger.
However, at the end of the financial year (every **March 31st**), MSEDCL conducts a final settlement. Any remaining surplus units are bought by MSEDCL at their average power purchase cost (typically around ₹3.00 - ₹3.50 per unit) and credited to your bill, resetting your solar bank for the new fiscal year.
4. Project Costs and Payback Timelines in Maharashtra
Rooftop solar yields high returns in Maharashtra due to the state's high residential power tariffs. Homeowners consuming over 300 units per month are billed at higher slabs (often exceeding ₹10-12 per unit).
For a standard **3kW solar system** costing ₹1,50,000, subtracting the ₹78,000 government subsidy leaves a net cost of **₹72,000**. Generating approximately 360 units of solar energy per month saves you roughly ₹3,600 monthly (assuming a tariff of ₹10/unit).
This results in a payback period of **under 2 years** (20 months). To calculate your exact system size and payback timeline based on your current MSEDCL bill, use our interactive Rooftop Solar Cost Calculator.
