Understanding Solar Subsidy in Kolkata: The Big Picture
4.1 What is the PM Surya Ghar: Muft Bijli Yojana?
The PM Surya Ghar: Muft Bijli Yojana is the Government of India’s flagship residential rooftop solar scheme, launched to provide free electricity to households through solar power. In February 2024, the Union Cabinet approved a massive ₹75,021 crore total subsidy outlay for this scheme — making it one of the largest renewable energy subsidy programs in India’s history.
4.2 Why Kolkata Homeowners Must Act Now
-
DISCOM: Only WBSEDCL-registered consumers are eligible for PM Surya Ghar subsidy (CESC consumers have a separate process)
-
Solar potential: Kolkata receives 4.5-5 kWh/m² of daily solar radiation — more than enough for viable rooftop solar
-
Installed capacity: West Bengal has already crossed 30 MW of rooftop solar, with aggressive expansion targets by 2030
4.3 How the Subsidy Structure Works
Table
| System Capacity | Subsidy Rate | Total Subsidy |
|---|---|---|
| 1 kW | ₹30,000 per kW | ₹30,000 |
| 2 kW | ₹30,000 per kW | ₹60,000 |
| 3 kW | ₹18,000 per kW (additional) | ₹78,000 |
| 4 kW & above | No additional subsidy | ₹78,000 (capped) |
Critical point for Kolkata buyers: Whether you install 3 kW, 5 kW, or 10 kW — the maximum subsidy remains ₹78,000. The first 2 kW get ₹30,000/kW, the 3rd kW gets ₹18,000, and anything beyond gets zero additional subsidy.

As per MNRE guidelines, your solar installer must be empanelled with WBSEDCL to make you eligible for subsidy. Here are some of the WBSEDCL-empanelled vendors operating in Kolkata:
Net Metering in Kolkata: How It Works with Your Subsidy
9.1 What is Net Metering?
9.2 How Net Metering Works in Kolkata
Table
| Time of Day | Solar Generation | Your Consumption | Grid Interaction |
|---|---|---|---|
| Morning (6 AM – 10 AM) | 2-4 units | 3-5 units | Draw from grid |
| Midday (10 AM – 4 PM) | 12-18 units | 4-6 units | Export excess to grid → earn credits |
| Evening (4 PM – 10 PM) | 0 units | 8-12 units | Draw from grid, use credits first |
| Night (10 PM – 6 AM) | 0 units | 2-4 units | Draw from grid |
-
Monthly generation: 350 units
-
Monthly consumption: 330 units
-
Excess exported: 20 units = ₹200 credit
-
Next month’s bill reduced by credit amount
9.3 Net Metering Application Process
-
Your installer submits net metering application along with system design
-
WBSEDCL approves and schedules net meter installation
-
Bi-directional meter is installed (measures both import and export)
-
Post-commissioning, net metering is activated
