Imagine a world where your electricity meter doesn’t just measure consumption — it measures income. This is exactly what India’s Solar Export Policy 2025 makes possible. Thanks to recent updates in the National Net Metering Guidelines by the Ministry of New and Renewable Energy (MNRE), homeowners can now sell excess solar power back to the grid and earn monthly income while reducing energy bills to zero.
The policy builds upon the success of the PM Surya Ghar: Muft Bijli Yojana (2024–2027), which brought rooftop solar to over one crore households. In 2025, India’s solar future has entered a new phase where every citizen is not just a consumer but also an energy producer — a “prosumer.”
This article breaks down how the Solar Export Policy 2025 works, what recent reforms mean for ordinary households, how different states are implementing buyer tariffs, and how you can start earning from your rooftop solar system today.
The Concept Behind Solar Export Policy 2025
What Is the Solar Export Policy?
The Solar Export Policy 2025 is an umbrella initiative under India’s National Solar Mission, integrating new Net Metering and Virtual Group Metering reforms to enable households, businesses, and housing societies to sell surplus power directly to DISCOMs (power distribution companies).
In simple terms:
- You install rooftop solar panels.
- Your system produces electricity.
- You use what you need, and send the leftover energy to the grid.
- The grid credits you (or pays you) for every extra unit exported.
Vision and Purpose
- Encourage Residential Adoption: Make rooftop solar financially lucrative.
- Ease Grid Pressure: Balance supply in high-demand urban areas.
- Enable Energy Democracy: Empower citizens to produce and profit from clean energy.
- Meet India’s 500 GW Target: Help India reach its renewable energy goal by 2030.
The policy ties directly into India’s broader clean energy architecture, including the Green Credit Programme, Smart Cities Mission, and Solar for All Mission.

How Solar Export Works: Understanding Net Metering
The backbone of the Solar Export Policy lies in an updated Net Metering system.
What Is Net Metering?
Net metering allows solar users to send unused electricity from their rooftop back to the local DISCOM grid. Your electricity bill reflects the net difference between your consumption and your production:
Bill=Electricity Consumed−Electricity Produced
Bill=Electricity Consumed−Electricity Produced
If you produce more than you consume, those surplus units are carried forward as credits or converted into cash payments based on predefined export rates.
Key 2025 Net Metering Reforms
According to MNRE’s National Guidelines on Net Metering, August 2025, here’s what has changed :
| Aspect | 2025 Update | Benefits |
| Eligibility | Systems up to 500 kW or sanctioned load, whichever is lower | Broader inclusion for homes and small businesses |
| Export Tariffs | ₹3.50–₹5.00 per unit depending on state | Higher earnings for surplus producers |
| Billing Cycle | Monthly compensation + yearly settlement | Faster payouts |
| ALMM Waiver Window | Until August 2025, homeowners can choose local solar modules | Reduced equipment cost |
| Virtual Net Metering (VNM) | Credits transferable across multiple rooftops | Perfect for apartments & gated societies |
| Group Net Metering (GNM) | Shared ownership models now legal nationwide | Common solar systems for multiple consumers |
Example
If your home solar system produces 500 units per month, and you consume only 300 units, the remaining 200 units go to the grid.
- Suppose the discharge rate is ₹4 per unit → you earn ₹800 that month.
- Over a year, that’s ₹9,600–12,000 in additional income.
Gross Metering Option: Sell All Energy to the Grid
Some consumers choose gross metering, where the household sells 100% of generated electricity to the grid instead of using it partially.
- Common among institutions, schools, or apartment complexes.
- Rates vary between ₹3.5–₹6.0/unit depending on region.
- Suitable when daytime occupancy (and power usage) is low.
Gross metering works like a small business selling power rather than offsetting usage.
National Tariff Guidelines under Solar Export Policy
The Energy Regulatory Commissions (CERC and SERCs) determine solar export tariffs based on cost of generation, grid draw, and regional demand.
| State | 2025 Solar Export Rate (per Unit) | Remarks |
| Delhi | ₹4.50 | Full bill offset + income payout |
| Maharashtra | ₹4.20 | Optional banking for peak hours |
| Tamil Nadu | ₹3.90 | Time-of-Day tariff integration |
| Gujarat | ₹4.75 | Highest producer credit in India |
| Rajasthan | ₹4.00 | 100% residential inclusion |
| Uttar Pradesh | ₹3.80 | Up to 2 MW residential limit |
| Karnataka | ₹3.86 | Virtual Net Metering Pilot |
| Haryana | ₹4.25 | Group Net Metering approved |
| Punjab | ₹4.10 | Industrial encouragement policy |
These credits are reflected as direct cash or DISCOM bill deductions as per consumer choice.
Policy Integration: Solar Export Meets PM Surya Ghar
Double Advantage: Subsidy + Export Income
Under the PM Surya Ghar: Muft Bijli Yojana, you can claim up to ₹78,000 subsidy for installing a solar rooftop system. Now, Solar Export Policy ensures that once you generate power:
- You save money on self-consumption bills.
- You earn from surplus sale to grid.
Example Calculation:
| Parameter | Value |
| System Size | 5 kW |
| Generation Output | ~600 units/month |
| Household Usage | 350 units/month |
| Export Surplus | 250 units |
| Selling Rate | ₹4.25/unit |
| Monthly Credit | ₹1,062 |
| Annual Earning | ₹12,700+ |
| Subsidy Received | ₹78,000 |
| Payback Period | ~4 years |
Within four years, your system’s total installation cost is recovered — after that, you earn profit for over 20 years.
