As India accelerates its transition to renewable energy, net metering has emerged as a pivotal mechanism for homeowners and businesses to harness the benefits of rooftop solar power. This comprehensive guide delves into the intricacies of net metering, its benefits, state-specific policies, and the application process, ensuring you are well-equipped to make informed decisions.
What is Net Metering?
Net metering is a billing arrangement that allows consumers with rooftop solar systems to export excess electricity back to the grid in exchange for credits. These credits offset the electricity consumed from the grid, leading to reduced energy bills.
How It Works:
- Solar Energy Generation: Your rooftop solar panels generate electricity during daylight hours.
- Exporting Excess Energy: Any surplus energy not consumed is sent back to the grid.
- Metering: A bi-directional meter records both the electricity consumed and the excess exported.
- Billing Credits: Credits are applied to your account, reducing future electricity bills.
Types of Net Metering in India
1. True Net Metering
Consumers receive full retail credit for the excess energy exported to the grid.
2. Net Billing
Excess energy is credited at a rate lower than the retail price, and the consumer is billed for the net consumption.
3. Virtual Net Metering
Credits from a single solar installation are distributed among multiple consumers, beneficial for housing societies and commercial complexes.
4. Aggregate Net Metering
Credits from multiple meters owned by the same entity are pooled together, often used in agricultural or large property settings.
Benefits of Net Metering
- Reduced Electricity Bills: Offset your electricity consumption by utilizing credits from exported solar energy.
- Environmental Impact: Contribute to a reduction in carbon emissions by promoting the use of renewable energy.
- Energy Independence: Decrease reliance on the grid, enhancing energy security.
- Encourages Renewable Energy Adoption: Financial incentives make solar energy more accessible and attractive.

State-wise Net Metering Policies in India (2025)
Delhi
- Eligibility: Residential, commercial, and industrial consumers.
- Incentives: Subsidies under the PM Surya Ghar Muft Bijli Yojana.
- Recent Developments: Over 10,000 rooftop solar connections added, leading to annual consumer savings of approximately ₹160 crore.
Maharashtra
- Recent Policy Change: MERC’s June 2025 order allows simultaneous net metering with open access for solar power, benefiting both new and existing systems.
- Nagpur’s Progress: Nagpur leads the state in rooftop solar adoption, with over 33,000 installations contributing to significant energy savings.
Kerala
- Proposed Amendments: Draft regulations propose limiting net metering to systems between 3 kW and 5 kW, with mandatory energy storage systems. This has raised concerns among stakeholders about potential hindrances to solar energy adoption.
How to Apply for Net Metering in India
- Eligibility Check: Ensure you have a valid electricity connection from the local Distribution Company (DISCOM).
- Application Submission: Fill out the online or offline net metering application form provided by your DISCOM.
- System Installation: Work with a certified solar installer to set up your rooftop solar system.
- Inspection and Approval: DISCOM will inspect the installation and, upon approval, install a bi-directional meter.
- Activation: Once the meter is installed, your net metering account will be activated, and you can start exporting excess energy.
Limitations and Challenges
- Availability: Not all DISCOMs offer net metering programs, and some regions have capped the number of participants.
- Credit Rates: In some cases, utility companies provide less than retail value for the excess energy, reducing the financial benefits.
- Seasonal Variations: Solar energy production varies with the seasons, which may impact the amount of excess energy generated.
- Grid Dependency: Net metering systems are still dependent on the grid, meaning they will not provide power during grid outages unless paired with battery storage.
Future Outlook
The Indian government continues to promote renewable energy adoption through various schemes and incentives. While some states are introducing regulatory changes, the overall trend indicates a growing commitment to solar energy. Staying informed about state-specific policies and technological advancements will be crucial for maximizing the benefits of net metering.
Conclusion
Net metering presents a significant opportunity for Indian homeowners to reduce electricity costs, contribute to environmental sustainability, and achieve energy independence. By understanding the mechanisms, benefits, and state-specific policies, you can make informed decisions about integrating solar energy into your home.

Frequently Asked Questions
What is net metering in simple words?
Net metering is a system where excess electricity generated by your solar panels is sent to the grid, and you earn credits that reduce your electricity bill.
How is a net metering bill calculated?
Your bill is calculated by subtracting the credits earned from excess solar energy exported to the grid from the electricity consumed. If you generate more than you use, the surplus is carried forward as credits (depending on state policy).
Can solar work without net metering?
Yes, solar panels can work without net metering. The electricity you generate will be consumed directly by your home, but any excess energy will go unused unless stored in a battery system.
What happens when I generate more power than I use?
The extra power is sent to the grid under net metering, earning credits. Without net metering, the excess energy may be wasted unless stored in batteries.
What is the difference between a solar meter and a net meter?
A solar meter measures only the electricity produced by your solar panels, while a net meter is bi-directional—it measures both the electricity your home consumes from the grid and the excess solar energy sent back to the grid.
