What Is Solar Net Metering? Meaning, Working & Benefits
Are you trying to find ways to save money on your electricity bill? Solar net metering can help. If you have installed an on-grid solar system at your home, there will be times when your panels generate more electricity than you actually use. With net metering, you can send that extra power back to the grid, and in return you earn credits on your electricity bill.
This makes your solar energy far more valuable. You not only save on power, you also get rewarded for the surplus your rooftop produces. In 2026, net metering continues to be the backbone of rooftop solar savings in India, and it is what makes schemes like PM Surya Ghar so worthwhile.
Keep reading as we explore what solar net metering means, how it works, the different types, the current rules in India, and the benefits you can expect. Whether you already have solar panels at home or are planning to install them, this guide is for you.
What is Net Metering?
Net metering is a billing system that gives you credit for the surplus electricity your rooftop solar system sends back to the grid. When your panels generate more power than your home or business is using, that extra electricity flows to the grid, and your utility credits it against the electricity you draw back later.
In simple terms, the grid acts like a giant battery. During the day, when your solar panels produce more than you need, you “deposit” the surplus. At night or on cloudy days, when your panels are not producing enough, you “withdraw” using those credits, without paying extra for that portion. A special bidirectional meter (also called a net meter) tracks both the electricity you import from the grid and the electricity you export to it, and you are billed only on the net difference.
This arrangement lowers your electricity bills and supports the wider use of clean, renewable energy.
How Does Net Metering Work?
The process behind net metering is straightforward and designed to make solar power efficient and rewarding. Here is how it works:
- Solar generation: Your rooftop panels generate electricity during daylight hours.
- Self-consumption: Your home or business uses this electricity first, directly, as it is produced.
- Exporting surplus: Any electricity you do not use at that moment is sent back to the grid.
- Earning credits: Your bidirectional net meter records the exported units, and your DISCOM (electricity distribution company) credits them to your account.
- Using credits: When your panels are not generating enough, such as at night, you draw power from the grid, and your earlier credits offset those units.
In short, net metering lets you balance your energy use across the day by using the grid to store the value of your surplus solar.
How Do Electricity Bills Work with Net Metering?
The credits you earn through net metering directly reduce your electricity bill. At the end of your billing period, the units you exported are subtracted from the units you imported, and you pay only for the net units consumed.
If your consumption is higher than your generation, you pay for the difference at your normal tariff. If your generation exceeds your consumption, the surplus credits usually roll over to the next billing cycle, and any unused surplus at the end of the settlement period (often a year) is settled according to your state’s net metering policy, either paid out at a set rate or carried forward, depending on the DISCOM.
This system not only promotes renewable energy but also helps you plan and balance your future energy needs.
Types of Net Metering
“Net metering” is often used as a catch-all term, but there are a few different metering models in India, and the one you get affects your savings. Here is how they compare:
| Model | How it works | Best for |
|---|---|---|
| Net metering | You are billed only on the net (imports minus exports); surplus is credited, usually near your retail tariff | Most residential rooftop owners |
| Gross metering | All your solar generation is exported and sold to the DISCOM at a fixed feed-in tariff; you buy all your consumption separately | Cases where the feed-in rate is attractive |
| Net billing / net feed-in | You self-consume your solar, and exported surplus is paid at a separate (usually lower) rate, not full retail | Larger systems in some states |
| Virtual net metering (VNM) | One solar plant’s output is shared across several electricity accounts, such as flats in a housing society | Apartments and group housing |
| Group net metering | One owner offsets several of their own connections using a single system | Owners with multiple meters |
For most homeowners, net metering gives the best value, because your surplus is credited at or close to the rate you would otherwise pay. Virtual and group net metering have made solar practical for apartment residents who cannot install a system of their own, by letting multiple families share one rooftop plant.
Benefits of Net Metering
Beyond the solar subsidy you can claim when installing panels, net metering brings several clear benefits:
- Lower electricity bills: You pay only for the net power you draw from the grid.
- Earn credits for surplus: Your extra solar generation is not wasted, it becomes bill credit.
- Grid power whenever needed: You can still draw from the grid at night or when your system underproduces.
- Faster payback: By monetising your surplus, net metering shortens the time it takes your system to pay for itself.
- Eco-friendly: You reduce your carbon footprint and support clean energy.
- Automatic once set up: After your system is connected and the net meter is installed, it all works in the background.
Net Metering Rules and Policies in India (2026)
Yes, India has clear net metering rules that let you connect your rooftop solar to the grid and earn credit for surplus power. The framework comes from the Electricity (Rights of Consumers) Rules and is implemented by each state’s regulator (SERC) and DISCOM, which is why the exact limits vary from state to state.
Here is the current picture in 2026:
- Net metering is generally available for rooftop systems up to the sanctioned load, and for residential systems it is widely supported, with small systems (around 10 kW and below) being the most straightforward to approve.
- Capacity limits vary by state. For example, several states allow net metering up to 500 kW or 1 MW, while some cap residential net metering lower. Always check your own DISCOM’s current limit.
- PM Surya Ghar installations are grid-connected with net metering, which is what lets subsidised residential systems export surplus and earn credits.
- Proposed 2026 changes: draft amendments under discussion (such as proposals around battery storage for very large prosumers and gross metering for some new larger systems) are still at the draft stage and not yet notified, and existing net metering consumers are expected to be grandfathered under their current terms.
Because the specifics, capacity caps, export rates, and settlement, differ by state and are periodically updated, the safest approach is to confirm the latest rule with your DISCOM or a registered installer before sizing your system.
Eligibility and Requirements for Net Metering in India
To join a net metering programme in India, you generally need to meet these conditions:
- You are a residential, commercial, industrial, or institutional consumer with a valid electricity connection from your local DISCOM.
- You own or legally occupy the premises where the solar system will be installed.
- Your solar system’s capacity does not exceed your sanctioned load, and fits within your state’s net metering capacity limit.
- The system meets the technical standards set by the Central Electricity Authority (CEA) and your DISCOM, and uses approved (ALMM-listed) equipment where required for subsidy.
If you meet these conditions, you can use net metering to cut your electricity bills by generating your own solar power. You can contact our solar experts to check whether you are eligible for net metering in your area.
On-Grid Solar and the Net Meter
Net metering goes hand in hand with an on-grid solar system. An on-grid system has no battery; it works directly with the grid, sending surplus to it by day and drawing from it when needed. The bidirectional net meter is what makes this two-way exchange possible and measurable. This is why on-grid solar with net metering is the most cost-effective choice for most Indian homes, it avoids the cost of batteries while still giving you the full value of your generation through credits.
How to Apply for Net Metering in India
You can set up net metering smoothly by choosing a reputed, empanelled solar installer. The process generally runs like this:
- Your installer surveys your roof and designs a system within your sanctioned load.
- You apply for net metering through your DISCOM (or the PM Surya Ghar portal for subsidised residential systems).
- The DISCOM grants technical feasibility approval.
- The system is installed with ALMM-listed panels.
- The DISCOM inspects the system and installs the bidirectional net meter.
- Your net metering goes live, and credits begin appearing on your bill.

Frequently Asked Questions
1. What is net metering in solar, in simple terms?
Solar net metering is a billing system where the surplus electricity your rooftop panels send to the grid is credited to your account. A bidirectional meter measures what you import and export, and you are billed only on the net difference, which lowers your electricity bill.
2. How does solar net metering work?
Your panels generate power by day; you use what you need, and the surplus flows to the grid and earns credits. At night or when your panels underproduce, you draw from the grid and your credits offset those units. The net meter tracks both directions automatically.
3. What is the difference between net metering and gross metering?
Under net metering, you are billed only on the net of your imports and exports, so you effectively get near-retail value for your surplus. Under gross metering, all your solar output is sold to the DISCOM at a fixed feed-in rate, and you buy all your consumption separately. Net metering is usually more rewarding for homes.
4. What is virtual net metering?
Virtual net metering lets several electricity accounts share the output of one solar plant, which is ideal for apartments and housing societies where residents cannot each install their own rooftop system. Group net metering similarly lets one owner offset multiple connections with a single system.
5. What is the net metering capacity limit in India?
It varies by state. Net metering is generally available up to your sanctioned load, with many states allowing up to 500 kW or 1 MW and some capping residential systems lower. Because limits and rules are set by each state’s regulator and are periodically revised, confirm the current limit with your DISCOM.
6. Does net metering work with an on-grid solar system?
Yes. Net metering is designed for grid-connected (on-grid) systems. The bidirectional net meter enables the two-way exchange of power with the grid, which is why on-grid solar with net metering is the most cost-effective option for most homes.
7. How are my credits settled?
Surplus credits usually carry forward to the next billing cycle. Any unused surplus at the end of the settlement period (commonly a year) is settled according to your state’s policy, either paid out at a set rate or adjusted, depending on your DISCOM.
8. Is net metering available for PM Surya Ghar subsidy systems?
Yes. PM Surya Ghar residential rooftop systems are grid-connected with net metering, which is what allows them to export surplus and earn credits while also qualifying for the central subsidy.
