Net metering · flats & societies
If you searched “virtual net metering” or “group net metering”, start here. Ordinary net metering credits one consumer number. Virtual / group arrangements try to share one rooftop across flats — only where your SERC and DISCOM actually offer it. Sealix is not your DISCOM.

Fast triage: Independent house, one meter? Use ordinary net metering. Flat / RWA sharing one terrace? Confirm DISCOM has a live virtual/group procedure in writing before capex. Need NOC / terrace rights first? Society NOC · Apartment solar · bill fit: free home check.
If you live in an independent house with one electricity connection, net metering is a familiar story: panels on your roof, a bi-directional meter, export credited against import on the same account. Apartments, group housing societies (GHS), and homes with multiple meters break that simple picture. Residents still want solar on the only large roof available — often the society terrace — while each flat pays its own DISCOM bill. That gap is where virtual net metering and group net metering enter the conversation, and where confusion causes expensive mistakes.
Generation and settlement happen on one consumer number. The person whose name is on the net-meter application owns the regulatory relationship with the DISCOM. Subsidy registration under PM Surya Ghar, inspection, and DBT typically follow that same account. For a standalone bungalow, that alignment is natural. For twelve flats sharing one terrace, it is politically and legally awkward unless the state has a sharing rule.
Under these frameworks — names and details differ by state — a solar plant is installed at a host location or on a designated meter, and a portion of the exported energy is virtually allocated to other meters in the same building or approved group. The electrons still flow through the local grid; the innovation is in billing software and the contract that tells the DISCOM how to split credits. A society might offset the common-area meter (lifts, STP, corridor lights, pumps) and optionally allocate shares to flats that opt in, usually after an RWA resolution and sometimes a tripartite agreement with the utility.
This is materially different from wiring every flat independently, which terrace area rarely allows, and different from expecting each flat to install its own small plant on a sliver of roof. The economic case for societies is often driven by common-area load — steady, visible on one bill — even when flat-level sharing is harder to negotiate.
India does not have one national “apartment net metering” button. The State Electricity Regulatory Commission publishes net-metering regulations; each DISCOM implements forms, inspection queues, and billing patches on its own timeline. Some utilities actively process group applications; others accept only standard single-consumer net meters and tell societies to register one “representative” flat — which may not match what residents want for fairness or subsidy.
Industry discussions often mention frameworks in Delhi, Maharashtra, and Rajasthan, among others, but citing a state is not permission to proceed. The operative question is: Does my DISCOM, today, have a published procedure and a billing code for virtual or group allocation on my exact premise type? Get that answer in writing — email or official circular reference — before the RWA commits lakhs in capex. If the answer is no, your options shrink to ordinary net metering on one meter, smaller per-flat systems where physically possible, or waiting — not forcing a vendor’s “we will manage” promise.
Most RWAs find common-area solar easier to justify than per-flat virtual credits. Common load is measured on one meter; savings show up in maintenance accounts everyone already scrutinises. Extending virtual credits to individual flat consumer numbers requires clarity on percentages, opt-in versus opt-out, and what happens when a flat is sold or rented. Document the split in the society resolution and mirror it in the DISCOM application — mismatches here are a common source of post-installation disputes.
Structural and legal steps overlap with any rooftop project: society NOC for solar, load and shadow study, empanelled vendor under PM Surya Ghar if you want CFA, ALMM-listed DCR modules, and net-meter inspection. Read apartment rooftop solar for terrace rights, water tank setbacks, and lift access — virtual metering does not remove those site constraints.
Some independent buildings run two or more consumer numbers — ground floor commercial plus first-floor residential, or a granny flat on a separate meter. A few states’ group rules contemplate related meters on the same plot; many do not. Do not assume parity with a housing society case. List every consumer number, tariff category, and sanctioned load, then ask the DISCOM whether a single plant can offset more than one. If not, the honest design may be two smaller systems or prioritising the meter with the highest unit consumption.
PM Surya Ghar central assistance is tied to eligible domestic rooftop plants registered correctly on pmsuryaghar.gov.in with post-commissioning DBT. A society plant may register against one host consumer number; whether and how participating flats benefit from CFA bands is a detail to verify on the live portal and with your state nodal agency — not from a generic article. Mismatch between portal data, Aadhaar, bill name, and bank account remains a top rejection reason even when net metering itself is approved.
If virtual or group rules are unavailable, the fallback is often registering the plant against one consumer number — sometimes the common-area account — and treating flat benefits as internal maintenance accounting rather than DISCOM-level virtual credits. That can still cut society bills meaningfully. Individual flat owners in the same building may install within their exclusive balcony or terrace rights where structurally allowed, each with standard net metering on their own meter — space-limited but legally clean.

Virtual net metering (sometimes called group net metering) lets electricity generated at one connection — often a society common-area meter or a designated host flat — be credited against other meters in the same premises or group, such as individual flat accounts. The solar plant is physically in one place, but the financial benefit is shared according to a formula your DISCOM accepts. It is not the same as ordinary net metering, where one consumer number owns both the rooftop array and the meter that receives export credits.
Ordinary net metering ties generation credits to the same consumer account that owns the plant. Virtual or group arrangements split or allocate those credits across multiple accounts — for example flats in a housing society — under rules published by the state regulator. Billing software, inspection steps, and the legal agreement between residents differ. PM Surya Ghar eligibility and CFA still apply to domestic rooftop systems, but the application must match how your DISCOM registers the plant and the meters it will offset.
No. Availability depends on your State Electricity Regulatory Commission and local DISCOM implementation. Some states have explicit group or virtual net metering regulations; others allow only standard single-meter net metering. Even within a state, not every DISCOM has live processes or trained staff for group billing. Confirm in writing from your DISCOM before signing a vendor contract or spending on a society-wide plant.
In jurisdictions that allow it, societies sometimes install solar on the clubhouse or unused terrace and allocate credits partly to the common-area meter (lifts, pumps, lighting) and partly to participating flats under an RWA resolution. The split must match DISCOM rules and the net-meter agreement. NOC, structural clearance, and empanelled vendor requirements still apply. See society NOC guidance and apartment rooftop solar basics before the general body votes on capex.
Central CFA under PM Surya Ghar is for eligible domestic rooftop grid-connected systems registered on the national portal with an empanelled vendor, ALMM-listed DCR modules, and post-commissioning DBT. Whether a group or virtual arrangement qualifies depends on how the plant is registered — typically one application tied to a host consumer number — and whether your state treats participating flats correctly in the subsidy workflow. Read the live portal rules and your DISCOM checklist; do not assume a society plant automatically gives every flat the full CFA band.
Regulations have appeared in several states over the years, with Delhi, Maharashtra, and Rajasthan among those often cited in industry discussions — but the operative document is always the current SERC order and your DISCOM's net-metering circular, not a blog summary. Names differ: group net metering, virtual net metering, or solar sharing for multi-unit buildings. Processes change. Ask your DISCOM for the latest application form and a worked example of how credits appear on two or more bills.
