What net metering actually does to your bill
A net-metered connection records both what you import from the grid and what you export to it. Instead of dumping surplus generation, your daytime excess is credited and offsets units you draw at night.
This is what makes a grid-tied system without a battery viable: the grid becomes your storage. Your bill reflects the net position rather than gross consumption.
Eligibility basics
Requirements vary slightly by distribution company, but the common conditions are consistent across Pakistan.
- A three-phase connection is normally required for net metering.
- The sanctioned load must be adequate for the system size being installed.
- The connection should be in the applicant's name with no outstanding dues.
- Equipment must be from approved and certified categories, with an inverter that supports grid export.
The process, step by step
The sequence is predictable, and most delays come from paperwork rather than from the utility itself.
- Site survey and system design sized against your sanctioned load and consumption history.
- Installation and internal testing of the array, inverter and protection devices.
- Application submission with your CNIC, latest paid bill, equipment datasheets and single-line diagram.
- Technical inspection by the utility's team at your premises.
- Agreement signing and issuance of the licence.
- Installation of the bidirectional meter and commissioning of export.
Mistakes that delay approval
Almost every rejected or stalled file we have seen in Pakistan fails for one of a small number of avoidable reasons.
- System capacity requested above the sanctioned load on the connection.
- Name mismatch between the CNIC and the electricity connection.
- Missing or non-compliant inverter certification documents.
- Incomplete single-line diagram or earthing arrangement that fails inspection.
What to expect after the meter is installed
Once the bidirectional meter is live, read your first two bills carefully. You should see separate import and export readings and a net adjustment.
If export is showing zero while your inverter reports generation, that usually points at an inverter export setting or a meter configuration issue, not at your panels. It is fixable, and worth raising immediately rather than after several billing cycles.
Frequently asked questions
- Can I get net metering on a single-phase connection?
- Generally no. Most distribution companies require a three-phase connection for net metering, so a single-phase connection usually needs to be upgraded first.
- How long does approval take?
- When documentation is complete and the system matches the sanctioned load, the process moves in weeks rather than months. Incomplete files are the main cause of long delays.
- Do I still need a battery with net metering?
- Only if you want backup during outages. For bill reduction alone, net metering handles the surplus without any storage.
- What happens to unused export credit?
- Credit carries against your imports in the billing cycle, so it is worth sizing the system around your actual consumption rather than exporting a large permanent surplus.
