Solar Net Metering in Pakistan: A Complete Consumer Guide

Net metering allows solar panel owners in Pakistan to sell surplus electricity back to the national grid and receive credits that reduce their monthly bills. Since NEPRA introduced the Distributed Generation and Net Metering Regulations in 2015 — updated in 2023 — the program has expanded to cover hundreds of thousands of systems across all DISCOs. If you are paying high electricity bills in summer, a properly sized solar system with net metering can dramatically reduce or even eliminate your bill.

This guide covers how net metering works under Pakistan's current regulatory framework, who can apply, what the application process involves, and how to read the new bill format once your system is approved.

How Solar Net Metering Works in Pakistan

When your solar panels generate more electricity than your home or business is consuming at that moment, the surplus flows out through your meter into the grid. A bi-directional (net) meter records both the energy you import from the grid and the energy you export to it. At billing time, the DISCO subtracts your exported units from your imported units. If you exported more than you imported in a given month, the surplus is carried forward as a credit to the next billing cycle.

Under NEPRA's current net metering framework, the export rate and import rate are not identical for most consumers — the buyback rate for exported units is set at a reference tariff determined by NEPRA, which may be lower than the full consumer tariff you pay for imports. Your bill will clearly show imported units, exported units, and the resulting net charge or credit.

• Solar panels generate DC electricity during daylight hours
• An inverter converts DC to AC for home use; surplus flows to the grid through your bi-directional meter
• Your meter records both import (grid → home) and export (home → grid)
• Monthly bill: import units minus export units = net consumption
• Surplus credits carry forward to future bills; annual settlement handles any unclaimed surplus

Who Qualifies for Net Metering in Pakistan

Any electricity consumer who already has a valid DISCO connection can apply for net metering, regardless of whether you are domestic, commercial, or industrial. The system size you can install is limited to your sanctioned load — a consumer with a 10 kW sanctioned load can install a net-metered solar system of up to 10 kW peak capacity. Larger systems require a sanctioned load increase first.

NEPRA requires the solar system to be installed by an approved distributed generation company (DG company) — a list of licensed installers is available on NEPRA's website. Using an unlicensed installer can result in your net metering application being rejected. The equipment itself (panels, inverter) must also meet NEPRA's technical specifications, which your licensed installer should handle.

The Net Metering Application Process Step by Step

The application process involves both your chosen solar installer and your DISCO. It has become more streamlined since 2023 but still requires several formal steps:

• Choose a NEPRA-licensed distributed generation company to design and install your system
• Get a site survey and system sizing recommendation from the installer
• The installer submits the net metering application to your DISCO on your behalf — you provide your reference number, CNIC, and connection documents
• The DISCO reviews the application and may conduct a technical inspection of the site
• If approved, the DISCO schedules a bi-directional meter installation (replacing your existing meter)
• After meter installation and interconnection testing, the system is energized and net metering begins
• The first net metering bill typically arrives in the next regular billing cycle — verify it shows both import and export readings

How to Read Your Net Metering Electricity Bill

A net metering bill looks different from a standard electricity bill. It shows two sets of meter readings: 'Export' (units sent to grid) and 'Import' (units consumed from grid). The net consumed units for billing purposes is Import minus Export. If the net figure is positive, you pay for those units at the applicable tariff. If it is negative (you exported more than you imported), the credit carries forward to the next billing cycle.

Other charges — GST, FPA, meter rent, and TV licence fee — may still appear on a net metering bill even when your net energy charge is zero, because some charges are fixed regardless of consumption. Check your DISCO's net metering billing schedule to understand exactly which charges remain fixed.

Financial Reality: What to Expect from Net Metering Savings

A well-sized solar system in Pakistan can eliminate most or all of the energy charge on a summer bill — the largest component. However, fixed charges (meter rent, licence fees) and GST on those fixed charges remain regardless of solar generation. Most households see their summer bills drop by 60–90% and their winter bills drop by 30–60%, depending on system size, orientation, and shading. A 5 kW system on a south-facing rooftop in Lahore or Multan typically generates 550–650 units per month in summer.

The investment payback period depends on your current bill size and system cost. A household paying Rs. 15,000–25,000 per month in summer bills can typically recover a 5 kW system cost in 3–5 years, with a 25-year panel lifespan providing savings long after payback. Net metering makes the investment viable because you are credited for every unit you cannot self-consume rather than losing it.
