Understand how solar electricity connects with the grid, how energy import and export are measured, and how applicable billing arrangements work.
Generating electricity through solar panels gives households, businesses and industrial facilities greater control over their energy requirements. However, solar generation and electricity demand do not always occur at the same time.
A grid-connected solar system can use electricity generated on-site and, where authorized, send surplus electricity to the distribution network. When solar production is insufficient, electricity can be imported from the grid.
A bidirectional meter measures both directions of electricity flow. The financial treatment of exported electricity depends on the consumer's applicable agreement, tariff and regulatory framework.
Net metering is a mechanism historically used to account for electricity imported from the grid and surplus solar electricity exported back to it.
A bidirectional meter records imported and exported electricity separately. The readings help determine billing adjustments according to the terms of the applicable electricity agreement.
During daylight hours, a solar system generates electricity that can be used by the property. When generation exceeds immediate demand, eligible surplus electricity may flow into the utility grid.
At night or during periods of low solar production, electricity may be imported from the grid. The meter records both imported and exported units, allowing the utility to prepare bills under the applicable billing arrangement.
Pakistan's solar electricity billing framework has evolved. Under the NEPRA Prosumer Regulations, 2026, new prosumer arrangements generally use net billing, with imported electricity billed under the applicable retail tariff and exported electricity credited at the applicable purchase rate.
Certain existing agreements may continue under their previously approved metering and billing terms until their expiry, subject to the relevant regulations. Consumers should confirm their specific arrangement before estimating savings.
Grid-connected solar systems can help consumers make practical use of electricity generated on their own premises. Depending on system performance, consumption patterns and applicable billing arrangements, solar generation may reduce electricity expenses.
Local renewable electricity generation can also support cleaner energy use and reduce reliance on conventional power sources. Actual financial benefits vary with individual electricity demand, system size and tariffs.
Grid-connected solar systems that export electricity must meet applicable technical requirements and obtain the necessary approvals. The application process can involve documentation, system verification, interconnection assessment and metering arrangements.
Processing times depend on the applicable regulations, distribution company's procedures, documentation and technical conditions. Consumers should confirm current eligibility, approval requirements and billing terms with the relevant electricity provider before proceeding.

From solar system installation to meter activation, explore the key stages involved in setting up an approved grid-connected solar system.
The process begins with installing a grid-connected solar power system that meets the applicable technical and regulatory requirements for electricity export.
After installation, the required application documents and system details are prepared for submission to the relevant electricity distribution company.
The submitted application and solar installation undergo the applicable technical review and safety inspection. Required clearances are obtained before proceeding with grid interconnection.
Following the necessary approvals, the consumer completes the applicable agreement with the electricity distribution company, setting out the conditions for connecting the solar system to the grid.
The relevant authority reviews the submitted documentation and confirms that applicable regulatory and interconnection requirements have been fulfilled before final authorization.
After the required approvals, the distribution company completes the applicable metering arrangements. Once activated, the meter records electricity imported from and exported to the grid for billing purposes.
