Navigating power tariffs and utility regulations in Pakistan can feel overwhelming, especially with ongoing policy shifts from NEPRA and LESCO (Lahore Electric Supply Company). For property owners looking to eliminate heavy electricity bills, staying informed on current grid regulations is crucial to designing an efficient system.
With 9 years of experience completing over 500+ solar installations across Lahore, GetSolar.com.pk has guided hundreds of clients through evolving utility policies. Here is your definitive guide to understanding net metering, net billing, and how to maximize your solar payback period under current LESCO rules.
What Is the Difference Between Net Metering and Net Billing?
While both frameworks allow you to offset grid power with rooftop solar, they handle surplus energy generation differently:
-
Net Metering (Traditional 1:1 Offset): Surplus energy exported to the grid is credited unit-for-unit against units imported during off-peak hours.
-
Net Billing (Buy-Sell Framework): Energy imported from LESCO is billed at the retail tariff rate, while excess units exported back to the grid are credited at a designated generation rate.
Because exported electricity yields a different value than imported electricity, system design must focus heavily on daytime self-consumption rather than simply generating massive excess power to sell back to the grid.
Key LESCO Net Metering Application Requirements
To connect a grid-tied or hybrid solar system to the LESCO grid, your property and system design must satisfy specific technical standards:
-
Sanctioned Load Matching: Your total solar inverter capacity cannot exceed your sanctioned load listed on your monthly LESCO bill.
-
Transformer Capacity Limits: Local distribution transformers have capped capacity limits for solar input. Early application submission ensures your phase is approved before transformer capacity fills up.
-
Approved Inverter Models: Only NEPRA-certified, grid-tied inverters equipped with compliant anti-islanding and grid protection settings qualify for green meter installation.
-
Three-Phase Connection: Net metering requires a three-phase electrical meter setup at the premises.

Maximizing Your ROI: Daytime Self-Consumption Strategy
Under modern billing structures, the primary key to achieving a fast 2.5 to 3.5-year ROI is running heavy appliance loads during daylight hours.
-
Schedule Heavy Loads During Peak Sun Hours (10 AM – 4 PM): Run inverter ACs, water pumps, washing machines, and electric vehicle chargers directly off solar power.
-
Avoid Unnecessary Grid Import: Consuming solar power live at the moment of generation saves you the full retail tariff cost per unit.
-
Right-Size System Capacity: Sizing your system according to daytime consumption prevents over-investing in panel capacity that produces unneeded surplus.
