Understanding Pakistan's Solar Policy 2026

In February 2026, NEPRA transitioned Pakistan from "Net Metering" to a **"Net Billing"** framework. This change significantly impacts how solar owners are compensated for the energy they send back to the grid.

Key Changes in 2026

  • Unit-for-Unit is Gone: Previously, 1 unit exported canceled 1 unit imported. Now, exports are bought by the DISCO at a fixed low rate (~Rs. 10.50).
  • Self-Consumption is King: Because you import power at Rs. 50+ but sell it at Rs. 10.50, the most profitable strategy is to use as much solar power as possible during daylight hours.
  • The Hybrid Shift: Many users are now opting for Battery storage (Hybrid systems) to store daytime excess for nighttime use, rather than exporting it at a low price.

How this Calculator Works?

Our tool uses the latest **2026 NEPRA Net Billing slabs**. It calculates your ROI based on your city's average sunlight hours and your self-consumption ratio. If you use ACs during the day, your payback period will be much shorter compared to a household that is empty during the day.

Frequently Asked Questions

Yes, but the 'payback period' has increased from 2.5-3 years to 4-5 years for most residential users. It remains the best defense against rising grid tariffs.
The current national average energy purchase price for solar exports is approximately Rs. 10.50 per unit.
With Net Billing, batteries (Hybrid systems) are becoming more viable as they allow you to 'save' your Rs. 50+ units instead of 'selling' them for Rs. 10.50.
