Solar ROI

Understanding Pakistan's Solar Policy 2026

In February 2026, NEPRA transitioned Pakistan from the traditional "Net Metering" policy to a **"Net Billing"** framework. This change significantly alters how solar system owners are compensated for the excess energy they export back to the grid.

Key Changes in 2026

• Unit-for-Unit is Gone: Previously, 1 unit exported canceled out 1 unit imported. Under Net Billing, exports are bought by the DISCO (LESCO, K-Electric, IESCO, etc.) at a fixed flat rate (~Rs. 10.50 per unit).
• Self-Consumption is Critical: Since you import power at Rs. 50+ but sell it at Rs. 10.50, the most profitable strategy is to consume as much solar power as possible directly during daylight hours (e.g. running ACs).
• The Hybrid Storage Shift: Many users are shifting from on-grid to hybrid systems by adding batteries. Storing excess daylight power to use at night saves imports at Rs. 52+/unit, yielding far higher savings than exporting at Rs. 10.50.

How this Calculator Works?

Our tool computes your ROI using the latest **NEPRA Net Billing parameters**. It takes your average bill, estimates your consumption profile, recommends the optimal system size, and calculates your break-even period based on actual sunlight factors across different regions.
