Solar Net Metering Pakistan Feb 2026 Deadline — Rs.25.32 vs Rs.8.13 Tariff Explainer
What changes for Pakistani solar net-metering after Feb 2026?
Two NEPRA tariff bands now exist: Rs.25.32/unit export rate for solar systems commissioned BEFORE Feb 2026 (legacy NEPRA tariff, locked for the remaining contract years), and Rs.8.13/unit export rate for systems commissioned AFTER Feb 2026 per the new SRO. This is a 3× cut for new installs. Lock-in for legacy users typically runs through the original 7-year net-metering license — verify your specific commissioning certificate. For new installs, the payback math has shifted: bigger battery + self-consumption strategy beats grid-export.
The two tariff bands side-by-side
| Aspect | Pre-Feb 2026 install | Post-Feb 2026 install |
|---|---|---|
| Export rate | Rs. 25.32/unit (or NEPRA reference) | Rs. 8.13/unit |
| Lock-in period | 7 years from commissioning | 7 years (new contract) |
| Payback for 10kW system | ~3.5-5 years | ~6-9 years |
| Best strategy | Maximise export, minimise battery | Maximise self-consumption + battery |
| Hybrid inverter needed? | Optional (grid-tie OK) | Strongly recommended |
| Battery size | Optional 5 kWh | Mandatory ROI driver — 10-15 kWh |
The payback math
Pre-Feb install (legacy):
- 10 kW system: PKR 1,400,000 turnkey
- Generates ~16,000 units/year. Self-use ~50%, export ~50%.
- Self-use saves: 8,000 × Rs. 50 (unit cost avoided) = Rs. 400,000/year
- Export earns: 8,000 × Rs. 25.32 = Rs. 202,560/year
- Total saving: ~Rs. 600,000/year. Payback: ~2.3 years on the system minus battery.
Post-Feb install (new SRO):
- 10 kW system + 10 kWh battery: PKR 2,200,000 turnkey
- Generates ~16,000 units/year. Self-use ~80% (battery shifts night load), export ~20%.
- Self-use saves: 12,800 × Rs. 50 = Rs. 640,000/year
- Export earns: 3,200 × Rs. 8.13 = Rs. 26,000/year
- Total saving: ~Rs. 666,000/year. Payback: ~3.3 years on system+battery.
Conclusion: battery + self-consumption math wins under the new SRO. Grid-tie-only without battery has 6-9 year payback under Rs. 8.13/unit export — too slow.
Compliance + transition rules
- "Commissioning" = NEPRA acceptance + meter swap date, not the order date or the install date. Get the DISCO meter-swap certificate signed before Feb 2026 deadline.
- System size matters for tariff slab — up to 25 kW residential is one slab, 25-100 kW commercial is another. Check exact NEPRA tariff bands at time of application.
- Pre-Feb systems CANNOT be expanded at the legacy rate — any added capacity must be commissioned on the new contract.
- Net-metering license renewal after 7 years moves to whatever the prevailing tariff is at renewal time.
- Inverter must be on NEPRA-approved list — verify with your DISCO before purchase.
If you missed the Feb 2026 deadline — your best strategy
- Increase self-consumption — shift discretionary load (water pump, AC pre-cool, EV charging) into solar daytime hours. Smart-home WiFi switches help.
- Add a battery — 10-15 kWh LiFePO4 to absorb daytime excess and serve night-time load.
- Switch to hybrid inverter — if your current inverter is grid-tie-only, hybrid lets you store excess instead of exporting at low rate.
- Bigger array, smaller export — oversize the array to cover almost all self-consumption + small unavoidable export. Don't size for export-heavy.
- ToU shifting — if on K-Electric ToU, charge battery during peak 5-11 PM, discharge during peak. Battery arbitrage of Rs. 40-60/unit value.
