If you’re planning to install a rooftop solar system in Pakistan or already have one, understanding NEPRA’s solar buyback rate — and how it’s changed — is essential for estimating your return on investment (ROI), monthly savings, and long-term profits. In 2026, Pakistan’s solar net metering framework has fundamentally changed. Regulators have moved away from traditional net metering to a net billing / gross metering model, sharply affecting how solar export units are compensated.
This article explains:

- The latest official rate for Pakistan
- How net metering used to work vs today’s net billing
- Real exports vs billing impact

What Is NEPRA Solar Buyback Rate in Pakistan?
The NEPRA solar buyback rate is the price per unit (PKR) that power distribution companies (DISCOs) pay consumers for exporting surplus solar electricity back to the grid. It’s a key part of net metering / net billing policy — a mechanism that compensates homeowners and businesses for excess solar units they supply to the national grid.
The regulator behind this rate is the National Electric Power Regulatory Authority (NEPRA), Pakistan’s official energy regulator.

###New Rate for New Solar Owners (2026)
Under the recently notified Prosumer Regulations 2026, NEPRA has effectively ended classic net metering and shifted to net billing / gross metering.
This means:
- New solar owners exporting excess electricity will be paid roughly Rs. 8–11 per exported unit. The widely discussed price float is around Rs. 11/unit, depending on the final tariff framework being implemented.
🔹 This is a significant drop from earlier net meter compensation.
🔹 Export credits are no longer equal to import units consumed.
Existing Solar Owners
If you already have a registered net metering agreement, your exported units are still being bought at Rs. ~25.9 per unit — but this protection applies only for the duration of your existing contract. Once it expires, you will likely move to the new net billing rate.

How Net Metering Worked (Old) vs Net Billing (New)
Old System (Net Metering)
- One unit exported = one unit credit against imported units
- Ex: export 100 units, offset 100 imported units
- Billing quarter adjusted based on net exchange
Result: Solar consumers could reduce bills significantly, often to near zero.
This system boosted solar adoption rapidly.
New System (Net Billing / Gross Metering)
Key changes:
- Exported units are purchased separately at the buyback rate.
- Imported grid units are charged at retail tariff (higher than buyback).
- No 1:1 offset — you are paid only for surplus units exported and still pay full price for what you import.
Example:
- Solar exports 100 kWh → get paid ~Rs. 11 × 100 = Rs. 1,100
- Import grid electricity 100 kWh → pay ~Rs. 45 × 100 = Rs. 4,500
- Net bill = Rs. 3,400 (you still pay a bill despite exporting solar!)
This reversal dramatically changes the ROI math.
Solar Buyback Rate vs Electricity Import Rate (Why It Matters)
- Buyback Rate ~Rs. 10–11/unit (export)
- Grid Import ~Rs. 40–50/unit (peak retail)
This creates a large imbalance — your exported units are valued much lower than what you pay for the electricity you import. Earlier net metering allowed one-for-one offsetting, offering zero bills or positive credits in many homes. That advantage is now minimized.
How Much Can You Earn from Solar Buyback? (Sample Calculation)
Let’s model a typical rooftop solar user in Lahore or Islamabad:
- Installed capacity: 5 kW
- Average daily solar generation: 20–25 kWh
- Monthly surplus (export): 100 kWh
- Current buyback rate: Rs. 11/unit
Earnings from export:
100 × Rs. 11 = Rs. 1,100/month
Savings still come mainly through self-consumption:
If you use 70% of your own solar and reduce imports, you save ~Rs. 40–50 × 70 = ~Rs. 2,800–3,500 monthly.
Total monthly benefit ≈ Rs. 4,900–6,600
(This excludes financing cost and loan interest)*
⚠ Payback period increases compared to old net-metering math — more emphasis on self-consumption and batteries.
NEPRA Net Metering Rules & Policy (Essentials)
These changes stem from:
- NEPRA Prosumer Regulations 2026 — fully notified policy changing billing mechanism.
- Economic Coordination Committee (ECC) decisions from March 2025 that cut buyback to ~Rs. 10 for new users.
👉 Key rules today:
- New installations will attract net billing, not net metering
- Export credits paid at a fixed buyback tarif
- Existing net metering agreements protected until expiry
- Contract duration reduced from 7 years to 5 years for new agreements
- Monthly settlement replaces quarterly adjustments
- Distributed Generation Regulations 2015 being phased out
These policies aim to reduce the financial burden on grid consumers while still encouraging solar adoption — albeit with lower export incentives.

Factors Affecting Solar Buyback Rate
- Several factors influence the rate you effectively get:
- Regulatory framework shifts (net billing vs net metering)
- DISCO tariff structure (peak/off-peak pricing)
- National Average Power Purchase Price (NAPP) vs National Average Energy Purchase Price (NAEPP)
- Solar generation capacity & actual self-consumption
- Quarterly settlement formulas
- Policy shifts by NEPRA and Finance Division
All these mean the value of exported solar units changes not just by rate but by how much you import.
Is Net Metering / Solar Still Worth It in Pakistan?
Yes — but with caveats.
But exporting solely for income?
With a buyback rate now near Rs. 8–11/unit, profits from exported units alone are significantly lower than before. This pushes many consumers to rethink system sizing and hybrid setups.
Industry users and solar investors must recalculate payback periods based on net billing, not net metering — leading to longer returns than the classic 2–4 years estimate of the past.

Final Recommendations (2026 Solar Strategy)
If you plan to invest in solar today:
- Prioritize self-consumption optimization (batteries + load shifting)
- Size your system based on usage, not maximum export
- Re-estimate ROI using the new buyback rate, not old net-metering math
- Consider hybrid systems to balance usage and grid dependency
- Monitor future NEPRA revisions — this policy is evolving
