For nearly a decade, rooftop solar in Pakistan ran on a simple, generous deal: every unit you exported to the grid offset a unit you imported later, at the same price. That 1:1 unit banking is now gone. Under **NEPRA's Prosumer Regulations 2026** — notified on 9 February 2026 — Pakistan has shifted from *net metering* to *net billing*, and the change rewrites the economics of every solar system in the country.

The headline problem is brutal in its simplicity. Your surplus solar is now **cash-settled monthly at roughly Rs 11–13 per unit** (the National Average Power Purchase Price), while you still buy grid electricity back at **Rs 22–27 per unit or more**. Any unit you export instead of using yourself loses roughly half its value the instant it crosses your meter.

This guide explains exactly what changed and, more importantly, how to redesign your solar system so you keep that value at home.

What NEPRA's Prosumer Regulations 2026 Actually Changed

The old **net metering** regime (SRO-based, in place since 2015) treated the grid like a free battery. You banked summer surplus and carried it forward against winter or night-time imports, unit for unit.

**Net billing** breaks that link. The key changes:

  • **No more 1:1 unit banking or carry-forward.** Exports and imports are now two separate transactions at two different prices.
  • **Surplus is bought at the NAPPP** — about Rs 11–13 per unit for the national average, with new-consumer buyback rates reported as low as Rs 8.13 per unit in some notifications, down from the ~Rs 25 you effectively earned before.
  • **You still import at the full consumer tariff** — commonly Rs 22–27 per unit on protected and mid slabs, and higher on peak/unprotected slabs once taxes and surcharges stack up.
  • **Contract term cut from 7 years to 5 years.**
  • **Existing consumers are protected** — those with live agreements keep their old terms until the contract expires, after which the DISCO may shift them to net billing.

The grid is no longer your battery. It is now a wholesale buyer that pays you half of what it charges you. Design accordingly.

According to the NEPRA notification reported by The Express Tribune, the regulator's stated aim is to rebalance costs that were shifting onto non-solar consumers. Whatever the policy logic, the practical takeaway for you is the same: **self-consumption is now king.**

Why the Old "Oversize It" Advice Now Costs You Money

Under net metering, the smart move was to oversize — fit as many kilowatts as your roof and budget allowed, bank the surplus, and zero out your bill. That maths has flipped.

Consider a household that exports 300 units of midday surplus in a month:

| Scenario | Value of 300 exported units | Effective loss vs. self-use | |---|---|---| | Old net metering (offset at ~Rs 25) | ~Rs 7,500 | Rs 0 (full retail value) | | New net billing (sold at ~Rs 12) | ~Rs 3,600 | ~Rs 3,900 lost per month |

That's roughly **Rs 46,000 a year** of value evaporating from a single oversized system — simply because the panels produce when nobody is home to use it. The fix is not fewer panels; it's a system designed so production and consumption line up.

How to Redesign Your Solar System for Net Billing

The new goal is **self-consumption ratio** — the share of your generation you use on-site rather than exporting. Push that number up and net billing barely touches you. Here's how.

### 1. Right-size the array to your daytime load, not your total bill

Size the panels closer to what your home or business actually consumes during sunlight hours. A big commercial user that runs machinery all day can still justify a large array. A home that's empty from 9 to 5 should not chase a bill of zero by dumping units to the grid at Rs 12.

### 2. Add a battery and go hybrid

A **hybrid inverter plus lithium (LiFePO₄) battery** is now the single highest-value upgrade. Store midday surplus and discharge it in the evening peak — when you'd otherwise import at Rs 22–27. Every stored unit you self-consume is worth the *retail* price you avoid, not the wholesale price you'd have been paid. With battery pack prices falling through 2026, payback periods have tightened considerably. See our solar battery buying guide for Pakistan for current chemistry and sizing advice.

### 3. Shift heavy loads into daylight hours

Behaviour is free capacity. Run these while the sun is up:

  • Washing machines and dishwashers on daytime timers
  • Water pumps and motors for tanks and irrigation
  • EV and e-bike charging at midday
  • Pre-cooling the house (or a cold store) before evening peak

### 4. Use smart controls to soak up surplus

Timers, smart plugs, and inverter-linked load controllers can automatically divert excess solar to an inverter AC, a water heater, or a pool pump instead of exporting it. Some hybrid inverters do this natively with "zero-export" or "self-use priority" modes.

### 5. Model the payback before you sign

Ask your installer for a projection based on your real hourly load profile — not a generic "zero bill" promise. A well-designed net-billing system in 2026 still delivers strong returns, but only when it's built around *your* consumption curve. Our net metering vs net billing explainer walks through the numbers.

Should Existing Net-Metering Consumers Panic?

No — but plan ahead. If you have a live net-metering agreement, you keep 1:1 banking until your contract expires. Use that runway to:

  • **Add battery storage now**, so when your DISCO migrates you to net billing you're already optimised for self-consumption.
  • **Avoid expanding** an old system in a way that only makes sense under banking rules.
  • **Track your export ratio** monthly so you know exactly how exposed you'll be at renewal.

New applicants should simply design for net billing from day one. The technology to do that — hybrid inverters and affordable lithium storage — is mature and widely available across Pakistan in 2026.

Frequently Asked Questions

**Is solar still worth it in Pakistan after net billing in 2026?** Yes. With grid tariffs at Rs 22–27+ per unit and rising, every unit you generate and *self-consume* still saves you the full retail price. Net billing only reduces the value of *exported* surplus, so a system sized around your daytime load — ideally with a battery — remains one of the best investments a Pakistani household or business can make.

**How much will DISCOs pay for my surplus units now?** Surplus is cash-settled monthly at around the National Average Power Purchase Price — roughly Rs 11–13 per unit — with some new-consumer buyback notifications as low as Rs 8.13 per unit. This is far below the Rs 22–27 you pay to import, which is why exporting is now the least valuable thing your panels can do. Always confirm the exact figure with your own DISCO.

**Do I need a battery under the new net billing rules?** You don't strictly need one, but a battery is now the highest-return add-on. It lets you store cheap midday solar and use it during the evening peak instead of importing at full tariff — capturing the retail-price value that net billing otherwise strips out of your surplus.

**Will existing net-metering agreements be cancelled?** No. Consumers with active agreements keep their existing 1:1 terms until the contract ends. After expiry, the DISCO may move you onto net billing, so it's wise to prepare for self-consumption before then.

The Bottom Line

Net billing hasn't killed rooftop solar in Pakistan — it has changed the winning strategy. The old game was to generate as much as possible and bank it. The new game is to **use as much of your own generation as possible**, storing the rest in a battery rather than selling it to the grid for half price.

Design your system around your consumption, add storage, and shift your loads into the sun. Do that, and NEPRA's 2026 rules become a footnote rather than a setback.
