Something dramatic just happened in Pakistan's energy market, and if you own solar panels or plan to buy them, it changes the math completely. Between January 2024 and June 2026, monthly lithium battery imports surged roughly **1,640%**, climbing from about 42 MWh to a record 652 MWh. Over that same window Pakistan pulled in more than 6 GWh of lithium-ion cells worth around **$454.7 million, close to Rs126 billion**.

This is not a coincidence. It lines up almost exactly with NEPRA scrapping the old net metering deal. The clear message from thousands of Pakistani households and businesses is simple: stop exporting cheap power to the grid, and start storing it for yourself.

What Actually Changed With Net Billing

Until early 2026, solar owners enjoyed **net metering**. Every unit you exported to the grid offset a unit you imported, effectively at retail value. It was a one-for-one swap, and payback periods were short.

On **9 February 2026**, NEPRA moved new applicants to a **net billing** model under the Prosumer Regulations 2026. Now imports and exports are priced separately, and they are nowhere near equal:

  • **Exported units** are bought back at roughly **Rs11 per unit** for new consumers (some tariff notifications reference figures as low as Rs8.13).
  • **Imported units** still cost you around **Rs50 to Rs55 per unit** once taxes and surcharges stack up.
  • **Existing net metering customers** who signed before the cutoff are grandfathered and keep selling at the older **Rs25.32 per unit** rate.

When you export a unit under net billing you earn about Rs11, but you pay roughly Rs55 to buy that same unit back after sunset. That is a five-to-one loss on every kilowatt-hour you give away.

That gap is the entire story. Sending surplus solar to the grid now means handing over electricity worth Rs55 in exchange for Rs11. A battery lets you keep it.

Why Storage Beats Exporting: The New Math

Picture a typical Lahore or Karachi home with a 10 kW solar system that produces around 8 to 10 surplus units on a sunny day after midday loads are covered.

**Under the old net metering:** those 10 exported units earned you about Rs250 to Rs253 in credit, and you used them freely at night.

**Under net billing today:** those same 10 exported units earn only about **Rs110**. But if you store them in a battery and use them at night instead of buying from the grid, you avoid paying roughly **Rs550**.

The difference between exporting (Rs110) and self-consuming through storage (Rs550 avoided) is around **Rs440 every single day**, or roughly **Rs13,000 per month** for that one household. That is the real return a battery now delivers, and it explains the import boom perfectly.

Here is the comparison at a glance:

| Scenario | Value per exported/stored unit | Daily outcome (10 units) | Monthly impact | |---|---|---|---| | Old net metering (export) | ~Rs25.32 | ~Rs253 credit | ~Rs7,600 | | New net billing (export) | ~Rs11 | ~Rs110 credit | ~Rs3,300 | | New net billing + battery (self-use) | ~Rs55 avoided | ~Rs550 saved | ~Rs16,500 |

Storage does not just beat exporting under the new rules. It roughly triples the value you get from every surplus unit compared to selling it back.

What a Battery Actually Costs in 2026

The good news is that lithium prices have fallen sharply as import volumes scaled up. In August 2026, the market looks like this:

  • **LiFePO4 (lithium iron phosphate)** is the standard choice for Pakistani homes, offering **8,000-plus charge cycles** and a **15 to 20 year** service life.
  • A **5 kWh (51.2V 100Ah)** unit typically runs **Rs185,000 to Rs310,000** depending on brand, BMS quality, and warranty.
  • Blended pricing sits around **Rs40,000 to Rs55,000 per usable kWh**.
  • Established brands like **Pylontech, Dyness, Knox, and BYD** carry longer warranties and better battery management systems, which matter in Pakistan's heat.

For the 10 kW household in our example saving about Rs13,000 to Rs16,000 a month, a 10 kWh battery pack costing around Rs450,000 to Rs550,000 can pay for itself in roughly **3 years**, then deliver a decade or more of essentially free evening power. That is a stronger payback than the panels themselves offered under the old export scheme.

How to Size Storage the Smart Way

You do not need to store every unit. The goal is to cover your evening and overnight load, the hours when the grid is most expensive and solar production is zero.

1. **Check your night consumption.** Add up fans, lights, fridge, and any AC that runs after sunset. Most homes need 5 to 12 kWh of overnight backup. 2. **Match the battery to that number,** not to your total daily generation. Oversizing wastes capital. 3. **Insist on a hybrid inverter** that supports lithium and can prioritise self-consumption over export. 4. **Choose LiFePO4 over lead-acid.** The upfront price is higher, but cost-per-cycle is far lower over 15 years. 5. **Keep a small export allowance.** A tiny grid feed still trims your bill and keeps your connection compliant.

Is Solar Still Worth It Under Net Billing?

Absolutely, and arguably more than ever. Solar plus storage now targets **self-consumption**, which is protected from both rising grid tariffs and shrinking buyback rates. You are no longer betting on a government export price that can be cut again. You are simply refusing to buy Rs55 electricity when you already generated it for free.

The 1,640% import surge is not hype. It is hundreds of thousands of Pakistani households and businesses running the same numbers and reaching the same conclusion: in the net billing era, the battery is where the savings live.

Frequently Asked Questions

**Why did lithium battery imports jump 1,640% in Pakistan?** The surge, from about 42 MWh monthly to 652 MWh and worth roughly Rs126 billion in total, tracks directly with NEPRA ending net metering. Once export credits fell to around Rs11 per unit, storing solar power became far more valuable than selling it, so demand for batteries exploded.

**How much is the solar export rate under net billing in 2026?** New consumers who applied after 9 February 2026 receive roughly Rs11 per exported unit (some notifications cite Rs8.13). Existing net metering customers are grandfathered at the older Rs25.32 per unit rate, while grid imports still cost around Rs50 to Rs55 per unit.

**Should I add a battery to my existing solar system?** If you are a new solar owner under net billing, yes. Self-consuming a unit saves you about Rs55, while exporting it earns only about Rs11. A LiFePO4 battery that covers your evening load can pay back in around 3 years and last 15 to 20 years.

**What size solar battery do most Pakistani homes need?** Most households need 5 to 12 kWh to cover overnight loads like fans, fridge, lights, and evening AC. Size the battery to your night-time consumption rather than your total daily generation to avoid overspending.

The Bottom Line

Net billing rewrote the rules, and the market has already voted with Rs126 billion. Exporting solar for Rs11 while buying it back for Rs55 no longer makes sense. Pairing your panels with a LiFePO4 battery keeps that value at home, shields you from future tariff cuts, and pays for itself faster than ever.
