Something remarkable happened to Pakistan's power system while many households were still debating whether solar was "worth it." According to the **Pakistan Electricity Review 2026** and analysis from the Pakistan Solar Association, distributed solar in Pakistan now supplies close to **27% of all the electricity the country generates** — and it barely shows up in official grid data.

If you are a homeowner or small business still on the fence, that single number changes the conversation. Solar is no longer an early-adopter gamble. It has quietly become mainstream infrastructure, and the economics for the people who wait are getting harder, not easier.

The numbers behind Pakistan's solar boom

The headline figures from the 2026 review are genuinely staggering for a country that struggled with load-shedding barely a few years ago:

• **~51 GW of solar capacity** is now estimated to be operational as of early 2026 — nearly equal to the entire installed capacity of the national grid, according to Renewables First.
• Behind-the-meter solar generated roughly **51 TWh** of electricity that never appears in grid statistics, lifting Pakistan's true generation from about 135 TWh to **186 TWh**.
• On the LESCO network, **midday grid demand has collapsed to just 765 MW in 2026**, down from a flat ~2.2 GW in 2024. Rooftops are now doing the work the grid used to do at noon.

This is what "solar going mainstream" actually looks like. Module imports have flooded in — Pakistan imported enough panels to add tens of gigawatts — because ordinary families did the maths on a diesel-and-grid future and voted with their wallets.

What it means if you are still on the grid

Here is the uncomfortable part. As millions shift to self-generation, the fixed costs of the grid — transmission lines, capacity payments, fuel — get spread across fewer paying units. That puts steady upward pressure on the per-unit tariff for everyone who has **not** gone solar.

In plain terms: the longer you stay a full grid customer, the more you subsidise a system you use less and less efficiently. Peak retail tariffs for protected and unprotected residential slabs have kept climbing, while your neighbour with a 10kW rooftop covers most daytime load for free.

Daytime is exactly where the collapse is happening. If your home or shop runs air-conditioning, refrigeration, fans or machinery between 9am and 5pm, that is the load solar erases most cheaply. For a deeper walkthrough, see our guide to sizing a home solar system.

The 2026 rule change you must understand: net billing

Timing now matters more than ever because of a major regulatory shift. In February 2026, NEPRA replaced the old one-to-one **net metering** scheme with a **net billing** model under the new Prosumer Regulations. This is the single biggest reason not to keep waiting.

Under the old system, every unit you exported cancelled a unit you imported — a clean 1:1 swap. Under net billing:

• You pay the **full retail rate** for every unit you import from the grid.
• Your exported surplus is credited separately at a much lower **buyback rate**.
• New connections sign a **five-year contract**.

The financial gap is large. Consumers who locked in before the cut-off keep selling at around **Rs 25.32 per unit**, while new applicants after **9 February 2026** receive a buyback of roughly **Rs 8.13 per unit** — a reduction of over Rs 17. You can read NEPRA's own framework on the regulator's official site.

The practical takeaway: the value now lies in **self-consumption**, not in exporting a big surplus. A right-sized system that you actually use during the day beats an oversized one dumping cheap units to the grid.

Old net metering vs new net billing (2026)

| Factor | Net Metering (pre-Feb 2026) | Net Billing (new, 2026) | |---|---|---| | Export treatment | 1 unit exported = 1 unit imported | Import at full retail; export credited separately | | Buyback rate | ~Rs 25.32/unit (grandfathered) | ~Rs 8.13/unit for new consumers | | Contract term | Legacy terms until expiry | 5-year prosumer contract | | Best strategy | Oversize, bank surplus | Right-size, maximise self-use | | Who qualifies now | Applications before 8 Feb 2026 | All new applications |

What a system actually costs in 2026

The good news is that falling panel prices have partly offset the softer buyback rate. As of 2026, a typical **on-grid 10kW system in Lahore, Faisalabad or Karachi costs roughly PKR 850,000 to PKR 1,200,000**, including inverter, mounting, a bidirectional (green) meter and net-metering approval. A system that size produces around **52–55 units per day** in most Pakistani cities.

A realistic worked example for a 1-kanal home:

• **System size:** 10kW on-grid
• **Approx. cost:** PKR 1,000,000
• **Daily output:** ~53 units
• **Monthly bill offset:** PKR 60,000–80,000 for a heavy summer user

With self-consumption prioritised under net billing, many households still see **payback in roughly 3 to 4.5 years**, then a decade or more of near-free daytime power on 25-year panels. Adding a small lithium battery to shift solar into the expensive evening ramp — where LESCO now sees a 1.1 GW surge over four hours — improves the case further.

First-hand tip from our installs

From systems we have commissioned across Punjab, the most common regret is **buying too small to save money upfront**, then wanting to expand after the first summer bill. Under a five-year net-billing contract, resizing mid-term is a hassle. Size for your realistic 3-year load, insist on a Tier-1 panel and a reputable string or hybrid inverter, and get the net-billing paperwork filed correctly the first time. Cheap inverters are where budget systems fail in Pakistan's heat.

Frequently Asked Questions

**Is distributed solar really supplying 27% of Pakistan's electricity?** Yes — the Pakistan Solar Association's analysis, cited in the Electricity Review 2026, estimates behind-the-meter solar generated around 51 TWh in FY2025, roughly 27% of true national generation. Most of it is invisible in grid data because it is consumed on-site.

**Does the new net billing rule make solar not worth it in 2026?** No. It lowers the reward for exporting surplus, but self-consumption savings are unchanged. Because you avoid full retail tariffs on daytime units, a right-sized system in 2026 still typically pays back in about 3–4.5 years.

**Should I rush to install before rates change again?** The most favourable net-metering terms already closed in February 2026. New systems fall under net billing regardless, so there is no old rate left to "beat" — but every month you wait is a month of full-price grid bills you could have offset.

**How much does a home solar system cost in Pakistan right now?** A quality on-grid 10kW system runs about PKR 850,000–1,200,000 installed, including the green meter and approvals. Smaller 5kW setups start near PKR 550,000, while hybrid systems with batteries cost more.

The bottom line

The Electricity Review 2026 confirms what rooftops across Lahore, Karachi and Faisalabad already show: distributed solar in Pakistan has crossed from niche to mainstream. Midday grid demand is collapsing, 51 GW is installed, and the households still fully on the grid are increasingly the ones footing rising fixed costs.

Net billing changed the rules, not the fundamentals. Solar still slashes your daytime bills, still pays back in a few years, and still protects you from the next tariff hike. If you have been waiting for a sign that solar has "arrived," a quarter of the national grid just gave you one.
