If your latest bill made you do a double take, you are not imagining it. In 2026, electricity has crossed **Rs 60 per unit** for most unprotected households across MEPCO, LESCO, K-Electric and other DISCO zones once every surcharge is stacked on top of the base rate. That is roughly **155% higher than 2021**, when the same household paid in the low-to-mid Rs 20s per unit.

This is exactly why solar has stopped being a "nice-to-have" and become a straight financial decision. Even after NEPRA weakened the rules for new rooftop systems in 2026, **daytime solar self-consumption** still cuts a real monthly bill dramatically. Let's break down the numbers honestly.

Why electricity crossed Rs 60 per unit

The headline base tariff looks deceptively low. NEPRA's approved residential slabs sit around **Rs 22 to Rs 47 per unit**. But that is never what you actually pay. Layered on top are:

  • **Fuel Price Adjustment (FPA)** — Rs +1.50 to Rs +6.80 per unit in recent months
  • **Quarterly Tariff Adjustment (QTA)**
  • **Financing / Neelum-Jhelum surcharge**
  • **Fixed charges** based on sanctioned load
  • **Electricity Duty** (provincial)
  • **General Sales Tax at 17%**
  • **PTV fee** and other line items

Together these add roughly 60–90% on top of the base rate. That is how a mid-slab household lands at an **effective Rs 60–75 per unit** — even though no single slab on the schedule says "60."

The rate printed on the tariff schedule is not the rate you pay. The all-in cost per unit — after FPA, surcharges, duty and 17% GST — is what actually hits your account.

What a real monthly bill looks like in 2026

Consider a typical unprotected family home in Lahore or Karachi running two ACs in summer and consuming **800 units** a month. Here is a realistic breakdown:

| Bill component | Approx. amount (PKR) | |---|---| | Energy charges (slab-based, ~800 units) | 34,500 | | Fuel Price Adjustment (FPA) | 3,200 | | Quarterly / financing surcharges | 2,600 | | Fixed & meter charges | 1,000 | | Electricity Duty | 700 | | GST @ 17% | 7,100 | | PTV fee | 35 | | **Total monthly bill** | **~49,000** |

That works out to an effective **~Rs 61 per unit**. For a small business or a larger home hitting 1,200–1,500 units, the monthly bill sails past **Rs 80,000–100,000**. These are not extreme cases in 2026 — they are the new normal.

The 2026 rule change: net metering became net billing

Here is the part that worries buyers. In February 2026, NEPRA notified the **Prosumer Regulations 2026**, ending classic **net metering** for new solar consumers and moving them to a **net-billing** model.

The difference matters:

  • **Old net metering:** every unit you exported was credited against a unit you imported, effectively at the full retail rate (around Rs 25+ per unit).
  • **New net billing (2026):** surplus units you send to the grid are bought back at a much lower rate — reported between roughly **Rs 8 and Rs 11 per unit** for new consumers, down from the earlier ~Rs 27.
  • **Existing consumers** stay on their prior arrangement (around Rs 25.3 per unit) for the remainder of their contract.
  • **New contracts** run for **5 years** instead of 7.

At first glance this looks like bad news. In reality, it just changes the *smart* way to use solar — and the math still lands firmly in your favour.

Why daytime self-consumption still wins big

The key insight for 2026 is the gap between two numbers:

  • **Retail rate you avoid** by using your own solar power: **~Rs 60 per unit**
  • **Buyback rate you get** for exporting surplus: **~Rs 10 per unit**

Every unit your panels produce that you **use immediately** — running the AC, the fridge, the water pump, the office at 1 PM — saves you the full **Rs 60**. Every unit you *export* only earns Rs 10. So the whole game in 2026 is to **consume your solar during daylight hours** rather than push it to the grid.

The good news: your biggest loads are already in the daytime. Air conditioning, water pumping, ironing, and commercial operations all peak while the sun is up. That alignment is what makes solar self-consumption so powerful right now.

Take a **5kW system** in Punjab or Sindh. It generates roughly **20–25 units per day**, or about **600–750 units a month** across the year. If a household self-consumes most of that at Rs 60 per unit, the monthly saving is around **Rs 36,000 to Rs 45,000** — turning that Rs 49,000 bill into something closer to Rs 10,000–14,000.

The numbers: payback is still 2–3 years

A grid-tied **5kW system** in 2026 costs roughly **PKR 900,000 to 1,150,000** installed, depending on panel and inverter brands. Against annual savings of **Rs 430,000–520,000** from avoided daytime units, the payback period lands at about **2 to 3 years** — after which the power is essentially free for the 20–25 year panel life.

Here is a simple comparison of the three strategies in the net-billing era:

| Strategy | Best for | 2026 verdict | |---|---|---| | Oversized on-grid (export heavy) | Old net metering | Weak — surplus only earns ~Rs 10 | | Right-sized on-grid (self-consume) | Daytime-heavy homes/offices | Strong — avoids Rs 60/unit | | Hybrid with battery | Evening peak users | Best — stores cheap solar for night |

Because the buyback rate is now so low, **oversizing purely to sell to the grid no longer pays**. Instead, size the system to your daytime load, and if your usage is evening-heavy, add a **lithium-ion battery** so you store cheap solar for the expensive night hours. Our team walks through this in the hybrid solar system guide for Pakistan, and you can compare current hardware costs on our solar panel price page.

Practical tips to maximise self-consumption

From dozens of installs across Punjab and Sindh, these habits move the needle the most:

  • **Shift heavy loads to daylight** — run the washing machine, iron and water pump between 10 AM and 4 PM.
  • **Right-size, don't oversize** — match panel capacity to your daytime demand, not your total units.
  • **Set AC thermostats to 26°C** during solar hours to stretch free cooling.
  • **Consider a small battery** only if your evening usage is genuinely high — it changes the payback math.
  • **Read your own bill** — check the effective per-unit cost, not just the slab rate, so you know your true baseline.

Frequently Asked Questions

**Is solar still worth it in Pakistan after the 2026 net-billing change?** Yes — arguably more than ever. The buyback rate dropped, but the retail rate you avoid is around Rs 60 per unit. As long as you use your solar power during the day, you save the full retail price, and payback stays at roughly 2–3 years for a right-sized system.

**How much can a 5kW solar system save me each month?** A 5kW system generates about 600–750 units monthly. Self-consumed at ~Rs 60 per unit, that is roughly Rs 36,000–45,000 in monthly savings, which can cut a Rs 49,000 bill down to around Rs 10,000–14,000.

**What is the difference between net metering and net billing?** Under net metering, exported units were credited near the full retail rate. Under 2026 net billing, exported surplus is bought back at a much lower rate (about Rs 8–11 per unit), so the smart strategy shifts from exporting to consuming your own solar during the day.

**Should I add a battery to my solar system in 2026?** Only if your electricity use is heavy in the evening. A lithium-ion battery lets you store cheap daytime solar for expensive night hours. For daytime-dominant homes and offices, a well-sized on-grid system without a battery already delivers excellent returns.

The bottom line

With electricity crossing **Rs 60 per unit** in 2026 and bills routinely topping Rs 49,000 for an average home, waiting for tariffs to fall is not a strategy. Even under the weaker net-billing rules, **daytime solar self-consumption** slashes your bill fast and pays for itself in 2–3 years. Size your system to your daytime load, use the power as you make it, and let the grid become your backup — not your burden.
