Solar vs Grid Electricity: Cost Comparison for Pakistan (2026)

Why This Comparison Matters Now

Pakistani electricity tariff rates have increased dramatically over the past three years, while solar system costs have fallen. The economics of rooftop solar that barely made sense in 2020 now look compelling for many households — but the decision depends heavily on your consumption level, bill amount, and how much of your roof is usable.

This comparison uses illustrative ranges rather than specific per-unit figures because NEPRA rates change quarterly. The ratios and logic hold; verify the current published tariffs at nepra.org.pk before finalizing any investment decision.

What You Pay for Grid Electricity

For unprotected domestic consumers (which most households over 200 units/month are), the effective per-unit cost including all surcharges and taxes typically lands between Rs. 25–45 per unit depending on consumption slab and the month's FPA. Heavier consumers in higher slabs pay more per unit than light consumers.

A household using 400 units/month might pay Rs. 12,000–18,000 per month in summer. One using 600 units/month might pay Rs. 22,000–30,000. These are the numbers that make solar worth evaluating seriously.

What Solar Costs to Install

As of mid-2026, typical installed solar system costs in Pakistan (panels + hybrid inverter + wiring, without batteries) range from Rs. 80,000–100,000 per kilowatt-peak (kWp) installed. A 5 kWp system runs approximately Rs. 400,000–500,000. Lithium battery bank (5 kWh) adds Rs. 300,000–600,000.

Prices vary significantly by brand, installer, and city. Chinese-brand monocrystalline panels with a Tier 2 inverter are at the lower end; Tier 1 panels (Longi, JinKo, Canadian Solar) with European inverters (Solis, GoodWe) are at the higher end. Both tiers perform adequately in Pakistani conditions.

Annual Savings: What to Expect

A 5 kWp system in Lahore generates approximately 7,500–8,500 kWh per year (1,500–1,700 kWh per kWp/year). If your grid tariff effective rate is Rs. 30/unit, that's Rs. 225,000–255,000 in annual savings — if all production directly offsets grid import.

With net metering, surplus daytime production is exported and credited against nighttime consumption. Without net metering (off-grid or pre-meter-approval), value is realized only through self-consumption — appliances must run when the sun shines, otherwise the production is wasted (or stored in batteries at additional cost).

Payback Period Calculation

Payback period = Total system cost ÷ Annual savings. For a Rs. 450,000 system (5 kWp without batteries) saving Rs. 240,000/year: payback is 1.9 years. This is an unusually short payback for any capital investment.

Adding a Rs. 400,000 battery bank (5 kWh LFP) increases total cost to Rs. 850,000 and the battery contributes about Rs. 50,000–80,000 in additional value (load-shedding avoidance, avoiding peak-rate purchases in the evening). At Rs. 300,000 total annual savings: payback 2.8 years.

These are favorable conditions. For lighter users (200 units/month, Rs. 6,000 bills), solar payback can extend to 6–8 years — still reasonable over a 10-year panel warranty, but less compelling.

When Solar Clearly Makes Sense

Solar is a straightforward investment when: your monthly bill is Rs. 10,000 or more, you have adequate south-facing roof space with minimal shading, you plan to stay in the property for 5+ years, and your DISCO processes net metering applications (all 11 DISCOs do).

The higher your bill, the faster the payback. A household paying Rs. 25,000/month has approximately a 1.5–2 year payback on an appropriately sized system. The math is less compelling at Rs. 4,000/month, but load-shedding avoidance may still justify a partial system.

When to Be Cautious

Heavily shaded roofs significantly reduce output — one shaded panel in a series string can drag down the entire string's production. If trees, water tanks, or neighboring buildings shade more than 15% of your proposed array area during peak hours, the economics worsen substantially. A microinverter or DC-optimized system mitigates shading impact but costs more.

Tenant households or those uncertain about staying long-term face a challenge: the payback period may exceed the expected tenancy. Solar panels are attached to the structure and typically do not move with the tenant. Some landlords are willing to install systems and recoup cost via slightly higher rent — negotiate this explicitly before installation.

Net metering tariff changes are a regulatory risk. If NEPRA revises export credit rates downward — which has happened in some markets — the economics change for grid-connected systems. Off-grid or battery-heavy systems are insulated from this risk but cost more upfront.

Summary: Solar vs Grid at a Glance

Grid electricity in Pakistan is: immediately available with no upfront cost, but expensive at Rs. 25–45/unit for unprotected consumers, subject to load shedding, and affected by quarterly tariff increases that have been persistently upward.

Rooftop solar is: Rs. 80,000–100,000/kWp upfront, generates electricity at an effective cost of Rs. 5–10/unit over its 20–25 year lifespan (amortized system cost), available 24/7 when paired with batteries, and immune to future tariff increases on self-consumed production. For households spending Rs. 10,000+ per month on electricity, solar is among the highest-returning investments available in Pakistan today.
