Solar in Pakistan in 2026 is no longer a green-energy decision — it is a financial one. With unprotected domestic tariffs above Rs 50 per unit at the top slab (energy + FPA + QTA + GST + DSC stacked), most middle and upper-middle-class households recover the entire installed cost of a 10 kW system in under four years. After that, electricity is essentially free for the next 21 years of panel life.
This guide gives you honest, slab-by-slab payback math for 5 kW, 10 kW and 15 kW homes in Pakistan, compares cash purchase vs bank financing (PSB Solar Finance, Meezan Bank, JS Bank), and shows the realistic monthly bill savings after the 2026 NEPRA net-billing rate change.
What changed in 2026 (and what didn’t)
Three structural shifts hit solar economics in Pakistan this year:
- Net-billing replaced net-metering for new applicants. Exported units are now compensated at Rs 11 (NEPRA average buyback) instead of the retail tariff. Self-consumed units still save at full retail value.
- Panel and inverter prices fell ~15–20% year-on-year. Tier-1 585W panels are Rs 19,000–22,000 in May 2026 vs Rs 24,000 a year ago.
- Bank solar financing rates dropped. SBP-mandated solar refinance brought rates to KIBOR + 2–4% (effective ~14–16% in 2026) on 5- to 7-year terms.
Net result: cash payback is roughly unchanged from 2025, financed payback is shorter by 6–9 months, and the IRR is actually higher because installed cost fell faster than the buyback rate cut.
2026 NEPRA tariff snapshot (unprotected domestic)
All-in cost per unit (energy + FPA + QTA + ED + Neelum-Jhelum + DSC + 17% GST) for a typical LESCO / IESCO / MEPCO unprotected domestic consumer, May 2026:
| Slab (units/month) | NEPRA energy rate | All-in cost/unit * |
|---|---|---|
| 1–100 | Rs 13.48 | ~Rs 22 |
| 101–200 | Rs 18.95 | ~Rs 29 |
| 201–300 | Rs 22.14 | ~Rs 34 |
| 301–400 | Rs 28.07 | ~Rs 42 |
| 401–500 | Rs 33.92 | ~Rs 49 |
| 501–600 | Rs 36.18 | ~Rs 52 |
| 601–700 | Rs 39.45 | ~Rs 56 |
| 700+ | Rs 42.72 | ~Rs 60 |
* Includes FPA Rs ~3.5/unit, QTA Rs ~1.5/unit, DSC Rs 3.23/unit, surcharges and 17% GST. Actuals vary monthly with NEPRA notifications.
K-Electric Karachi tariffs are roughly Rs 2–4 per unit higher in equivalent slabs once TAC is added.
System cost breakdown (May 2026, installed)
Real Lahore and Karachi installed prices from Capital IT and competitor quotations — turnkey, including mounting, cabling, AC/DC protection, online monitoring and net-metering paperwork:
| System | On-grid | Hybrid + battery | Generates / month |
|---|---|---|---|
| 5 kW | Rs 6.5–7.5 lakh | Rs 9–11 lakh (10 kWh LFP) | ~700 units |
| 10 kW | Rs 11–13 lakh | Rs 16–19 lakh (15 kWh LFP) | ~1,400 units |
| 15 kW | Rs 16–19 lakh | Rs 23–28 lakh (20 kWh LFP) | ~2,100 units |
Generation assumes an unshaded south-facing Lahore roof at 4.7 peak sun hours, 78% performance ratio. Karachi is ~5% higher, Islamabad ~5% lower, Quetta and Bahawalpur ~8–10% higher.
5 kW home: payback math by bill size
A 5 kW on-grid system generates roughly 700 units a month. The right system size for a household using 500–800 units. Installed cash cost: Rs 7 lakh.
- If your current bill is Rs 18,000/month (500 units): system covers your entire usage, monthly savings ~Rs 18,000, payback ~3.2 years.
- If your current bill is Rs 28,000/month (700 units): savings ~Rs 25,000, payback ~2.3 years.
- If your current bill is Rs 12,000/month (350 units): system overgenerates; export at Rs 11/unit; payback ~4.0 years. Consider a 3 kW system instead.
Add a 10 kWh LFP battery (Rs 2.8 lakh extra) for backup during load shedding — payback extends by ~9 months but you escape both bill and outage.
10 kW home: the sweet spot for Lahore DHA, Bahria Town, Defence Karachi
A 10 kW hybrid system is the most-installed configuration in Pakistan in 2026. Generates ~1,400 units a month, covers a 5-marla to 1-kanal household with AC and electric water heating. Installed cost with 15 kWh LFP battery: Rs 17.5 lakh average.
| Current bill | Monthly saving | Annual saving | Cash payback | Financed payback * |
|---|---|---|---|---|
| Rs 30,000 | Rs 28,500 | Rs 342,000 | 5.1 yrs | 5.5 yrs |
| Rs 45,000 | Rs 42,000 | Rs 504,000 | 3.5 yrs | 3.8 yrs |
| Rs 60,000 | Rs 55,000 | Rs 660,000 | 2.7 yrs | 3.0 yrs |
| Rs 80,000 | Rs 70,000 | Rs 840,000 | 2.1 yrs | 2.4 yrs |
* Financed at PSB Solar Finance, 7-year term, KIBOR + 3% (~15.5% effective).

15 kW home: large kanals, farmhouses, commercial-residential mixed use
Common for 1-kanal-plus houses in Lahore Cantt, Islamabad F-7/F-8, DHA Karachi Phase 8, and farmhouses on Bedian Road or Bahria Orchard. Generates ~2,100 units/month. Installed cost with 20 kWh LFP: Rs 26 lakh.
- Rs 70,000 current bill: save ~Rs 65,000/month — payback 3.4 years cash.
- Rs 100,000 current bill: save ~Rs 88,000/month — payback 2.5 years cash.
- Rs 140,000 current bill (commercial-domestic mixed): save ~Rs 115,000/month — payback 1.9 years cash.
Cash vs financed: which is actually better?
Three options for a Pakistani household buying solar in 2026:
Option 1: Pay cash
- Lowest total cost. Fastest IRR.
- Ties up Rs 11–26 lakh in an illiquid asset.
- Best for households with idle savings earning <10% in bank deposits.
Option 2: PSB Solar Finance (State Bank refinance scheme)
- Up to Rs 25 lakh; 5-year term standard, 7-year for residential.
- Rate: KIBOR (currently ~12.5%) + 3% spread = ~15.5% effective.
- EMI on Rs 17 lakh, 7 years, 15.5%: roughly Rs 33,800/month.
- If bill savings are Rs 42,000/month, you are net positive Rs 8,000/month from month one.
Option 3: Bank solar products (Meezan Aasaan Solar, JS Bank Solar, HBL, BankIslami)
- Meezan Aasaan Solar — Diminishing Musharakah, Shariah-compliant, 5- to 7-year term, similar effective rate to PSB.
- JS Bank Solar — up to 10 years on residential, slightly higher rate (KIBOR + 4%).
- HBL Asaan Solar — quick processing, salaried-only, up to Rs 15 lakh.
- Most banks finance only the EPC contractor’s invoice, not consumer self-procurement.
The cash-flow truth nobody tells you
For a typical Lahore household with a Rs 45,000/month unprotected domestic bill, here is the actual cash flow of a financed 10 kW hybrid system in year 1:
- Monthly bill before solar: Rs 45,000
- Monthly bill after solar (small balance import): Rs 3,500
- Monthly bank EMI (PSB, 7 yr, Rs 17 lakh): Rs 33,800
- Net monthly outflow: Rs 37,300 vs Rs 45,000 before — saving Rs 7,700/month from day 1.
After year 7, EMI ends — entire Rs 41,500 monthly saving accrues for the remaining 18 years of panel life. Total 25-year financial benefit: Rs 95–120 lakh, vs Rs 17 lakh financed cost. That is the IRR story.
Hidden costs people forget
Honest accounting requires deducting these from gross savings:
- AMC (Annual Maintenance Contract) — Rs 15,000–25,000/year typical for cleaning + inspection.
- Inverter replacement at year 10–12 — Rs 1.5–2.5 lakh for a 10 kW unit at 2036 prices.
- Battery replacement at year 10–12 — Rs 2.5–4 lakh for LFP at 2036 prices.
- Panel degradation — ~0.4%/year for N-type TOPCon, so year-25 output is ~90% of year-1.
- Net-metering application fee — Rs 5,000–15,000 one-time, plus bidirectional meter cost (~Rs 25,000–40,000).
Even with all of these, the 25-year IRR for a cash purchase in 2026 is typically 22–28% — far above any safe-instrument return available to Pakistani households.
Tariff slab traps to watch
A subtle issue: if your pre-solar bill is exactly at a slab boundary (say 500 units, top of Rs 33.92 slab), installing solar that brings you to 200 units a month moves you to the Rs 18.95 slab — the marginal per-unit savings are smaller than you expected.
Conversely, if you are at 700+ units paying Rs 42.72 per energy unit, the first 300 units of solar self-consumption save Rs 60/unit all-in. That is why larger bills yield faster payback — you replace the most expensive marginal units first.
City-by-city: where solar pays back fastest
- Bahawalpur, Multan, RYK — highest peak sun hours (5.1+), shortest payback. Tube-well farms here recover cost in 2–3 years.
- Lahore, Faisalabad, Sialkot — 4.7 PSH, high domestic bills due to summer AC load. Average payback 2.5–3.5 yrs.
- Karachi (K-Electric) — higher TAC means higher effective tariff, faster payback. 5 PSH average.
- Islamabad, Rawalpindi (IESCO) — 4.5 PSH, slightly slower payback at 3–4 yrs.
- Quetta, Gilgit, Skardu — very high PSH (5.3+) but lower domestic bills due to lifeline slabs. Mixed picture; agri and commercial pay back fastest.

FAQ
What is the payback period for solar in Pakistan in 2026?
For a typical Lahore or Karachi home on the unprotected domestic tariff, a 10 kW on-grid system pays back in 2.5 to 3 years. A 10 kW hybrid system with 15 kWh LFP battery pays back in 3.5 to 4.5 years. Households over 600 units/month see the fastest payback.
Is bank financing for solar worth it?
For most middle-class Pakistani households, yes. PSB Solar Finance, Meezan Aasaan Solar and JS Bank Solar offer 5- to 7-year terms at ~15–16% effective. Monthly EMI is typically lower than the bill saving from day one, so net cash flow is positive throughout the loan.
How much can a 10 kW system save monthly?
A 10 kW on-grid system in Lahore or Multan generates ~1,400–1,500 units/month, saving Rs 38,000 to Rs 48,000 on the unprotected domestic tariff. Hybrid systems save slightly more by avoiding peak-hour TOU rates and outages.
Does net metering still make sense after the 2026 buyback rate change?
Yes. The new Rs 11/unit export rate lengthens payback by 6–12 months but does not change the core economics, because self-consumption still saves at full retail (Rs 22–60/unit). Right-size the system for self-use, not export, and the math still works.
What is the 25-year IRR on residential solar in Pakistan?
For a cash-paid 10 kW hybrid system in 2026, the 25-year IRR is typically 22–28%, depending on tariff slab, self-consumption ratio and DISCO. This far exceeds bank deposits, government savings certificates and most rental yields available in Pakistan.
Should I wait for solar prices to fall further?
Prices fell ~15–20% in 2025–26, but the next leg down is unlikely to exceed 5–8% in 2026–27. Meanwhile, every month delayed costs you Rs 25,000–70,000 in unrecovered bill savings. The math almost always says install now.
What happens if I sell my house with solar installed?
Net-metering connections are tied to the meter, not the owner. The new buyer inherits the system, the net-billing agreement, and any remaining bank financing (which can be cleared from sale proceeds). Pakistani property valuers in 2026 typically add 60–80% of installed solar cost back to the resale value.
