Solar at a glance in Pakistan
High-wattage bifacial panels (550–710 W) are now standard in Pakistan, and payback periods of roughly 2–4 years are common at current tariffs.
| Currency | Pakistani rupees (PKR) |
|---|---|
| Typical electricity rate | Rs 55 per kWh |
| Installed cost | ≈ Rs 150 per watt |
| Peak sun hours | ≈ 5.6 hours/day |
| Export / buyback | ≈ Rs 11 per kWh |
Indicative 2026 starting points — every figure is editable in the calculator, and results depend on your own bill, roof and installer quotes.
A typical 5 kW system in Pakistan
At around Rs 150 per watt, a 5 kW rooftop system costs roughly Rs 750,000 and produces about 7,972 kWh in its first year at Pakistan's 5.6 peak sun hours a day. Your real numbers depend on your roof, shading, panel choice and how much power you use during the day — run your own figures in the calculator to see your exact payback, net savings and ROI.
How the solar calculator works
- Your setup. Pakistan and Pakistani rupees are pre-selected, with local electricity rate, install cost and sun hours filled in. Enter your monthly bill, or size the system from your appliances.
- Your roof. Search your address or tap “use my location”, then draw your roof on the satellite map — or just type its area. We check the system fits and read local sun hours from NASA data.
- Your results. Instantly see your payback period, net savings, ROI, system size, year-1 production and lifetime CO₂ offset — compare cash vs. a loan, and download a PDF report.
Common questions — solar in Pakistan
How many solar panels do I need in Pakistan?
It depends on your electricity use, roof space and local sun hours (about 5.6 peak sun hours/day here). A 5 kW system of high-wattage panels is a common starting point for a home — enter your bill or appliances and the calculator gives your exact panel count and system size.
Does Pakistan have net metering?
Yes. Net metering is available nationwide for connections of 1 kW to 1 MW through your DISCO (K-Electric, LESCO, IESCO and others). You export surplus units to the grid and net them off your bill; approvals typically run through NEPRA-licensed installers.
Are there solar subsidies or incentives in Pakistan?
There is no national cash subsidy — the economics come from net metering plus a favourable buyback and the high retail tariff you avoid. Some provincial and bank-financed instalment schemes appear from time to time.
How much does a solar system cost in Pakistan?
As a rough guide, a typical 5 kW rooftop system costs around Rs 750,000 at current installed prices of about Rs 150 per watt. Your exact figure depends on panel choice, inverter, structure and whether you add batteries — the calculator prices your own size.
Is solar worth it in Pakistan?
For most grid-tied homes on a rising tariff with net metering, yes — payback commonly lands in the 2–4 year range and the panels keep producing for 25+ years. Enter your bill to see your own payback and net savings.
