Solar Panel Calculator Pakistan

By Shehzad Hussain

Solar panel calculator for Pakistan: size your system with Pakistan sun hours (5.5), local tariffs and Rs costs, plus net metering notes.

Your electricity use

How do you want to enter your usage?

Monthly electricity bill (Rs)

Electricity rate (Rs per unit)

Your roof & system

Peak sun hours per day

Panel wattage (W)

System losses (derate, 0–1)

Installed cost per watt (Rs)

Estimates only. System size, production, savings and payback are estimates based on the assumptions shown with your results — real output depends on your roof, shading, weather and local rates. Pakistan net metering lets you export extra units to the grid — check your DISCO's current buy-back rate, it changes. Incentives vary by state/country and change — check current local rules. Get a quote from a licensed local installer before deciding.

How the Pakistan solar calculator works

Same formula, Pakistan numbers. The calculator uses Pakistan defaults: 5.5 peak sun hours a day, Rs 45 per unit, about Rs 160 per watt installed, and 550W panels (common in Pakistan). A home using 500 kWh a month needs 16.67 ÷ 5.5 ÷ 0.78 = 3.88 kW — 8 panels at 550W, a 4.4 kW system covering about 144 sq ft of roof.

Yearly production is about 6,890 kWh. Estimated savings are about Rs 290,019 a year, and the Rs 704,000 system pays back in about 2.4 years — short by world standards, because Pakistan combines strong sun with high grid tariffs. Your own payback depends on your tariff slab and usage.

Pakistan net metering lets you export extra solar units to the grid through your DISCO under NEPRA regulations and get credit on your bill. The buy-back rate changes, so check your DISCO’s current rate — this calculator assumes exported units earn half your import rate.

Prices vary widely by city, panel brand and installer — always get three local quotes. Read the full guide: solar panels in Pakistan, or size a US/UK system with the main solar panel calculator.

How to use the Solar Panel Calculator Pakistan

Enter your monthly electricity bill in Rs (check your DISCO bill).
Keep peak sun hours at 5.5 — Pakistan is one of the sunniest countries for solar.
Set your tariff (Rs 45 per unit is the default) and panel wattage (550W is common in Pakistan).
Read off your system size, panel count, roof area, yearly production and estimated cost in Rs.

Frequently asked questions

How many solar panels do I need in Pakistan?

A home using 500 kWh a month needs about 8 panels at 550W — a 4.4 kW system covering about 144 sq ft — at 5.5 peak sun hours. Pakistan needs fewer panels than the US or UK for the same usage because the sun is stronger.

How much does a solar system cost in Pakistan?

At about Rs 160 per watt installed, a 4.4 kW system costs about Rs 704,000. Prices vary widely by city, panel brand and installer — always get three local quotes before you buy.

What is net metering in Pakistan?

Net metering lets you export extra solar units to the grid through your DISCO (distribution company) under NEPRA regulations, and get credit on your bill. The buy-back rate changes, so check your DISCO's current rate — this calculator assumes exported units earn half your import rate.

How long is solar payback in Pakistan?

Often very short by world standards. For the 500 kWh a month example, estimated savings are about Rs 290,019 a year against a Rs 704,000 system — a simple payback of about 2.4 years. High tariffs and strong sun are the reason. Your own payback depends on your tariff slab and usage.
