5 kW solar system price in Pakistan (November 2026)

What a 5 kW system produces

In Karachi a 5 kW system generates about 22 units a day on average, which is 670 units a month and 8,041 a year. That figure comes from the World Bank's Global Solar Atlas for Karachi, less 10% for dust and real-world losses. Hyderabad and Quetta produce more, Lahore and Islamabad less.

At the current residential tariff, 670 units bought from the grid cost about Rs 40,853 a month including surcharges and GST.

What it can run

A 5 kW system is the right size for a typical family home. In daylight it can carry two inverter air conditioners in daylight, plus fans, lights, a refrigerator, a TV, a water pump and a washing machine.

It suits homes using roughly 550 to 700 units a month, the most common size installed on houses in Pakistan.

Solar output follows the sun. It peaks around midday and is zero at night, so what the system can run depends on when you use power, not only on the monthly total. The solar load calculator works this out from your own appliances.

On-grid or hybrid

On a single-phase connection the system cannot export, so a hybrid system with a battery makes better use of the midday surplus. On three-phase, surplus can be exported under net billing.

An on-grid system has no batteries and switches off when the grid goes down. A hybrid system adds a lithium battery, here 5.1 kWh, which keeps essential loads running through load-shedding and stores midday surplus for the evening. For the full comparison see on-grid vs hybrid vs off-grid.

What changes the price

• Panel brand. Tier-1 panels sell for Rs 40 to 45 per watt. See solar panel prices.
• Inverter class. A premium inverter adds to the total. See inverter prices.
• Battery capacity. Each extra 5.12 kWh unit adds to a hybrid system. See battery prices.
• Structure. An elevated walk-under structure costs roughly twice a standard raised one.
• The site. Long cable runs, roof repairs and electrical upgrades are quoted after a survey.

Payback

If your home uses about 670 units a month, with 670 units of solar and 40% of your use in daylight, the on-grid system saves about Rs 21,668 a month in the first year and pays for itself in roughly 1.7 years. The hybrid system takes about 1.9 years, because the battery adds cost but also lets you use more of your own solar.

Those figures assume a three-phase connection exporting surplus at about Rs 11 a unit under net billing. Your own bill and daytime use will change them. Put your numbers into the ROI calculator.
