Solar panel installation cost per kW in Pakistan (2026): what is inside the quote

• Panels: the largest share. Brand (Longi, Jinko, JA, Canadian, Trina), wattage per panel, and whether they are A-grade or "second-hand new"
• Inverter: on-grid (cheapest, no backup), hybrid (works with batteries, backup during load-shedding), or off-grid
• Structure: standard iron frame on a flat roof, or an elevated structure that lets you use the roof beneath and catches more wind
• Wiring, DC and AC breakers, surge protection and earthing: the cheapest place to cut corners and the most dangerous
• Labour and commissioning, including the app setup for monitoring
• Net metering paperwork and the bidirectional meter, if you want to sell units back

Panel prices follow the international module price and the rupee-dollar rate; inverter prices follow the same plus import duty. Installers buy stock in dollars and quote in rupees, so a quote from March is not valid in July. Always ask how long a quote is valid and whether the price is fixed once you pay the advance.

Most homes are sized on the last three bills, which is right, but they forget what they will add: a new inverter AC, an electric car in two years, or a water motor moving to solar. Oversizing a little is cheap at installation time and expensive later. Also count the roof: a 5 kW system with 580 W panels needs roughly nine panels and their spacing; a shaded roof needs a redesign, not a discount.

With net metering your daytime surplus goes to the grid and offsets units you draw at night. The policy, the tariff paid for exported units and the approval time change with government decisions, so ask the installer what the current rule is in your DISCO (K-Electric, LESCO, IESCO and so on) and whether they handle the application. Without net metering, a battery-backed hybrid system makes more sense than a large on-grid one.

Post the job with your last bill's units, your roof size and direction, whether you want night backup, and your city. Registered installers reply with their own price. Ask each for the same breakdown: panel brand and wattage, inverter brand and model, structure type, cable brand, warranty in writing for panels, inverter and workmanship, and who applies for net metering. Then compare per kW of the same specification. The cheapest quote with a different inverter is not the cheapest quote.
