Solar system cost calculator

Set the size, panel brand, inverter class, batteries and structure. You get an itemised estimate at November 2026 market rates, with a likely range.

Method

What the estimate includes

Solar panels. Whole 585 W panels at the per-watt rate of the brand you pick. Tier-1 N-type panels are selling at Rs 40 to 45 per watt in November 2026.

Inverter. Sized to the array and priced by class. On-grid inverters cost less than hybrid inverters of the same rating, because a hybrid unit also manages batteries.

Lithium batteries. LiFePO4 units of about 5.12 kWh each, priced per unit by brand. Only for hybrid and off-grid systems.

Mounting structure. A standard raised structure, or an elevated walk-under structure that keeps the roof usable and costs roughly twice as much per watt.

Cables and protection. DC and AC cable, breakers, surge protection and earthing.

Installation and commissioning. Labour, testing and handover.

Net billing fee. The concurrence fee of Rs 1,000 per kW under the 2026 regulations. The meter and the distribution company's own charges are extra and vary by company.

For ready-made prices by size, see solar system price in Pakistan, with separate guides for panels, inverters and batteries.

Not included. Civil work, long cable runs, transformer or HT works on large sites, and anything a site survey reveals. That is why the total is shown with a range of plus or minus 10%.

Questions

Cost calculator FAQ

01 · FAQ

Is this Mastoor Energy's price?

No. It is a market estimate built from dealer listings surveyed in November 2026. Our quotation depends on your site, the equipment available and the electrical works needed, and may be higher or lower.

02 · FAQ

Why does a hybrid system cost so much more than on-grid?

Two reasons. The hybrid inverter costs more, and the lithium batteries are a large part of the bill. Reduce the number of battery units to see the difference.

03 · FAQ

Which panel brand should I choose?

Longi, Jinko, Canadian Solar, JA and Trina are all Tier-1 manufacturers and their prices are within a few rupees per watt of each other. Availability and warranty support matter more than the small price gap.

04 · FAQ

Do I need the net billing fee?

Only if you want to export surplus units and have a three-phase connection. If you will use everything you generate, untick it.
