These planning numbers use IESCO city assumptions, 5.1 peak-sun hours per day, a 75% performance ratio, Rs. 60/unit retail value, and Rs. 11/unit export credit. Final quotes should still be verified by site survey.

Local sizing notes
What changes in Islamabad
Islamabad's 5.1 peak-sun-hour assumption is conservative enough for many residential rooftops across F sectors, G sectors, E-11, Bahria Enclave, and DHA Islamabad.
Trees, hillslope orientation, parapet shade, and multi-level roofs can matter more than the city average. A good quote should include roof photos, panel rows, and string design.

Net billing
IESCO savings logic
IESCO customers should compare self-consumption, exports, and imports line by line. Daytime appliances and work-from-home load can improve savings under net billing.
The calculator separates direct savings from export credit because imported units and exported units have different cash values. This is why two Islamabad homes with the same kW size can have different payback.
Quote checklist
Before you sign a Islamabad solar quote
Keep every installer on the same scope. Otherwise a cheaper quote may simply be missing protection gear, stronger mounting, monitoring, battery wiring, or IESCO paperwork.
1
Confirm the IESCO filing scope, fees, drawings, testing, inspection, and bidirectional meter timeline.
2
Ask for panel brand, exact model, wattage, serial verification, product warranty, and performance warranty.
3
Require inverter make, model, warranty channel, monitoring access, surge protection, earthing, and breaker details.
4
Separate panels, inverter, mounting, protection gear, battery, labor, and net-billing filing into line items.
5
Ask Islamabad installers for IESCO filing responsibility, structural wind loading, inverter placement, monitoring access, and expected approval timeline.
FAQ
Islamabad solar calculator questions
Short answers for the searches people make before they request quotes.
What solar generation assumption is used for Islamabad?
This page uses 5.1 peak-sun hours per day for Islamabad. Treat it as a planning average, not a guaranteed daily output.
Does shade matter more in Islamabad?
Yes. Trees, slopes, and split roofs can create partial shade, so string design and optimizer decisions may affect real output.
