Islamabad solar estimate at a glance
This shared model uses 5.1 peak-sun hours per day, a 75% performance ratio, 55% direct self-consumption, Rs. 60/unit retail value, and Rs. 8.13/unit export credit. These are illustrative assumptions, not an official flat IESCO tariff. Enter the actual units from your bill, then ask your installer to recalculate savings using your agreement rates and measured daytime load.

Local sizing notes
What changes in Islamabad
Islamabad uses a 5.1 peak-sun-hour planning default. In tree-lined sectors or a sloping site, request a monthly generation estimate that uses the roof's actual orientation and horizon. The same annual assumption can hide quite different winter shade on a low roof and a clear upper roof.
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.

Area names are examples for survey planning. Verify the actual electricity supplier on your own bill.
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.
Site survey
Evidence to request for a Islamabad roof
Use your own bill, roof photographs and operating schedule to turn these local checks into a written design. Ask for the evidence behind each proposal before comparing total prices.
Model tree shade at winter sun angles
Have the survey identify trees on and beyond the plot, their height relative to the array and expected growth. Ask for winter shade times for each roof plane. An optimizer proposal should identify the affected modules and its added cost rather than assume every module needs one.
Keep differently oriented roof sections identifiable
For split roofs, request a drawing linking each roof plane to its inverter input and a separate yield assumption for shaded sections. Include drainage and roof-penetration waterproofing in the scope before monsoon weather; usable area is smaller than total plot area.
A comparison to make before you buy
For an F-sector home with mature trees, compare an array limited to the clear upper roof with an array spread across both roof levels. Ask for the extra shaded modules' marginal annual output and mounting cost. A smaller clear array can be the better quote even when the calculator suggests room for more capacity.
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
Answers to local planning questions before you request a quote.
How should tree shade be checked in Islamabad?
Request a shade map for each roof plane at winter sun angles, with tree heights and expected growth. A photograph taken only at noon in summer is insufficient for a year-round layout.
Can different Islamabad roof levels use one yield assumption?
Each roof plane may have different orientation and shade. Ask for separate yield assumptions and a drawing showing the strings and inverter inputs.
Official sources
Verify the application and generation assumptions
Use the original utility sources for application rules, fees and approval steps. The sun-hours and price bands on this page are this site's planning assumptions; they are not an official tariff or a measured local yield dataset.
IESCO official net-billing portal
PITC lists IESCO among its supported utilities and links applications, tracking, NEPRA regulations, contact information and transformer checks. Read the current notices before a new application or capacity change.
Check monthly yield in Global Solar Atlas
Select your roof's location and compare monthly PVOUT for the proposed orientation and tilt. The Atlas model excludes building and vegetation shade, so a local shade survey is still needed. Its kWh/kWp yield is a different quantity from this calculator's peak-sun-hour input.
