IESCO Net Metering: Islamabad & Rawalpindi Guide
IESCO covers Islamabad, Rawalpindi and the surrounding districts up to Attock, Jhelum and Chakwal. The capital region combines decent sun with a cooler climate that panels actually like — plus two local considerations worth designing for.
The IESCO process
- File through an AEDB-certified installer: CNIC, recent bill, single-line diagram, datasheets.
- Application lands with your IESCO sub-division; inspection follows to verify earthing, protection and equipment.
- Demand notice for the bidirectional meter and processing — get the current figure in writing before starting.
- Meter installation and interconnection agreement; export credits begin on subsequent bills.
Designing for the capital region's climate
Steeper tilt pays here. At ~34° latitude, the ideal fixed tilt is noticeably steeper than in Karachi or Multan — flat-ish installs give away real winter production. Hail happens. The region sees occasional hailstorms; specify panels with certified impact ratings and avoid ultra-thin budget glass. The upside: cooler temperatures mean panels here suffer less heat derating than in south Punjab — summer output holds up well.
Sizing under net billing
Islamabad averages roughly 4.8 peak sun hours. As everywhere under net billing: size near daytime usage, push flexible loads into solar hours, and verify the economics of any quotation before committing.
