Start to finish, a residential solar project takes roughly 6-10 weeks from your first site survey to net metering activation. The physical installation itself is fast — just 3-5 days — but the full timeline also includes design, documentation, and IESCO's net metering approval process, which is the biggest single chunk of time.
The Full Journey: Site Survey to Net Metering
A complete solar project follows six stages: (1) a free site survey, (2) custom system design, (3) proposal and agreement, (4) documentation, NOC and IESCO paperwork, (5) professional installation, and (6) commissioning with net-meter activation and customer training. Each stage has to be completed properly for the next to move forward without delay.
Step-by-Step Timeline Breakdown
- Site survey and design: typically a few days to a week, depending on scheduling and roof complexity.
- Proposal and agreement: a few days, once you've reviewed the quote and design.
- Documentation and IESCO paperwork: submitted after agreement, running in parallel with procurement.
- Physical installation: 3-5 days for a typical residential system.
- Net metering activation: roughly 4-6 weeks from application when documentation is complete — this is the longest stage.
What Can Speed Up or Slow Down the Timeline
Complete, accurate documentation submitted early keeps the IESCO approval stage on track; missing paperwork or roof access issues are the most common causes of delay. Working with a NEPRA-certified, IESCO-approved installer with established processes — such as Tripower, with 12+ years of experience and 500+ installations across Islamabad and Rawalpindi — reduces the risk of avoidable holdups.
The Physical Installation Itself Is Fast
If you're mainly asking how many days a crew will be on your roof, that part is short: 3-5 days for a residential system. For a detailed look at exactly what happens during those installation days, see our guide on how long the physical solar installation actually takes.

Frequently Asked Questions
Why does net metering take longer than the installation itself?
Net metering activation depends on IESCO's own review and approval process, which typically runs 4-6 weeks and is outside the installer's direct control, unlike the on-site installation work.
Can I use my solar system before net metering is activated?
Yes, the system can generate and power your home once commissioned, but you won't receive export credit for surplus units until net metering is officially activated.
Does a larger system take longer to install?
Larger residential systems may add a day or two to the on-site installation, but the overall 6-10 week timeline is driven mainly by documentation and net metering approval, not system size.
