Before installing solar, you should understand your roof's suitability, a realistic budget for your system size, the net metering approval timeline, and how to verify an installer's credentials. Getting these four things right upfront prevents most of the delays and disappointments homeowners run into with solar projects in Islamabad and Rawalpindi.
1. Assess Your Roof and Usage First
Not every roof section is equally suitable — orientation, shading, and structural condition all matter, and your recent electricity bills determine what system size actually makes sense. A free site survey covers both, so avoid committing to a specific system size before this step.
2. Budget Realistically
- 3kW system: roughly PKR 600,000-900,000 installed, suited to smaller homes.
- 5kW system: roughly PKR 800,000-1,200,000, generating about 550-750 units/month.
- 10kW system: roughly PKR 1,500,000-2,200,000, for larger homes with higher usage.
These are approximate bands — always confirm an exact quote after a free site survey. See our detailed 5kW solar system cost breakdown for more.
3. Understand the Net Metering Timeline
Net metering approval through IESCO typically takes about 4-6 weeks from application to activation when documentation is complete, so factor this into your expected timeline alongside the 3-5 days typically needed for physical residential installation. Our IESCO net metering guide walks through the application steps in detail.
4. Vet the Installer's Credentials
Confirm the company is NEPRA certified (required for grid-tied installs), IESCO-approved for net metering, and ideally ISO 9001:2015 certified for quality management. Ask about warranty coverage — workmanship, panel performance, inverter, and mounting structure should all be clearly stated — and check their track record. Tripower has completed 500+ installations across the twin cities since 2014; see our guide on choosing the best solar company in Islamabad for a fuller checklist.
5. Plan for Ongoing Maintenance
Dusty conditions on busy corridors mean quarterly cleaning is a common baseline for maintaining output. Consider an Annual Maintenance Contract (Bronze, Silver, or Gold tiers) and confirm the installer offers responsive emergency repair — Tripower's response time in Islamabad is 2-4 hours.
Frequently Asked Questions
How long does the entire process take from start to finish?
Physical installation typically takes 3-5 days for a residential system, while net metering activation adds roughly 4-6 weeks on top when documentation is complete.
What documents do I need before starting?
You'll generally need recent electricity bills, property ownership or utility account details, and basic ID documentation for the NOC and IESCO net metering application, which our team helps prepare.
Should I get quotes from multiple installers?
Yes, comparing site surveys, warranty terms, and certifications across installers helps you make a confident, well-informed decision before committing.
