How to Choose a Solar Installer in Quezon City: 12-Point Checklist
Compare installers on engineering, permits, scope, warranties, and after-sales — not just the lowest package price.
Last updated: July 2026 · Quezon City-specific planning guidance. Equipment availability, permitting rules, and prices can change.
Direct answer: choose the installer who can prove the whole project
The best solar installer in Quezon City is not automatically the cheapest or the biggest. Choose a team that can show a site-specific design, itemized scope, realistic Meralco and QC permit process, named equipment, structural and electrical competence, clear warranties, monitoring handover, and responsive after-sales. Use this 12-point installer checklist before signing.
The 12-point scorecard
| Check | Ask for | Pass signal |
|---|---|---|
| 1. Local coverage | Barangay/service area | Clear QC response and site logistics |
| 2. Site assessment | What gets measured? | Roof, shade, panel, load, bill |
| 3. Design | Single-line / layout | Site-specific, not generic |
| 4. Scope | Itemized quote | Permits, NMP, commissioning visible |
| 5. Equipment | Brands/models | No vague “premium” labels |
| 6. Roof | Mounting method | Roof-type assumptions documented |
| 7. Permits | Who files? | QC OBO + Meralco roles stated |
| 8. Timeline | Milestones | Dependencies explained |
| 9. Warranty | Three layers | Panel, inverter, workmanship |
| 10. Monitoring | Handover | Owner gets access and training |
| 11. After-sales | Response process | Named contact / escalation |
| 12. References | Relevant examples | Evidence, not only logos |
Red flags
- A price without kWp, equipment, exclusions, or permit scope.
- Guaranteed bill elimination or fixed payback without bill/site data.
- Pressure to pay a large deposit before an assessment.
- No answer about brownout behavior or anti-islanding.
- No written workmanship warranty or after-sales process.
How to compare two credible bids
Normalize system size and equipment class first. Then compare quotes using the scorecard, inspect line items, and check warranty handling. A higher quote can be better value if it includes engineering and utility work that the lower bid excludes.
Frequently asked questions
Should I use a nationwide brand or local installer?
Both can work. A QC-focused team may offer faster local assessment and barangay familiarity; a national company may offer wider procurement and support. Judge the actual engineering, scope, and service response.
How many quotes should I collect?
Two or three comparable quotes are usually enough. More quotes help only when each has the same inputs and complete scope.
