Choosing a solar installer

A practical due-diligence checklist for Philippine property owners.

Author: SolarGabay EditorialReviewer: Solar Methodology TeamUpdated July 15, 2026

Summary answer

Choose an installer by checking legal identity, technical scope, equipment traceability, workmanship, warranties, support, and comparable production assumptions. Sponsorship or a directory badge must never replace due diligence.

What changes the answer

  • Business verification confirms identity records, not engineering or workmanship quality.
  • A complete quotation should identify equipment models, protection devices, mounting, labor, permits, and exclusions.
  • Production guarantees need clear assumptions, monitoring, remedies, and exclusions.
  • After-sales response, warranty claim handling, and documentation matter after installation.

Practical checklist

  1. Verify business registration, address, contacts, and responsible technical personnel.
  2. Request at least three comparable quotations and references for similar installations.
  3. Check equipment serial traceability, datasheets, warranty issuer, and local support.
  4. Do not pay based only on a social-media post, badge, review score, or sponsorship label.

Evidence and limitations

SolarGabay directory profiles identify the scope of each review. A public-source-checked listing confirms selected public details only; it is not a workmanship guarantee or customer endorsement.

Source transparency

Data should show source type, observation date, scope, confidence, and expiry.

Commercial separation

Sponsorship cannot change calculation assumptions, verification, or editorial conclusions.
