Sources and data governance

Source types include official publications, supplier-published data, installer submissions, user submissions, verified quotations, and SolarGabay planning estimates. Records should show observation date, location and product scope, confidence, review date, and expiry.

Installer discovery uses a local static public-source directory. Public-source checking confirms listed public details, not workmanship, pricing, engineering quality, or customer outcomes.

Expired records are labeled or excluded. Public users cannot modify approved records directly, and sponsorship cannot change source quality or editorial conclusions.

When sources disagree, SolarGabay prefers the most authoritative and current document, records the conflict, and avoids presenting the disputed value as settled fact. Readers can submit corrections with the affected URL and supporting evidence through the corrections page.

Primary-source preference means official Philippine laws, regulations, utility publications, manufacturer documentation, and original public company pages are used before summaries when they directly support the claim. International government and research publications may provide technical context, but they do not establish a Philippine price, approval, credential, or legal requirement.

Every public-source installer record identifies its source path and review date where available. A successful source check confirms only that the cited public information could be found at review time; it does not verify licensing, financial condition, engineering competence, workmanship, customer satisfaction, or present availability.

Readers should verify time-sensitive information at the decision date. Utility processes, tariffs, product specifications, warranties, company contacts, and government requirements may change after the displayed review date.
