Editorial & research policy

Sources

Rules that change — CFE tariffs, interconnection requirements, distributed-generation regulation — are sourced from official authorities such as CFE and the CNE. Equipment claims come from original manufacturer documentation. Installer FAQs may help us identify questions, but are not treated as authorities.

What we won’t publish

No invented prices, outage statistics, savings or payback periods, survey data, testimonials, review scores, certifications or “verified” badges. If a fact can’t be verified, we omit it or explain the uncertainty.

Dates

Each guide shows its publication date and the date of its last substantive update. Cosmetic edits don’t change the update date.

Technical review

A guide only shows “technically reviewed” when a named reviewer has completed a review, with the date and scope stated. Guides currently show “Not technically reviewed yet”.
