verified_userVerification & Trust Scoring
Unlike open listing sites, Solar Directory employs a rigid Identity Verification Process. A company profile must meet specific data-density thresholds ("Quality Gate") to be indexed in our public search results.
1. The 'Verified' Badge
The blue checkmark is not for sale. It is earned through:
- Identity Match: Matching VAT/Tax ID with official business registries.
- Domain Authority: Verification of website ownership via DNS or file upload.
- Physical Presence: Confirmation of operational address.
2. Quality Gate (Indexation Policy)
To prevent "thin content" and ensure user value, unverified profiles are only indexed if they contain significant unique data (e.g., service portfolios, project galleries, detailed descriptions > 80 words). Low-quality stubs are strictly noindexed.
monetization_onNo "Pay-for-Rank"
Solar Directory does not artificially alter search rankings based on payments. Our search algorithms prioritize relevance, completeness, and verification status. Sponsored placements, if any, are clearly labeled as "Ad".
gavelEditorial & Data Policy
We treat solar market data as operational infrastructure. Our editorial standards ensure that professionals can rely on this directory for business decisions.
Data Sourcing
Data is aggregated from official public registries, direct user submissions, and partner integrations (e.g., certification bodies). All programmatic data is flagged and subject to human review upon "Claim" request.
Correction Protocol
Verified business owners have absolute write-access to their profile data. Public disputes are adjudicated by our compliance team within 48 hours.
Spam & Abuse
We employ automated heuristic analysis to detect and ban:
- Keyword stuffing in descriptions.
- Fake reviews (detected via IP/fingerprint clustering).
- Duplicate listings (resolved via canonical grouping).
Frequently Asked Questions
- How does the Solar Directory verification process work?
- Every company goes through a three-step verification: (1) Identity Match — we confirm the business registration number and legal name against national company registers; (2) Domain Authority — we verify the company's web presence and contact channels are consistent; (3) Physical Presence — we confirm a real operating address in the listed region. Verified status is reviewed annually.
- What does the "Verified" badge mean on Solar Directory?
- A Verified badge means Solar Directory has independently confirmed the company's legal registration, physical address, and active business status in their listed country. We do not accept payment for Verified status — it is awarded solely based on our editorial review criteria.
- How do I choose a solar installer in :province?
- Look for verified companies with a confirmed physical address and VAT registration in :province. Solar Directory marks these with a blue Verified badge. Compare at least three quotes, check customer reviews, and confirm the installer is certified for your country's grid connection standards before committing.
