PV & BESS Factories Audited

From evidence to settlement.

Sinovoltaics holds the factory EL image of every module it inspected, per serial number. Field defects are traced to their origin - manufacturing, transport or installation - and presented to the OEM with evidence. A retainer-based claims practice for your fleet.

What claim management covers

Warranty claim management takes a suspected PV module defect from validation to settlement: warranty contract review, field EL/IR evidence collection, factory-baseline comparison per serial number, claim presentation, OEM negotiation and verification of the corrective action or replacement delivered.

Included:

  • Warranty contract & claim validity review - what your warranty actually covers, what evidence it requires, and which deadlines apply
  • Field EL / IR evidence collected to claim standard, compared against the factory EL baseline of the same serial numbers
  • Claim presentation & OEM negotiation - technically argued, in the manufacturer’s own quality language
  • Corrective-action & replacement verification - delivered remedies inspected before sign-off
  • Insurer- & lender-grade documentation throughout


Deliverables: claim validity assessment, evidence dossier per claim, negotiation representation, settlement verification report.

Why claims fail - and why ours don’t have to

Most PV warranty claims die on one of three hills:

  1. Origin. The OEM argues the damage happened in transport or installation - and without a factory baseline, nobody can prove otherwise.
  2. Evidence standard. Photos and monitoring data are opinions; warranty clauses demand defect documentation the manufacturer’s quality department accepts.
  3. Asymmetry. The manufacturer’s engineers negotiate module defects every week. Your asset manager does it once every few years.

Sinovoltaics closes all three. The SELMA factory-baseline comparison settles origin per serial number. Our field evidence is collected to the standard we know OEM quality departments apply - because we have audited more than 350 of their factories and speak their QC language from the inside. That is what “factory-side knowledge on your side of the table” means.

The result: claims resolved by negotiation, not litigation.

When you need this

  • Monitoring or annual inspections show degradation beyond warranty curves
  • EL findings from end-of-warranty campaigns need pursuing
  • An OEM has rejected or stalled a claim you believe is valid
  • Serial defects emerge across a fleet (glass breakage, PID, backsheet)
  • You want program-wide claims handled under one retainer instead of case-by-case fire-fighting


Engagement model

Program retainer plus per-claim fees. The retainer covers claim monitoring across the fleet - deadlines, degradation flags, serial-defect watch - so claims start from prepared positions instead of cold starts.

Frequently asked questions

  • Do I need Sinovoltaics factory data for a successful claim? No - it strengthens origin assignment decisively, but claims are regularly won on field evidence alone: EL defect patterns, statistical distribution across a delivery, and degradation measurements against warranty curves all carry weight.
  • What kinds of defects are typically claimable? Cell cracks and inactive areas beyond acceptance criteria, PID, LeTID, soldering and interconnect failures, backsheet defects, delamination, glass breakage from module-side causes, and performance below warranted degradation curves - always subject to your specific warranty terms.
