Factory-to-field quality assurance, from delivery to end of warranty

Most field inspectors start from zero at your site. Sinovoltaics arrives with the factory records of your own equipment.

Since 2009, our engineers have inspected PV modules and battery systems on the factory floor - capturing 100% EL images, FAT performance baselines, serial numbers and bill-of-materials records for more than 25 GW of client equipment. Our field services connect that data to your operating assets: every field measurement is compared against the factory fingerprint of the same serial number, so damage and degradation are traced to their origin - manufacturing, transport, installation or operation.

Responsibility assigned, not argued.

Choose your technology

Solar PV Field Inspection & Testing → On-arrival inspection, construction QA, field EL testing, IEC 62446-3 thermography, annual plant health programs, end-of-warranty campaigns and warranty claim management for utility-scale PV across Europe.

BESS Field Inspection & Commissioning → SAT witnessing, annual site health & safety inspections, 100% rack-level capacity verification (BESSecure) and warranty validation against your FAT baseline.

Why owners choose Sinovoltaics in the field

  • The factory baseline. We hold factory EL images, flash data and FAT test results for the assets we inspect - evidence chains no field-only inspector can rebuild.

  • Independence. We work exclusively for buyers and owners. No manufacturing ties, no O&M contracts, no conflict of interest.

  • Accredited discipline. ISO 9001:2015 certified; inspection operations run to ISO/IEC 17020:2012 discipline.




  • European delivery. EU-based crews, mobilised per project, backed by the Asia factory teams that inspected your equipment at source.

  • Trust bar (site-wide): Active in Asia since 2009 · 25+ GW quality assured · 350+ PV & BESS factories audited · ISO 9001:2015 · ISO/IEC 17020:2012
