Simplify's Take

What believers are saying

  • In 2026, Kiwa added Sertio, PÜG, Valcert, Vesta, Electro-Test, and 360 Brandrådgivning.
  • Kiwa launched India Medical in 2026, expanding medical-device certification into a growing market.
  • Kiwa’s 2026 PVEL scorecard names 43 Top Performers, reinforcing its solar gatekeeper role.

What critics are saying

  • 2025 PVEL data showed 83% of manufacturers and 59% of BOMs failed at least once.
  • Solar module breakage rose in MSS and HSS, inviting customers to cut lab spending.
  • By 2027, PVEL pricing power erodes if manufacturers standardize around cheaper in-house testing.

What makes Kiwa unique

  • Kiwa’s 1948 water-safety origin still anchors trust in regulated testing and certification.
  • SHV’s 2021 backing funds acquisitions across Europe, medical devices, energy, and construction.
  • Kiwa PVEL’s independent scorecard shapes solar procurement with failure data, not marketing.

Kiwa PVEL updates solar module testing to tackle rising spontaneous glass breakage failures

Kiwa PVEL, an independent solar photovoltaic module testing laboratory, has released a major update to its Product Qualification Program addressing rising field failures from spontaneous glass breakage and frame structural issues. The revised programme introduces test-to-failure protocols for static mechanical load and hail testing, with expanded sample sizes to better assess module durability. The new hail test increases samples to five modules and focuses on breakage-prone areas like edges and corners, escalating hail diameters until failure occurs. The update also introduces final stabilisation steps to address measurement uncertainty in n-type technologies, including light-soaking treatments after various stress tests. Additional changes include reduced sample sizes for light-induced degradation testing and streamlined UV-induced degradation sequencing. The updates aim to provide solar buyers with more robust reliability data as manufacturers pursue larger modules with thinner materials.
