Simplify's Take
What believers are saying
- Kiwa reported €1.7 billion revenue in 2025, up 14% with 5% organic growth.
- Kiwa signed a €1.3 billion CSA TIC acquisition on August 28, 2026.
- The 2026 Northern Europe deal spree adds Germany, Denmark, Finland, and Lithuania immediately.
What critics are saying
- CSA’s acquisition needs member approval and regulatory clearance before closing, delaying integration into 2027.
- UL Solutions, SGS, and DNV attack Kiwa’s margins with broader brands and deeper procurement reach.
- A shift to in-house AI compliance at OEMs compresses Kiwa’s core certification fees.
What makes Kiwa unique
- Kiwa’s 12,000 employees span 40 countries, combining TIC scale with local regulatory depth.
- Kiwa PVEL’s Product Qualification Program gives solar buyers failure-focused module reliability data.
- Sertio, PÜG, and Valcert deepen Kiwa’s EU medical-device and certification capabilities in 2026.

↑ 31%Testaus- ja tarkastusyritys Kiwa has acquired Sertio, a Tampere-based in vitro diagnostics assessment company. Sertio operates as a notified body under the EU's IVDR regulation, evaluating medical devices for compliance before market entry. Kiwa is amongst the world's leading testing, inspection and certification companies. The acquisition strengthens Kiwa's position in the medical device assessment sector. Financial details of the transaction were not disclosed.
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.
The total number of Top Performers remains steady, but failures have increasedNAPA, Calif., June 4, 2025 /PRNewswire/ -- Kiwa PVEL, the independent lab for quality and reliability testing of solar photovoltaic (PV) modules, today announced the publication of its 11th annual PV Module Reliability Scorecard. This digital resource provides solar industry stakeholders with testing insights gained from Kiwa PVEL's flagship Product Qualification Program (PQP). The PQP is a comprehensive suite of extended reliability and performance tests that evaluate solar modules under a wide range of environmental and mechanical conditions—including the effects of extreme temperatures and high humidity, as well as the impacts of mechanical stress, hail and ultraviolet light
