Partnerships

One partnership is on record.

• Avalon STcoreStrategic or Co-development Partner · 10 June 2025Avalon ST acquired Pasan SA in June 2025, combining Pasan's xenon heritage with Avalon's LED leadership under the Avalon ST group. Pasan continues as the premium xenon line for compliance, calibration, and reference labs; Avalon continues as the LED line for production, advanced research, and emerging chemistries. Both product lines remain distinct while sharing group resources. Operations continue from Neuchâtel (xenon engineering HQ) and Shanghai (LED).

Direct peers

• Endeas Oy: Finnish manufacturer of xenon flash solar simulators (QuickSun) for production-line and laboratory PV testing. Direct peer serving similar module manufacturer and lab customers, often selected as the principal alternative to Pasan in tier-1 production lines.
• Eternal Sun: Dutch LED solar simulator manufacturer (Spire Solar and Sunspot product lines) for production and laboratory PV testing. Direct peer because it competes head-to-head on A+A+A+ and A++ classifications using LED rather than xenon illumination.
• Wavelabs Solar Metrology Systems: German manufacturer of LED-based solar simulators (SINUS and LED-LIB) for cell and module measurement. Directly comparable as a non-xenon competitor challenging Pasan in production and R&D use cases with multi-junction and tunable spectrum capabilities.
• Abet Technologies: US manufacturer of xenon and LED solar simulators (Aurelia, Oriel-class) for research and laboratory PV measurement. Direct peer competing in the same xenon/Class AAA segment, particularly for research and certification use cases.

Emerging players

• Sinton Instruments: US-based supplier of lifetime and suns-Voc measurement tools for PV cell and module characterization. Comparable because it serves the same PV R&D and production metrology customers with adjacent measurement techniques (carrier lifetime, implied I-V).
• Ossila: UK supplier of solar simulators and PV test systems (including xenon and LED configurations) targeted at research and emerging PV chemistries including perovskites. Comparable as an emerging player addressing the same R&D/capacitive-cell measurement niche with a more standardized, lower-cost product.
• Avalon ST: Sister company within the same group since June 2025; Avalon ST manufactures LED-based solar simulators (Nexun line) targeting production and advanced research. Comparable because it addresses the same PV metrology market with a complementary technology stack.

Others

• UL Solutions (UL LLC): Global safety certification organization operating PV testing laboratories using Pasan reference systems. Comparable as an adjacent PV certification and testing player that depends on Pasan's reference measurement technology for its accreditation work.
• TÜV Rheinland: Global testing, inspection and certification body operating PV lab services (TÜV Rheinland Photovoltaic Testing Laboratory) and producing the 2025 module nameplate study. Comparable because it is both a Pasan customer (calibration/measurement systems) and an adjacent player in PV module certification and bankability reporting.

Broad incumbents

• Newport Corporation (MKS Instruments): US-based photonics/light-source giant (now part of MKS Instruments) offering Oriel solar simulators and Class AAA xenon/LED systems. Comparable as a broad incumbent in solar simulation and optical instrumentation, with much wider product breadth but less PV-specific focus than Pasan.
