What Halm Elektrotechnik does
Halm Elektrotechnik (legal entity halm elektronik gmbh) is a German manufacturer of IV (current-voltage) measurement systems and solar simulators used by photovoltaic cell manufacturers, module producers, and PV research and certification institutes. Founded in 1981 in Frankfurt am Main and reorganized as a GmbH in 1984, the company is owner-managed by brothers Moritz and Michael Meixner following a 2018 management buyout. It operates from a single Frankfurt manufacturing site where all products are engineered and assembled, supplemented by a wholly-owned subsidiary in Suzhou (h.a.l.m. elektronik (Suzhou) Ltd., founded 2010) and a network of channel partners in China, Korea, Taiwan, and India.
The product portfolio is organized across four application segments — cell production, cell lab, module production, and module lab — built on a modular, upgradeable hardware architecture and unified by in-house software (PVControl supplied standard, PVCockpit offered as an optional factory-wide monitoring tool). Core systems include the IUCT-SoluX-S/BF for high-throughput cell production (up to 5,500+ cells/h), the IUCT-LF3.1 and Celltest4/5 for cell and tandem/perovskite R&D, the IUCT-Q2 and IUCT-M-L for module production, and the Moduletest4 and Moduletest-QD for module R&D and certification. Differentiated technology elements include proprietary hysteresis capability for single-flash high-capacitance measurement, an LED light source with 28+ wavelengths spanning 300-1,200 nm, and A+A+A+ certification to IEC60904-9 Edition 3.0 across the current lineup. The 2025 acquisition of neonsee's high-collimation xenon light technology has extended the offering into aerospace, automotive, and space-grade (AM0) testing.
Halm sells high-end bespoke-configured systems through direct enterprise sales from Frankfurt and via regional channel partners, with 95% of production exported. Revenue is generated from hardware sales, optional software licenses and add-ons (PVControl/PVCockpit, EL and IR imaging packages, Therm-package temperature control), and recurring service contracts. Over 2,000 systems and 250+ GW of cumulative production cell testing capacity have been delivered worldwide. The company holds ISO 9001 and ISO 14001 certifications, employs approximately 125 people in total, and does not disclose financials.

Halm Elektrotechnik competitors and assessment
Company assessmentDirect peers
- Endeas Oy: Finnish manufacturer of solar simulators and IV testers for PV cell and module characterization. Closely comparable product portfolio (Quick Sun, Pasan flash testers) serving the same production and lab customer base as halm, with overlapping IEC certification positioning.
- Abet Technologies: US-based manufacturer of solar simulators and light sources for PV testing, including steady-state and pulsed systems. Comparable to halm across both LED and xenon technologies for cell/module R&D and certification applications.
- Sinton Instruments: US-based specialist in PV lifetime and Suns-Voc measurement, now part of ECA Group. Directly comparable to halm as a high-precision PV cell characterization equipment maker serving research institutes and cell manufacturers with complementary test methodologies.
- Pasan (Meyer Burger): Pasan, now part of Meyer Burger, is a Swiss-based supplier of high-throughput flash testers for solar cell and module production. Directly competes with halm's IUCT and Celltest lines for the same GW-scale PV manufacturer customer base.
- Bentham Instruments: UK-based manufacturer of spectroradiometers, monochromators, and EQE measurement systems used in PV cell characterization. Directly comparable in R&D-laboratory PV measurement, overlapping with halm's Celltest and Moduletest product lines.
Broad incumbents
- Chroma ATE: Taiwanese-listed broad test-and-measurement equipment maker with PV production-line testing products. Overlaps with halm in PV IV testing, particularly in Asian cell/module manufacturing, but operates across many other test verticals (electronics, automotive, batteries).
- Keysight Technologies: Global leader in electronic test and measurement instrumentation with PV-related products. While not specializing in solar cell/module flash testers like halm, Keysight competes for the broader characterization and power-measurement budget of large PV manufacturers and research institutes.
Emerging players
- G2V Optics: Canadian startup developing programmable LED solar simulators for PV testing with a focus on spectral accuracy and software integration. Comparable to halm's Celltest5 and Moduletest-QD platforms, though younger and with narrower product depth.
- Newport / MKS Instruments: Supplies Oriel solar simulators and light sources used in PV research and certification labs. Comparable to halm in steady-state solar simulation and spectroscopy applications, particularly through the Oriel product line for aerospace and AM0 spectrum testing.
Others
- Spectrolab (Boeing): Boeing subsidiary and leading manufacturer of space-grade solar cells. Not a direct competitor but represents the customer-side counterpart in aerospace/space PV — relevant to halm given the neonsee acquisition targeting AM0 and satellite solar cell testing.
