What WAVELABS does
WAVELABS, headquartered in Leipzig, Germany, develops and manufactures LED-based solar simulators used to characterize and test photovoltaic cells and modules. Founded in 2011, the company pioneered the transition from xenon-flash to LED-based solar simulation and has built an installed base of more than 1,000 devices across 32+ countries, capturing approximately 30% of the global cell measurement systems market. The product portfolio spans the SINUS series (SINUS-70, SINUS-230 LIGHT, SINUS-360 PRO/ADVANCED, SINUS-430 ADVANCED, SINUS-1000 ADVANCED, and SINUS-3000 PRO/ADVANCED), covering R&D cells, mini-modules, and full-size modules, complemented by the Flashboard ML-based production analytics software and tailor-made custom solutions.
The business operates a direct B2B sales model targeting solar cell and module manufacturers, research institutions, and certification laboratories. Revenue is generated primarily through high-precision hardware sales with quote-based pricing, supplemented by service, calibration, and maintenance contracts on the installed base. Key enabling technologies include the patented RapidWAVE IV characterization method (enabling 30ms measurement of HJT, PERC+, and TOPCon cells), modular LED light engines with up to 27 individually controllable channels, and PTB-validated 0.9% measurement uncertainty. APAC coverage is delivered through regional channel partners in China (Suzhou JSUN), Korea (Woowon), Taiwan (Challentech), and SE Asia (Solsol Asia), with direct enterprise sales in Europe and the Americas.
In June 2025, the company's key assets were acquired by Dutch solar testing specialist Eternal Sun as part of a buy-and-build strategy enabled by Bolster Investment Partners' 80% acquisition of Eternal Sun. The combined entity operates as WAVELABS Eternal Sun GmbH, a 100% subsidiary of Eternal Sun Group B.V., serving manufacturers, laboratories, and developers across 60+ countries while maintaining WAVELABS and Eternal Sun as independent brands.

Broad incumbents
- Newport Corporation / MKS Instruments: Large diversified photonics and optics company offering Oriel solar simulators and related light sources as part of a broader portfolio spanning lasers, optics, and motion control. Serves similar R&D customers but does not specialize in PV cell/module production testing.
Emerging players
- Greateyes: German manufacturer of scientific cameras and imaging systems used in PV characterization (EL/PL imaging). Partial overlap with WAVELABS' tandem EL/PL imaging capability, focused on enabling components rather than full simulator systems.
- SPECTRAFY: Canadian developer of solar spectral irradiance measurement instruments (SunSim / HyperFlash) used for PV characterization and resource assessment. Emerging player with partial overlap in spectral measurement for solar cell characterization workflows.
Regional players
- Allreal (Suzhou) PV-Tech: China-based PV testing and metrology equipment supplier serving Greater China manufacturers. Regional competitor to WAVELABS' LED simulator portfolio with focus on Chinese cell/module fabs.
