Yoha Solar has secured another successful project delivery. On June 10, the company’s self-developed laboratory PV module IV tester completed commissioning and shipment, and was officially deployed in a well-known domestic university laboratory. The equipment supports cutting-edge scientific research, project research and experimental teaching system upgrading in the photovoltaic field. The deployment of this high-precision testing equipment fully demonstrates Yoha Solar’s solid technical accumulation and product competitiveness in the field of precision PV testing equipment, providing high-precision, high-stability and high-reliability professional hardware support for universities in new PV module R&D, precise performance testing and academic achievement verification.
laboratory PV module IV tester
Accurate performance testing is the core foundation for PV technology iteration, product performance optimization and research data verification, whose precision directly determines the authenticity and effectiveness of PV R&D and inspection. Traditional flash IV testers suffer from excessively short pulse duration, which cannot eliminate capacitance and thermal effect errors generated by emerging high-capacitance modules, resulting in large test deviations. Such equipment fails to meet the precision testing requirements of mainstream high-efficiency PV modules, including bifacial, tandem, perovskite, HJT and TOPCon modules. Targeting this long-standing industry pain point, Yoha Solar has developed and iterated the laboratory PV module IV tester. Adopting innovative millisecond-to-second level long-pulse light source technology, the equipment highly simulates continuous solar irradiation conditions, fundamentally eliminating various test errors of traditional flash testers and enabling laboratory test environments to be highly consistent with the actual outdoor power generation status of PV modules.
High-precision electrical performance testing meets the needs of laboratory research
In terms of core configurations and technical parameters, the equipment strictly complies with international industry standards and achieves top A+ grade overall performance. Its light source fully meets the IEC60904-9:2020 international standard, with a spectral coverage of 300~1200nm. The standard test irradiance reaches 1000W/㎡ and is flexibly adjustable within the range of 200~1200W/㎡ to adapt to diverse test conditions. It features light intensity non-uniformity ≤1% and light intensity instability ≤0.5%, with an effective test area of 1500×900mm, supporting the overall testing of large-size PV modules and fully adapting to university laboratory research scenarios. Equipped with an external high-precision temperature sensor, the equipment dynamically monitors module operating temperature in real time and automatically calibrates test data to Standard Test Conditions (STC), ensuring the universality and comparability of test data from different environments and batches.
