Yoha Solar’s flagship YHMT-A+A+A+ long-pulse PV module IV tester (solar module tester / solar simulator) has passed rigorous metrological verification conducted by the Fujian Metrology Institute (National PV Industry Metrology and Testing Center). The device has obtained the industry’s highest triple A+ certification, confirming that Yoha Solar’s PV testing accuracy, operational stability and professionalism remain at the national top level.
As core testing equipment for the photovoltaic industry, solar simulators determine the authority and reliability of PV module power testing and performance calibration. The triple A+ grade represents the highest industrial standard, imposing extremely strict requirements on spectral matching, irradiance uniformity and irradiance stability. This national-level certification serves as official authoritative recognition of Yoha Solar’s R&D strength and product quality.
According to the official test report, the YHMT-A+A+A+ fully complies with the IEC60904-9:2020 international standard with all core parameters reaching A+ grade. It covers a spectral range of 300~1200nm, with irradiance non-uniformity ≤1%, irradiance instability ≤0.5%, test result consistency ≤0.5%, and electrical measurement error ≤1%. Unlike conventional flash testers, the equipment adopts a 10~100ms long-pulse light source that accurately simulates continuous solar irradiation and eliminates measurement errors caused by the capacitive and thermal effects of short-pulse testing.
Featuring an advanced technical architecture, the simulator offers an effective testing area of 2300×1200mm, suitable for medium and large-size, bifacial and tandem modules, as well as high-capacitance cell technologies including HJT and TOPCon. It effectively solves the industry pain points of inaccurate testing and poor compatibility encountered by traditional equipment when testing advanced PV products. Equipped with high-precision temperature monitoring and automatic calibration systems, the device precisely calibrates all test data to Standard Test Conditions (STC). Integrated automatic control ensures both superior precision and high throughput, adapting to mass production, scientific research and third-party certification scenarios.
With years of expertise in PV testing equipment, Yoha Solar consistently iterates products to address industrial testing challenges through technological innovation. The renewed triple A+ national certification further validates the outstanding performance of the company’s equipment and strengthens its core competitiveness and market credibility in the PV testing sector.
Moving forward, Yoha Solar will continue to focus on new energy testing technology innovation, optimizing high-precision, high-stability and intelligent PV testing equipment. The company will provide reliable hardware support for PV production quality control, new product R&D and authoritative certification, empowering the standardized and high-quality development of the global photovoltaic industry.
