With the rapid development of renewable energy, photovoltaic modules are the core components of solar power generation, and their stability and performance reliability have become the key to industrial development. In order to evaluate the performance of photovoltaic modules under different environmental conditions, the International Electrotechnical Commission IEC has developed a series of international test standards. As an important testing equipment, the Photostability Chamber from Millennial Solar can simulate light attenuation under different environmental conditions, providing reliable environmental simulation for stability testing of photovoltaic modules.

Photovoltaic module stability test

Photovoltaic modules are the core components that convert solar energy into electrical energy. Their quality and performance directly affect the efficiency and reliability of photovoltaic power generation systems. The photoelectric conversion efficiency, durability and stability of photovoltaic modules are important indicators for evaluating their performance. In order to ensure that photovoltaic modules can operate stably and have long-term reliability in practical applications, a series of tests and evaluations are required.

Stability testing is an important means to evaluate the long-term performance and reliability of photovoltaic modules. As a key equipment for stability testing, the Photostability Chamber can simulate the performance changes of photovoltaic modules under different environmental conditions. By exposing photovoltaic modules to different lighting conditions for a certain period of time in the Photostability Chamber, its light decay characteristics, stability of photoelectric conversion efficiency, and durability can be evaluated.

IEC and BBA standards

The International Electrotechnical Commission (IEC) is an authoritative international organization that formulates electrical, electronic and related technical standards. IEC has developed a series of standards for the performance and reliability of photovoltaic modules, including light decay testing. These standards ensure the performance consistency and reliability of photovoltaic modules under different environmental conditions, and provide technical support and guarantee for the development of the photovoltaic industry. BBA is the abbreviation of Bundesverband Solarwirtschaft e.V., an organization representing the German solar industry. Both standards put forward specific requirements and specifications for the optical performance, temperature performance, testing methods, etc. of photovoltaic module photostability chamber. The Photostability Chamber from Millennial Solar meets the stability test specified in the MQT09 and MQT19 provisions of the IEC61215 standard. The light spot area reaches 1200*1000mm, and the spectrum meets the BBA standard.
