The Outdoor Multi-Channel PV Module Aging Test System is a high-throughput photovoltaic testing platform designed for long-term outdoor performance monitoring and reliability evaluation of solar modules. The system is especially suitable for emerging photovoltaic technologies such as perovskite solar cells, tandem solar cells, and thin-film photovoltaic modules, where real outdoor validation is critical for product development and stability assessment.
The system integrates a multi-channel electrical testing unit, relay switching system, environmental monitoring modules, data acquisition hardware, and intelligent control software into one complete outdoor testing solution. By enabling multiple photovoltaic samples to be tested simultaneously under real sunlight conditions, the system greatly improves testing efficiency while ensuring high data consistency and repeatability.
Unlike conventional laboratory testing platforms that rely only on solar simulators, this system operates directly in natural outdoor environments. It continuously monitors the real power generation performance of photovoltaic devices while recording environmental conditions such as temperature, humidity, and solar irradiance, allowing researchers to correlate device performance with real environmental stress factors.
The system adopts a dual architecture consisting of an outdoor test cabinet and an indoor monitoring workstation. This structure allows operators to conduct long-term stability tests in outdoor conditions while remotely monitoring test progress, reviewing data, and managing system operations from an indoor computer.
The system adopts a high-efficiency multi-channel testing architecture that supports simultaneous testing of multiple photovoltaic modules. In the standard configuration, the system provides 8 independent test channels, and each channel supports 8-point relay scanning, allowing a large number of samples to be monitored in a single experiment.
This design significantly increases testing throughput and shortens experimental cycles, making the system ideal for photovoltaic material screening, module comparison, and reliability studies.
