Photovoltaic Module Environmental Testing

Solar power generation is becoming increasingly popular and is an important way for countries around the world to achieve energy transformation. However, photovoltaic modules do not perform well in all scenarios. Therefore, environmental testing is crucial to ensure that photovoltaic power generation systems achieve expected benefits. Environmental testing of PV modules can reduce the chance of adverse results and minimize surprises.
Zhongke Testing Reliability Experiment Center has environmental testing capabilities for various photovoltaic modules and provides professional environmental testing services for photovoltaic modules.

1. User solar power supply: such as 3-5KW household rooftop grid-connected power generation system;
2. Transportation field: such as navigation beacon lights, traffic/railway signal lights, traffic warning/sign lights, Yuxiang street lights, high-altitude obstacle lights, etc.;
3. Communications/communications field: such as solar unattended microwave relay stations, optical cable maintenance stations, broadcasting/communications/paging power systems, etc.
4. Petroleum, ocean, and meteorological fields: such as oil drilling platform life and emergency power supply, ocean detection equipment, meteorological/hydrological observation equipment, etc.
5. Power supply for household lighting: such as garden lights, street lights, portable lights, camping lights, climbing lights, fishing lights, black lights, etc.
6. Photovoltaic power station: 10KW-5OMW single photovoltaic power station, landscape (diesel) complementary power station, various large parking lot charging stations, etc.

1. Cycle test: damp heat (DH)/ultraviolet (UV)/thermal cycle test, light-moisture-heat comprehensive cycle test
2. Mechanical load test: static and dynamic
3. Special application environment tests: sand and dust test, salt spray test, ammonia corrosion test
