Photovoltaic module test chamber/photovoltaic module frost freeze cycle test chamber is an essential test equipment mainly used in photovoltaic industry and solar energy industry. It is used to test photovoltaic modules, mainly monocrystalline silicon modules, and crystalline silicon photovoltaic modules for ground use. A series of photovoltaic modules, such as thin film photovoltaic modules, are subjected to parameters such as high temperature, low temperature, alternating humidity, or changes in the temperature of a constant test, and the parameters and performance of the constant temperature and humidity changes in the temperature environment. Apply to schools, factories, military, research positions, and other units.
