Temperature cycling test

              Solar power has been regarded as the trend of renewable energy sources

          ever since the pressing energy saving demands. A sound solar cell design

          can effectively absorb light emitted by the Sun to produce voltage and current.

          An assessment of solar cells’ capabilities must include operational life cycle

          testing and outdoor tolerance to normal environments.

          IEC61215, IEC61646 and UL1703 are test regulations for the characteristics

          of solar cell modules to ensure the materials can sustain severe

          outdoor environments and to minimize the chances of damage.

          UL1703-35 Temperature cycling test and the thermal cycling

          TC200 of IEC61215 or IEC61646 are designed to test solar

          cells for 200 temperature cycles to monitor the continuity of the

          electric circuit; and to identify problems of malfunction,

          leakage of electricity, open circuit and insulation occurring

          at internal or welding spots that are caused by different

          thermal expansion coefficients of various packing materials.

      

     Temperature cycling test:

          Temperature cycling test requires temperature control and a

          working voltage to ensure electric flow in modules. A constant temperature

          and constant humidity chamber (CT/CH chamber) and a programmable power

          supply are used to control the solar panel’s temperature variation and to supply

          power to solar modules in order to verify whether solar modules meet the

          regulations under temperature cycling. Solar modules require different test voltage

          due to different connection method of modules. Therefore, the output conditions

          of the power supply must be set according to the actual specifications of the solar
           modules. 

          The GW Instek PSW Series of power supplies are very useful for this.
