QuickSun 550Ei is a versatile testing system for qualifying of PV modules with dimensions up to 105 x 205 cm2. Basic set up includes a top class solar simulator which measures modules in sunny side up position enabling e.g. soiling simulations. Several additional measurement methods can be integrated to the same system including high resolution EL imaging with analysis software from one of the most recognized EL system suppliers. Several additional measurement methods can be integrated to the same system including high resolution EL imaging, bypass diode functionality test, temperature coefficient measurement, and true nA scale leakage current measurement.
Actual leakage current of PV modules is a few hundred nano amperes with a typical 4 KV test voltage while the widely applied dielectric withstand test acceptance criteria is 50 μA. QuickSun 550Ei surpasses this minimum requirement and measures true insulation resistance and leakage currents accurately with sensitive enough instruments. This enables run time diagnosis of both contacting reliability and real module leakage characteristics.
