QuickSun 550Ei

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. Also hot spot revealing IR images can be recorded by applying either forward or reverse bias current, and true nA scale leakage current measurements can be performed with sensitive enough instruments.

A detailed test report is included with every simulator proving Class A+A+A+ performance with respect to spectrum, irradiance non-uniformity and short term instability (STI). Long term instability (LTI) is also within Class A+ tolerances during the 40 ms long flash pulse. A feedback controlled electronic load and sampling unit measures voltage, current and irradiance signals when module is swept e.g. from short circuit to open circuit. Both forward and/or backward voltage sweeps including their slope rate can be adjusted freely and also a combined IV graph is calculated automatically. This enables accurate measurement of very high capacitance and top efficiency c-Si modules. Applied test procedures and reports comply fully with the standards IEC 60904-1 and IEC 60904-9 as inspected and proved by SGS Fimko Ltd.
