Various test devices and inspection equipment have been developed to meet the test requirements for Cell and Module process in Solar Cell Testing. First, the I-V Tester measures the conversion efficiency of a cell by dividing it. Next, the Automatic Optical Inspector identifies the cell color and printing defects on the face and back and last a Solar Cell Sorter conducts the sorting.

Furthermore, the PV inverter has to control the current flow and calculate the back current besides converting DC to AC when the PV system is assembling. Chroma AC/DC power supply and electronic load can simulate and test the output electricity. An automatice test system model 8000 is provided to test the performance like maximum power point tracking (MPPT) and efficiency. Users also can use 8000 ATS to test standard UL1741 and IEEE 1547.1 to assure it's quality.
