In photovoltaic test solutions, various test devices and inspection equipment have been developed to meet the test requirements for solar wafer/cell test. The I-V tester measures the conversion efficiency of a cell by dividing it when the automatic optical inspectors identify the wafer or cell's color and printing defects for both sides, finally, pick and place handlers conduct the sorting.
A PV system is an energy system which directly converts energy from the sunlight into electricity. Once light hits the solar cell (array), electricity is generated and the DC is collected at a PV inverter.
PV inverter is a device that changes DC power to AC power and is also a key component in PV systems. There are two main types of PV systems, Grid Connected or Off Grid. Grid connected systems are usually installed on a building and provide electricity directly into the mains supply. Off grid systems are usually used where power is required but access to a mains supply is unavailable. Chroma provides PV inverter testing solutions based on its thirty years of experience in power electronics testing.
