Development of an Automated Measurement System for Checking Irradiation Non-uniformity of Solar Simulators
Advances in Technology Innovation
Generally, for some solar simulator manufactures, the measurement of irradiation non-uniformity is made by placing a PV cell artificially and point by point on each measuring point on the solar module. It records each corresponding output voltage of PV cell. It is time-consuming and easy to produce measurement error. If either an XY table or a multi-axis robot is applied in this case, it is ot only expensive but also difficult to carry and setup. Hence, an innovative and automated measurement
... mated measurement system, which consists of both a self-developed smart robot and a monitoring and control system, is proposed in this paper to solve aforementioned problems. The monitoring and control system, i.e., constructed by a PC and a self-developed LabVIEW-based application program, plays the role of remotely commanding the operation mode of a robot, receiving the irradiance data being transmitted from the robot and calculating the irradiation non-uniformity. Once the irradiation non-uniformity is calculated, some operations are made to adjust the irradiation parameters of the solar simulator such that the irradiation non-uniformity can meet the specification, i.e., 2%, 5%, 10% for class A, B or C of solar module, respectively.
