| CPV (Concentrator photovoltaic) requires accuracy in optical alignment. Optical misalignment in the module was measured and analyzed. Such information was useful to identify assembly problems and improved module performance. 1-D and 2-D Monte Carlo simulations were developed to analyze the impact of alignment errors by assembly errors. The 1-D simulation was useful to anticipate the power output of the module, whereas 2-D was for acceptance angle. The 2-D model showed that the gap from Pmp-based acceptance angle (Pmp: Power at the maximum power point) from that of Isc-based (Isc: Short-circuit current) was a function of deviation of assembles misalignment in the module. The rough rule for the acceptable assembles misalignment is that the standard deviation of the assemble misalignment will be less than 10% of acceptance angle of the optics, whereas that of power output of the single module is 20%. This fact implies that the inspection of the acceptance angle is highly recommended in the CPV module production. | |
