【 摘 要 】

In this study, simulated annealing (SA) algorithm was used to optimize the installing angles, specifically the tilt angle and surface azimuth angle, to maximize the solar radiation on photovoltaic (PV) panels in Wuhan, China. The KT model was adopted to calculate the monthly average solar radiation on the tilt PV panels and the SA algorithm was chosen to do the optimization. The optimized installing angles obtained by the KT method was compared with those obtained by the experimental solar radiation information, and the results agreed quite well. It is found that the summer in Wuhan has the largest monthly solar radiation. The optimized tilt angle varies in different months but the optimized surface azimuth angle is approximate 0 degree. It is implied that the tilt angle is the key parameter in the PV installation rather than the azimuth angle. For the yearly total solar radiation, the optimized tilt angle is 15°, which is about 15.52° less than the latitude.
