Main Parameters Analysis of the Solar Street Lamp in Campus

The mathematical model to determine the main parameters of the solar street lamp has been built. The structure and the main parameters of the solar street lamp were analyzed in the paper. The yearly average optimal tilted angle for the solar cell module used in Qujing is approximately 23.75o. For a 60 W high brightness DC LED lamp, the area of the solar cell and the battery capacity to meet the energy consumption of the solar street lamp are 3.67 m2 and 2.89 MJ, respectively.
