摘  要:
太阳能自动跟踪可以显著提高太阳能电池单位面积的光电转换率。提出一种新型光电跟踪方式:采用16个光敏电阻组成的圆形阵列,利用遮挡杆的投影检测太阳光的位置,间歇式调整太阳能板角度,实施自动跟踪。试验结果证明,该跟踪系统相对固定角度摆放方式,提高光伏电池发电效率33.04%;相比实时跟踪系统,降低机械耗能50%以上。

摘  要:
Automatic solar tracking can significantly improve the photoelectric conversion rate of solar cells per unit area.We propose a new type of photo-electric tracking system.This system tracks the position of sun by using the projection of lever with a circular array consisted of 16 photosensitive resistance and implements automatic tracking by adjusting the angle of solar panels intermittently.The test results show that the tracking system can improve the power generation efficiency by 33.04% compared to the system with fixed angle,and can also reduce consumption of mechanical energy by more than 50% compared with real-time tracking system.
