本发明提供一种太阳能追日面板， 特别是关于一种控制该太阳能面板摆动至面 板整体接受太阳光照射的倾角的自动补偿方法， 并涉及实施该方法的驱动单元、 光 传感器及控制单元。 背景技术
传统可自动跟随太阳光照射角度摆动的追日型太阳能面板， 可见揭露于中国台 湾省公告第 M317554 号专利案中， 主要是将太阳能面板装设于一可摆动的承架顶 部， 且承架近側装设有一驱动单元， 经由一控制单元依据季节及时间判断太阳光照 射角度， 以驱动太阳能面板随承架摆动， 促使太阳能面板的受光端面能取得太阳光 的最佳照射角度。
此外， 上述传统的追日型太阳能面板， 一般除了釆用单一组太阳能面板独自进 行发电外， 在中国台湾省公告第 M379172号专利案中， 也揭露有一种可采用多组相 邻配置的太阳能电池同时发电的技术， 主要是经由一连动杆枢接各太阳能电池， 以 同步驱动所述太阳能电池朝追日方向摆动。
且知， 在上述配置多太阳能面板同时进行发电的情况下， 实际上都是将多太阳 能面板串接成单一串联电路， 且组成该太阳能面板的多太阳能电池之间也是以串联 方式连接成单一电路； 因此， 当所述太阳能面板的受光端面整体都受到太阳光照射 时， 所述太阳能电池可各自发电而使该串联电路导通， 藉以对外输出电力。
然而， 当多太阳能面板同步朝追日方向摆动， 且各太阳能面板摆动翘起的端部 恰好遮蔽太阳光照射相邻太阳能面板摆动荡落的端部时， 会在该太阳能面板荡落端 部的受光端面上形成一阴影区， 而使该阴影区所属的太阳能电池停止发电， 造成该 串联电路呈断路状态， 导致所述太阳能面板暂时停止发电， 必需等到多太阳能面板 摆动至其受光端面整体受到太阳光照射时， 才能重新激活并进行发电。
