摘要
为了提高太阳能电池的转换效率,设计了一种以Msp430F149单片机为核心,基于双轴的太阳能自动跟踪装置。该装置能精确跟踪太阳运动轨迹,使太阳能电池组件在晴天时始终垂直接收太阳光;在阴天时自动切换至时钟式跟踪,其转换效率高、成本低。实验结果表明,对比固定安装的太阳能电池板,在相同条件下,采用太阳能自动跟踪装置的太阳能电池板的接收率提高了约40%。
A novel automatic dual-axis tracking solar energy device with the core of Msp430F149 is designed to improve conversion efficiency of the solar panel.The solar energy device can make solar panel always vertical to the sunlight at sunny day.Otherwise,the clock model will be used.The device is of high conversion efficiency and low cost.The experiment indicates that compared with the device that the solar panel is fixed,the new device can improve the efficiency by 40%in a day under the same condition.
