摘要
为进一步提高太阳能光伏板转换效率,设计一种节能高效的太阳能追日系统。系统结合太阳光强检测和太阳轨迹计算追日的各自优势,采用太阳轨迹法对追日系统进行粗调,采用太阳光强变化检测法对系统进行细调。利用直流电机和减速器的配合,控制太阳能板在东西方位上实现追日;利用由直流电机做驱动力的电动推杆控制太阳板在南北高度上实现追日。测试数据表明,系统提高了太阳能光伏板的转换效率,节能达30%以上。
ABSTRACT:In order to further improve the conversion efifciency of solar photovoltaic panels, design an energy-efifcient solar tracker. System combined with sun light intensity detection and the sun trajectory calculation zhuiri respective advantage, the solar trajectory method of tracker for the coarse by sun light intensity change detection method to ifne tune the system. Use DC motor and reducer with and control the solar panel in the east-west direction realize zhuiri;use by a DC motor driven electric putter control solar panels at the height of the north and south implementation of chasing the sun. Test data show that the system can improve the conversion efifciency of solar photovoltaic panels, energy saving is more than 30%.
