【摘要】 多镜面聚光是通过多块平面镜对太阳光进行反射,使其汇聚在特定区域内,从而提高该区域内太阳电池发电功率的一种方法。该方法具有增效明显、价格低廉、易于维护等特点,但是直线排布的平面镜聚光系统存在着相互遮挡导致聚光不均匀的问题,且占地面积庞大。因此本文提出了交错分布式的多镜面聚光方式,有效地解决了这些问题,并给出了在互不遮挡的情况下,平面镜及太阳电池间的相互位置及距离关系,计算出单个镜面的尺寸,充分利用了太阳电池,降低了光伏系统的太阳电池配置功率,从而降低系统成本,收效显著。更多还原

【Abstract】 The multi-mirror focusing is one of enhancing solar cell generated output method which reflects the sunlight to the solar cell through many plane mirrors.This method has characteristics of high efficiency,low price, design simplicity for easy maintenance and so on.But the straight line distributional plane-mirror focusing system not only exists the problem of focusing unevenly which is caused by intercepting mutually,but also occupies large area.Therefore this article proposed interlocked distributional multi-mirror condensation way,which can solve these problems effectively。Under no-interception condition,the relative position and distance between the plane mirrors and solar cell are given.And the plane mirror’s size question is also discussed in this article.The experiment results demonstrate that the solar cell can be used fully under interlocked distributional multi-mirror condensation way,which reduced the solar cell disposition power of the PV system.So the system cost can be reduced remarkably.更多还原
