光照入射角对光伏电池板功率的影响

Influence of Incident Angle of Light on Power of Photovoltaic Panels

主要研究在一定光照强度下,不同光照入射角度对地面光伏电池板实际输出功率的影响。通过智慧新能源实训设备对4块平行分布的单晶硅光伏板进行不同角度入射光测试,采用PLC控制设备灯杆的运动情况,使用力控组态软件对PLC进行控制,并对数据进行读取,从而得到光伏电池板实际输出功率随光照入射角度的变化关系。实验表明:在入射角范围为0°~90°时,随着光照入射角度的增大,光伏电池板实际输出功率也逐渐增大;在角度较小时,功率随光照入射角度的增长速率较为平稳,在接近90°时,功率随光照入射角度的增长速率加快。

The paper mainly studies the effect of different incident angles of light on the actual output power of ground photovoltaic panels under a certain illumination intensity.Four parallel distributed monocrystalline silicon photovoltaic panels were tested with the practical training equipment of smart new energy for incident light at different angles.PLC is used to control the movement of the lamp post.The force control configuration software controls the PLC and reads the data.Thus,the relationship between the actual output power of photovoltaic panels and the incidence Angle of light is obtained.The experiment shows that when the incidence Angle ranges from 0°to 90°,the actual output power of the photovoltaic panel increases with the increase of the incidence angle of light.When the Angle is small,the growth rate of power with the incidence angle of light is relatively stable.When the Angle is close to 90°,the growth rate of power with the incidence angle of light is accelerated.
