In this article, we measured and estimated the outputs of car-mounted PV panels under actual driving conditions and different effective shading angles. On a sunny day, the performance ratio (PR) decreased to 0.99, despite the decrease in module temperature caused by the increased wind speed when driving. The PR decreased because of the effect of partial shading over the PV module. Public infrastructure could have led to dynamic partial shading passing across the PV module at high speeds. Furthermore, the effective shading angle being close to the sun's altitude could also have led to static partial shading. In contrast, on an overcast day the PR value was almost the same (>1) under both driving and parking conditions; this was because of the low module temperature and the spectrum effect.

评估车载光伏模块在行驶条件下的输出


在本文中，我们测量并估算了车载光伏板在实际驾驶条件和不同有效遮阳角度下的输出。在晴天，尽管行驶时风速增加导致组件温度下降，但性能比（PR）仍下降至0.99。由于光伏组件部分遮蔽的影响，PR 下降。公共基础设施可能会导致动态局部阴影高速穿过光伏组件。此外，接近太阳高度的有效遮阳角度也可能导致静态部分遮阳。相比之下，阴天行驶和停车条件下的 PR 值几乎相同 (>1)；这是由于模块温度低和光谱效应造成的。
