太阳能光伏组件表面沙尘沉降规律研究

Study on the law of sand and dust deposition on the surface of solar photovoltaic modules

运用Fluent中混合模型对沙粒在光伏组件表面的沉降行为进行模拟计算。分析了不同的风速以及安装倾角时,光伏组件表面沉降规律的变化情况。研究结果表明:风速越大、安装倾角越大,沙尘在组件表面的沉降分层明显;通过公式计算组件表面的沉降量,知道风速不变时,安装倾角的角度越大,沙尘在组件表面的沉降量也越大;安装倾角不变时,当风速越大,沙尘的沉降量却越小,说明安装倾角以及风速是影响光伏组件表面沙尘沉降的两个重要因素。

The sedimentation behavior of sand particles on the surface of photovoltaic modules was simulated byFluent mixed model. The changes of surface settlement behavior of photovoltaic modules under different wind speeds and installation inclination angles were analyzed. The results show that the larger the wind speed and thelarger the installation inclination angle, the more obvious the settlement of sand dust on the surface of the component; the settlement of the surface of the component is calculated by the formula, and it is found that the installation angle is larger when the wind speed is constant, and the sedimentation amount of sand dust is larger. When the installation inclination angle is constant, the wind speed is larger, and the settlement of the component surface is smaller, indicating that the installation inclination angle and the wind speed are two important factors affecting the dust deposition on the surface of the photovoltaic module.
