光伏组件表面积灰对发电性能的影响

Effects of Airborne Dust Deposition on PV Module Surface on Its Power Generation Performance

灰尘颗粒沉积到光伏组件表面后,会使组件前盖玻璃的透光率降低,导致组件的输出功率降低。介绍了用MATLAB/SIMULINK模拟灰尘沉积对光伏组件输出性能的影响,从不同灰尘沉积情况下光伏组件的输出特性曲线可以看出,灰尘沉积的增多,其最大功率点功率下降明显。在理论研究的基础上,搭建实验平台进行实验研究,结果证明仿真结果是有效可信的。

Airborne dust particles deposited on the surface of photovohaic （PV） modules will reduce the solar trans- mittance of the front cover glass, resulting in lower power output of PV modules. In this paper, MATLAB/SIMULINK was used to simulate the effects of dust deposition on the output performance of PV modules. As indicated from the PV module output characteristic curves in the different state of dust deposition, the maximum power point power of the module decrease significantly with dust deposition increasing. On the basis of theoretical studies, the test platform for experiment research is set up and the results show that the simulation result is effective and credible.
