摘要

目前，光伏(PV)电池的转换效率相当低，一般在20%以下。此外，光伏发电系统的发电量深受一些外部因素的影响，其中最显著的是太阳辐射强度和环境温度。在本文中，将分析太阳的运动影响，因为太阳全年的位置显著影响光伏系统的输出。实验分析将在罗马尼亚雅西“乔治·阿萨奇”技术大学高效与可持续能源研究平台(ENERED)的小型光伏系统模型上进行，以评估雅西市特定地理坐标下的最佳光伏模块倾角。

Experimental Evaluation of the Optimum Tilt Angle for Fixed Photovoltaic Modules

Nowadays photovoltaic (PV) cells have a rather small conversion efficiency, generally under 20 percent for the commercial units. Further on, the amount of electricity produced by a photovoltaic system is deeply influenced by some external factors, the most significant being the solar radiation intensity and the ambient temperature. In this paper an analysis of the motion of the sun influence will be presented, as the sun’s position throughout the year significantly affects the output of PV systems. Experimental analysis will be conducted on a small-scale PV system model within the Efficient and Sustainable Energy Research Platform (ENERED) research platform of the “Gheorghe Asachi” Technical University of Iasi, Romania, in order to evaluate the optimum PV module tilt angle for city of Iasi specific geographic coordinates.
