Abstract

Installing photovoltaic (PV) systems in dense urban buildings with limited space cannot produce enough electricity to meet the building's needs and have low efficiency due to the shading effect of neighboring buildings and high ambient temperature. Developing a suitable PV installation scheme for the buildings poses a challenge for designing PV installations to increase electricity generation and promote renewable energy utilization. This paper develops a new hybrid building applied photovoltaic (BAPV) and building integrated photovoltaic (BIPV) design methodology to offer flexibility in increased installation space and enhanced PV performance. The optimal PV installation is determined based on the performance parameters, including yield energy (YE), yield factor (YF), yield reference (YR), performance ratio (PR), global incident irradiation on the collector plane, shading losses, and PV loss due to temperature. BAPV/BIPV installation models are created with building information modeling and analyzed using PVsyst software with the technical aspect. The comparative case studies compare the performance of BAPV/BIPV installations for urban building applications with c-Si PV technology. The simulation results show that the proposed hybrid scheme implemented with BAPV/BIPV installation can generate 54.29% and 74.98% more energy than those from BAPV-only and BIPV-only installation, respectively.
城市建筑混合光伏安装方案设计与分析
在人口密集、空间有限的城市建筑中安装光伏系统,不仅不能产生足够的电力满足建筑的需求,而且由于邻近建筑的遮阳作用和环境温度高,效率低。为建筑物制定合适的光伏装置方案,对设计光伏装置以增加发电量和促进可再生能源的利用提出了挑战。本文开发了一种新的混合建筑应用光伏(BAPV)和建筑集成光伏(BIPV)设计方法,以提供灵活性,增加安装空间和提高光伏性能。根据性能参数,包括产能(YE)、产率因子(YF)、产率参考(YR)、性能比(PR)、集热器面整体入射辐照、遮阳损失和温度造成的PV损耗,确定最佳PV安装方案。BAPV/BIPV安装模型采用建筑信息建模的方法建立,技术方面采用PVsyst软件进行分析。比较案例研究比较了用于城市建筑应用的BAPV/BIPV装置与c-Si光伏技术的性能。仿真结果表明,采用BAPV/BIPV的混合方案比只安装BAPV和只安装BIPV的方案分别多产生54.29%和74.98%的能量。
