Grid-connected amorphous silicon photovoltaic array

Abstract

A roof‐mounted photovoltaic (PV) array has been installed at Loughborough University in the UK. The array output is connected through a commercial grid‐connected inverter to the University supply network. The system was the third grid‐connected PV inst allation to be connected and generating in the UK. It is the first and only grid‐connected system using amorphous silicon thin‐film PV modules in the UK. The system is fully instrumented to support the research and development that CREST is conducting on grid‐connected PV systems, including: inverters; thin‐film amorphous silicon and the effects of shading on performance. The paper presented here describes the design, installation and commissioning of the system. Data from the first year of operation along with the results of a preliminary performance analysis are presented and discussed.

Performance analyzes of different photovoltaic module technologies under İzmit, Kocaeli climatic conditions

“…[4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. According to the study conducted by Simmons et al, performance of a-Si module was monitored for a year and it was shown that early performance degradation occurs in case of a-Si usage in PPS [4]. Akhmad et al studied the performance comparison of a-Si and pc-Si modules by using data obtained in two years.…”

Color filter effects on the performance of monocrystalline and polycrystalline photovoltaic solar panels

“…In literature, there are many studies related to solar energy and a lot of studies presents that energy efficiency of photovoltaic panels based on material type, solar irradiation, temperature coefficient etc. [6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Overall electrical power generation using a-Si, polycrystalline and monocrystalline panels was doi: 10.31593/ijeat.1201422 investigated focusing on outdoor performance [20].…”
