摘要

Bifacial silicon Photovoltaic (PV) technology has the advantage of generating more energy output as compared with the conventional mono-facial technology. In this paper, a comparison is made between the performances of two bifacial silicon heterojunction modules mounted at two configurations under Qatar's climatic conditions: a tilt angle of 22 degrees facing south and a tilt angle of 90 degrees (vertical) facing east-west. The bifacial module mounted under standard tilt showed a 14% higher energy yield over the vertically tilted bifacial module. This is mainly due to higher irradiance received by the 22 degrees tilted module relative to the vertically tilted module. On the other hand, a thermal model has been developed using COMSOL Multiphysics to calculate the theoretical power output, energy yield and module temperature. A gain in the short circuit current is found to increase linearly with the ratio of the diffuse irradiance to plane of array irradiance. (C) 2018 Elsevier Ltd. All rights reserved.
