The objects of the study are solar modules. The world has witnessed a change in all aspects of life, especially in the last period, when the world witnessed an increase in the demand for energy and all regions. Here the imperfection appeared in meeting the energy needs, just as the traditional sources (oil, coal, and natural gas), for example, are no longer hope as they are non-renewable sources. In addition to these sources, to exploit the energy in them, we must burn, which pollutes the environment, in addition to the cost of transportation. Not long ago, solar energy began to produce electricity through photovoltaic modules, and competition began to make photovoltaic modules with higher efficiency. The main aim of this study is to clarify the concept of bifacial photovoltaic modules and show some differences between them and monofacial photovoltaic modules. The current report consists of the definition of bifacial photovoltaic modules and their most important specifications, comparing them with monofacial photovoltaic modules, which are the best, the factors affecting their energy production, and the type of radiation used in each type. In fact, the utilization of albedo radiation for monofacial photovoltaic modules does not exceed 2 %, while this percentage is exceeded in bifacial photovoltaic modules. So, it can be recommended here that the trend to use bifacial photovoltaic modules can be economical and space-saving space because it produces more amount of electricity for the same unit area, which in turn this spaces it available for other applications, and also, increase the amount of electricity due to the increase in the effective side size (two sides: one upwards and the other is downward) of the solar modules.
