“…Introduction. Bifacial solar cells (SEs) have emerged as a result of the search for methods for the most efficient use of a valuable semiconductor layer that absorbs solar radiation for power generation [1][2][3][4]. Their advantage is the additional irradiation of the absorber from the back of the SE, which is not carried out in conventional one-acial devices.…”

“…Existing models for determining the energy performance of solar elements are based on the idea of one-facial frontal irradiation of the device. However, the back side, perceiving the radiant energy, has a corresponding effect on the overall energy balance [3,4]. Among the various factors influencing the radiation, from the point of view of operating mode control, the geometric, i.e.…”

“…For the back side, in [4] studies of the effect of reflectivity of different surfaces were conducted. In [3], a dynamic three-layer model of the solar element is proposed, which includes the radiation component of the interaction with the back side. The results showed an increase in temperature in the bifacial panels, taking into account the radiation.…”

Purpose. To develop the integrated mathematical model for definition of bifacial solar element rational power operation in the various operation conditions caused by orientation of solar panels and power influence. Methodology. We have proposed the method of definition of bifacial solar elements irradiation and temperature mode and also electric power production at various orientation of panels. Results. We have made analytical investigations of temperature operation conditions of solar elements and their influence on electrical power for various panels orientation in space. Features of irradiation of the forward and back parts of solar panels, conditions of a temperature operating mode and its influence on electric power production are shown. Possibilities of rational conditions of spatial panels orientation are considered. Originality. We have suggested and proved the model of definition bifacial irradiation solar panels and thermal conditions of electric power production and also rational conditions of spatial orientation of panels. Practical value. The developed by us methodology as well as results of its application, allows to choose rational architecture of a solar power station with high efficiency.

The current industrial scenario highlights the increased attention being awarded to bifacial photovoltaics (PV) technology due to its property of flux absorption from the rear side. But akin to monofacial modules, bifacial modules are also subjected to shading scenarios due to non-uniform illumination.A case study for comparative analysis on performance of bifacial and monofacial PV system is presented for Jaipur, India, which falls in the composite zone of Indian climate. An attempt has been made to quantify the performance of bifacial PV module under various shading scenarios and compared with monofacial module under similar condition. The work is done using a threephase approach, wherein initially the performance is studied at a module level and simulations performed to generate voltage profiles of individual cells under shade. This is followed by determining optimum inter-row spacing through experiment and RADIANCE simulations in an attempt to mitigate unwanted shade due to adjacent rows in an array. Finally, a dynamic approach to reconfigure the array under shade, combining electrical and physical reconfiguration methods to mitigate shading is studied. Based on the results of the study, bifacial technology always emerges as the superior in terms of power output over conventional monofacial technology for a wide range of partial shading scenarios. Combined physical and electrical array reconfiguration for a 3 Â 3 array shows fill factor reduction can be limited to 18.9% compared to non-uniform shade reduction of over 40%.
