“…The first step is to determine the effective area of the module as the panels were designed with dimensions stated in Table 1 which includes the frame, EVA lamination, busbars, junction box and conductors. The packing density thus can be defined as the area of the panel covered with cells over the area with no cells as in Equation (2).…”

“…The global energy demand is expected to increase by 25% until 2040 which will push the energy sector [1]. In 2020 alone, Solar Photovoltaics (PV) accounted for 3.1% of the total global electricity generation with annual solar PV generation level of 820 TWh and a PV capacity deployment of 134 GW which is expected to increase to 630 GW per year until 2030 [2]. The exponential growth in the installations of photovoltaic systems is the consequence of limited supply of fossil fuels, environmental concerns, scalability, and the continuous decrease in costs [3].…”

The technology behind Bifacial Photovoltaic systems has existed for a long time but only recently gained popularity due to the increased surface area for the absorption of solar radiation by the rear-side of the bifacial Photovoltaic (PV) panel. The bifacial gain and output energy yield (kWh) is affected negatively by self-shading leading to non-uniformity in the absorbed irradiance. The purpose of this research is to simulate and investigate the effect of varying parameters including the elevation of a bifacial PV module from 0.5 m to 1.0 m with a step size of 0.1 m and its effect on the absorbed irradiance and subsequent output energy yield (kWh). Uniaxial solar tracking combined with varying the elevation is implemented by positioning the bifacial PV system in an East-West orientation with an azimuth angle of +90° (facing East); this follows the sun’s hourly elevation angle and path throughout the day. Three albedo of values 0.2 which represents grass, 0.6 which represents fresh white concrete and an ideal albedo of 0.99 is combined with the variation in elevation of the bifacial PV module and is further analysed and compared with a monofacial PV module. Simulation results from TracePro show that East-West tracking reduces the Incident angle closer to 0° which results in higher Flux (W) collected by the surface, except for time intervals at 8:00:00 AM and 18:00:00 PM where the sun is located furthest away from the model. The energy yield (kWh) of the bifacial PV panel first increases sharply from an elevation of 0.5 m to 0.8 m where a peak value of 4748.8 kWh is observed, followed by a drop in energy yield (kWh) at 0.9 m and saturation at 1.0 m; hence the elevation parameter of 0.8 m is determined to be the point of inflection. The BGE at 1 m has a significant value of 0.302 which translates to 30.2% in bifacial gain. The largest difference in energy yield (kWh) is observed to be 1114.55 kWh (30.67% increase) at 0.8 m; the bifacial PV module greatly outperforms the monofacial PV module at this elevation in the uniaxial solar tracking system and is determined to be the optimal value.

Exergy analysis is a branch of thermodynamics receiving an increasing interest in the scientific literature and in didactic presentations. Exergy represents the maximum useful work obtainable by a system that can interact with a reference environment. There exist two exergy functions: exergy, that refers to a collection of matter contained within the reference environment; flow exergy, that refers to a collection of matter flowing in a pipe, that can interact with the environment and diffuse into it. The usual derivations of the expressions of exergy and flow exergy are either complicated or not general. Moreover, two separate derivations are necessary, due to the different conceptual schemes employed in the definitions of these properties. As a consequence, the expressions of exergy and flow exergy are often reported without a derivation in didactic treatises. In this paper, we provide a simple and general unified deduction of the expressions of exergy and flow exergy. Moreover, we show that the logical scheme proposed, based on the concept of useful energy of a system contained in a pressure field, allows a simpler deduction and a deeper interpretation of the energy balance equation for a control volume in steady state. Finally, in order to complete the didactic treatment, we rewrite the expression of the molar exergy of a pure substance at ambient temperature and pressure in a form applicable to reactive substances, and we present an application of this form.

A novel wider field of view of concentrators, which is composed of an optical fisheye lens with wider field of view and a traditional compound parabolic concentrator (CPC), is proposed in this paper. In this novel concentrator, exits of rays of meniscus fisheye lens and entrances of rays of CPC is fitted tightly on the basis of principles of ray trace, so that the proposed concentrator can be used to concentrate higher optical power than traditional CPC. In this paper, based on the geometry construction model of the new wide-field concentrator is established, the optics simulation software of TracePro is employed to model and design the structure of the concentrator, and analyses of performances for the concentrator is also carried out. The results show that this new wide-field concentrator can significantly increase the light energy received by the concentrator compared with a conventional concentrator without a wide-field fisheye lens, and can significantly improve the performance of LED wireless optical communication systems if used in the receiving optical antenna of LED wireless optical communication systems.
