“…Unavailability of high-class apparatus to experimentally evaluate the electrical performance of any PV module presents a hurdle when the output is to be measured under controlled levels of irradiance and module temperature. To determine the maximum power available from a PV module at conditions other than the STC, an alternate approach has been provided in IEC 60891, [38][39][40] procedures one to three. These procedures allow for the calculations of corrections in voltage and current in accordance with the operating conditions.…”

The idiosyncrasy of bifacial photovoltaic devices by means of its ambivalent nature in absorbing irradiation demarcates this technology from conventional monofacial modules. The performance of bifacial PV devices is primarily a function of the orientation of the device, that is, its tilt angle (β), the elevation of the module above the ground (E), the albedo of the location (ρ g ) and the azimuth angle (γ). The current work, focusing on determining the optimum setting for module installation, takes into consideration three factors, namely, β , E(m) and γ , concentrated on maximizing the power generation from the test bifacial PV module at Jaipur, India (26.91 N, 75.78 E) using full factorial design experiment through Taguchi method. Based on Taguchi analysis, the optimal parameter setting for maximizing response obtained is β = 40 , E = 0.8 m and γ = 22.5 . Adequacy of the design was determined through ANOVA, which presented a high R 2 value of 88.7%. The results for optimal parameter setting obtained using Taguchi design are validated through experiment, and the error in computed value and experimentally determined value of response is 2.64%. The PR of the module installed at optimum orientation, upon investigation, was highest among test orientations (84.76%) due to greater rear side irradiance collection. Further results show that increasing albedo increases the output for modules installed at optimum orientation. The results are also verified against empirical relations presented in the literature to highlight the competency of the results.

In the present simulation work with experimental validation, the performance of a transparent conductive oxide (TCO) film‐coated spectrally selective reflector in the low‐concentrated photovoltaic application has been analysed. The use of mirrors in solar photovoltaic (PV) applications is a well‐established thing. However, it increases the operating temperature and requires more thermally stable, expensive solar modules. In this regard, for the first time, commercially available TCO‐coated glasses such as fluorine‐doped tin oxide (FTO) and indium tin oxide (ITO) have been integrated with mirrors. The spectrally selective reflector is a promising technology to achieve a high‐power yield from the commercially available crystalline silicon photovoltaic (C‐Si PV) module during its lifetime. They have the property to absorb unwanted photons in the region of the AM1.5 spectrum (1200 to 2000 nm), which partially thermalises the solar module through plasmonic absorption. The present study found that the proposed approach helps to restrict the increase in PV module temperature caused by the reflected rays from a mirror. The electrical performance of a standalone C‐Si PV was compared with that of the same system after the addition of FTO, ITO and a conventional mirror system. Our analysis indicates that, with the mirror integration, the degradation rate can increase to 1.5% per year if the standalone PV module's ageing rate is 0.8% per year. Through FTO incorporation with the same, the ageing rate has been reduced by up to 1.18% per year due to a reduction in temperature. This result is quite interesting, considering that spectrally selective reflectors do not stop high‐energy photons from thermalizing the PV module. The entire work has been done on commercially available materials, which makes it easier and ready to be implemented in large PV plants. Highlights A spectrally selective mirror for PV power boosting. Transparent conductive oxide (TCO) glass integration with mirror reduces the IR concentration approximately 50%. The reduction in thermalisation of PV module from the mirror by 3–5°C. This integration increases the PV module operational life by at least 4 years compared with commercial mirror.

“…The bifacial solar modules were more expensive (10.05%) than the monofacial solar modules in terms of unit construction cost. The lifespan of the subject APV system is expected to be 25 years, which is widely adopted or assumed in the solar power industry and in studies [19][20][21][22]. 1 The cost includes a building permit fee and a fee for linkage to an existing electric distribution system.…”

“…If we consider electricity generation per unit under these three cases, the quantity of electricity generated by the monofacial solar modules was 9.77% lower than that by the bifacial solar modules. 1 The value was estimated assuming a 25-year lifespan and efficiency degradation of a solar module [21,22].…”

The aim of this study was to identify an efficient agrophotovoltaic (APV) system structure for generating electricity from solar radiation without causing an adverse impact on crop growth. In a temperate climate region, it is critical to design an APV system with appropriate structure with the maximum amount of electricity generation because, unlike in desert areas, strong solar radiation is only available for a few hours a day. In this study, APV systems with three different shading ratios (i.e., 32%, 25.6%, and 21.3%) were considered, and the optimum structure in terms of electricity efficiency and profitability was investigated via nonlinear programming. Moreover, an estimation model of electricity generation was developed via a polynomial regression model based on remote sensing data given by the APV system located at Jeollanamdo Agricultural Research and Extension Services in South Korea. To evaluate the impact of the APV on crop production, five different grain crops—sesame (Sesamum indicum), mung bean (Vigna radiata), red bean (Vigna angularis), corn (Zea mays), and soybean (Glycine max)—were cultivated in the system. As a result, the proposed optimization model successfully identified the best APV system structure without reducing existing crop production.
