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.

“…Soiling on bifacial PV systems is a complex problem and requires an in-depth investigation of installation parameters: such as tilt angle, mounting height, and rear/front side dust deposition rates [127][128][129][130][131][132][133][134][135][136][137][138]. Vertical bifacial modules show great potential for negative soiling which can be employed as noise-barriers, building integrated systems, and for peak shaving of the power profile using east-west orientation [127][128][129][130][131][132][133][134][135][136][137][138]. In principle, all PV systems (bifacial or monofacial), experience a soiling effect; however, the effect on bifacial PV is less pronounced.…”

“…This is primarily due to a smaller amount of dust exposure on the rear side of the module in tilted systems or due to the vertical installation practice of bifacial technology [138]. With the recent interest in bifacial PV installations, the impact of on energy yield and LCOE has become the prime focus of the solar-energy community for accelerating its deployment [40,[127][128][129][130][131][132][133][134][135][136][137][138].…”

A Comprehensive Review of a Decade of Field PV Soiling Assessment in QEERI’s Outdoor Test Facility in Qatar: Learned Lessons and Recommendations

Soiling of photovoltaic (PV) modules is a major issue due to its critical impact on PV performance and reliability, especially in the desert and arid regions such as the state of Qatar. Soiling frequently results in a severe reduction in PV power generation, which drastically affects the economical profitability of the PV plant, and therefore, must be mitigated. The most common way of mitigating PV soiling is surface cleaning. However, the latter could consequently increase the associated operation and maintenance (O&M) cost of the PV site. However, previous studies indicated that even if the best-optimized cleaning schemes are used, the actual global solar-power production can still be reduced by about 4%, which is associated with at least EUR 5 billion in annual revenue losses worldwide. This loss is expected to reach a conservative value of EUR 7 billion in 2023. Accordingly, investigating the interplayed physics phenomena related to the various soiling processes, the site-specific O&M costs, along with a techno-economical assessment of state-of-the-art soiling mitigation strategies (including innovative anti-soiling coating materials) is of paramount importance. The goal of this comprehensive report is to provide the solar community at large, and those focusing on the desert environment in particular, with real field measurements that provide key findings and challenges in addressing soiling research obtained from multiyear testing at the Outdoor Test Facility (OTF) field station, located in the desert environment of the city of Doha, in the state of Qatar.

Global warming has risen as a primary global concern. It has stimulated interest in the development of the renewable energy (RE) system. Studies demonstrated that the regions of Gulf Corporation Council (GCC) such as Bahrain, Kuwait, Oman, Qatar, Kingdom Saudi Arabia (KSA), and United Arab Emirates (UAE) face several changes in the form of uncertain weather conditions. Given the strategic location of the Gulf States and its enormous oil and natural resource, it is characterized to hold potential for using renewable energies such as solar, wind, and geothermal energy for meeting the power production needs. Previous studies suggested that energy consumptions such as crude oil and fossil fuels are the major sources of providing economic benefits to the states. The high oil price, deterioration of the financial markets, and incident of Arab Spring has shifted the working at a national and international level, making it important in using RE resources to generate excessive energy. The primary focus was to explore the scope of energy efficiency (EE) and the use of solar, wind and geothermal energy resources given their proliferation potential for the GCC region. The review assessed the energy and electricity consumption trends in the region. Also, it discussed the problems related to the effects of dust accumulation on devices. Moreover, it also highlighted the use of various computer interfaces that demonstrate the feasibility to use various RE technologies. Further, it draws conclusions and recommendations based on the issues.
