Abstract This paper presents an extensive analysis of the UK’s largest bifacial photovoltaic (PV) power plant, located in North Yorkshire. Commissioned January 2020, this trailblazing facility, with a total installed capacity 34.7 MW, is benchmark for evaluation solar technology within region. pioneering study provides thorough comparative assessment and monofacial PV systems through methodical investigation their energy production, degradation rates, spectral responses over 4-year operational period. Our findings reveal that modules, distributed across four segments demonstrate remarkable average gain ranging between 15.12% 17.31% compared modules. Despite experiencing marginally higher annual rates—1.17% 0.91% systems—bifacial modules show superior resilience yield, particularly during winter months when albedo effects are pronounced due to snow coverage. The also highlights strategic importance response optimizing performance. Bifacial have shown greater efficiency capturing infrared radiation—a property could be exploited enhance overall yield under specific environmental conditions. empirical data indicate consistent performance normalized output clustering around expected level. Therefore, results pivotal understanding practical implications deploying on large scale. They provide valuable stakeholders sector, guiding future installations innovations panel technology.

To fully exploit the advantages of bifacial PV (bPV) modules and understand their performance under real-world conditions, a comprehensive investigation was conducted. It focused on bPV installations with some mounting constraints, as in industrial rooftops, where ideal high module-to-ground height for optimal performances is not feasible due to structural reasons. The experimental setup involved measuring I-V curves conventional diverse atmospheric including different solar irradiance levels ambient temperatures, well configurations. results show proportional increment power generation between 4.3% 7.8% if compared two gain 2 15% identical conditions. Additionally, negative potential influence structure observed. Small differences alignment module beams can virtually eliminate contribution, an estimated reduction up 8.5 W (a 3.43%).

ABSTRACT Potential‐induced degradation (PID) is a severe mechanism in crystalline silicon (c‐Si) photovoltaic (PV) modules. In p‐type c‐Si PV modules, PID results the formation of shunt paths on front side negatively biased cells relative to grounded frame due diffusion sodium ions (Na + ), phenomenon known as shunting (PID‐s). Various methods for PID‐s recovery, which involve outward Na , have been reported. However, whereas some show almost complete others exhibit no recovery at all. Conducting without knowing recoverability inefficient and wasteful; therefore, method identify recoverable non‐recoverable prior needed. this work, using current‐resolved electroluminescence (EL) imaging proposed module by evaluating their nature ohmic or non‐ohmic, depends concentration ions. A total 90 from three different modules are subjected recovery. The experimental varying degrees loss among tested cells. analysis highlights that non‐ohmic shunts greater potential than ones, finding further verified dark lock‐in thermography (DLIT). Furthermore, qualitatively provides insights into individual cells, establishing EL an effective tool assessing severity predicting This paves way future advancements diagnostics mitigation strategies within systems.
