Reliability Analysis of Bifacial PV Panel-Based Inverters Considering the Effect of Geographical Location

Recent trends in the photovoltaic (PV) technology industry are moving towards utilizing bifacial PV panels. Unlike traditional PV panels, bifacial PV panels can yield energy from both sides of the panel. Manufacturers specify that bifacial PV panels can harness up to 30% more energy than traditional PV panels. Hence, bifacial PV panels are becoming a common approach at low solar irradiance conditions to yield more energy. However, a bifacial PV panel increases PV inverter loading. The PV inverter is the most unreliable component in the entire PV system. This results in a negative impact on PV system reliability and cost. Hence, it is necessary to anticipate the inverter’s reliability when used in bifacial PV panels. This paper analyzes the reliability, i.e., lifetime, of PV inverters, considering both monofacial and bifacial PV panels for the analysis. Results showed that the increase in bifacial energy yield could significantly affect PV inverter reliability performance, especially in locations where the average mission profile is relatively high.

Doing and undoing gender: women professionals' persistence in technology occupations

PurposeThis study aims to identify women professionals' strategies to persist in the male-dominated technology industry situated in the Bangladeshi socio-cultural context.Design/methodology/approachIn-depth interviews with women tech professionals were conducted to identify and explore the strategies. Thematic coding was used for data analysis.FindingsThe findings suggest that the complex interplay of macro-, meso- and micro-factors pushes women to defy societal and gender norms in their choice and persistence, yet they simultaneously conform to these norms. By simultaneous expressions of doing and undoing gender, these women dealt with hierarchies and inequalities, navigated masculinized industry and empowered themselves within a patriarchal culture. The strategies effectively allowed them to demonstrate agency and persist in tech occupations.Research limitations/implicationsThe study participants were women and recruited using snowball sampling. Future research could benefit from recruiting a larger, more varied sample using random sampling.Practical implicationsThe study can inform teaching and policy initiatives to increase women's representation in tech sectors through awareness campaigns, policy interventions and counseling.Originality/valueThe research extends the doing and undoing framework by integrating the relational perspective to explain women's agency and resilience situated in a patriarchal context. The paper focuses on women's micro-individual strategies to navigate macro- and meso-level forces. Moreover, Bangladesh is an under-researched context, and findings from the study can help design potential intervention strategies to increase women's participation.
