Abstract

This review critically analyzes the design of sustainable energy systems implemented on islands and beyond. It emphasizes the importance of integrating renewable and non-renewable energy sources to enhance energy output in hybrid systems. Due to the Island's unique geographical and environmental characteristics, islands face distinct energy supply and sustainability challenges. The review examines different aspects of sustainable energy system design, such as renewable energy sources, energy storage solutions, grid integration, and policy frameworks. Hence, by synthesizing current research and case studies, this review aims to provide insights into effective strategies for designing sustainable energy systems that are specifically tailored to the needs and constraints of islands. This paper detailed the critical role of renewable energy sources such as solar, wind, hydro, and biomass in driving sustainability in island communities and urges energy stakeholders and policymakers to embrace their potential to effectively energize rural and underprivileged areas

Abstract

The efficiency of solar panels is significantly influenced by temperature and irradiance, which are crucial in solar energy conversion. As temperatures rise, solar panel efficiency typically decreases due to increased electrical resistance, resulting in lower output voltage and power production. This efficiency loss is quantified by the temperature coefficient, indicating the drop per degree Celsius above 25°C. Advanced cooling systems and optimal thermal management can mitigate these effects. Irradiance, the sunlight intensity reaching the panels, directly affects electricity generation. While higher irradiance increases efficiency by providing more photons for conversion, it can also raise temperatures, negatively impacting performance. Solar panels achieve maximum efficiency under optimal irradiance and moderate temperatures, typically 1000 W/m² at 25°C. Variations in irradiance due to geographical location, time of day, and weather conditions cause fluctuations in power output. Efficient system design must consider local irradiance patterns and utilize tracking systems to maintain optimal panel orientation. To optimize efficiency, innovative methods such as advanced materials, cooling techniques, and smart tracking systems are employed. Additionally, integrating energy storage solutions and predictive analytics helps manage environmental impacts. Proper design, installation, and maintenance strategies are crucial for maximizing solar panel efficiency and lifespan under varying conditions. Understanding the interplay between temperature and irradiance is essential for advancing solar energy technologies, and enhancing their reliability and effectiveness in diverse environments.

Abstract

The study aimed to examine the impact of COVID-19 on secondary education. It utilized a cross-sectional survey design, incorporating qualitative and quantitative methods. The research targeted 2 head teachers, 10 teachers, 36 students, and 7 parents, totaling 55 participants. The sample size of 80 respondents was determined using the solvens formula, comprising 4 head teachers, 24 teachers, 30 students, and 22 parents. Descriptive statistics were employed to analyze the data, with results presented through frequency counts and percentages. According to the study's findings, respondents noted that students received educational materials for home use, signifying that learning persisted through the home packages disseminated by schools during the COVID-19 period. The study ultimately concluded that delegating classroom operations and curriculum decisions to the community is a strategy to enhance the education system, improve teacher standards, and promote a school community for all students. Based on the findings, it was advised that adjustments be made at all education levels to adopt new strategies ensuring a continuous education process that is accessible, affordable, and flexible. Steps should be taken to prevent and address any disruptions in the education system, guaranteeing an uninterrupted flow of education

Abstract

This study investigates the relationship between the school environment and the retention of learners with disabilities in Universal Primary Schools (UPS) within Kasese District, Uganda. Employing a descriptive research design integrating quantitative and qualitative methodologies, the study examines three main objectives: the impact of teacher support, school infrastructure, and school relationships on the retention of learners with disabilities. A total of 154 respondents, including teachers, head teachers, and pupils from six selected UPS, participated in the study. Data collection involved self-administered questionnaires, interviews, and focus group discussions. Findings reveal various home-related factors influencing the retention of learners with physical disabilities, such as poverty, negative parental attitudes, and lack of essential self-help skills training. Despite respondents indicating moderate levels of school attendance and retention for learners with disabilities, enrolment and retention rates remain significantly lower compared to non-disabled peers. The study underscores the need for collaborative efforts among government bodies, school administrators, teachers, parents, and other stakeholders to implement sustainable measures aimed at improving the school environment and enhancing retention for learners with disabilities.
