Abstract

Study assesses solar energy potential across Sabah, Malaysia, leveraging data from the Global Solar Atlas. Renewable energy sources, particularly solar energy, offer significant environmental and economic benefits by reducing dependency on fossil fuels. The potential for solar energy across different regions in Sabah has not been thoroughly assessed. Identifying regions with the highest solar radiation intensity and Peak Sun Hours (PSH) is crucial for optimizing solar energy systems and supporting policy initiatives for renewable energy use. The study aims to analyze solar radiation intensity patterns and calculate PSH across selected regions in Sabah to determine the most promising areas for solar energy development. Data on solar radiation intensity was collected from the Global Solar Atlas for Kudat, Kota Kinabalu, Keningau, Sandakan, Tawau, and Labuan. The data were systematically observed and recorded to ensure accuracy. Graphs were plotted to represent the solar radiation intensity data for each region, and PSH values were calculated. These values were compared with those from other studies to validate the findings and ensure reliability. The study found that Kudat had the highest monthly average solar radiation of 162.1 kWh/m² in April and the highest annual average of 1462.3 kWh/m². PSH values revealed Kudat as the most favorable location, with the highest PSH of 5.40 hours in April. The variability in solar radiation was observed with increased radiation during the dry season and decreased radiation during the monsoon season. Kudat emerged as the key region for solar energy development in Sabah, highlighting its suitability for solar energy projects. These findings provide critical data for optimizing solar energy systems and support policy initiatives to enhance renewable energy use in Sabah. This research underscores the importance of strategic planning and investment in renewable energy to promote sustainable development in the region.
