Floating solar is a type of solar photovoltaic (PV) system that is installed on water bodies such as lakes, reservoirs, and oceans. The potential for floating solar depends on a variety of factors, including the availability of water bodies, the intensity of sunlight, and the regulatory environment. In the UK, floating solar projects can be built on a large number of water bodies, including reservoirs, lakes, and other inland water bodies of UK and Malaysia. However, due to the UK's northern latitude, the region receives lower levels of solar irradiation compared to Malaysia is located closer to the equator and therefore, experiences higher levels of solar irradiation. The study aims to provide insights into the feasibility and viability of floating solar projects in these two locations, taking into account the unique characteristics and challenges of each country. By comparing and contrasting the potential for floating solar in the UK and Malaysia, the paper seeks to contribute to the development of sustainable and efficient renewable energy solutions that can help address the global energy and environmental challenges. The analysis is based on a comprehensive review of literature, satellite data, and case studies of existing floating solar installations in the two countries. The study gathers data on solar irradiation levels, water body characteristics (size, depth, temperature, etc.), wind speed, rainfall, water evaporation rate, regulatory framework and other relevant parameters using simulation tool. Based on the simulation results, of both locations, the relative potential of floating solar in the UK and Malaysia or compared. The findings of this study can provide useful information for policymakers, energy planners, and investors in determining the most suitable locations for floating solar projects.
