Geospatial Assessment of Solar Energy Potential: Utilizing MATLAB and UAV-Derived Datasets

Solar energy is playing a crucial role in easing the burden of environmental protection and depletion of conventional energy resources. The use of solar energy in urban settings is essential to meet the growing energy demand and achieve sustainable development goals. This research assesses the solar potential of buildings considering shading events and analyzes the impact of urban built forms (UBFs) on incoming solar potential. The primary data for constructing a virtual 3D city model are derived from a UAV survey, utilizing drone deployment software for flight planning and image acquisition. Geospatial modelling was conducted using the MATLAB Mapping Toolbox to simulate solar irradiation on all the building envelopes in the study area in Jamshedpur, India. The empirical investigation quantified annual solar potential for more than 30,000 buildings in the region by considering time-varying shadowing events based on the sun’s path. The region’s annual solar energy of 310.149 TWh/year is estimated. Integrating UAV-derived datasets with MATLAB introduces a cost-effective and accurate approach, offering to develop 3D city models, assess solar potential, and correlate the impact of urban building forms (UBFs) to incoming solar potential.
