GIS-Based Solar Radiation Mapping, Site Evaluation, and Potential Assessment: A Review

Abstract

In this study, geographic information system (GIS)-based methods and their applications in solar power system planning and design were reviewed. Three types of GIS-based studies, including those on solar radiation mapping, site evaluation, and potential assessment, were considered to elucidate the role of GISs as problem-solving tools in relation to photovoltaic and concentrated solar power systems for the conversion of solar energy into electricity. The review was performed by classifying previous GIS-based studies into several subtopics according to the complexity of the employed GIS-based methods, the type of solar power conversion technology, or the scale of the study area. Because GISs are appropriate for handling geospatial data related to solar resource and site suitability conditions on various scales, the applications of GIS-based methods in solar power system planning and design could be expanded further.

Solar Power System Planning and Design

“…Choi et al [3] reviewed geographic information system (GIS)-based studies on solar resource assessments, especially for solar radiation mapping. GIS is beneficial for spatial and temporal analyses of solar resources while implementing location-specific technologies.…”

“…It is necessary to increase the effectiveness of installing solar power plants by prioritizing and selecting suitable locations to maximize electricity generation and minimize the damage that may occur. The results of such site evaluation can help solar utility companies, energy companies, and policymakers select potential sites for the construction of solar power plants [3].…”

“…GIS is useful for site evaluations when installing solar power plants for PV or CSP on the regional scale. Choi et al [3] reviewed the GIS-based methods for determining suitable locations for solar power plants. In most site evaluation studies, solar radiation is the primary consideration.…”

“…However, it is also necessary to consider economic, environmental, technical, social, and risk factors. These factors can be used to exclude unsuitable regions through a Boolean overlay and can be employed in various multiple-criteria decision analysis (MCDA) methods to estimate suitability indices [3].…”

“…Despite the advances in PV and CSP systems, inappropriate planning and design could impede the extensive penetration of solar energy. Systematic planning and design considering various factors and constraints are necessary to deploy PV and CSP systems successfully [3].…”
