DEVELOPMENT OF A WEBGIS FOR SOLAR PV RESOURCE AND INSTALLATION ASSESSMENT USING GEOSPATIAL TECHNOLOGIES

Abstract. The SINAG Web Portal, a web-based GIS platform that hosts spatial data and a forecasting model for solar PV installation assessment, serves as a repository for the products and outputs of the SolarPot and OutSolar components of a research project called Solar PV Resource and Installation Assessment Using Geospatial Technologies (SINAG). The website was developed with frontend and backend services which involved the use of a content management system, database systems, cloud virtual machines, Linux operating systems, programming languages, specifically Python and JavaScript, and a style scripting framework. All outputs generated by the two components of Project SINAG are stored on the dedicated cloud server of the website. It includes processed spatial data, a graphical summary of the created models, the ability to explore historical data, data requests and downloads, and the use of mapping tools. It is anticipated that the web portal will play a significant role in the assessment and decision-making process for selecting candidate sites for installing solar PV systems across the Philippine archipelago.
