Abstract

The goal of the paper is determining the available capacity of photovoltaic power generation density of a defined area through a modeling process using GIS. The method identifies the spots, and calculates the available area that receives solar radiation, taking into account geographical characteristics and spatial distribution of spots. Tilt and orientation are also considered to evaluate shading. The program identifies suitable spots valid for PV power generation. Power density is calculated from estimated values of available area and power, and data is corrected for horizontal plane that represents the reference for PV project evaluation. The method has the advantage of determining solar radiation and available area within high accuracy. The simulation results have been compared with the specific requirements for the configuration area, being within the established range, which proves the goodness of the method and verifies the availability of photovoltaic resources for the implementation of a power system. Keywords: ArcGIS, area sol, LIDAR maps, PV modeling, photovoltaic energy, power generation density
