ECONOMIC ANALYSIS AND INTERMEDIATION SYSTEM FOR PV-SYSTEM BASED ON GEOGRAPHIC INFORMATION SYSTEM

摘要

PURPOSE: A GIS(Geographic Information System)-based sunlight generation economic analysis system and an intermediating system are provided to ease a calculation process for sunlight generation by automatically calculating installation area by selecting a polygon on a GIS-based map. CONSTITUTION: A database(21) stores geographic information, independent variable data, weighted value data, power generation calculation data, and conversion data. An area data calculating unit(22) calculates area data of a selected spot. A power generation calculating unit(23) determines a spot from number data of the geographic information and reads the weighted value data and the independent variable data to calculate power generation.
