SolarGIS is a geographic information system designed to meet the needs of the solar energy industry. It integrates solar resource information and meteorological data with tools for planning and monitoring the performance of solar energy systems. SolarGIS data covers most of the globe, but does not yet cover Canada, the United States, Japan, parts of Australia, and a few other regions. SolarGIS is trying to achieve global coverage by the end of 2012.
To provide clients with additional means of accessing their tools and data, SolarGIS has developed the Data Delivery and PV Planner Calculate APIs. The Data Delivery API retrieves the most recent data from the SolarGIS database and calculates the electrical output of a PV (photovoltaic) system. The PV Planner Calculate API is a simulation tool for the planning and optimization of PV systems.
