The Photovoltaic Geographical Information System (PVGIS) is a free online tool developed by the European Commission’s Joint Research Centre (JRC). It provides detailed information and tools to estimate the solar energy potential and performance of photovoltaic
(PV) systems at specific locations around the world.
Key Features of PVGIS:
-
🌍 Global Coverage: Offers solar radiation and PV performance data for almost all regions worldwide, with particularly high-resolution data for Europe, Africa, and Asia.
-
☀️ Solar Irradiation Data: Provides monthly and yearly average solar irradiation values based on historical weather data.
-
⚡ PV Performance Simulation: Allows users to estimate electricity generation from a Solar Panels system by inputting variables such as:
-
Location (GPS or address)
-
PV system capacity (kW)
-
Panel orientation and tilt
-
System losses (e.g. inverter efficiency, temperature losses)
-
-
🧮 Custom Analysis: You can input your own data and adjust system parameters to simulate performance more accurately.
-
📊 Downloadable Reports: Generates detailed performance reports that include monthly energy output, irradiation levels, and system efficiency.
Who Uses PVGIS?
-
Researchers for energy modeling
-
Solar installers and engineers for feasibility studies
-
Homeowners and businesses exploring solar panel investments
-
Policy makers for regional planning and renewable energy strategy
