PVGIS is a tool that provides global data on solar radiation and photovoltaic (PV) system performance, excluding the polar regions. 

It estimates potential electricity generation, seasonal variations, and battery storage benefits. 

Users can access hourly, daily, or monthly solar radiation data, as well as typical meteorological year datasets. 

The platform offers free, open access to PV potential for various technologies, requires no registration, includes APIs, and provides printable solar resource maps.
