As a renewable source of natural energy, solar radiation has great potential for a wide variety of applications, namely photovoltaics, because sunlight is abundant and accessible.
Solar radiation is unevenly distributed geographically throughout the world due to variables such as solar altitude, which is associated with latitude and season, and atmospheric conditions, determined by cloud coverage and degree of pollution.
The main tool to consult radiation levels is a radiation map.
To consult radiation maps for different regions in the world see, among others, the data published by the Photovoltaic Geographical Information System (PVGIS).
