Hours of Sunshine Times by Country
Hours of sunshine is a climatological indicator that defines the duration of sunshine over a given period of time. The production of solar energy is directly related to the amount of radiation in the project area. Like all weather-based renewable sources, solar radiation can change rapidly in time and space, and understanding of this variability is crucial in determining the financial viability of a solar energy project.
In solar system installation, global horizontal radiation, direct normal radiation and diffuse horizontal radiation values must be considered. In photovoltaic systems, the installation location is determined according to the global horizontal radiation values.
