Solar Irradiance
Solar Irradiance describes the total amount of sunlight per square meter that is available at any particular location on the Earth’s surface and is a major part in estimating the solar irradiation at a particular point required to design a sustainable energy system using photovoltaic solar panels. The performance of a solar photovoltaic panel depends on many factors, but the amount of solar irradiance in peak sun-hours during the day that the solar panels receive during the day is of major importance
