Solar radiation is measured in a quantity called irradiance, which has standard units of watts per square meter. The average solar irradiance at the Earth''s distance from the sun is about 1,366 watts per square meter. Measurements of solar radiation tend to fluctuate somewhat over time. Part of the reason for this fluctuation is that Earth

Customer ServiceTo successfully implement solar power, all projects using solar energy must have access to reliable sun radiation data. However, the deployment, administration, and performance of photovoltaic or thermal systems may be severely impacted by the lack of access to and the ambiguity of this data.
The fundamentals of solar radiation are presented here. Irradiance and irradiation are defined; we explain the origin of the energy emitted by the sun and reaching the ground and its amount as a function of the wavelength – the spectral distribution. The energy reaching the earth depends on the geometry of the earth relative to the Sun.
The low price and the universal availability of solar energy make it the most important resource among the available renewables. Solar energy comes from the sun to the earth surface in the form of solar irradiation. As known, there are two components of solar irradiation: beam normal irradiance (BNI) and diffuse horizontal irradiation (DHI).
Therefore, precise forecasting systems are needed in order to increase the quality of the processes used to generate energy. The data on solar radiation may exhibit dynamic properties depending on the circumstances of the atmosphere. As a result, the process of modeling and forecasting solar radiation using artificial intelligence is significant.
The findings reveal that the nationwide annual mean solar radiation resources were decreasing at an estimated attenuation of −0.83 W·m −2 ·decade −1, with a downward trend of the greatest magnitude of −1.83 W·m −2 ·decade −1 for summer.
The collected data up to, and excluding time t are given as an input to an estimation model and it predicts the value of solar irradiation at the same time t as an output. The forecasting process consists in predicting future values of solar irradiation based on present and historical data.
