Retraction Note to: Temperature-based estimation of global solar radiation using soft computing methodologies

New Technique for Global Solar Radiation Forecast using Bees Algorithm (RESEARCH NOTE)

Estimation of solar radiation is the most important parameter for various solar energy systems. Expensive devices are required to achieve the amount of solar radiation for a special region, therefore different models have been proposed by researchers to estimate the solar radiation that obviate using such devices. Nonlinear nature and excessive dependence on the meteorological parameters of the...

Solar radiation: Cloudiness forecasting using a soft computing approach

Solar energy is one of the most important energy sources with increasing penetration into the power supply systems of many countries, due to the reduced environmental impact of its operation. One of the important factors of the efficiency of photovoltaic systems is the predictability of solar radiation, which depends on the clouds and the meteorological conditions, the occurrence of which is a ...

Using Solar Spatial Analyst to Calculate Global Solar Radiation, 22th Region of Tehran as the Case Study

Solar Radiation is considered as an important parameter in modeling environmental, hydrologic and biophysical processes. One of the reasons that solar radiations are not extensively used in models is the problem of its measurement in different points. Solar Analyst Viewshed Algorithm makes possible calculation of the topographic effects on solar radiation at local and landscape scales. With res...

Global Solar Radiation Estimation Using Sunshine Duration in Nigde

In this paper, several equations were employed to estimate global solar radiation from sunshine hours for a meteorological station in Nigde, Turkey, using only the relative duration of sunshine. These equations included the original Angstrom-Prescott linear regression and modified functions (quadratic, logarithmic and exponential functions). Estimated values were compared with measured values i...
