The main objective of this study is to develop single location appropriate models for the estimation of the monthly average daily global and diffuse horizontal solar radiation for Brasov, Romania. The study focuses particularly on models based on the sunshine duration and clearness index. The data used for the calibration of the models were collected during a period of 4 yr, between November 2008 and October 2012, at the Transilvania University of Brasov. The testing and validation of the models was carried out using data from the online SoDa database for Brasov for the year 2005. Different statistical error tests were applied to evaluate the accuracy of the models. The predicted values are also compared with values from three other known models concerning the global and diffuse solar radiation. A new mixed model was developed for the estimation of monthly average daily global horizontal solar radiation. The data processing was performed by means of a realtime interface developed with LabVIEW graphical programming language. The parameters taken into account were the relative sunshine, the clearness index, the extraterrestrial radiation, the latitude and the longitude. The methodology is simple and effective and may be applied for any region. Its effectiveness was proven through comparison with global models. V C 2014 AIP Publishing LLC.

A multitude of concentrating solar thermal power projects are currently being developed or proposed in many countries. Direct normal irradiance has an important impact on the optical-thermal conversion efficiency and rate of the plants. Though many researches focus on solar radiation, there are not many to emphasize variable air quality in different meteorological conditions. In this paper, aerosol optical depth of the atmosphere based on four wavelengths for three meteorological conditions in China has been experimented. To obtain solar radiation, two researches have been investigated as follows: the one is to calculate turbidity coefficients of the atmosphere according to Angstrom Law for different spectral aerosol optical depths, and another is to calculate the distribution characteristics of aerosol particles in the atmosphere and aerosol optical depths for the broadband using inversion method of experimental data. The results showed that the average value of turbidity coefficients for a clear day has a minimum of 0.9032 and the standard deviation has a maximum of 0.2870. The results also showed that the sizes of aerosol particle and aerosol optical depths for the broadband based on experimental values are different. The results can provide a reference to accurately calculate solar radiation.

This research compares the performance of the models to estimate monthly mean diffuse solar radiation (DSR) on a horizontal surface for composite climatic region of India. The goal is to identify the most accurate model using deterministic and probabilistic analysis through two levels of uncertainty in daily sunshine period to examine the accuracy of the model that will be used to estimate DSR in the region under consideration. The meteorological data were collected from Indian Meteorological Department for the city of New Delhi (28 34 0 N, 77 12 0 E) which comes under composite climatic region prescribed by the Energy Conservation Building Code for India.From the literature, 150 typical models were chosen and categorized into three categories correlating diffuse fraction to sky-clearness index and relative sunshine period.The models are statistically evaluated using well-known statistical indicators in a unique way. In addition, the global performance indicator (GPI) is calculated using scaled values of indicators. The GPI of the chosen models ranged from À2.2912 to 0.2584, with the greatest value indicating the best model. Following that, the models are then ranked in decreasing order of GPI. Finally, the performances of the models are also checked for different locations having similar climatic conditions. Thus, results of this work are useful for impoverished countries as well as remote areas having similar environment conditions.
