Applying the measured global and diffuse solar radiation data from 78 meteorological stations in China, a countrywide general correlation model for calculating the daily diffuse radiation was derived on the basis of Liu and Jordan method. Two widely used statistics: root mean square error and...

Applying the daily global solar radiation data measured at least 10 years, the typical solar radiation year for 30 meteorological stations in China is generated using the Finkelstein–Schafer statistical method. Based on the typical solar radiation data obtained, the geographical difference of...

High sensitivity weather station from DIDCOT was used locally for climatically parameters measurements, during last two years, starting May 1st 1995 to June 30, 1997. Two different type of photovoltaic cells were belt-on to the set-up for current-voltage measurements, during the same period of time.

The Finkelstein–Schafer statistical method was applied to analyze a 34-year period (1975–2008) hourly measured weather data which includes global solar radiation, dry bulb temperatures, precipitation, relative humidity and wind speed in order to generate typical meteorological year (TMY) for...

Using ten years of solar radiation data, the surface albedo of twenty-four sites in the Kingdom of Saudi Arabia was calculated, and annual, seasonal, and geographical variations were investigated. The selected sites encompass a wide range of atmospheric conditions. The mean annual albedo values...

The typical solar radiation year for seven provinces located in the southeastern Anatolia region of Turkey is generated from daily global solar radiation measured at least for 14 years, using the Finkelstein–Schafer statistical method. The typical data of the daily global solar radiation for...

In recent years, renewable energy utilisation in various applications has increased significantly. Applications involving solar thermal energy include air and water heating whilst solar photovoltaic systems have been installed to provide electricity for households in urban and rural areas of the...

The knowledge of the amount of solar radiation in an area/region is very essential in the field of Solar Energy Physics. In this work two equations are put forward for estimating global solar radiation from common climate variables in data sparse regions. The first is the Hargreaves equation,...

Fifty-four broadband clear-sky models for computation of global solar irradiance on horizontal surfaces are tested by using measured data from Romania (South-Eastern Europe). The input data to the models consist of surface meteorological data, column integrated data and data derived from...
