Abstract: An instrument commonly used to measure diffuse irradiance is the polar-axis shadow band pyranometer. However, the shadow band that is used to prevent the beam energy from entering the pyranometer ...

Abstract: Solar energy applications require readily available, site-oriented, and long-term solar data. However, the frequent unavailability of diffuse irradiation, in contrast to its need, has led to the ...

Abstract: There has been an enormous increase in the use of solar heating and photovoltaic systems worldwide. Building professionals to better design buildings, windows and other solar related constructs ...

Abstract: Sunshine fraction, cloud amount, temperature, and global irradiation are the most commonly measured meteorological parameters. In this article five models based mainly on the abovementioned variables ...

Abstract: Diffuse irradiance is a fundamental component in solar resource considerations. Diffuse irradiance can be accurately determined by calculation from global and beam normal (direct) measurements. ...

Abstract: This paper presents arguments for the use of direct steam generation (DSG) in preference to other forms of generation in particular locations according to the prevailing environmental and economic ...
