TL;DR: In this article, the influence of the measurement interval of solar radiation data on the cumulative probability distribution of the clearness index is studied, and a new statistical model is proposed, based on a mixture of two normal distributions, which provides a good fit for the data measured in Seville.

TL;DR: In this article, a simple and inexpensive test method to determine the thermal behavior of domestic water heating systems (SDWHS) is proposed, and the results of this procedure test can be very useful, firstly for the local solar manufacturers to design and optimize its products comparing their systems against a reference system under identical test conditions and secondly, by the consumers in order to select the most suitable system.

TL;DR: In this paper, it was shown that on days of low cloudiness level, nearly half of the direct solar irradiance stopped by cloudiness is scattered downward and nearly half upward.

TL;DR: In this article, a forced convection humidification-dehumidification process is analyzed, where air is forced into an evaporation channel while saline water flows along the bottom, so that a fraction will evaporate to be absorbed by air.

TL;DR: In this article, the monthly average values of Angstrom's Turbidity Coefficient (β) for the city of Seville for 1990 and 1991 were determined, based on the lqbal C Model.
