There is a growing awareness that combustion fuels are a limited resource and burning of these fuels is the principal cause of air pollution, and possibly environmental warming. This recognition is elevating interest and activity toward the development and application of alternative/renewable...

A model to convert horizontal solar global radiation to that on a tilted surface is presented. It is based upon a relatively simple model proposed by [Olmo FJ, Vida J, Foyo I, Castro-Diez Y, Alados-Arboledas L. Prediction of global irradiance on inclined surfaces from horizontal global...

The potential of solar energy development for water pumping in Jordan was studied. For this purpose, 10 sites were selected based on the available solar radiation data. According to the annual amount of water output, the selected sites can be divided into three different categories: the first...

The biological and photochemical effects of solar radiation and solar energy applications make it really important to characterize the variability of this component. In view of the fact that the clearness index indicates not only the level of availability of solar radiation but also the changes...

Solar radiation estimates with clear sky models require estimations of aerosol data. The low spatial resolution of current aerosol datasets, with their remarkable drift from measured data, poses a problem in solar resource estimation. This paper proposes a new downscaling methodology by...

The purpose of the study is to estimate the reference evapotranspiration of screenhouse-grown crops (ETo,in) from routine outside weather data and main screenhouse characteristics. To this aim, all the microclimatic variables required to calculate ETo,in by means of the standard FAO-56...

Chile is expecting a 5.4% growth in energy consumption per year until 2030, requiring new and better solutions for the upward trend of its electricity demand. This state leads to select and study one of the potential alternatives for electricity generation: concentrated solar power (CSP) plants....

The effect of thermal conductivity of the absorber plate of a solar collector on the performance of a thermo-siphon solar water heater is found by using the alternative simulation system. The system is assumed to be supplied of hot water at 50°C and 80°C whereas both are used in domestic and...

The measured hourly daily data of total, direct and diffuse solar irradiation incident on a horizontal and an inclined surface for Cairo, Egypt (Lat. 30°05′N and Long. 31°15′E), during the period (1990–2010) are analyzed. The regression equations between (G/Go) and meteorological...

This article presents a proposal for the implementation of photovoltaic systems in homes located in Mexicali, Mexico. With exhibition of new insulation and different consumption characteristics. The photovoltaic low power system is proposed as a type of electrical supply that helps in reducing...
