Study of the effect of the addition of the booster on the performance of the basin solar still under the climatic conditions of the city of Homs

Solar energy being one of the most promising alternatives, this because of its availability and low cost compared to other energies. The device that uses solar energy to desalinate saline water is called the solar still. The problem at the solar still is reflected in its low efficiency, with the aim of raising it. This research presents a theoretical and experimental study for single-slope and single-basin solar stills.

Design of Photovoltaic Water Pumping System and economic feasibility study

In this paper, we present a system design of the photovoltaic pumping to provide electrical and economic comparison between two different energy supply systems: the first depends on the PV panels, and the second depending on the public grid. farm area study in the eastern countryside of Homs with the aim to supply water for irrigation and drinking.

Determining the Optimum Thermal Efficiency for a Prototype of a Parabolic Trough Solar Concentrator

The drastically increase in energy demand and the problems resulted from environmental pollution have led to a serious trend towards energy utilization efficiency improvement through scientific researches related to renewable energies, particularity that Syria has a high solar irradiance and prolonged sunshine hours. This research focuses on determining the thermal efficiency for a prototype of a parabolic trough solar concentrator (PTC) to obtain the optimal prototype thermally and economically according to climatic conditions in Damascus. It has been deposited the mathematical model of the studied concentrator depending on the calculated design parameters through calculating the solar angles equations and direct solar irradiance throughout the year. And it has been solved this model by using numerous computer programs (Excel, EES).

Algorithm of modeling the global solar radiation

Modeling solar radiation consider one of important and helpful matter in researches in generation an electric power from solar cells. Researchers interested in this subject and put number of mathematical models to modeling solar radiation. In this paper we will study one of this models (cloudiness degree model), then put algorithm for it, and based on it writing program using mathlab, then comparing this results with real value taken from position in Syrian Arabic.

Technical Study Of A Generation Electrical Power System By Two Source (Wind-Solar)

Solar and wind energy is considered as one of the best renewable energy resources because it Available and economical . We can take advantage of these two resources of renewable energy in Katina area in Homs for designing and building a bilateral resources (solar-wind) electric power system, depending on the daily bending of the wind speed and the solar radiation intensity in the studied area. This research studies the design of a hybrid wind and solar system by selecting its components that available in the local market in terms of their nominal, technical specifications, based on the technical and economic studies and the corresponding international standards. The obtained results showed that we have approximately (1246.7 Kw/Year) surplus during the year for the benefit of consumers, which makes the system economically feasible for investment, as explained in research needs an additional resource to feed the load and charge the energy-savings with (3360.2 w/day) that constituting (50.4 %) of the volume of the load in addition to the practical results provides a theoretical database, whether for the researcher or the investor in the field of renewable energies, particularly in terms of the efficiency of selecting the system’s components.

A Study of some Impact of Weather Factors on the Intensity of the Total Solar Radiation in the City of Homs

This research includes a detailed study of the daily and monthly changes to the intensity of total solar radiation in the city of Homs (34.75N °, 36.7 E °), and a direct measurement of the intensity. The study shows that intensity increases to maximum values in summer 1100w / m2, and drops to lesser values in winter 600 w / m2. The difference between the measured values in summer and winter is due to: a change in the inclination of the sun, and implicitly solar azimuth z. This angle is at its greatest in winter and the optical path is at the maximum. Thus, the processes of scattering and absorption increase. In summer, the inclination angle is at its lowest and the optical path is at the minimum. Thus, the absorption and scattering of solar radiation are at the minimum.

Studying the absorbance of some painted metals for the direct light

In this research we studied and measured the response and absorbance for some metals (zinc, copper, iron, aluminum) which are exposed to the direct light and painted with black, which has a high absorbance and low emittance, and with different thicknesses (to obtain black bodies) with higher absorption. we took the measurement on the painted metals for each thickness of the paint in the laboratory first using tow lamps 30 watt and 100 watt to compare the absorption of these metals of the radiation from these two lamps with the absorption of the solar radiation and make sure that the absorption is similar of the two situations, then we took the measurements in AL- Kadmous Area which is 900m above sea level using direct solar radiation , and we found the relationship between the absorbance and the paint thickness.
