The research aims to take advantage of the solar energy, as a free energy, to run a water pump powered by solar energy, and to study the effect of the intensity of solar radiation on the performance of this pump in Syrian coast conditions. This research has explained the necessary mechanism for determining the capacity of the pump and the electric PV panels required for the work of the pump and the area of these panels. Studying the effect of intensity of solar radiation on the performance of water pump through studying the impact of pump altitude and solar radiation intensity on water flow range at experiment location. It demonstrated that the flow of the pump is going through two phases with the increasing values of solar radiation during the day. It was found that the increasing value of the flow of the pump before the value of (520W/m2) of Solar radiation was greater than that after (520W/m2) and this led to the loss of a part of the solar energy falling during the day, especially on sunny days, and the value of the loss was about (27%) of the total amount of solar energy falling per day.

Research summary
تهدف هذه الدراسة إلى استغلال الطاقة الشمسية المجانية لتشغيل مضخة مياه في ظروف الساحل السوري، ودراسة تأثير شدة الإشعاع الشمسي على أداء هذه المضخة. تم شرح آلية تحديد استطاعة المضخة اللازمة والاستطاعة الكهربائية للألواح الكهروشمسية اللازمة لعمل المضخة ومساحة هذه الألواح. كما تم دراسة تأثير شدة الإشعاع الشمسي على أداء مضخة المياه من خلال دراسة أثر ارتفاع الضخ وشدة الإشعاع الشمسي على معدل تدفق الماء في موقع التجربة. أظهرت النتائج أن تدفق المضخة يمر بمرحلتين مع ازدياد قيم الإشعاع الشمسي خلال اليوم، حيث تزايد قيمة تدفق المضخة قبل قيمة (520W/m²) للإشعاع الشمسي كان أكبر منه بعد (520W/m²)، مما أدى إلى ضياع جزء من الطاقة الشمسية الساقطة خلال اليوم خاصة في الأيام المشمسة، وبلغت قيمة هذا الضياع حوالي 27% من كمية الطاقة الشمسية الكلية الساقطة في اليوم.
Critical review
دراسة نقدية: تعد هذه الدراسة خطوة هامة نحو استغلال الطاقة الشمسية في تشغيل مضخات المياه، خاصة في المناطق النائية. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الممكن توسيع نطاق الدراسة لتشمل فصول السنة المختلفة لتقديم صورة أكثر شمولية عن أداء المضخة على مدار العام. ثانياً، لم يتم التطرق إلى تكلفة النظام الشمسي مقارنةً بالأنظمة التقليدية، وهو جانب مهم لتقييم الجدوى الاقتصادية. وأخيراً، كان من الممكن تقديم توصيات عملية أكثر وضوحاً حول كيفية تحسين كفاءة النظام وتقليل الفاقد من الطاقة الشمسية.

This research aims to study the effect of the tilt angle of PV panels on the daily discharge a water pump powered by solar energy, and to determine the optimal tilt of these panels during summer months in the Syrian coast. The results demonstrated t hat the change of the tilt angle of PV panels from (25˚) to (35.5˚), has no effect on the curve of the solar radiation intensity and flow rate. However the resulting impact was represented by low amount of solar energy falling onto PV panels, resulting in a reduction in hydraulic energy of the pump and consequently low flow rate per day. The study showed that the amount of water flow rate at the two angels (25˚ and 22˚) for the tilt of panels was close, with preference for the angle (22˚). Reduction of water amount from one month to another during the months (June, July, August) didn't exceed (2.5%), while it was (7.5%) in September. At angle (35.5˚), water amount was approximately constant during June, July and August, while it decreased by (6%) in September. Flowing water largely decreased at angle (35.5˚) in comparison with the two angles (25˚and 22˚), so the reduction was (13, 12, 9 and 7.5%), respectively in June, July, August and September.
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 max imum 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.
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 th is 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.
The basic idea of the research is to deal with the problems facing floor solar heating systems (high Constituent cost, huge size of the storage tank, difficulty of implementation ...)in addition to fuel consumption. Despite the use of solar energy for the purpose of heating, that does not mean full dispensing for heaters assistance in order to increase the temperature of water in the days which the intensity of solar radiation is low.
In this study، a traditional air source heat pump was modified by adding secondary evaporator within hot water tank which acted as a water heat source of the heat pump. We made the heat pump to run alternatively either using surrounding air heat or water heat gained from solar power. We have done experiments during five months starting in December of 2014 until April 2015. Temperature and pressure were measured at specific points of the cycle. Then we defined the enthalpy at each point for both cycles using EES software (which is a software to simulate thermodynamic elements)، and calculated the amounts of heat gained in the evaporator، heat charged from the condenser، compressor work، coefficient of performance ، and electrical power consumed by the compressor. Then we made a compare between the two cycles and found that the improvement ratio in of the modified cycle to the traditional cycle was 77.07%، and the reduction ratio in electrical power consumed by the compressor of the modified cycle was 33.54%.
