Rp-The Role of Solar Energy in Operating Styles of Irrigating Cultural Lands in in Holy Kerbala Province (Al Saqi Project as a Model).pdf

Abstract:
The problems of environmental pollution and depleting of the traditional power resources created from the industrial states’ voracity ( rapacity) in burning solid fuels resources, as well their high prices and the hard environment and economic problems accompanies. This all call us to take care to what Allah blessed our country including the innovated power resources where solar energy has priority with necessity of its use. However, our study is a humble attempt to define this power.
The geographical sight is considered the base of this study through what I had tackled the concept and constituents of solar energy and its role in irrigating agricultural lands particularly Ain ul Temur district that lies in the south west part of holy Kerabla province between the two latitudes ( 32 15- 4315-) north, and longitudes ( 43 15- 43 45-). The study focused on the geographical element influence ( natural and human) and their various reflections on the extent of the solar cells efficiency to generate electric power and its use in irrigating agricultural lands by sprayers Due to the emptiness of the study area from the surface water and its total dependence on the underground water.
The climate factor including its various elements has more impact through applying ‘ Pearson’ formula and Spss program as well the impact degree in solar cells efficiency. The study also clarified the impact of the human factors (population, scientific and technological progress, transportation and communication roads, and the capitals) on the extent of solar cells efficiency. The study also mentioned Al Saqi project belonging to Abbasi holy shrine as a sample to invest solar energy in Ain ul Temur district with an area of 10700 donums and more than 9000 donums were used in planting different types. The study showed through field studies and water laboratory analysis, increasing percentages of ( Ec,Na, Ca, So4, ph). The study also identified types of soil as sandy with high opaqueness.
The study focused on increasing of water consuming and average of (ETO) of crops during summer months according to Blany Griddle formula. The most important result of the study is the curved relation between the solar plates efficiency and temperature according to the readings taken from the solar plates from 10 o’clock in the morning till 4 o’clock afternoon, as well the influence of shade and dust on the solar plates efficiency and knowing criteria of choosing solar plates position.
