Abstract
Today, Our World is facing economic crisis permanently due to high-energy prices and increased demand for traditional fuel or fossil fuels such as (oil, natural gas and coal). In addition, the planet is exposed to environmental pollution caused by the emission of carbon dioxide and other gases, which led to global warming and high temperature. On the other hand, renewable and sustainable energies are available in all parts of the world, which are clean, non-polluting, renewable and sustainable energy. One of the most important types of energy is Solar Energy, which has emerged as an important factor in the global economy and in the preservation of the environment. Therefore, it considered the best solution for the energy problems at all.
This study was conducted in two location, the first one was Ain Shams University, Faculty of agriculture, Egypt. The latitude and longitude of the experiment site are 30 º 04’ N, 31 º 17’ E respectively. Then in the experimental farm of soil and water Research Department, Nuclear Research Center, Located at Inshas City, Sharkia Government, and Atomic Energy Authority, Egypt. The latitude and longitude of the experiment site are 30⁰ 24’N, 31⁰ 35’E, respectively, Egypt, To Manage Irrigation System operated with Solar Power, Using Pumping system unit consisted of Centrifugal pump and DC Motor,
The study found that the best results obtained could be summarized as follows:
Irrigation was carried out at peak hours, there was two types of pumps was operated to provide the required water, the experiment was conducted with using the first type of pump from January to March while starting use the second pump from April to October. The system without batteries has the lowest cost of the system, which has batteries. The static head of the tank is 2 m. The distance experiment area and the tank was 20 m. one flow meters were used to measure the pumping on the ground in the piping system Moreover, as the power increases through the day until it reaches the climax in the middle of the day at the peak hours
1- The average value of hydraulic horsepower was minimum in January and April 872 and 1565 W/day respectively while it is increased in October and July 1.653 and 2.916 kW/day respectively this amount was enough to water the required space. The study showed that by changing the value of solar radiation changes the value of Hydraulic Power.
2- The average value of electric power consumption by the motor to operate the irrigation system, the data indicated that the lower value found in January and April while it is increased in October and July; 3.255,4.337, 5.401 and 5.189 kW/day respectively.
3- Maximum value of discharge for the sprinklers 9 m3 per hour at the pressure of running 15 m and the extent of the spread of water (radius of water around the sprinkler) 5 meters.
Recommendations:
Solar powered irrigation system Management in small-scale landscape is one of the cheapest methods used in the long run, contrary to what believe it is Expensive methods, especially as compared to traditional and the continued increase in fuel prices and the lack of availability in the new remote and urban communities easily. In addition, it is also considered a non-polluting energy.
1- To promote design and operation of sprinkler irrigation systems in the small-scale landscape by using Solar Energy and using pumping unit consisted of DC Motor.
2- Management irrigation system to match pump capacity with system requirements.
3- Using 4 panels with electric power 1 hp to get approximately pump discharge 7 mᶟ/h at operation pressure 1.8 bar and this Sufficient to irrigate turf area between 50 to 300 m².
4- Proposal for Solution fuel crisis.
5- Few ways to reduce this loss is cleaning of panels and cooling of the panels as at higher temperatures.
