Solar energy Irrigation System using FINAL REPORT
1. Abstract We're using Non renewable sources of energy in excess mount for our needs. As this type of minerals like coal etc. are exhausting so we have to depend on the renewable sources of energy like solar, wind, etc. For smaller application it is better to use renewable energy. As this project is based on water pump and required AC supply. So for this particular application we are using solar panels to charge the DC battery and the power from the battery can be used for this application. This project is an innovative solution to operate a machine / motor / liquid pumps for a small duration. If a machine is to be operated for ten minutes, and should be switched off after the duration, it is too difficult and many times we forget to switch it off the system after the prescribed time. This project provides the facility of automatic switch off after the requited time duration. This is achieved by using the pic microcontroller. Four push-to-on switches are connected to one port of the microcontroller. These four switches are to provide four different fixed time constants. A LCD is connected to the microcontroller to display the status of the pump. Contrast of the LCD can adjust by using a preset which is connected to it. A transistor is used to drive the relay during the active time period. 5V double pole – double through relay is used to control the AC liquid pump. LED indication is provided for visual identification of the relay / load status. A switching diode is connected across the relay to neutralize the reverse EMF.
Technical and Economic Feasibility of Solar Irrigation Pumping System: A Review
Knowledge-Based Engineering and Sciences, 2020
Climate change has become a major constraint to the development of rain-fed agriculture due to the decline of rainfall. Therefore, irrigated agriculture is an alternative allowing farmers to have more access to water in order to meet crop water requirements. However, irrigated agriculture faces a major constraint related to the accessibility of energy sources used in pumping water. In general, the most common energy sources used in pumping water for irrigation are fuel and electricity. Nevertheless, they are very expensive, are not always accessible particularly in rural areas in Africa and have a negative impact on the environment; hence the need to find alternatives to solve this problem. This review focuses on the technical and economic feasibility of solar irrigation pumps and the impact of their use on the environment. Several aspects related to solar pumping have been discussed, namely the components of the solar pumping system, the energy source used, the principle of operati...

India′s smallholder agriculture boomed with supplemental irrigation made possible by diesel and electric pumps. Nevertheless, the smallholders' irrigation is under siege from an energy squeeze with deteriorating farm power supply and manifold increase in diesel prices. This energy squeeze undermines the adoption of broad range precision irrigation technologies and profitable productivity of small holdings. However, the use of solar energy particularly in groundwater pumping and use of pressured irrigation could improve energy access, reduce fossil fuels 2 consumptions, as average incident solar radiation over India's geographical area is of 4-7 kWh/m / day with 250-300 clear sunshine days/year. To promote solar energy use under the prevailing solar radiation conditions and depth to water level scenario of groundwater a suitable groundwater pumping system model is required to fulfil the irrigation needs. This paper describes a solar photovoltaic groundwater pumping model suitable for small farm irrigation ether by traditional methods of irrigations or by pressured method, as it generates pressure heads of 98-147kPa when 2 incident solar radiation ranged from 400-800W/m , the solar radiation condition which prevails over its geographical area between 9.00-14.00 hrs round the year.

This research paper studied the technical evaluation of solar pumping and pressurized drip irrigation systems to investigate the recommended water required for suggested tomatoes crop in area of (one hectare) at AL-Salman district using measured climatic data from AL-Salman Agro-meteorological weather station for a period (2013)(2014)(2015)(2016)(2017). The maximum average monthly of solar radiation was 7.6 kWh/m2 at June in all the years of recording data, while the minimum average monthly value was 3.37kWh/m2 at December where the sun at lowest point across the sky. The annual average hours of peak sun that corresponds to the operation time of the pumping system at maximum water consumption was calculated at eight months from March to October with a value of 7.2 hours/day, while it was 5.2 hours/day during the other four months (January, February, November and December). The Solar pumping sizing based on H-Q performance curve of a maximum flow rate of 64.45 m3/h and pump capacity of 16.79 kW with compounds motor pump efficiency of 61.2%. The total water production was 230000 m³/per year which indicates compatible overall system design and adequate to irrigate more planting land with same or other crop types.

Egypt's demand for electricity is growing rapidly and the need to develop alternative power resources is becoming ever more urgent. It is estimated that demand is increasing at a rate of 1,500 to 2,000 MW a year as a result of rapid urbanization and economic growth. Egypt is now struggling to meet its own energy needs. Egypt has been suffering severe power shortages and rolling blackouts over the past years, necessitating the requirement to look to alternative energy options. Energy demand is increasing fastly so as to meet the requirements of growing population in the world. This study aimed to compare between traditional energy and solar generators in terms of energy consumption and cost effectiveness. Pumping systems were used to operate units of drip irrigation for the crop which was planted, so as to determine the best and least expensive energy consumption under this system. The required hydraulic experiment and measurements were performed on a private farm at Beni Salama, Giza which lies at latitude 30.32°N, 30.80°E during 2016 and 2017. Measurements were done at two days randomly selected in the months of December and March. This study evaluated the average monthly measurements for December 2016 and March 2017 where onions were grown. Maximum and minimum for Pv system DC power output were 6398 and 5755 W, the maximum and minimum for AC current were 5814 and 5548 W, respectively. Maximum and minimum for hydraulic power were 5911 and 3553 W, respectively. Efficiency of both photovoltaic, inverter, pump and overall system were also calculated for these days. Maximum and minimum for module efficiency were 14% and 13.2%, respectively, and maximum and minimum for inverter efficiency were 95%, 89%, respectively. Maximum and minimum for pump efficiency were 64%, 54%, respectively. While for overall efficiency, they were 8% and 3%, respectively. The results showed that solar pumping system is a reliable system.
