20. Type of solar pumping

21. Surface Pump Jain Solar water pumping system is a stand-alone system operating on power generated by Solar Photovoltaic panels. The power generated by solar panels is used for operating DC surface centrifugal mono-block pump set for lifting water from open well or water reservoir for minor irrigation and drinking water purpose. The system requires a shadow-free area for installation of the Solar Panels.

22. special features of solar powered pump No inverter - D.C. motor connects directly to solar array Simple installation and maintenance Highly reliable Applicaion Village water supply Livestock watering Water supply to remote homes / agriculture Micro-irrigation Benefits No conventional grid electricity required Long operating life Highly reliable and durable Easy to operate and maintain Eco-friendly Saving of conventional fuels

The power generated by Solar Panels is used for operating Solar Submersible pump for lifting water from open well water reservoir or tube well for irrigation and drinking water. The system requires a shadow-free area for installation of the Solar Panels. Submersible Pump Highly reliable Eco-friendly No fuel cost-uses abundantly available free solar energy Long operating life Easy to operate and maintain Benefits

32. Different sprinkler pressures, flow rates and typical applications by solar power Sprinklers Pressure (m) Flow rate (m 3 h -1 ) Typical application Low pressure < 20 < 0.7 Orchards Medium pressure 25-40 < 3.0 Cash crops High pressure > 40 < 50.0 Pastures and sugar-cane High volume > 45 20.0-100.0 Pastures and maize (Burger et al ., 2003c) Rome, Italy

33. The water application efficiency of a micro sprinkler irrigation system ranges from 80 % to 90 % depending on the level of design and irrigation system management. Godin and Broner , 2013. Compared to furrow irrigation, the integration of micro- sprinkler irrigation with solar water pumping systems is ideal due to the low pressure and high water use efficiency of the system, meaning the sizing of the solar panels will not be too large resulting in very high investment costs Goswami and Zhao, 2009.

34. 3 . Automated Irrigation System Using Solar Power Setup of Solar powered automatic irrigation system Chittagon, Bangladesh Uddin et al ., 2012

35. This system mainly consists of two modules Solar pumping module. Automatic irrigation module .

36. I. Soil moisture sensor: A moisture sensor is used to sense the level of moisture content present in the soil. It has a level detection module in which we can set a reference value. With the help of moisture sensor signaling a controller, a Control pulse is given to the driver circuit that excites the motor. So the pump starts working and moves water to the irrigation field as per the soil moisture content. When the soil moisture content reaches the required value, the motor is stopped and power to driver circuit is stopped and controller is put into sleep mode for low power consumption. Soil Moisture Sensor

37. II. Temperature sensor Temperature of the field is sensed by a Thermistor shown in fig. Thermistors typically achieve a greater precision within a limited temperature range, typically −90 °C to 130 °C. Temperature sensor

39. Economics

40. Net present value (NPV), benefit cost ratio (BCR) and internal rate of return (IRR) at 15 % discount factor Bangladesh Hussain et al ., 2015 Diesel pump Solar pump BCR NPV (US $) IRR (%) BCR NPV (US $) IRR (%) 1.31 13,423 71 1.91 13,756 80 NOTE: BCR: Benefit Cost Ratio NPV: Net Present Value IRR: Internal Rate Of Return

41. Result compare to normal system Low operating cost : One of the important advantages is the negligible operating cost of the pump. No fuel required. Low maintenance : A well-designed solar system requires little maintenance beyond cleaning of the panels once a week. Harmonious with nature : Another important advantage is that it gives maximum water output when it is most needed i.e. in hot and dry months. Slow solar pumping allows us to utilize low-yield water sources. Flexibility: The panels need not be right beside the well. They can be anywhere up to 20 meters.
