This work is on solar water pumping machine. Solar water pumping systems are a modern but field proven means of pumping water in locations where access to grid power is not available, or where the grid is not reliable. These systems use photovoltaic (PV) cells to convert sunlight into electricity to power DC pumps which can be used to pump groundwater or surface water. The aim of this is to design a water pumping system for irrigation that uses solar energy for its operation
CHAPTER ONE
1.1 INTRODUCTION
A reliable and clean water supply is an essential need but a large number of people currently lack this basic provision. A solar water pump is a socially and environmentally attractive technology to supply water. Especially if the need for water is in remote locations which are beyond the reach of power lines, solar power is often the economically preferred technology.
Solar water pumps can supply water to locations which are beyond the reach of power lines. Commonly, such places relies on human or animal power or on diesel engines for their water supply (Omer, 2001). Solar water pumps can replace the current pump systems and result in both socio-economic benefits as well as climate related benefits. The water supplied by the solar water pump can be used to irrigate crops, water livestock or provide potable drinking water.
A solar water pump system is essentially an electrical pump system in which the electricity is provided by one or several PhotoVoltaic (PV) panels. A typical solar powered pumping system consists of a solar panel array that powers an electric motor, which in turn powers a bore or surface pump. The water is often pumped from the ground or stream into a storage tank that provides a gravity feed, so energy storage is not needed for these systems.
There are two main types of solar water pump technologies: a) the centrifugal pump, which uses high speed rotation to suck water in through the middle of the pump. Most conventional Alternating Current (AC) pumps use such a centrifugal impeller. However, when operating at low power the performance of the pump drops dramatically. This makes centrifugal pumps less suitable for solar applications, since low power due to cloudy weather is to be expected; and b) the positive displacement pump, which usually uses a piston to transfer water (Short & Thompson, 2003). Many solar water pumps use the positive displacement pump, which brings water into a chamber and then forces it out using a piston or helical screw. These types generally pump slower than other types of pumps, but have good performance under low power conditions and can achieve high lift. Since PV is expensive and is an intermittent power supplier, solar pumps need to be as efficient as possible.
1.2 AIM OF THE PROJECT
The project aims to develop a cost-effective, operation-robust, low CO2 emissions and environmentally-friendly multi-function photovoltaic (PV) water pumping technology (PVWP), to be applied for ecological restoration and desertification prevention.
1.3 OBJECTIVE OF THE PROJECT
1. To design a water pumping system for irrigation that uses solar energy for its operation.
2. To design a pumping system that minimizes human interventions.
3. To design a water supply system that makes irrigation more efficient.
1.4 PURPOSE OF THE PROJECT
The main purpose of our project is to supply steady water to consumer which can be utilized at affordable cost.
1.5 SIGNIFICANCE OF THE SYSTEM
Solar pumping system offers an alternate means to meet the electricity demand for irrigation and livestock watering. Under the circumstances of inadequate supply of electrical energy, the solar water pump can play a significant role. Among various renewable resources, solar energy has great deal for utilization in electricity generation. Therefore solar water pumping system has great prospect of utilization in this country. Battery and inverter would increase the stability of system.
1.6 APPLICATION OF THE PROJECT
Possible applications for solar pumping systems include:
- Irrigation and agricultural systems: The most common application of solar water pumping is to provide irrigation water or water for livestock, by pumping from groundwater wells or from surface water bodies. A well designed solar powered pumping system can transform the availability of irrigation water and reduce the money spent on generator fuel by farmers in areas where grid power is not available or is unreliable.
- Remote habitations: Where people live a long way from reliable power supply, solar systems can be a good alternative to generator power supply. While the initial capital cost of a PV system may be greater than a generator, over the life of the system the low maintenance and zero fuel costs will make a solar PV system the cheaper option in the long term.
- Temporary mining camps or construction camps: Solar pumping systems can be a great way to provide water to mining sites and construction sites. When used in combination with temporary drinking water treatment systems, they can be used to supply drinking water for workers.
- Emergency water supply: In disaster relief and refugee camp situations, solar pumping systems combined with temporary drinking water treatment units can be an effective way of very quickly providing safe and clean drinking water to affected populations. Solar powered systems are relatively lightweight and compact and suitable for air transportation. Once in the field they are quick to assemble and require little specialist knowledge to install and commission.
- Dewatering systems: Dewatering systems normally require continuous pumping, 24 hours per day, 7 days per week. This means that solar power alone will not normally be adequate, and dewatering systems are normally powered by generators or from the grid. However, in hot and arid climates, such as the Middle East, parts of Africa and Australia, solar PV systems may have a role to play in reducing energy costs by displacing part of the conventional power sources used to run dewatering pumps.
- Grid tie systems: If the required pumping is intermittent during daylight hours, or where the pumping demand is very low, the power output from the PV array may exceed the energy required to run the pumps. In these cases it is possible to connect the PV system both to the pump and to other electrical demands, either other on-site power demands of the pump operator, or to export power to the utility grid if that exists near the site. These systems are known as “grid tie” systems and can provide a source of income for the pump operator, by getting payments from the utility company for power exported.
1.7 PROBLEM OF THE PROJECT
- Potentially high capital costs
- Electrical output will be limited by daylight hours and bad weather. Water storage and battery backup may be required.
