This report gives a methodology in choosing the finest system throw for a particular habit regularly a mixture of techniques can significantly reduce price and advance the dependability of a pithing system or make available of a flexible architectural plan in order to verbal expression a large range of application.ADVANTAGES AND DISADVANTAGES OF SOLAR POWERAdvantages The use of photovoltaic in solar systems accounts for great life expectancyof the system (more than 20 years). Solar facilities operated with little maintenance or intervention subsequently initialsetup. Solar power is pollution free. Solar electric generation is economically competitive where power grid connectionor fuel transportation is difficult, make uply or impossible e.g satellites, remotelocations , ocean vessels and so forthDisadvantages P.V cells produce d.c which must be converted to A.C before using withA.C appliances To get enough energy for applications, a larger number of P.V cells beneeded. This increases the cost. Solar cells ar expensive, and require a large initial expectant whenpurchasing.Two typical ways of using solar water marrow are as representUsing a battery by charging it with solar photovoltaic panel and with the help of that pump outpouring the pump.Direct connecting between pump and the solar photovoltaic panel.Both this method also have their take backbacks which are as followMaking use of batteries by charging it by solar pump and than using it to break out the pump that mean we have to use two batteries while one is running at that fourth dimension other one will be charging which makes it more costly.If we are connecting solar panel today to the pump than the water will be pump barely during the sun glowing.IntroductionThe aim of this stu dy bailiwick is to fashion a solar based DC water pump which would be used in sylvan and isolated zones. There are ample amount of villages and t give births who do not have the liberty of possessing electric current supplies in their respective areas. By taking a look at the current scenario of our present economic choric. The solar water pumping system would be a benefited boon to the people. It not only saves the electricity but also in turn saves the wealth i.e. the capital. It is only easily available in the market but can be constructed as well.The development of the human kind has derived n number of methods of developing a water pump. The different rises of power used by people as a form of energy are as followHuman energy man power.Animal power cows, ox to pull out water.Hydro power at water dames and water bund.Wind power solar water heater, solar cooker, etc. cans such(prenominal) as diesel for small generator.The almost common pumps used in the rural and isolated c ommunities are hand pumps, borehole pump which are driven by fuel such as diesel, electric submergible pumps which are run by diesel generator last but not the least solar pumpFollowing are the different types of pumps with their advantages and disadvantagesAdvantageDisadvantageHand pumpCan be easily manufactured locallyEasy maintenanceLess capital costFuel cost zeroTrouncing of human efficiencyRepeated and unproductive use of boreholeFlow rates are minimalAnimal powerPrevailing than humansSubordinate remuneration than human power slime used as cooking fuelConstant food requirement to be met for animal regularly abstracted to other actions at critical irrigation periodsHydraulic pumpNo surveillance requiredFuel cost zeroEffortless to pertainStumpy expenditureLong lifeLofty accordInvolve precise location settingsLow outputWind pumpNo fuel requiredEasily manufactured locallyLong lifeNo supervision requiredEffortless to preserveWater has to be stored due to the scarcity of wind nau ghty project planning and system design neededDifficult to installSolar P.VZero fuel costLong life 20 years approxEasily manufacture locallyMinimum maintenanceCan be easily installedNo supervision requiredWater has to be cloudy stored for cloudy periodOften undergoes repairing skilled technicians requiredDiesel gasoline pumpEasily installedMinimal capital costUsed worldwideIt is portableFuel is expansiveHigh maintenanceShort lifeResult in noise fume pollutionAim Is to construct a solar water pump constituting P.V array .which would convert solar energy in to galvanic energy as direct current DC.Application of solar water pumpsWater supply for rural and isolated areas.Livestock watering.Irrigation.Village and water supply is very dominating. Though there is a very high demand of water storage for the period of low solar radiation during rainy anneal this demands can be met by rain water harvesting .the main application of solar water pumping are for livestock watering mainly in t he U.S and Australia .village water system and livestock watering are used in Africa where as solar water pumping for irrigation are mainly used in countries akin India and china where expositor of sun are very good.TechnologyP.V pumps constituents of the following components the P.V array converts solar energy directly in to electricity as direct current DC .the pump is driven by an electric motor. solely the different characteristic of these components ought to be matched to get the efficient result the pump motor unit has its own optimum speed and load depending on the type and the size of the pump.MotorTwo types of motor is world able to use such as DC motor or the AC motor .inverter is required if we are using AC motor .which exist more broadly .inverters have become low cost and are well organized. Electronic controller frequency -variable inverter is used mainly in solar pumping system. By which panel and the pump linking can be optimise in order to maintain and due to the method or the system is fewer proficient batteries are also required for a familiar AC motor system .The permanent magnet motor is generally proficient for a DC motor and CD motors might contain carbon brushes .when the brushed DC motor is being make into use than in order to change brushes roughly around every two years equipment required to pull out of the well. design without brushes are present in which as a replacement for commentators along with brushes electric circuits is use. The design without brush of DC motors needed electronic commutation which is being well the likes ofd in solar pumping system.PumpPresently are few type of different pump are in the funfair which include.Piston pump in this pump before the output piston movement of the pump draw water in a assembly room i.e.compartment.Thread screw pump in this pump water capsule is focused next to the screw in axial way. Starting from the opening to the way out for example cavity progressive pump, rotor coil helica l pump, and mono pump.Centrifugal pump in this pump impeller drive water for the exit with high revolving pace more or less near the frame up of the pump. In the middle of impeller situates an inlet from where the water is drawn.Following are the system configuration and the pumps option dictatorial displacement helical pumpsSimilar specs of water relief head as well as volume pressure positive displacement helical pump contains most excellent effectiveness with the least P.V panel. Their rotational speed is short. Inside a rubber covering a metallic helical rotor rotate .which is fit designed for greater head .during cloudy season mono solar pump is time consuming but due to its lowest speed water liquefy is continues not like centrifugal pump.Submerged pump with motor mounted on the surfaceBenefit for this type of pump isMotor maintenance can be easily accessiblePower victims ( losses) is shortly effected in shaft bearingsInstallation prise of the pump is high which is its disad vantage for which it is mostly replaced by submersible pump set as well as the motorFloating pump set motor collectable to its flexibility of floating .it is perfectly used in irrigation purpose of pumping water from canals as well as the well it is easily movable and there is a minor possibility of the pump operating dry. majority of this pump sets apply solo step submerged centrifugal pump. Majority of this type contain DC motor without brush frequently with solar array hold. want wheel barrow or handle. Like troll to permit transportSURFACE SUCTION middleSSurface suction pumps set is moreover charm in short head application because of its export system. It requires presence of operator for the purpose of its security as well as its maintanence.In order to have additional than 8 suction head is not possible . fever ordinary solar power pumps along with PV motorized reciprocating piston pumps or thermo phones as thermal solar pump are present which are not used commercially.SUB MERSIBLE PUMPPump with electronic load controller can be flooded with load controller preceding(prenominal) the earth or surface. It can be easily installed with lay flat pipe work and motor pump is positioned if flooded away from potential harm.MULTISTAGE CENTRIFUGAL PUMPIt can be switched on at low torque. With no electronic controller can be synchronized with the solar array it is not well organised as positive dislocation pumps with low cost electronic load controllers useful for short heads.Selection of the pumpPhotovoltaic pumps contain their influence rate as well as flow rate in order to design a P.V pump structure .following are the most important factors.Current voltage requirement of the pump.Tallness of the storage rootage i.e.tank as well as the deepness of the water resource.Mechanical job completed via the pump.Required flow rate.Price of the structure.The following are the promontorys that are measured for additional complicated designTube i.e.pipe line force allo wness.Temperature of the water.Heat as well as electric loss.Quality of the pump.The above points are not always needed in order to design complicated P.V pumps. It is required to realize the principal of water pumping.Following equation is used in order to verify flow rate conversion./h= /dWhere p /h = meter bloke per hour. /d = meter cub per day.Standard equal hour of solar power i.e.sun energy received for each day is equal to the raising sun hours which vary according to the site and the time of year.( /m), ( /m), (l/m), ( /s) this are the other unite which are used to measure flow rate of pump structure .WhereUsg/m = U.S congius per minute.Lg/m = imperial gallon per minute.L/m = litre per minute.Kg/s = kilogram per second.Understanding the principle of photovoltaic processThe working principal of photovoltaic irrigation system is quite straight forward. A photovoltaic array is the source of electricity for driving a surface motor pump. Which basically pumps out water from we ll reservoir into a accumulating basin. The P.V array contain 20 modules and each v trough module 50 west peak is made up of 36 square single silicon solar cells the pumping subsystem constitute of an MPPT maximum power point tracker and a motor pump. The components of motor pump are DC motor 746 watt unswervingly attached to a surface centrifugal pump.Photovoltaic pumping system efficienciesTotal efficiency of photovoltaic pumping system is defined as the product of efficiencies of the P.V array the pumping sub system .Where= P.V efficiencyIt is the ratio between operating electrical power and the incident radiation on the tilted surface of a photovoltaic module.Where= operating electrical power of the system wG = global radiance on P.V array w/ M = no of modules is parallel in P.V array= pumping sub system efficiencyis defined as the ratio between the output hydraulic power required for lifting a volume of water and the input electrical power of subsystem.WhereQ = water flow rat em = total dynamic head
