SOLAR WATER PUMPING FEATURES

A solar water pumping installation consists of a pump energized by solar produced electricity from solar panels (see diagram to the left). The quantity of water produced deppends on the intensity of the sunlight and the cloud cover. 


The water is pumped to storage tanks for consumption in order to stabilize the water supply without depending on sun conditions.  Water can also be pumped directly to sprinklers and drip irrigation tubing for irrigation.  


An installation consits of four components-


Solar Pump  Highly efficient solar pumps or conventional 3 phase pumps.


Solar Pump Controller that optimizes the solar electricity produced by the panels and supplies automatic operation of the solar water pumping system - automatic off in the event of dry water source or a full tank with automatic restart as the source accumulates water or the tank is emptied. 


Solar Panels in PV array or alone with the specific wattage for the necessary pressure and flow rates. 


Storage Tank sized for 4-5 days of consumption in installations for domestic or livestock use.

THE ADVANTAGES OF SOLAR WATER PUMPING

Any solar water pumping system is specific to the pump site. To plan an installation, the following information is necessary-


1.  Pressure Head (see diagram to the left) from the water level to the discharge point in addition to any other pressures and friction losses in the system for a sprinkler system or pressure tank, etc.  

 

2.  Water Volume daily or weekly


3.  Solar Conditions at the pump site.  An extensive data base is available of historical solar conditions.


4.  Pipe Length from the Pump to the Discharge Point


5.  Wire Length from the Solar Array to the Pump


The cost depends on the necessary pressure and water volume and sun intensity at the pump site.


Solar water pumping is competitive in cost with fossil fuel powered water pumps.

COSTS AND SPECIFICATION OF A SOLAR WATER PUMPING SYSTEM 

DAILY PRODUCTION OF 1000 TO 3,000,000 LITERES (250 TO 800,000 GALLONES PER DAY)

UP TO 1000 METER /3300 FEET PRESSURE LIFT

LORENTZ SOLAR WATER PUMPING SYSTEMS 

LORENTZ SOLAR WATER PUMPS ARE THE MOST WIDELY SOLD SOLAR PUMPS IN THE WORLD WITH A BROAD RANGE OF PUMPS FOR EVERY APPLICATION IN SUBMERSIBLE AND SURFACE PUMPS. LORENTZ PUMPS ARE HIGH QUALITY AND IDEAL FOR EXTTREME OPERATING CONDITIONS. PRODUCTION ESTIMATIONS ARE AVAILABLE FOR THE SOLAR CONDITIONS ON A WORLDWIDE DATA BASE.

AUTOMATIC OPERATION

WORKS FOR MANY APPLICATIONES

DAYTIME OPERATION ONLY

Up to a 300 meter/1000 foot

SOLAR WATER PUMPING IS COST COMPETITIVE WITH FOSSIL FUEL POWERED WATER PUMPING.  THE INITIAL PURCHASE PRICE IS THE ONLY EXPENSE.  FOSSIL FUEL POWERED WATER PUMPS HAVE ADDITIONAL RUCURRING EXPENSES IN FUEL, OIL, PARTS, AND MAINTENANCE. 


SOLAR WATER PUMPING CAN ALSO BE COST COMPETITIVE WITH WATER PUMPING POWERED BY THE PUBLIC ELECTRICAL GRID ESPECIALLY IN PUMPING INTENSIVE APPLICTAIONS SUCH AS POOL WATER FILTERING AND TRANSFER. 


EL COSTO DE UNA OBRA DEPENDE DE ALGUNOS FACTORES-


           1. MAYOR PRESION DE BOMBEO  ES MAS COSTOSO POR MAYOR POTENCIA DE PANELES SOLARES

           2. EXPENSES IN PIPING, WIRE, AND SOLAR PANEL MOUNTING

           3. SUN INTENSITY- MORE SUN MEANS LESS EXPENSE IN SOLAR PANELS


SOME EXAMPLES INCLUDE-


$1,500 TO $3.000 TO PRODUCE 1,500 TO 20,000 LITERS PER DAY UP 60 METERS PUMPING PRESSURE

$2,500 TO $3,300 TO PRODUCE 8,000 TO 10,000 LITERS PER DAY UP TO 40 METERS PUMPING PRESSURE

$9,000 TO $10,000 TO PRODUCE 50,000 LITERS PER DAY UP TO  60 METERS PUMPING PRESSURE

​NO BATTERY IS NECESSARY

STORAGE IN WATER TANKS INSTEAD OF ENERGY STORAGE IN BATTERIES


Get greater agricultural production with solar energy by irrigating crops on a daily basis with smaller volumes of water- without stressing the plants. 

HOW DOES SOLAR WATER PUMPING WORK?

FLOW RATE OF PUMPED WATER VARIES WITH SUN INTENSITY.

VERY LITTLE PRODUCTION IN RAINY CONDITIONS.

SOLAR PANEL WATTAGE CAN BE INCREASED TO PRODUCE MORE WATER UNDER CLOUDY SKIES.

HOW MUCH DOES A SOLAR WATER PUMPING SYSTEM COST?

WATER IS STORED IN TANKS FOR NIGHTIME CONSUMPTION

Solar pumping can get water from inaccesible places and drier water sources
