SWILLAS Solar Powered Water Pumping Systems

WHAT IS A SOLAR WATER PUMPING SYSTEM? |
| Pumping water is a sensible and effective use of solar electric power. During the hot months, when water requirements are highest, a solar pump will provide a reliable water source for the farm. Wind power, by comparison, can be inconsistent and may not be available during the hottest months in many inland areas. Wind may be too unreliable for water pumping when a relatively constant supply is required, as for stock watering. |
| A solar water pumping system is essentially an electrically driven pumping system. Electricity, in this instance is produced by the sunlight energizing photovoltaic (Solar) modules. |
A solar pumping system is available for almost all applications where an electric pump can be used. Because solar energy varies from one location to another, and over the course o f a day, system design is important. |
The typical solar cell is a thin wafer of silicon that transforms light energy into electrical energy. The cells are encapsulated in flat modules to protect them from the weather. Glass used on the front surface of the Module through which the sun's light travels to the cells, is of a low iron content to allow maximum transmission of the wavelengths which are converted to electrical energy and is tempered to withstand hailstones, much the same as motor vehicle windscreen glass is tempered to make it tough. |
Any number of modules can be connected together to form an array. The array is sized to meet a pumping system's power requirements. |
THE BENEFITS OF SOLAR PUMPING |
Solar pumping uses a free, easily accessible and renewable source of energy. Power bills are eliminated. With solar pumping, maintenance costs are minimized. |
Solar modules are strong, robust and encapsulated into toughened glass, tempered to withstand hailstones, in a sturdy, aluminum frame that will last even in harsh environmental conditions. Using solar allows opportunities for livestock, vegetables, trees and other crop production to be developed in areas where other forms of pumping are impractical. Solar water pumping systems are reliable. Solar systems won't fail on those hot, still days when the windmill stands motionless. |
Solar water pumps perform at their best and provide water throughout summer months when demand is greatest. |
Solar water pumping systems need little supervision requiring only periodic checking. Solar pumps automatically start soon after sunrise and continue to work unattended until sunset. |
Solar water pumping systems operate all year round, even on cloudy dull days with little or no direct sunlight. Solar water pumping systems can be designed to be transported for use at a number of sites. This can eliminate the need for multiple pumping units. |
Solar modules have no moving parts and an expected working life of at least 30 years. |
TYPES OF SOLAR PUMPING SYSTEMS |
Although solar water pumps have been developed from some fairly sophisticated 'hi-tech' components they are relatively simple, uncomplicated packages of equipment. Solar water pumping systems consist of three basic components: Power source (photovoltaic solar modules), motor/pump assembly, and power controller (maximizers/optimizers/m.p.p.t's) for matching the changing electrical output of the array to suit the motor/pump.

| Pre-assembled: Our systems are designed and assembled in our plant to make installation as simple as possible. The only connections required are for the pump and the float switch |
| Complete systems:Swillas solar systems are built from proven components that have been combined to work together to maximize the efficiency of the system. |
| Upgradeable: All of our systems are easily upgradeable to increase the power for additional pumping capacity or other electrical loads |
| By examining some variables, Swillas solar can put together the perfect solar, or wind powered water pumping combination for any purpose. All we need to know is the location, the water table depth and how much water is needed, and we will be able to find the most efficient energy source for the system |
| Series FS37 - Floating Submersible Pumping Systems - Designed to pump from a dugout, pond, lake or other open body of water. Designed for low lift (up to 20 feet) and high volume (up to 10000 gallons per day at 5 foot lift) applications. |
Series CF7 - Centrifugal Pumping System offers higher gallon per minute flow rates than our floating submersibles, as well as lift capabilities up to 30 feet, or up to 7,000 gallons per day. |

| SF 93 - Deep well Pumping Systems is small enough to fit into a 4 inch well casing, yet powerful enough to lift water over 200 feet. |
| SWILLAS SOLAR system is ideal for demanding applications requiring very high water volumes and lifts from a well or other water source - Lift up to 400', or up to 25,000 gallons per day. |
 
Solar Direct system. Require no batteries

Solar-powered pumps are available in a wide variety of configurations. If the water source is a dugout, floating pumps are available. If the water source is a well, submersible centrifugal pumps are often used. For dugouts, streams and shallow wells, self-priming surface centrifugal or positive-displacement pumps can be used. Whatever kind of pump is used, it is especially important in low-voltage applications like solar energy, that care is taken to ensure that the pump is matched to head and discharge requirements of the application. |
