Solar Water Pumping
MORE THAN 1.2 BILLION PEOPLE LACK ACCESS TO CLEAN DRINKING WATER.
The benefits of solar water systems both economically and environmentally are undeniable. At Solar EPC, we take pride in offering the best products and services in solar water systems. From solar water pumps to solar modules, we have everything you need to implement a solar water system for potable, irrigation and livestock.
Solar water pumps are specifically designed to accept DC power directly from the solar modules and are optimized for operating under less-than-ideal sun conditions. Where conventional AC-powered pumps require a stable voltage and frequency to operate, solar pumps can operate over a wide range of voltage and available current.
Conventional AC-powered pumps require large amounts of power to move large volumes of water in a short period of time. Solar pumps typically move a smaller volume of water over an extended period of time. This method requires far less power, which minimizes the size and cost of the PV array.
There are several methods for pumping water in remote areas, such as windmills, gas/diesel pumps, and ram pumps. But most of these options are either too expensive to install, or for fuel and maintenance, or require specific site conditions to operate.
Solar pumps can work for most locations and are at full capacity when needed most: during warm, sunny days. In temperate regions, they can be used year-round—which can be particularly helpful for potable water, animal grazing, and other farming operations. For many sites, a solar pump is often the best option for reducing cost and labor.
In areas with a remote well and limited access to the power grid, solar pumps are the best option—particularly where utility power source is not reliable or not feasible. Specific applications include: Domestic water supplies for off-grid homes and community center. Although solar water pumps are used in this application, usually the home has an existing power system. In that case, it’s far more cost-effective to run an efficient DC or AC pump off that system.
Livestock watering for pond and stream protection, rotational or prescribed grazing, and remote pasturing. This is the most popular use for solar pumping systems. They have proven to be cost-effective.
Irrigation for small-scale applications. With the recent reduction in the cost of PV modules, solar irrigation is fast becoming cost-effective. Solar pumps are available that can move the larger volumes of water needed for irrigation.
