Water for your family Solar pumps are used in private houses, huts, villages, medical clinics, etc. Pumps can be powered either by their own photovoltaic arrays or by the main system that powers the system. An elevated tank, or a second pump called a booster pump, can be used to provide the necessary water pressure. Or the main battery system can provide storage instead of tanks. When sunlight is scarce, rainwater harvesting can supplement solar pumping. In order to design a system, it helps to view the whole picture and consider all resources. Poultry water consumption Ranchers in the Americas, Australia, and Southern Africa are enthusiastic users of solar pumps. Their water sources are scattered over a wide range of pastures, with few power lines and high transportation and maintenance costs. Some ranchers use solar pumps to distribute pipelines for several kilometers (more than five kilometers). Others use portable systems and move them from one source to another. Plant water Solar pumps are used in small farms, orchards, vineyards, and gardens. It is most economical to supply pumps directly from photovoltaic arrays (without batteries), store water in water tanks, and then distribute pumps through gravity flow. When pressure is required, the battery stabilizes the voltage to maintain uniform flow and distribution and eliminates the need for storage tanks. Batteries also introduce cost, complexity and additional maintenance.

Solar photovoltaic pumps are also called photovoltaic pumps. That is to say, the photovoltaic pumping system is driven by the power generated by the photovoltaic array. The whole system is mainly composed of photovoltaic array, solar pumping inverters, and pumps. It is an optoelectronic-mechanical integration system that has developed rapidly in recent years. It is the most attractive water supply mode in sunny areas in the world, especially in remote areas where there is no electricity or electricity.
I. System Composition: 1. Photovoltaic arrays: also known as solar cell modules, mainly convert solar energy into electrical energy to provide working power for load pump motors. 2. Solar pumping inverters or controllers: the operation of solar pumps is controlled and regulated. The pumps are driven by the electric energy emitted by solar arrays, and the output frequency is adjusted instantly according to the change of sunshine intensity so that the output power is close to the maximum power of solar arrays. 3. Water pumps: Generally speaking, the machines that lift, transport or increase the pressure of liquids, that is to say, change the mechanical energy of the prime mover into liquid energy, so as to achieve the purpose of pumping liquids, are collectively called pumps. II. Operational process: Utilizing the power generated by solar cells, high-efficiency water pumps are driven by DC, permanent magnet, brushless, position sensor-less, stator-rotor double plastic-encapsulated motor or high-efficiency asynchronous motor or high-speed switched reluctance motor through maximum power point tracking, conversion and control devices.

It can be installed underwater and completely waterproof. The axis of the pump is made of the high-performance ceramic shaft with high precision and good seismic resistance. IIIThree-phase AC pump is driven by a three-phase AC motor. Unlike DC systems, solar AC pumps consist of the solar array (power supply), solar pumping inverters (converting DC to AC while controlling motor frequency) and three-phase AC motor pumps. Advantages: The three-phase AC motor pump in the system can be replaced by the AC pump driven by the market electricity or diesel engine, and the compatibility is very good. At the same time, AC pumps break through the power limitation of DC pumps. The power can be applied from 150 to 105 kW, which is suitable for large areas of farmland, desert control, and irrigation.

Photovoltaic pumps are increasingly recognized as the most attractive means of water supply in sunny areas of the world, especially in remote areas where there is no electricity or electricity. They use the available and inexhaustible solar energy to achieve high economic and reliable water supply. Usually, photovoltaic pumps (or solar pumps) refer to three kinds of AC pumps, recently named photovoltaic water pumping system. principle
The photovoltaic water pump system is an optoelectronic-mechanical integrated system which has been developed rapidly in recent years. It uses the power from solar cells to drive high-efficiency water pumps from the ground depths by means of maximum power point tracking, conversion and control devices, such as DC, permanent magnet, brushless, sensorless, stator-rotor double plastic-encapsulated motor or high-efficiency asynchronous motor or high-speed switched reluctance motor.

In fact, the use of photovoltaic solar pumps has always been around us, such as some fountains will install solar pumps, many of us will generally search the relevant knowledge of Photovoltaic Solar Pumps online when choosing to buy, then, what is the working principle of solar pumps?
First of all, when we understand the working principle of solar pumps, we should first understand what is solar pumps. After we do some simple understanding, we can easily understand the working principle of solar water pumps 1. What is a solar water pump? Solar pumps (also known as photovoltaic pumps) are mainly composed of photovoltaic pumping inverters, pumps, and solar panels. It is the most powerful way of water supply in remote areas where electricity is scarce and electricity is scarce. It makes full use of the available and inexhaustible solar energy to make the system full-automatic sunrise, sunset and rest, without personnel supervision, and maintenance workload is very low. It is an ideal green energy water extraction system integrating economy, reliability and environmental protection benefits. 2. Working Principle of Solar Water Pump Photovoltaic arrays absorb sunshine radiation energy and convert it into electrical energy, which provides power for the whole system. Solar pump inverters convert the DC output of photovoltaic arrays into AC and drive pumps, and adjust the output voltage and frequency in real-time according to the change of sunshine intensity to achieve maximum power point tracking. When the sunshine intensity weakens, the solar pumping water lifting system can realize the switching function of municipal electricity, which acts as a supplementary energy source for the solar pumping water lifting system. Above is the introduction of solar pumps. When we install solar pumps, we still need to consult suppliers to provide more professional installation services.
