Solar water pumps are specially designed to utilize DC electricity from solar panels. The pumps must work during low light conditions, when power is reduced, without stalling or overheating. Low volume pumps use positive displacement (volumetric) mechanisms which seal water in cavities and force it upward. The submersible pump can realize working at sunrise and resting at sunset, no need any person look after it, no need diesel, no need power grid, and can be used with irrigation equipments to save water, energy and cost.
Solar water pumps are commonly used in residential and commercial applications. They are a clean alternative to fossil fuel powered windmills and generators. There are two main types of solar water pumps, surface pumps and submersible pumps. Surface pumps are located on the ground and move water through pipes, which can move large quantities of water slowly.
In remote areas where water resources are scarce and power grids cannot fully cover, people's lives, drinking water, and agricultural production are severely affected. In recent years, due to the rapid development of the photovoltaic industry, the cost has dropped year by year, and solar products have entered people's lives. Among them, the solar pumping system combines solar products with pumping water, and innovatively applies it to domestic water, agricultural irrigation, ecological restoration, grassland animal husbandry, etc. It not only avoids a large amount of capital investment in the construction of grid infrastructure, but also solves the problem of lack of electricity and water in agricultural production.
Solar water pump (also known as photovoltaic water pump) is mainly composed of photovoltaic pumping inverters, water pumps and solar panels. It is a powerful water supply method in remote areas with little electricity. Utilizing the inexhaustible solar energy that can be obtained everywhere, the system automatically works at sunrise and rests at sunset, without the need for guards and excessive maintenance. It is an ideal green energy water extraction system integrating economy, reliability and environmental protection benefits.
Correct choice of the solar company that will supply the solar system components is the base, success crucial factor and the first important task you should take care about. You need to find out more details about the solar company and solar components they provide before dealing with a certain. Here below, we shall summarize the clarifications you need to get, and better if it can be written signed/stamped clarifications from the best solar company:
In order to buy the correct pump, you need to know what flow rate and total head you will need.
Generally speaking, when the pump output pressure increases, the pump head increases, and when the pump output flow increases, the head will decrease. That is why some few pumps manufacturers use the pressure term instead of head to characterize the pump specs, but the head is still more useful and clearer term to assist you in the pump job evaluation.
In a certain application, if you need to pump a liquid for 40 ft, this means that you need to select a centrifugal pump with at least 40ft total head plus the friction losses, so it is better to select a bit little higher head to substitute for the friction to get required flow.
Pump head will not be affected by pumped liquid type as long as the liquid viscosity is low like water, so the head achieved by the pump will be almost the same.
1. Based on your installation location and expected whether all over the year, what will be the estimated annual electricity production generated from the solar system in kwh?
2. Of course in summer months, the solar electricity production will be higher than winter months due to the intensity of solar radiation, and the question is: What will be the estimated electricity production in kwh for the worst and best months?
The solar water pump is the heart of solar pumping system, so selecting the good reliable pump is a crucial choice in building your efficient system.
Mainly in the market there are 2 types of solar pumps: AC pump and DC pump.
DC solar pump uses DC motor which works based on direct current supply (such as solar panel or battery), so it does not need an inverter.
While AC solar pumps uses AC motor which powered via solar pump inverter that converting DC getting from solar panels to AC.
Then which one is better, AC pump or DC pump?
With the development of the solar power technology, and people's comprehensive considerations and strict requirements for water consumption, water quality, water supply system reliability and environmental protection, the solar water pumping system has increasingly become the preferred solution to the water use because of its easy installation, no labor guard, low cost and zero carbon emission and so on. The solar water pump system, or PV pumping system, is mainly constituted by solar panel, solar pump inverter, water pump, pipeline and water tank. In this system, the storage battery is omitted, and the water pump is directly driven, which has high reliability and reduces the investment cost.
Solar water pump system can provide water for remote district lacking of electricity or places where the electricity supply is unstable. In low-power solar pump systems, DC brushless motors are often used to drive pumps in order to achieve the highest possible system efficiency. We supply solar water pumps driven by brushless DC motors, which come with a DC controller. AC asynchronous motors are also used to drive water pumps in solar pump systems. In this case, the solar pump inverter is usually used for control. Both the DC controller and the solar pump inverter can convert DC power of the solar panel into AC power to drive the water pump. Also implements control and regulation on the operation of the system to achieve maximum power point tracking (MPPT). The solar water pump system is the most attractive water supply method in the sun-rich areas of the world, especially in remote areas where electricity are not available. Here are ten reasons why solar water pump system should be installed.
Solar photovoltaic water pumping system, also known as photovoltaic water pump or solar water pump system, converts solar energy into electricity through solar cell modules, and then drives the pump to raise water from low level to high level for farmland irrigation or human and livestock drinking. Solar water pump system project can be built in areas rich in solar energy resources, making modular construction or staged construction according to the fund or industrial development, and realize automatic operation, costs low management fees.
What is Solar Water Pump?
Tuesday, August 20, 2019
There are two main types of solar water pumps. The surface pump is located on the ground and moves water through the pipe. They can move a lot of water slowly. Surface pumps are often found on farms or large irrigation systems where water needs to be moved from the lake to the field. The submersible solar water pump is located underground, but the solar panel is connected on the ground. The submersible pump is used to move water from the well to the surface.
