Unraveling the Secrets to Selecting a Solar Water Pump from 4 perspectives.

Why is a solar water pump so popular？

In today’s era, solar energy, as a clean, renewable energy source, is widely popular. With the wide application of solar energy, solar water pumps have also emerged. Due to its economy, reliability and environmental friendliness, solar water pumps are widely used in areas rich in sunlight, especially in remote areas lacking water and electricity. They play a crucial role in fields such as agricultural irrigation, desertification control, domestic water use, and urban water features.

What is a solar water pump？

A solar water pump is mainly composed of a solar panel, a controller/inverter and a water pump.

The principle is that the solar panel converts solar energy into electrical energy, and the controller is used to drive the water pump (or the inverter converts solar direct current into alternating current to drive an alternating current water pump) to lift water from sources such as deep wells, rivers, lakes and ponds.

Take irrigation scenarios as an example

However, at present, there are numerous types of solar water pumps, some are applied to small-scale household water supply, and some are suitable for large-scale agricultural irrigation needs; some are high-powered, and some are low-powered. Faced with so many solar water pump products, how should we choose the one that suits us?

Let’s move on!

How to choose a suitable solar water pump？

Four perspectives of choosing a solar water pump

Perspective 1: Clarifying the requirements is key.

A. Water consumption

The amount of water consumption will determine our choice of the type and power of solar panels and water pumps. If it is used for agricultural irrigation and livestock breeding, a water pump with a relatively large power is usually selected. At the same time, the irrigated area, the water demand of crops, and the irrigation frequency should also be considered. For household water use and small pool water supply, a water pump with a smaller power can be selected. We need to estimate the water consumption according to the number of family members and daily water usage habits.

B. Installation conditions

According to different installation conditions, we will also use solar water pumps of different types and powers to work. Here, installation conditions include lighting conditions, water source properties, etc. If the installation location is sunny, a solar panel with relatively small power can be selected. If the illumination intensity at the installation location is relatively low, a solar panel with greater power and an efficient solar water pump are needed. Moreover, depending on whether the water source is groundwater, a river, or a lake, it is decided to choose a surface pump or a submersible pump.

Water pumps classified according to application environments

Perspective 2: Consider the solar panel section.

A. Power of solar panel

The power of a solar panel determines its ability to receive and convert solar energy, and determines how much power it can provide to a water pump. The greater the power, under the same sunlight conditions, the greater the power of the water pump that can be driven. Generally speaking, we can choose the appropriate power of the solar panel according to the power demand of the water pump and the local sunlight hours. If the local sunlight is sufficient, a panel with relatively small power can be selected; if the sunlight hours are shorter or the power of the water pump is larger, a panel with greater power is needed.

B. Type of solar panel

At present, there are mainly two kinds of solar panels on the market: monocrystalline silicon and polycrystalline silicon. Monocrystalline silicon panels have high utilization efficiency of high light intensity, and can give full play to their advantages of high efficiency in areas with high light intensity, but the price is relatively expensive; polycrystalline silicon panels in the case of relatively weak light intensity, the advantage is more obvious, although the efficiency is lower than monocrystalline silicon, but in the light is not enough, the advantage of lower cost makes it cost-effective.

Perspective 3: Consider the water pump section.

A. Pump performance parameters

The performance parameters of a water pump mainly include flow rate ^[1], head^[2], and power^[3]. These parameters determine the working capacity and performance of the water pump. The flow rate determines the amount of water that can be transported within a unit time; the head refers to the height to which the water pump can lift water; the power determines the amount of water that the solar water pump can draw and the height it can lift. When choosing a water pump, we should select the appropriate performance parameters according to our own needs and the power of the solar energy system to ensure the normal operation of the system.

NOTE:

[1] Flow: The amount of water that can be transported per unit of time, measured in cubic meters per hour (m³/h) or liters per minute (L/min).

[2] Head: The height at which the pump lifts water from the surface to the outlet, measured in meters (m). The head determines the scope of application of the pump and the ability to supply water from a low water source to a high water source.

[3]Power: The work done by it in unit time, measured in watt (W). The power reflects the amount of water that the water pump can extract and the height it can lift.

B. Type of water pump

What types of solar water pump are there?We mainly have six types: solar submersible pump system, solar screw pump system, solar sewage pump system, solar centrifugal pump system, solar surface pump system and solar pool pump system. Each type of pump has slight differences in working principle and application scenarios, and also has its own advantages and disadvantages.

Perspective 4: Consider costs and benefits.

A. Initial investment cost

The price of solar water pumps is relatively higher than that of traditional water pumps. We can compare the product prices of different brands and models on the market and choose products with high cost performance. At the same time, we can also pay attention to the government’s subsidy policies and preferential measures to reduce the initial investment cost.

B. Operating costs and benefits

Solar water pumps have a low operating cost. They do not require external power sources and can operate only with solar energy. In the long run, they can save us a large amount of electricity bills. In addition, solar water pumps also have the advantages of being environmentally friendly and pollution-free, bringing many benefits to our lives and the environment. When choosing products, we should not only look at the price but also consider the quality and performance of the products to ensure long-term stable use.

In conclusion, choosing a solar water pump that suits you requires considering multiple factors, including your own needs, solar panels, solar water pumps, as well as costs and benefits. By comprehensively considering these factors, you can choose a solar water pump with excellent performance, reliable quality, and suitable for you, providing a reliable power source for your life and production. At the same time, using solar water pumps can also contribute to environmental protection. Let’s work together to build a beautiful world!
