Solar submersible pump detailed introduction

Detailed introduction of solar submersible electric pump

1. Overview

Solar submersible electric pump is a water pump system that uses solar energy as a power source. The water pump is placed underwater and is suitable for pumping water from deep wells, rivers, lakes and other water sources. It converts light energy into electrical energy through solar panels to drive submersible electric pumps. It is widely used in agricultural irrigation, domestic water supply, industrial water and other fields.

2. System composition

The solar submersible electric pump system mainly consists of the following parts:

Solar panel (photovoltaic module):

The core component is responsible for converting solar energy into DC power.

Usually composed of polycrystalline silicon or monocrystalline silicon solar cells, the power size depends on the water pump demand.

It needs to be installed in a sunny place and adjusted at an angle to maximize the absorption of solar energy.

Controller:

It is used to adjust the voltage and current output by the solar panel to ensure the stable operation of the water pump.

It has overvoltage, undervoltage, overcurrent and other protection functions to extend the system life.

Some controllers also have MPPT (maximum power point tracking) function to improve energy conversion efficiency.

Submersible pump:

The core working component, installed underwater, is responsible for pumping water from low to high.

It is divided into DC submersible pumps (directly driven by solar energy) and AC submersible pumps (DC power needs to be converted to AC power through an inverter).

Select pump types with different head (water pressure) and flow (water volume) according to needs.

Cable:

Used to connect solar panels, controllers and submersible pumps to transmit electrical energy.

It needs to have waterproof and corrosion-resistant properties to adapt to underwater environments.

Water storage device (optional):

Used to store the extracted water, common forms include water tanks, water towers or pools.

Water storage devices can balance water supply needs and ensure that water is still available at night or on cloudy days.

Bracket:

Used to fix solar panels to ensure that their orientation and tilt angle are optimal to maximize the absorption of solar energy.

Brackets are usually adjustable to adapt to the sunlight conditions in different regions.

Pipes and valves:

Used to connect submersible pumps, water storage devices and water points to ensure smooth water flow.

The valve is used to control the direction and pressure of water flow.

Inverter (optional):

If an AC submersible pump is used, an inverter is required to convert the DC power generated by the solar panel into AC power.

3. Working principle

Solar energy conversion:

Solar panels absorb sunlight and convert light energy into DC power.

Power regulation:

The controller regulates the power to ensure that the voltage and current are suitable for the operation of the submersible pump.

Pump operation:

The power drives the submersible pump to pump water from a low place to a high place.

Water storage and water supply:

The extracted water is transported to the water storage device or directly supplied to the water point.

4. Advantages

Environmental protection and energy saving:

Using solar energy as energy, no pollution, and reducing carbon emissions.

Economical:

No external electricity is required, the operating cost is low, especially suitable for remote areas.

Independence:

Not dependent on the power grid, suitable for areas without electricity or unstable electricity.

Low maintenance:

The system has a simple structure, low maintenance cost and long service life.

High efficiency:

Submersible electric pumps are directly installed underwater, which reduces energy loss and improves pumping efficiency.

Wide applicability:

Applicable to a variety of water sources such as deep wells, rivers, and lakes.

5. Application areas

Agricultural irrigation:

Provide a stable water source for farmland, especially suitable for remote areas.

Domestic water supply:

Provide clean drinking water for rural or mountainous families.

Animal husbandry:

Provide clean drinking water and irrigation water for pastures.

Industrial water:

Provide water for small factories or equipment.

Ecological restoration:

Used for water supply in mountainous areas, deserts and other areas to support ecological restoration projects.

6. Selection and installation

Key points of selection:

Lift (water pressure): Select a submersible electric pump with appropriate lift according to the height of the water point and the length of the pipeline.

Flow (water volume): Select a water pump with appropriate flow according to water demand.

Solar panel power: Select appropriate photovoltaic modules according to the water pump power and local sunshine conditions.

Water storage capacity: Select a water storage device with appropriate capacity according to water demand.

Installation precautions:

Solar panel installation: Choose a sunny location and adjust the angle to maximize the absorption of solar energy.

Submersible pump installation: Make sure the pump is firmly installed and the cables are tightly connected to avoid air or water leakage.

Controller connection: Properly connect the solar panel, controller and submersible pump to ensure stable operation of the system.

7. Maintenance and care

Regular cleaning: Keep the surface of the solar panel clean to avoid dust or debris affecting the power generation efficiency.

Check the connection: Regularly check the cables, joints and pipes to ensure that there is no looseness, corrosion or water leakage.

Monitor performance: Regularly check the operating status of the submersible pump and controller to detect and solve problems in time.

Water storage device maintenance: Regularly clean the water storage device to prevent impurities from accumulating.

Winter protection: In cold areas, anti-freeze measures need to be taken in winter to prevent the pump and pipes from freezing and cracking.

8. Development prospects

Technological progress: With the improvement of solar panel efficiency and the improvement of controller technology, the performance of solar submersible pumps will be further improved.

Cost reduction: The reduction in the cost of solar modules will make solar submersible pumps more economical.

Application expansion:

In developing countries and remote areas, solar submersible pumps will become an important tool for solving water supply problems.

Intelligent:

In the future, intelligent control systems may be introduced to achieve remote monitoring and automatic operation.

Summary

Solar submersible pumps are an efficient, environmentally friendly and economical water supply solution, especially suitable for areas without electricity or unstable electricity. With the advancement of technology and the reduction of costs, it will play an increasingly important role in agricultural irrigation, domestic water supply, ecological restoration and other fields.
