Dc Solar Powered Water Pump Energy Saving Solar Submersible Well Pump

System Introduction
1. System composition
The DC solar submersible pump system is a deep well pumping solution powered by solar energy, mainly consisting of the following parts:

Solar panels: They convert solar energy into direct current energy through the photoelectric effect. They are usually made of monocrystalline silicon or polycrystalline silicon, and their power is matched according to the requirements of the water pump (such as 100W to 1000W).
DC submersible water pump: It is driven by a DC motor (such as DC 12V/24V/48V), and the pump body can work submerged in deep Wells. It features anti-corrosion and high-pressure resistance, and is suitable for water Wells at depths of 50 to 300 meters.
The controller includes an MPPT (Maximum Power Point Tracking) controller, which is used to optimize the power generation efficiency of solar panels. It also features overload protection, water shortage protection, short-circuit protection and other functions.
Energy storage system (optional) : Some systems are equipped with batteries (such as lead-acid batteries or lithium batteries) to store excess electrical energy and support operation at night or on cloudy days.
Pipelines and accessories: including water delivery pipes, check valves, wellhead supports, etc., to ensure stable water flow transportation.
2. Working Principle
During the day, after the solar panels generate electricity, they directly drive the DC submersible water pump to work through the controller, pumping well water to the surface water storage facilities. If a battery is configured, the excess electrical energy will be stored to maintain the operation of the water pump when there is no light. The system does not require grid connection and relies on solar energy to achieve self-sufficient pumping operations.
System Characteristics
1.Green and energy-saving, zero carbon emissions
It is completely driven by solar energy, does not require diesel or grid power supply, has extremely low operating costs, and emits no pollutants, which meets the needs of sustainable development.
Compared with traditional fuel water pumps, it can save thousands of liters of fuel every year and reduce greenhouse gas emissions.
2. Independent power supply, suitable for remote scenarios
It does not require the laying of power grids and is particularly suitable for areas without electricity (such as rural areas, mountainous areas, and pastoral areas), fieldwork or emergency water supply scenarios.
The deep well drilling pump system can be directly installed beside the water well, not restricted by the coverage of the power grid, solving the problems of drinking water and irrigation in remote areas.
3. Highly efficient and reliable, resistant to deep well environments
Dc submersible pump: It adopts permanent magnet DC motor, with an efficiency 10% to 20% higher than that of traditional AC motor. Moreover, its waterproof sealing design can withstand the high-pressure environment of deep Wells (such as 10 atmospheres generated at a depth of 100 meters).
Solar panels: They have strong UV resistance and weather resistance, and can still generate electricity stably in high or low temperatures or sandy and dusty environments.
4. Intelligent control and easy maintenance
The controller integrates MPPT technology, which can automatically track the maximum power point of the solar panel, increasing the power generation efficiency by 15% to 30%.
The system is equipped with self-checking functions for faults (such as shutdown due to water shortage and overcurrent protection), reducing the cost of manual maintenance. The impeller and pump body of the water pump are mostly made of stainless steel or engineering plastics, which are corrosion-resistant and have a long service life (usually up to 5 to 10 years).
5. Flexible configuration and strong scalability
The power of the solar panel and the model of the water pump can be adjusted according to the well depth and flow rate requirements. For example:
Well depth 50 meters, flow rate 5m³/h: Equipped with 200W solar panel + DC 24V submersible pump;
Well depth: 200 meters, flow rate: 10m³/h: Equipped with 800W solar panels + DC 48V high-head water pump.
Expandable energy storage systems or multiple sets of solar panels connected in parallel can meet the water demand at different times.
6. Cost advantage and significant long-term returns
The initial investment is higher than that of traditional water pumps, but there is no need for fuel or electricity. The cost can be recovered within 3 to 5 years, making it suitable for long-term usage scenarios (such as agricultural irrigation and community water supply).
Typical Application Scenarios
Agricultural field: deep well irrigation, orchard watering, farmland drought resistance;
Domestic water supply: Drinking water supply for remote villages, drinking water for livestock in pastoral areas;
Industry and Environmental Protection: Mine drainage, water circulation in sewage treatment plants, water for field engineering.
