The food problem and energy problems have gotten worse lately. So solar water pumps are becoming a new way to integrate photovoltaics with traditional industries.
Like water conservation in agriculture, desertification control, domestic water, and urban waterscape.
Please click on the picture below to watch the video of how the solar water pump system brings stable water sources and convenient life to people in the Middle East.
In the Middle East, water resources are scarce, and traditional diesel or public utility grid-driven water pump systems are costly and polluting.
The emergence of the PVMars solar water pump system has solved the urgent water supply problem for the local area and helped agricultural production and sustainable development.
Needs of Middle Eastern customers:
Reliable and stable water supply: meet the daily water needs of crops and livestock in mountain farms, operate day and night, and support water level control of wells and reservoirs.
Simple and easy to operate: Since only farmers are operating on site, the system needs to be as simple as possible, and it is best to achieve unmanned operation and remote monitoring.
Economical and affordable: Considering the local economic situation, the overall system construction cost and subsequent maintenance cost need to be reduced.
PVMars Solar Pump System Solution:
Our photovoltaic water pump system is customized for the needs of customers in the Middle East.
With its high efficiency, energy saving, intelligent operation and maintenance, and economical and affordable characteristics, it helps the new era of agricultural irrigation.
System composition:
The photovoltaic water pump system is mainly composed of solar panels, PV combiner (optional), water pumps, inverters, cables, boost modules, etc.
Photovoltaic module arrays and junction equipment: The number and power of solar panels need to be configured according to the power of the water pump inverter.
Among them, the power of the water pump inverter should be 1.2 times the power of the water pump, and the power of the solar panel should be 1.5 times the power of the water pump inverter.
For example: 11kW well pump x 1.2 = 13.2kW, it is recommended to use a 15kW solar water pump inverter.
15kW x 1.5 =22.5kW, according to the best tracking MPPT voltage of the solar water pump inverter is 550V, considering the economic benefits, it is recommended to use 39 x 580W solar panels.
DC/DC and DC/AC pump inverters:
Ensure the maximum power output of the photovoltaic module (MPPT technology) and provide a voltage suitable for the working needs of the motor.
Water pump:
Provides water pumping power, and can be selected from brushless DC motors, brushless DC magnetic isolation motors, or three-phase AC motors.
Since the motor equipped with the water pump is an inductive load, special attention should be paid to the power matching of the water pumping inverter or dedicated controller when configuring the system.
Water towers and water supply facilities:
They store the water generated by the photovoltaic system during the day to meet the water supply needs at night.
Therefore, PVMars launched the PESPI200-4T solar pump system, which can realize photovoltaic DC and AC power supply at the same time.
Advantages of the PESPI200-4T solar pump system:
High efficiency and energy saving: The system starts automatically in the morning and stops automatically at night.
As long as there is sunlight, it can operate perfectly without backup batteries, public mains, and diesel generators.
The economic and environmentally friendly concept of using water storage instead of electricity storage directly drives the water pump to pump water, greatly saving the cost of system construction operation, and maintenance.
Intelligent operation and maintenance: Remote monitoring of real-time operation status and opening/closing through GPRS.
Unmanned automatic operation, remote monitoring, one-button start and stop on mobile phones, system data detection, and recording, are simple and convenient.
Economical: Fits all water pump applications. The overall system cost is low, the later maintenance cost is low, and the energy-saving economy of the photovoltaic water pump system is more than 50% higher than that of the diesel power supply.
The cost of photovoltaic power generation is about US$0.12 per kilowatt-hour, which is significantly lower than the use cost of diesel power generation of US$0.3-0.5.
Extend the life of the equipment: With frequency conversion control and 10 water pump protection functions, the overall system life is extended by 50%.
For example, in the case of overload, overvoltage, undervoltage, short circuit, phase loss, load loss, overheating, dry pumping, lightning strike, and other faults, the circuit is automatically disconnected to protect the motor.
Light-weak protection function automatically reduces the motor power when the light is insufficient to prevent overload of the photovoltaic system.
Conclusion
Our solar pump system has been successfully applied to more than 600 households in more than 30 countries and regions.
Such as Africa, the Middle East, Asia-Pacific, Europe, and the Americas, with an annual power generation of more than 100 GWh and an annual carbon emission saving of more than 120 Mt.
PVMars, the leader of photovoltaic water pump systems, helps usher in a new era of agricultural irrigation and create a green and beautiful future!
