Solar power irrigation system

In light of the increasing challenges facing the agricultural sector, especially those related to water scarcity and the high costs of traditional energy, solar power irrigation system have emerged as a sustainable and effective solution to support farmers and achieve food security. These systems rely on exploiting clean solar energy to pump water and transport it to the fields, which reduces dependence on expensive and environmentally polluting fossil energy sources. In this article, we review the components of a solar power irrigation system, the most important benefits of using solar energy in irrigation, and the steps for specifying a solar power irrigation system. 

Solar irrigation system components 

The solar power irrigation system consists of a group of components. These components are:

• Solar Panels

These panels convert sunlight into electrical energy. This electrical energy is used in the pumping and irrigation system.

• Solar Water Pump

It is a pump powered by electrical energy generated by solar panels. This pump may be surface or submersible, depending on the water source: a well, tank, or river.

• Charge Controller 

This regulator controls the flow of electricity to the batteries to prevent overcharging or deep discharging; Therefore, this part is linked to the presence of the battery, and if it is not present, it is not used. This part is also used To improve Battery life and system efficiency.

• Batteries

The use of batteries in the system is optional, as they are used to store solar energy for use in weak sunlight or during the night; Therefore, it is not necessary in systems that operate only during the day.

• Solar inverter for irrigation systems (Inverter) 

Converts direct current (DC) from panels or batteries into alternating current (AC) for conventional pumps.

• Mounting Structures

They are used to mount solar panels and orient them at appropriate angles to obtain the best exposure to sunlight.

• Pipes and Irrigation System

What is meant is the connection network between the water source and the fields.

• Sensors And control Intelligent (optional)

Some modern systems include soil moisture sensors and smart control systems to automatically adjust watering and solar power irrigation system as needed.

Solar water pumps 

They are special pumps that operate using electricity generated through solar panels, which is one of the components 

Solar irrigation systems: These pumps are used to pump water from wells, rivers, or tanks for irrigation or drinking purposes, without the need for traditional electricity or fuel sources. There are many types of solar water pumps, these types include the following:

• Submersible Solar Pumps: These are installed under the surface of the water inside a deep well or tank, and are ideal for raising water from great depths.
• Surface Solar Pumps: These are installed above the ground and used to draw water from a shallow depth. They are suitable for shallow rivers, ponds, or reservoirs near the surface.
• Multistage Pumps: Designed to provide high pressure when pumping water over long distances or to high altitudes is required. Used when the horizontal or vertical distance of water pumping is large.
• Centrifugal Solar Pumps: These pumps force water by using centrifugal force resulting from the rotation of the fan inside the pump. It is suitable for sprinkler irrigation or irrigation of large fields.

Steps to specify a solar power irrigation system 

Since there are many solar energy systems that the customer can choose from, the experts at Cairo Solar show us some steps that can help the customer choose the system that is appropriate for him. These steps include the following:

1. Determining daily water needs: Needs are determined by calculating the amount of water required for irrigation daily in cubic meters or liters. Calculating this amount of water depends on: the type of crops, the area of ​​the land, and the nature of the soil.

2. Determine the water source: Is the water from a well? river? Ground tank? Because determining the depth helps in choosing the system accurately.

 3. Choosing the appropriate type of pump: This point includes two factors: the type of pump and its capacity, as there is a surface pump used with a depth of less than 10 meters, And pump Submersible, which is the most suitable option if the depth is greater than 10 metres. Choose the pump capacity and desired flow rate in litres/hour and the required pressure.

4. Calculating the energy needed to operate the pump: It can be calculated using this simple equation (calculating the total daily energy needed = pump capacity x daily operating hours).

5. Determine the number of solar panels: This is done through:

1. Calculate the total energy required daily.
2. Divide this energy by the number of hours of actual solar radiation in your area.
3. Choose the number of panels so that they provide this energy with a margin of safety.

6. Determine whether the customer needs batteries: If the system operates only during the day, the batteries are of no importance or use, and vice versa, if irrigation is required at night or in cloudy conditions, batteries must be added. for storage.

7. Inverter selection (Inverter): If the pump is powered by alternating current (AC), in this case He will need The customer turns to a solar inverter that converts current from DC to AC.

8. Designing the irrigation network: by choosing the appropriate irrigation method, and then designing the pipes and valves to suit the pressure and water flow rate.

9. Study the installation location: Choose the best place to install the solar panels so that they receive direct sunlight for the longest possible period of time daily without shadow.

10. Check the budget: by comparing offers from different companies, calculating component costs, and choosing the cost that is in line with the budget.

Benefits of using a solar power irrigation system 

There are many advantages that can be obtained when using solar energy in agriculture and irrigation, including the following: 

• Saving energy and reducing costs: solar power irrigation system rely on the free energy of the sun, which reduces the costs of electricity or fuel used to operate traditional irrigation pumps.
• Sustainability and environmental protection: Solar energy is clean and renewable, and reduces carbon emissions and air pollution compared to traditional diesel or electric irrigation systems.
• Self-reliance: solar power irrigation system allow farmers in rural areas to operate irrigation systems without the need to connect them to an electricity grid or buy fuel regularly.
• Lower maintenance costs: Modern solar energy systems require less maintenance compared to traditional generators, saving additional time, effort and money.
• Autoplay Wemmern: The system can be linked With timers Or humidity sensors, allowing automatic control of the irrigation process according to the actual need of the plants.
• Improving irrigation efficiency: By using solar pumps, water distribution can be improved and waste reduced, which results in increased crop productivity.

Systems solar power irrigation system

There are many types of solar power irrigation system, the most popular of which are the following:

• Solar drip irrigation system

This system is used to pump water slowly And to deliver Water to the roots of plants through pipes with drainage points. This system is characterized by the following: The small amount of water used in it, and it is ideal for small and medium agricultural lands.

• Solar sprinkler irrigation system

Here the farmer uses pumps To run Sprinklers distribute water in a spray form over the crops. This system has many advantages, such as: it is suitable for large crops and pastures, and it also consumes more water than drip.

• Solar surface irrigation system

Water is pumped into open channels that directly irrigate the land. This system is characterized by its simplicity and low cost.

• Solar Mist Irrigation System (Suitable for Greenhouses)

Uses micro pumps to spray a water mist to humidify the air and plants, is ideal for modern greenhouses, and maintains a suitable climate for plants Sensitive.

In conclusion, solar power irrigation system are modern systems that facilitate the farming process for farmers, as these systems use solar energy, which is converted into electrical energy that is used in irrigation.
