Pivot solar irrigation

Types of pivot solar irrigation

Pivot solar irrigation is a type of irrigation system that waters crops using solar energy. There are three main types of pivot solar irrigations: center pivot, lateral pivot, and linear move.

• Center pivot solar irrigation: This is a circular irrigation system with a pivot point in the center. It works by rotating around the pivot, thereby watering crops in a circular pattern. The center pivot solar irrigation is designed with a metal framework that consists of different spans or sections. These movable sections each have sprinklers or sprayers that enable water to be uniformly distributed over the field as the pivot moves. This type of irrigation is commonly used to water large circular fields. It can cover a vast area efficiently and evenly. Additionally, it is suitable for flat to gently sloping terrains.
• Lateral pivot solar irrigation: Similar to the center pivot, the lateral pivot irrigation system waters crops using solar energy. However, it has a different design and movement pattern. The lateral pivot moves along a linear pivot line, which is perpendicular to the lateral line supplying water. The water is distributed evenly through drop tubes to the ground. The lateral pivot is useful for rectangular fields. It can irrigate long, narrow fields efficiently.
• Linear move solar irrigation: The linear move solar irrigation is a type of irrigation that involves moving parallel pipes over the crop. The pipes are supported by wheels attached to a metal frame. The metal frame moves forward slowly, thereby dragging the pipes over the crops. Water is distributed through nozzles or spray heads along the pipes to the ground. The linear solar irrigation system is often used to irrigate large rectangular fields. It is suitable for fields that are too long for center pivot or lateral pivot systems. Also, the linear move system can work well on flat and gently sloping terrains.

Specification and maintenance of pivot solar irrigations

The following are some key specifications and maintenance requirements of pivot solar irrigation systems, including pivot solar center pivot irrigation system.

Specifications

• System length

The length of the pivot solar irrigation system. The length of the system is usually expressed in feet or meters. It can irrigate a specific area of land based on the system's length, span, and irrigation capacity. This length is determined by the size of the land to be irrigated and other factors.

• Power output

The pivot solar irrigation system's power output is the power provided by the solar panels or other power sources. This is usually measured in watts (W) or kilowatts (kW). The power output determines the ability of the irrigation system to provide water and meet the needs of crop irrigation.

• System capacity

The pivot solar irrigation system's power capacity is the maximum amount of water it can transport and discharge. It is usually measured in liters per hour (L/h) or cubic meters per hour (m3/h). The system's capacity determines the irrigation volume and coverage area, which ensures the water needs of the crops.

Maintenance

Regular maintenance is essential to ensure the efficient operation of pivot solar irrigation systems. Here are some pivotal irrigation system maintenance tips:

• Regular inspection: Operators should regularly inspect the entire pivot solar irrigation system, including solar panels, power systems, pipelines, sprinklers, etc. Check for loose connections, leaks, equipment damage, and other issues. Timely repair and replacement of damaged or faulty parts.
• Solar panel cleaning: Solar panels should be kept clean to ensure maximum power generation. Operators can regularly clean the solar panels to remove dust and debris. This can optimize solar energy absorption and utilization.
• Lubrication: The pivot points and gear mechanisms of the pivot irrigation system need to be lubricated regularly. This reduces friction and wear, ensuring smooth movement of the system and reducing energy consumption.
• Weather protection: In harsh weather conditions, such as strong winds, thunderstorms, etc., take corresponding protective measures for the pivot solar irrigation system. For example, secure the system and components to prevent damage from strong winds.
• Optimize water use: In the process of pivot solar irrigation, pay attention to the adjustment of sprinkler heads and water pressure. Optimize water distribution and avoid water waste. This can be done by avoiding water spraying on non-target areas to ensure efficient use of water resources.

Usage scenarios of pivot solar irrigation

When it comes to the pivot solar irrigation system, it can be used in various agricultural and horticultural applications. These include:

• Farms

The pivot solar system can be used in different farm scales to water crops. It can be used for large-scale field crops like corn, soybeans, wheat, and cotton, or forage crops, including alfalfa and hay. It can also be used to irrigate fruits, vegetables, and nut orchards.

• Ranches

The pivot solar irrigation system is suitable for ranches to provide water for grazing lands, hay fields, and other forage areas. It can also be used to water pasture, raising beef cattle, dairy cattle, sheep, or goats.

• Vineyards

The pivot solar irrigation system is also suitable for vineyards to water grapes used for winemaking. It can help regulate water usage, leading to the production of premium-quality grapes.

• Greenhouses

The pivot solar irrigation system is suitable for greenhouses. It is suitable for providing water for hydroponic systems and containerized crops, and it can also be used for irrigation management to meet the specific water and nutritional needs of plants.

• Nurseries

The pivot solar irrigation system is suitable for nurseries to water field and container-grown trees, shrubs, ornamentals, and other plants. This system can help improve seedling survival and growth.

• Landscaping

The pivot solar irrigation system is also suitable for landscaping. This system is ideal for watering large lawns, parks, and recreational areas. It can also be used in golf courses and sports turf. It ensures uniform water application and healthy plant growth.

• Dry Areas

In addition, the pivot solar irrigation system can also be used in dry areas. It can improve the utilization of water resources and ensure agricultural production under water-scarce conditions.

How to Choose

Several key factors should be considered when choosing a solar irrigation system for commercial applications.

• Solar Panel Quality

One should opt for solar panels that are made of high-quality materials and are well-constructed. This can ensure excellent performance and long-term durability, as well as minimal maintenance.

• Compatibility

It is important to ensure that all components of the solar irrigation system are compatible with one another. This includes solar panels, pumps, controllers, and other elements. This can ensure that the system functions optimally and efficiently.

• Warranty and Support

When choosing a solar irrigation system, one should carefully review the warranties and support options provided by the supplier. Look for suppliers that offer warranties on the system's components, as well as the following support and maintenance services.

• Scalability and Flexibility

Business owners should consider the scalability and flexibility of the solar irrigation system. They may need to expand the system's capacity in the future as their business grows. Choosing a system that can be easily scaled up or modified to meet changing needs can be beneficial.

• Energy Storage

For businesses that need to operate irrigation systems during the night or in low-light conditions, choosing a solar irrigation system with energy storage capabilities is essential. They should consider the type and capacity of the energy storage, such as batteries, and ensure it can meet the irrigation demands.

• Local Climate and Irrigation Needs

It is essential to consider the specific climate conditions and irrigation needs of the business location. Companies should assess the amount of solar energy available in the area and choose a system that can meet the water requirements of the crops. They should also take into account factors such as the type of crops, irrigation methods, and scheduling.
