| Application Scenarios | Modern agricultural irrigation, including power supply for irrigation valve controllers, automatic irrigation systems, water and fertilizer integration equipment, soil moisture monitoring terminals, greenhouse irrigation control, orchard irrigation, and vegetable farm irrigation management. |
| Core Solution | Off-grid Solar Power Supply System (2× 150Wp Solar Panels + 120Ah 12V Battery) |
Solution: Powering Smart Irrigation in Off-Grid Fields
This agricultural irrigation project adopted a power supply system consisting of two 150Wp solar panels and a 120Ah 12V battery to provide a stable off-grid power supply for farmland irrigation valve controllers. The system comprises the dual solar panels, a high-capacity battery, a charge control module, and a 12V power output unit. It can independently handle solar charging, energy storage, and continuous power supply in farmland environments without municipal grid access.
The dual-panel configuration enhances daytime solar energy harvesting and improves charging efficiency in cloudy, rainy, or low-light conditions. Meanwhile, the 120Ah high-capacity battery stores ample energy to meet the power demands of nighttime irrigation, continuous rainy days, and peak irrigation periods. Through this solar power system, irrigation valve controllers can achieve automatic switching, scheduled irrigation, remote control, and smart management, significantly reducing the reliance on manual operations.

Project Implementation: Seamless Integration with Farmland Controllers
The project integrated the solar power supply system with farmland irrigation valve controllers, deploying them near the irrigation control points. The two 150Wp solar panels are responsible for harvesting solar energy and converting it into electricity, while the 120Ah 12V battery stores the power. The charge control module manages the charging and discharging processes to ensure the irrigation controller receives a stable power output.
This solution eliminates the need for a traditional municipal power grid or long-distance cable laying, making it exceptionally suitable for farmlands, orchards, vegetable bases, and facility agriculture areas. Once installed, the irrigation valve controllers can operate automatically according to preset programs, saving the time and labor costs associated with manual valve switching, on-site inspections, and manual operations.
Solution Advantages: Six Core Benefits for Modern Agriculture
1. Dual Solar Panels for Enhanced Charging Capability
The system utilizes a 150Wp × 2 solar panel configuration, offering significantly higher solar energy harvesting capability compared to a single panel. It can quickly replenish power during sunny days and maintain excellent charging efficiency in cloudy, rainy, early morning, or low-light environments, thereby improving overall system stability.
2. 120Ah High-Capacity Battery for Extended Endurance
Agricultural irrigation systems often need to operate not only during the day but also at night or during continuous rainy weather. The 120Ah high-capacity 12V battery stores more electrical energy, satisfying the power needs of nighttime irrigation, continuous rainy conditions, and device standby, effectively reducing the risk of irrigation interruptions due to power shortages.
3. Off-Grid Power Without Municipal Grid Reliance
Many farmland areas have limited grid coverage, making municipal power access expensive and cable laying disruptive to field operations. This solar agricultural irrigation power system adopts an independent off-grid approach, completely independent of the external power grid. It allows for flexible deployment at any irrigation point, significantly lowering grid connection and cable laying costs.
4. Fully Automated Operation to Reduce Labor Costs
Traditional farmland irrigation often requires manual on-site valve switching, equipment status checks, and irrigation schedule adjustments. When paired with an automatic irrigation controller, this solar power system enables scheduled irrigation, automatic valve control, remote monitoring, and smart management, drastically cutting labor costs and boosting irrigation efficiency.
5. Ideal for Large-Scale Agricultural Deployment
For large-scale farmlands, orchards, vegetable bases, and facility agriculture projects, irrigation control points are numerous and widely dispersed. This solar power system can be independently configured for each point or deployed as a standardized power solution, facilitating project replication, batch deployment, and future expansion.
6. Green Energy with Clear Long-Term Returns
The solar power system utilizes clean energy to power irrigation equipment, resulting in exceptionally low operational energy costs, making it highly suitable for long-term agricultural operations. Although it requires a certain upfront equipment investment, it significantly reduces electricity bills, wiring costs, and manual O&M expenses in the long run, offering strong economic and environmental benefits.
Project Value: Driving the Future of Smart Agriculture
By adopting this off-grid solar power system, the agricultural irrigation project effectively solved the challenges of difficult power access for irrigation valve controllers, high wiring costs, and frequent manual operations. The 2× 150Wp solar panel configuration boosted the system’s charging capacity, while the 120Ah 12V high-capacity battery enhanced endurance during nighttime and continuous rainy conditions, enabling fully automated operation of the irrigation system.
Following the project’s implementation, agricultural irrigation management efficiency improved, labor costs decreased, and irrigation control became much more stable and reliable. Furthermore, by reducing reliance on the municipal power grid, the system is highly suitable for large-scale promotion in farmlands, orchards, vegetable bases, and facility agriculture scenarios.
Summary
In 2024, an agricultural irrigation project adopted a power system comprising 2× 150Wp solar panels and a 120Ah 12V battery to provide stable off-grid power for farmland irrigation valve controllers. The dual solar panels ensure continuous charging even on cloudy days, while the high-capacity battery meets the power demands of nighttime and continuous rainy conditions. This setup achieves fully automated irrigation operation, drastically reducing manual labor costs.
This case study serves as a valuable reference for agricultural irrigation control, facility agriculture automation, orchard irrigation management, vegetable farm irrigation systems, and farmland IoT monitoring projects.
