Solar Agriculture and Solar Farm Irrigation System Application Guide

Advancing agricultural automation drives rising demand for off-grid solar power systems on farms, enabling energy-independent operations, reducing grid reliance, and supporting sustainable practices with clean energy solutions.

The Current Status and Future of Solar Agriculture and Solar Farm Irrigation System

The global off-grid agricultural and solar farm power system market is expanding rapidly, with a market size exceeding US$12 billion in 2023 and an annual growth rate of approximately 15%. Developing countries (such as those in Africa and the Asia-Pacific region) are the primary growth areas due to significant electricity shortages, while developed countries are accelerating their expansion through policy subsidies. It is projected that the market size will surpass 30 billion USD by 2030, with a CAGR exceeding 12%. Technological innovation, climate policies, and cost reductions are the core drivers of this growth; however, initial investment and operational barriers continue to hinder widespread adoption in certain regions.

The Impact of Off-Grid Solar Energy Storage Power Generation Systems on Farms

The widespread adoption of solar power systems marks a transformative era in modern agriculture, enabling numerous farms to achieve complete energy independence through off-grid operations. By integrating photovoltaic arrays with advanced energy storage solutions, agricultural enterprises can maintain 24/7 operation of critical infrastructure including climate-controlled greenhouses, automated irrigation systems, intelligent lighting networks, refrigerated storage facilities, and on-site processing lines. This renewable energy paradigm not only replaces increasingly expensive grid electricity with cost-free solar power but also eliminates emergency fuel expenditures for backup generators during outages. Consequently, farm operators are experiencing sustainable profit growth through optimized energy expenditure structures, while establishing resilient, eco-friendly production models immune to energy price fluctuations.

System Design and Configuration Plan

Typical Application Scenarios

Irrigation System Power Supply

Requirements Analysis
Pump power (e.g., 0.5 kW–10 kW), daily operating hours (4–8 hours), seasonal load fluctuations (high load during dry season).
Key points of the plan
  • Use a 12kW hybrid inverter to drive a deep well pump and supply power to all circuits in the entire irrigation pipeline.
  • Battery capacity needs to cover periods without sunlight (such as nighttime irrigation, where some crops require nighttime lighting). It is recommended to use lithium iron phosphate batteries with a high cycle life.

Greenhouse/farm temperature control

Requirements Analysis
Constant temperature equipment (fans, heaters), humidity control, CO₂ replenishment systems, etc. operate around the clock.
Key points of the plan

On-site Processing

Requirements Analysis
Flexible cleaning machines, high-pressure cleaning machines, vibrating screens, optical sorting machines, weighing and packaging lines, etc.
Key points of the plan
  • Select an inverter with high overload capacity that can withstand motor start-up shocks.
  • Design with 1.2 times redundancy based on peak load (e.g., 20kW peak load → 24kWh energy storage).
  • Prioritize south/equatorial orientation, adjust tilt angle according to local latitude to maximize daytime power generation.

Cold Storage Warehousing

Requirements Analysis
Cold storage compressors, pre-cooling tunnels, constant temperature and humidity controllers, packaging area lighting. Continuous 24-hour operation, sensitive to temperature and humidity fluctuations (±1°C error may result in losses).
Key points of the plan
  • Choose a pure sine wave inverter (to avoid harmonic interference with precision temperature control equipment). We recommend our hybrid inverter, which supports seamless switching between mains power, battery power, photovoltaic power, and chemical generators to ensure continuous power supply.
  • Pair it with our large-capacity deep-cycle battery (customization available).

System Configuration Guide

Capacity calculation formula

Photovoltaic capacity formula
Total photovoltaic power (kW) = Daily electricity consumption (kWh) / (Local average peak sunshine hours per day × System efficiency 0.8)
Battery capacity formula
Battery capacity (kWh) = Daily power consumption × Number of days of power supply required / (Depth of discharge DOD × Inverter efficiency 0.9)
