JENENSERIES 500W DC Solar Water Pump (48V)
Overview: This 500W, 48V DC solar pump is designed for deep-well applications with a 3-inch diameter and a max head of about 120 meters (393 feet). It supports a high flow rate around 1.8 m³/h (approximately 7.9 GPM) and comes with an MPPT controller to optimize energy use from solar panels in farm, garden, home, or industrial settings. The 304 stainless steel submersible design enhances durability and can be paired with batteries for on-demand pumping. An intelligent water shortage sensor automatically stops the pump when water is unavailable, reducing wear and energy waste.
Key features include: 3-inch bore, MPPT controller compatible with a wide PV voltage range (42-100V open circuit), and a stainless-steel build for long-term use. The kit’s emphasis on energy efficiency makes it suitable for agricultural operations that rely on sunny-day productivity. For farm-scale irrigation, ensure your solar array matches the pump’s voltage range and head requirements. Maintenance includes monitoring water source levels to leverage the sensor-based protection effectively.
Tuhorse 2″ 370W Solar Submersible Deep Well Pump Kit
Overview: The Tuhorse kit pairs a 2-inch pump with a compact 370W solar array and 200 feet of cabling. Textured for agricultural wells, it provides a practical range of flow rates depending on sun exposure, such as roughly 6 GPM at 10 feet, tapering to 1.7 GPM at 100 feet. It is compatible with wells that are at least 2-1/2 inches in diameter and includes a 1/2″ NPT discharge. This package is well-suited for mid-range irrigation and livestock watering where a compact footprint and simple installation matter. Users should plan for peak sun conditions to maximize daily output.
Performance notes: The kit’s performance scales with sun hours and well depth. For best results, pairing with battery storage or a robust controller can stabilize output during fluctuating cloud cover. Ensure your pump and controller wiring is appropriately rated to handle cumulative run times and the well’s static water level to avoid cavitation or overheating.
ECO-WORTHY Solar Well Pump Kit (100W)
Overview: This kit centers on a 100W solar panel paired with a deep-well water pump intended for off-grid irrigation and small-scale farm use. With a max lift of up to 230 ft and a flow around 1.6 GPM, it is designed for straightforward, battery-compatible operations. It is flexible enough to run directly from solar panels or with a 12V battery and controller for more stability. Maintenance emphasizes keeping solar panels free of shade and dust to preserve energy capture, as shading can significantly reduce output. This kit is a compact choice for small plots or garden irrigation in remote farm settings.
Considerations: Battery compatibility increases system resilience during cloud cover. However, direct-sun operation minimizes components and potential points of failure, reducing total cost. For larger plots, consider scaling with higher-wattage panels or adding additional pumps to match water demand and irrigation layouts.
PWS Pump With Solar — 3-Year Warranty (540W)
Overview: This high-capacity 540W deep-well system is built with a 3-inch stainless steel 316 pump designed for borehole use with a 390 ft head and about 9 GPM flow. It supports battery backup, enabling pumping on demand when solar is insufficient. The system includes sensors to prevent overflow and under-supply by auto-switching off if the header tank is full or the water source is depleted at the inlet. Its robustness makes it suitable for agricultural irrigation, greenhouse watering, and livestock operations that require reliable, automated water delivery across variable weather.
Key advantages include durable stainless steel construction, a strong lift, and sensor-driven automation. Prospective buyers should match panel capacity and storage to the pump’s head and flow to avoid energy waste and ensure the system can meet peak irrigation demands during sun-rich days.
JENENSERIES 270W DC Solar Pump (24V)
Overview: This 270W, 24V DC solar pump features a 3-inch well diameter with MPPT controller for farm, garden, home, pool, or industrial use. It provides a max head of about 262 ft and a flow near 7.9 GPM, making it suitable for mid-depth wells and irrigation tasks requiring a balance of lift and volume. The 304 stainless steel submersible design supports long-term operation, and the intelligent water shortage sensor protects the system from running dry. Like the 500W model, it also accommodates battery compatibility for on-demand pumping.
Considerations: Ensure your solar array provides the appropriate voltage range and current to match the pump’s MPPT controller. This model is effective for smaller farms or remote plots where land and water source conditions create moderate pumping needs with a focus on reliability and longevity.
Buying Guide for Solar Irrigation Pumps
- Water source and lift: Estimate well depth and required head (lift). Higher heads demand larger pumps and/or more solar capacity.
- Flow needs: Determine daily irrigation volume. Moderate-to-high flow pumps suit larger plots or greenhouses, while smaller plots can rely on lower-capacity units.
- Solar array sizing: Match panel wattage to pump power and peak sun hours in your location. MPPT controllers improve efficiency under variable sunlight.
- Battery compatibility: Battery storage can stabilize pumping during cloudy days or nighttime, but adds cost.
- Durability and materials: Stainless steel submersible pumps resist corrosion and improve longevity in farm environments.
- Automation features: Water shortage protection and sensors help prevent damage and water waste.
- Maintenance: Regular cleaning of solar panels and inspection of seals, wiring, and connectors extend system life.
- Scalability: Consider modular kits or multiple pumps to cover irrigation zones or different crop cycles.
These solar pumping options illustrate a range of capacities and configurations for agricultural use. When selecting, align the pump’s head, flow rate, and energy management with your crop type, field layout, and available sunlight. A system that combines a reliable pump with an appropriately sized solar array—and optionally a battery or controller—offers consistent, sustainable irrigation across seasons.
