Installing a solar deep well pump may seem complicated at first, especially if you are unfamiliar with wiring, pipe connections, or solar panel setup. Many users purchase a high-quality solar deep well pump but fail to install it correctly, which can lead to unstable performance, motor damage, reduced water flow, and a shorter service life.
This guide is designed to help beginners install a solar deep well pump safely and efficiently. From checking product parameters to wiring, commissioning, and troubleshooting, every step is explained in a simple and practical way. With the correct installation method, your solar deep well pump can provide a stable water supply for many years while drastically reducing maintenance costs.
Before installing the solar deep well pump, carefully confirm the following technical parameters to ensure system compatibility and stable operation.
1.1 Voltage Compatibility
The voltage of the solar deep well pump must match the solar system configuration. Common models include:
● 24V DC solar deep well pump
● 48V DC solar deep well pump
● 72V DC solar deep well pump
● 110V AC solar deep well pump
● 220V AC solar deep well pump
The voltage of the solar panel, controller, and inverter must match the solar deep well pump to avoid motor burnout.
1.2 Solar Panel Power Matching
The recommended solar panel power should be 1.2–1.5 times the solar deep well pump power.
| Pump Power (W) | Recommended Solar Panel Power (W) | Connection Type |
| 370W | 450W–550W | Series/Parallel based on voltage |
| 750W | 900W–1100W | Series/Parallel based on voltage |
This ensures the solar deep well pump can operate normally even during weak sunlight conditions.
1.3 Head and Flow Rate
The head of the solar deep well pump should be 10%–20% higher than the actual well depth to account for friction loss.
● Well depth: 80m
● Recommended pump head: 90m–100m
1.4 Pipe Diameter
The pipe size should match the outlet diameter of the solar deep well pump (Common sizes: 1 inch, 1.5 inch, 2 inch). Improper pipe size may reduce flow rate or increase pressure loss.
1.5 Waterproof Protection
The pump body features IP68 waterproof protection, allowing the solar deep well pump to work completely underwater. However, the controller and wire connections must remain dry and weatherproofed.

Step 1 – Preparation & Site Inspection
1. Required Tools: Prepare a screwdriver, wrench, wire stripper, waterproof tape, safety rope, and pipe clamps before installing the solar deep well pump.
2. Site Inspection: Clean the well opening from debris. Choose a sunny, unshaded location for the solar panels.
Step 2 – Install Solar Panels
1. Fix the Bracket: Secure the solar panel bracket firmly. The recommended tilt angle is 30°–45° (adjusted by your latitude) to help the solar deep well pump system absorb maximum sunlight.
2. Mount the Panels: Secure the solar panels onto the bracket and tighten all screws.
3. Waterproof Protection: Wrap all outdoor wire joints with UV-resistant waterproof tape to protect the system from rain and moisture.
Step 3 – Install the Solar Deep Well Pump Body
1. Connect the Water Pipe: Attach the delivery pipe tightly to the outlet of the solar deep well pump using heavy-duty clamps.
2. Lower the Pump into the Well: Attach a safety rope to the pump. Slowly lower the solar deep well pump into the well.
3. Important: Never lower the pump by its electrical cable. The solar deep well pump must remain fully submerged, at least 1 meter above the well bottom and at least 1 meter below the dynamic water level.
4. Secure the Pipe: Fix the pipe firmly at the wellhead using a well seal or clamp.
Step 4 – Wiring Connection (Most Important Step)
Correct wiring is critical for the safe operation of your solar deep well pump.
[DC System]: Solar Panels ──> Solar Controller ──> Solar Deep Well Pump
[AC System]: Solar Panels ──> Inverter ──> Control Box ──> Solar Deep Well Pump
● DC Wiring: Connect the solar panels to the control box, then connect the control box to the solar deep well pump. Always double-check that the positive (+) and negative (-) terminals are not reversed.
● AC Wiring: Solar panel $\rightarrow$ Inverter $\rightarrow$ Control Box $\rightarrow$ AC solar deep well pump. Ensure voltage matching before powering on.
Step 5 – Pipe Layout & Valves
Arrange the water pipe to keep it straight and avoid excessive bends. Install a check valve near the wellhead to prevent water backflow, which eliminates water hammer damage to the solar deep well pump.
Step 6 – Commissioning Test
● Final Inspection: Check solar panel stability, wiring correctness, pipe tightness, and pump submersion depth.
● Start the System: Turn on the controller switch and observe the water output of the solar deep well pump.
● Protection Test: Simulating a dry run or testing the low-water sensor ensures the controller cuts power automatically to prevent pump burnout.
Our versatile solar deep well pump is an eco-friendly solution built for various off-grid water needs:
● Household Water Supply: Provides a stable daily water supply for homes and remote cabins in rural areas.
● Agricultural Irrigation: Perfect for farmers utilizing the solar deep well pump for drip irrigation, orchard watering, and greenhouse cultivation.
● Livestock Water Supply: Supplies continuous clean water for cattle, sheep, and poultry farms.
● Remote Off-Grid Locations: Operates independently from the state power grid, making it ideal for desert greening and remote village water projects.
Avoid installing solar panels under strong midday sunlight to prevent accidental shocks or burns.
● Never touch electrical wiring or the controller with wet hands.
● Ensure the solar deep well pump is fully submerged in water before starting the system. Dry running will permanently damage the internal impellers.
● Keep the external solar controller in a well-ventilated, dry environment, protected from direct rain and sunlight.
● Use thicker AWG copper wires if long-distance wiring is required between the solar array and the solar deep well pump.
Q1: Why does the solar deep well pump not start?
A: Possible reasons include incorrect wiring polarities, insufficient sunlight intensity, low water level protection being activated, or the controller switch being turned off. Check the error codes on your smart controller display for precise diagnostics.
Q2: Should solar panels be connected in series or parallel for the pump?
A: Series connection increases voltage, while parallel connection increases current. You must choose the wiring method based on the input voltage requirements of your specific solar deep well pump controller.
Q3: How do I prevent or solve water leakage at the joints?
A: Ensure all pipe joints are tightly secured with professional pipe clamps. Replace any damaged waterproof gaskets and apply sufficient Teflon or waterproof tape around the threads before connecting to the solar deep well pump.
Q4: Can this solar deep well pump work in sandy well water?
A: While our solar deep well pump features sand-resistant components, installing an extra sand filter sleeve around the pump intake is highly recommended if your well has heavy sediment. This prevents premature wear on the impellers.
