Solar Irrigation System Design for Farms, Rice Fields and Orchards

Irrigation projects do not fail because solar panels are difficult. They fail when pump voltage, water source, pressure, daily operating time and crop demand are treated as one simple number.

We help match the inverter, pump, PV array, cabinet and accessories around the real field condition: rice irrigation, orchards, vegetables, pond pumping, canal transfer or large farm systems.

Start With the Field

Crop demand changes the equipment path

A solar irrigation system for a small vegetable plot should not be sized like a 200kW farm. We start from crop, source, head and schedule.

Rice Fields

Water volume and stable daily pumping matter more than pressure. SP4 is common when the pump is 380V three phase.

Philippines case

Orchards

Drip and sprinkler lines need flow stability, pipe distance checks and enough PV margin for hot seasons.

Colombia case

Large Farms

High-power pumps need cabinet wiring, protection devices, heat management and service-friendly layouts.

Paraguay case

Selection Matrix

Choose by pump voltage, field size and pressure

The solar pump inverter is the control center of the irrigation system. It converts PV energy into motor output, tracks solar power and protects the pump when water or sunlight changes.

Project Proof

Real irrigation projects with pump and PV data

Case data helps prevent overgeneral sizing. Compare pump power, inverter model, PV array and field type before choosing equipment.

SP4005 solar irrigation inverter for Philippines rice farm

Philippines Rice Farm

SP4005 with 4kW three-phase pump

10 x 550W panels were matched to daytime irrigation demand for rice farming.

Before Quotation

Send field data before ordering the inverter

We can check whether the project should use SP1, SP3, SP4, a cabinet, or a complete accessories package.

Water Source

Well, pond, canal, reservoir or storage tank conditions.

Pipe and Pressure

Pipe distance, lift height, required pressure and outlet layout.

FAQ

Solar irrigation system FAQ

What inverter is best for a solar irrigation system?

Small 220V farms may use SP1 or SP3. Larger irrigation projects with 380V three-phase pumps usually move to SP4. The pump nameplate decides the starting point.

Can irrigation run without batteries?

Yes. Many farms pump during sunlight hours and store water in a tank, channel or reservoir. Batteries are only needed when night pumping is required.

What data is needed for irrigation sizing?

Send pump nameplate, flow demand, total head, field size, crop type, irrigation method, daily working hours, pipe distance, water source and project country.

When should a solar irrigation project use a cabinet?

A cabinet is recommended for high-power pumps, exposed outdoor sites, repeated farm projects or installations that need organized protection devices and easier maintenance.

Can SolarSeeker supply the full irrigation package?

Yes. We can help match inverter, pump, panels, cabinet, sensors, cables, connectors and spare parts for irrigation projects.

Next Step

Planning a solar irrigation project?

Send the pump nameplate, field area, water source, head and daily water demand. We will match the inverter, pump and PV package before equipment is ordered.
