John Smith wanted a reliable, plug and play irrigation solution to water his lawn and garden using solar power. He wasn’t interested in batteries or complicated controllers — he needed a system that could run directly from a single solar panel, handle small sprinklers, and operate without constant monitoring or resets.
Â
Solar Centrifugal Pump Installation Environment
John needed a solar powered irrigation pump for a small outdoor installation where grid power was unavailable. The system was set up to run one to two standard sprinklers, with an installation head of approximately 15 ft (5 m) and a horizontal pipe run of about 75 ft (25 m).
The pump was installed in a surface water source and required fully automatic operation without batteries. Thanks to its centrifugal design, the pump starts automatically when sunlight is sufficient and shuts down safely under low-light conditions, eliminating the need for manual resetting or additional controllers.

Solution: Flowatt 36V 0.5HP Solar Centrifugal Pump
For John’s off grid garden irrigation system, the Flowatt 36V 0.5HP Solar Surface Water Pump proved to be the perfect match. This solar pump without battery features a vortex impeller design, ensuring steady water flow while reducing the risk of clogging from minor debris.
As a dedicated solar irrigation solution, it delivers consistent performance for lawns and small agricultural plots—completely eliminating the need for expensive battery maintenance or complex inverters. Furthermore, this solar pump without battery setup is optimized for peak sunlight hours, making it the most sustainable and cost-effective choice for John’s 75 ft water run.
Recommended Solar Panel Setup
To power this Flowatts 36V 0.5HP 1 inch Solar Surface Water Pump efficiently, we recommend pairing it with the most efficient solar power source (sold separately). For John’s setup, the optimal configuration included:
- Panel Voltage (Vmp): 36 V
- Open Circuit Voltage (Voc): 44 V
- Unit Panel Power: 540 W
- Panel Quantity: 1 PC
This configuration provides stable DC power to the pump motor, enabling consistent water flow for irrigation without the need for batteries. It ensures John’s garden receives reliable water for sprinklers and small agricultural use, even in off the grid conditions.
How Does a Solar Centrifugal Pump Work?
Designed for simple, off grid irrigation without batteries, a solar centrifugal pump operates directly on sunlight to deliver consistent water flow with minimal maintenance. Here’s how the system works in practice:
- A solar centrifugal pump like this works by converting sunlight directly into mechanical energy to move water:
- Solar panel generates DC power — feeding electricity to the pump motor directly.
- Centrifugal impeller spins — pushing water outward and creating steady flow.
- Vortex pump design — reduces clogging and allows the water pump to handle minor debris from surface water.
- Automatic operation — the pump starts when sunlight is sufficient and stops safely during low light, no resetting required.
- This makes it an efficient, easy-to-use solar irrigation pump for lawns, gardens, and small agricultural applications.
