Lorentz Solar Water Pump

Lorentz Solar Pump – Reliable, Efficient, and Built for Off‑Grid Performance

The Lorentz Solar Pump is engineered for dependable water delivery in even the most remote locations. Designed in Germany for maximum efficiency and long service life, this pump harnesses the power of daylight to provide a clean, cost effective and maintenance friendly water pumping solution. Whether you’re supplying water for livestock, irrigation, household use, or remote installations, Lorentz delivers performance you can trust.

Built around a high efficiency brushless DC motor and intelligent controller, the Lorentz system automatically optimises output based on available daylight—giving you consistent water flow without the need for fuel, grid power, or frequent servicing.

What are the main benefits of using a LORENTZ solar water pumps?

LORENTZ solar water pumps offer low running costs, quiet operation, long service life and minimal maintenance. They are environmentally friendly, highly reliable and designed to deliver consistent water supply when you need it most.  Typical uses include -

Available Kit Options

1. Standard Kit with Four 100W Solar Panels (400W Total)

The ideal choice for users who want maximum pumping performance throughout the day.

• Best for deeper wells, higher lift requirements, or larger daily water volumes
• Extended pumping hours thanks to increased solar input
• Delivers the strongest flow rate and most consistent performance in variable weather

This configuration is perfect for farms, larger small holdings, and commercial applications where reliability and output are top priorities. 

2. Standard Kit with Two 100W Solar Panels (200W Total)

A balanced, cost‑effective option that still delivers excellent performance.

• Suitable for moderate pumping needs
• Ideal for shallower wells, smaller tanks, or lower daily water demand
• Reduced upfront cost while maintaining Lorentz quality and efficiency

This kit is a great fit for small farms, garden irrigation, and general-purpose water supply.

3. Standard Kit with No Solar Panels

For customers who already have solar infrastructure or prefer to source their own panels.

• Full Lorentz pump and controller system included
• Flexible panel sizing and configuration
• Perfect for integrating into existing off‑grid setups

This option gives you complete control over your solar array while still benefiting from Lorentz’s industry‑leading pump technology.
