18kW Solar Water Pump Inverter in Domingo, Dominica

Project Introduction

The system pumps water from wells to irrigate cornfields. It runs automatically without manual monitoring and batteries. The total water head is about 50 meters, and the average daily flow can reach 30 cubic meters.

The challenge:

The problem of energy and water sources is one of the most important issues many countries are faced with. Around more than 30% agricultural pumps are not available to connect with grid electricity due to poor power facilities. And 50% farms cannot get well irrigated because of poor water conservancy infrastructure.  Nowadays the cost of diesel is rapidly increasing，so the cost of maintenance on diesel generator pump system is very high. It is urgent and important to find a sustainable way for agricultural irrigation.

The solution:

Solar powered water pump technology is a very good solution to agricultural irrigation. The system consists of 19kW solar array，18.5kW pump inverter and 15kw pump and provides 20m³/h water for irrigation.
