4kW Solar Water Pump Inverter in Johannesburg South Africa

Project Introduction

In February 2021, the Veichi 4W solar pump system was successfully installed on a farm in South Africa.

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 4kW solar array，4kW pump inverter and 4kw pump and provides 5m³/h water for irrigation.
