1.5kW Solar Water Pump Inverter in Kandahar, Afghanistan

Project Introduction

In recent years, the main driver of Afghanistan's economic growth has been the agricultural sector. The local government sector has also given high priority to investment in agricultural infrastructure development.

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 1kW solar array，1.5kW pump inverter and 1.1kw pump and provides 2m³/h  water for irrigation.
