2.2kW Solar Water Pump Inverter in Kolkata, India

Project Introduction

In May 2020, the Veichi solar pump system was successfully installed on a farm in the Indian region.

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 1.8kW solar array，1.5kW pump inverter and 2.2kw pump and provides 3m3 /h water for irrigation.
