2.2kW Solar Water Pump Inverter in Philippines

Project Introduction

In July 2019, the SI22 series 1.5kW solar water pumping system was successfully installed in a village in the Philippines. The project was invested by the local government for irrigating rice fields.

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 3000kW solar array，2.2kW pump inverter and 2.2kw pump and provides 3m³/h water for irrigation.
