Solar Powered Watering System

This solar watering system was featured at our members meeting in November 2015 and it is so easy to assemble.

Solar energy as a power source for water pumping is an ideal solution where water is required when the sun is shining, or where it can be stored in a high location (eg in a header tank). The main components of a greenhouse solar pump system include:

  • Solar Panel
  • Solar regulator
  • Battery 12v
  • Pump 12v
  • Timer 12v
  • Cables & Connectors

The picture on the left is the heart of the solar system which is located neatly under the house for easy access, the barrels contain ready to use nutrient solution which is pumped to the glasshouses when required. Next there is a battery which stores electricity for when the sun isn’t shinning and connected to it is timer and regulator for precise feeding times.  The solar panel on the roof powers the system.


The nutrient is piped to the glasses house where they are delivered to the plants via Autopot valves so there is no waste or run off. This is a non recirculating system.

System Configuration

Simply put, all you need to determine is the following three parameters:

  • geographical location
  • required maximum head (total vertical lift)
  • required water quantity per day
