DIY Solar Drip Irrigation Kit

If you would like to automate your gravity feed drip irrigation system, it is recommended that you watch the following video.

The kit is for smallholders using gravity feed drip irrigation on a small plot of land. Using the kit, you can automate your drip irrigation system so that water is pumped automatically from your farm pond (or other water supply) to the header tank and all your plants are irrigated
automatically. The DIY Solar Drip Irrigation Kit can be purchased online from the Measured Irrigation Shop.

A waterproof irrigation controller

A double pump with filter,  fittings to connect to 19 mm poly pipe, and 10 metres of waterproof electrical cable

Two float switches

A solenoid valve with fittings to connect to 19 mm poly pipe and 2.5 metres of waterproof electrical cable

A light sensor

 An adjustable dripper

16 waterproof  connectors for electrical wire

How large can the plot be?

The Training Manual assumes that the smallholder has already established a gravity feed drip irrigation system. Provided that the drip irrigation system is already working effectively, you can use the a DIY Solar Drip Irrigation Kit and the MI Six Zone Adaptor to automate the irrigation system regardless of the area of your plot of land.

Depending of the duration of the irrigation event and the power requirements of the pump and the solenoid valves, you may need to upgrade the battery to a larger battery, and you may need to upgrade the solar panel to a larger solar panel.

The flow rate of the solenoid valve needs to be adequate for your irrigation application. The flow rate can be increased by connecting a number of solenoid valves in parallel. Alternatively, you can replace the solenoid valve with a higher flow rate solenoid valve

  • By automating your drip irrigation system you can leave your plot unattended for weeks. This will allow you to become involved in other activities away from the plot; for example, travelling to the market to sell your produce.

  • The kit uses measured irrigation, a method of irrigation scheduling that responds to the prevailing weather conditions. This means that you use much less water without affecting the yield.

  • The depth of the farm pond should be no more than 4 metres.

  • When the automation of your drip irrigation system is complete, you may wish to share your knowledge and experience with others.

The kit does not include:

evaporator

battery

solar panel

These parts should be purchased locally.

Note that a 12V 5A power adaptor may be used
