Solar pumping: the economic & enviro rewards
|

Energy is one of
the fastest growing on-farm costs. The CRDC-funded Improving
energy efficiency on irrigated cotton farms project
found in 2015 that the average direct energy cost was $298 per hectare,
with diesel counting for at least 85 percent.
But not for cotton grower Andrew Gill of Narromine.
The installation of a solar diesel hybrid irrigation bore pump on
his Central West NSW farm has led to big cuts in fuel costs,
greater irrigation efficiencies and a massive reduction in
greenhouse gas emissions.
 Attracted
by the drop in the price of solar panels in recent years and the
prospect of the system paying for itself in less than four years,
Andrew decided to install a solar diesel hybrid system at one
of the pump sites on their Narromine farm at the end of last
year.
The move has led
to a cut in pumping costs from $76/megalitre to $41/ML and slashed
diesel use by between 45,000 and 55,000 litres a year. Over
25 years, that equates to a saving of more than 1
million litres of fuel and a reduction of over 3000 tonnes
in carbon emissions.

------------------------------
While using solar energy for farm water pumping is not new, nor is this the first ever story on the subject it does highlight that this approach is now effectively MAINSTREAM.
And it can work in many many locations around Australia and the world.
Sure capital cost is an issue so a planned approach to financing is important........but it has a big payoff in cost savings and a feel good outcome too. And it works........that has to be a critical issue as well in the present time of 2016!
