ENERGY: Case study - Solar pumping: economic and environmental rewards

The installation of a solar diesel hybrid irrigation bore pump on a 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 Gill and his family decided to install a solar diesel hybrid system at one of the pump sites on their Narromine farm.
