We keep seeing examples of farmers taking energy into their own hands, saving money and increasing their resilience and Tim Campbell of Ernest Energy is one of the people helping them do it down south.
At Clover Milk Dairies in Hedgehope, his company has installed a 75kW array on some unproductive land and it's in a relatively unique configuration.
"It was a hedgerow that needed to be knocked down, so essentially we've used that land quite nicely between the main cow lank and main tanker track."
The hot water cylinders all operate during the middle of the day - something we recommend all homes with solar do - the effluent system is now also used between milkings, and the solar also plays a role when it comes to keeping the milk cool.
While the farm doesn't yet have batteries, they can be added later. But McPherson Dairies down the road has installed 100kwH of battery storage that can charge up on cheap night rates or solar during the day and discharge when milking and for cooling.
Campbell says the solar and battery set up there will take around six and a half years to pay off, including borrowing costs and claiming depreciation on the asset.
"But the resilience piece is the hard part to value."
When Mike Casey bought his house near Cromwell, it came with gas bottles on the side of the home for water and an expensive diesel system for the underfloor heating. He replaced both of them with a Steibel Eltron system and it's been saving him money ever since. As technical manager Bhawesh Singh told him at the Electrify Queenstown conference, there has been a big influx in enquiries from homes looking to get off the molecules and onto electrons.

A new Regulation Ministry reports laid out a potential blueprint to legalise plug-in solar and reduce the time and cost of panel installation. Rewiring Aotearoa CEO Mike Casey shares his thoughts with Andrew Dickens.
The burgeoning demand for solar was also a chance to address a mismatch between the numbers of training opportunities available and young people searching for work, Casey said. "The mums of New Zealand are telling me that there's not enough apprenticeships for their kids and the solar installers of New Zealand are telling me there's not enough trained people."
