RNZ reports on the changes announced by Ministers SImon Watts and Chris Penk that aim to increase the uptake of residential rooftop solar. Rewiring Aotearoa's Mike Casey said the changes to voltage limit would mean more generation, "which is exactly what New Zealand needs… for households in Australia, the average size for solar systems is about 10kWh. In New Zealand it's 5 or 6kWh because solar installations are being built to the size people are allowed to export. This allows for higher levels of solar panels to be on homes. It makes larger systems more economical. When you finance solar panels on your mortgage it probably costs you 13c per kWh - there are many retailers out there buying power off you at more than 13 per kWh. So every piece of power that you don't use in your home that goes back to the grid is actually still in the economic best interest of the household."
He said the more solar that was generated on the rooftops of New Zealand, the more it backed up the hydro system and meant it could be used more as a battery.
"It's a massive win for energy security."
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."
