As the author Kristy Hoare concludes: "Yes, solar and battery systems are a significant investment, but they’re also a ticket to long-term energy independence and peace of mind. With low-interest loans from major banks, more Kiwis are taking the leap into renewable energy without the immediate financial pinch. Ultimately, investing in solar is about more than just the numbers. It’s about taking control of your energy future, contributing to a cleaner environment."

Rewiring Aotearoa CEO Mike Casey was pleased to see the prices matching up closely to its own estimates and says it's always smart to get a few quotes to compare. 

"Every home is different, but most homes are similar so it's good to get a ballpark figure. If you've got a difficult roof, or you need some other upgrades, you can expect to pay more but almost everyone we talk to who goes for it thinks it's a good decision."

The only point of contention was around battery prices and the expectation that they won't drop much this year.

"With the precipitous declines we're seeing from some manufacturers, we believe they will also be dropping in price rapidly for customers - and this is also likely to have an impact on the price of EVs."
