Solar gets a boost as government clears the way for more rooftop panels
Homeowners looking to harness the sun will soon find it easier to install rooftop solar panels, thanks to a series of regulatory changes announced by the Government.
The changes include expanding the permitted voltage range on New Zealand’s electricity networks from +/-6% to +/-10%, removing the need for building consent to install solar on existing homes and halving the consent processing time for new homes with solar systems to 10 working days.
These “common-sense changes” are aimed at removing roadblocks and accelerating solar uptake across the country, according to Energy Minister Simon Watts and Building and Construction Minister Chris Penk.
“New Zealand’s residential uptake of rooftop solar is lower than many other countries. This Government wants to change that so more Kiwis can generate, store and send their own electricity back to the market,” Mr Watts said. “Modelling suggests this change could boost solar investment and overall generation by a whopping 507 GWh through increased solar connections.”
The expanded voltage range is designed to future-proof the electricity grid by better managing the growing flow of energy from rooftop solar and electric vehicles. Meanwhile, the streamlined consenting process should reduce inconsistency across councils and make solar more accessible for those building new homes.
“We need the right incentives in place to make rooftop solar a realistic option for Kiwis,” Mr Penk said. “These changes will save Kiwis time and money and support our transition to more sustainable homes.”
Finance options for solar – and how green lending can help
As solar becomes easier to install, more homeowners are turning to green loans and sustainability-linked finance to help fund the upfront costs.
Green loans are designed specifically for environmentally friendly upgrades, such as installing solar panels, adding battery storage or improving a home’s energy efficiency. Many lenders now offer lower interest rates on these types of loans, in recognition of the long-term savings and environmental benefits.
Some banks also offer top-up lending or bundled options for those adding solar to a home purchase or renovation project. These packages can make it easier to align your finance with your values – and in today’s cost-of-living environment, every bit of energy saving counts.
While solar panels require an upfront investment, they can reduce ongoing electricity bills, improve energy independence and even add value to your property. That’s especially appealing when households are looking for ways to cut costs without compromising their lifestyle.
