Check whether an installer is a SEANZ (Sustainable Energy Association of New Zealand) accredited member, and ask what panel and inverter brands they use and what warranty backs both the equipment and the installation workmanship. Since October 2025, most residential rooftop solar installs under 40m² per roof no longer need a building consent, which speeds up the process, but the electrical connection work still needs to be done properly by a registered installer.
From September 2026, electricians carrying out grid-tied solar work need to hold the Electrical Workers Registration Board's Endorsed Mains Parallel Generation Systems registration as their licences come up for renewal, so it's worth asking whether your installer's electricians already hold this. A good installer should also handle the paperwork with your lines company and retailer to get your system connected. From July 2026, major electricity retailers must offer time-of-use pricing and pay rebates for solar exported at peak times, so ask how your installer sizes a system to make the most of that.
Cost depends on system size, panel and inverter brand, roof type and whether you add a battery, so it varies significantly between properties. Get quotes from at least two or three of the installers above and compare on equipment, warranty length and installer accreditation, not just headline price.
Since October 2025, most residential rooftop solar installations under 40m² per roof no longer require a building consent under an MBIE exemption. Larger or more complex installs, or those on heritage buildings, may still need consent, so check with your installer or Napier City Council.
Excess power you generate but don't use is exported back to the grid. From July 2026, major electricity retailers are required to offer time-of-use pricing and pay rebates for power exported at peak times, so it's worth checking your retailer's current export rates when comparing solar quotes.
Yes. Napier records around 2,250 sunshine hours a year, among the highest of any New Zealand city, giving solar systems strong output potential across most of the year.
A battery lets you store daytime solar generation to use in the evening, which can increase your self-consumption and reduce reliance on grid power at peak pricing times. Whether it pays off depends on your household's power use pattern and the battery's upfront cost, so ask your installer to run the numbers for your specific situation.
