Look for installers accredited with SEANZ (the Sustainable Energy Association of New Zealand), which requires members to work to a code of conduct covering business practice and installation standards. Ask what panel and inverter brands they use and what warranty applies to the panels, the inverter and the workmanship separately — these can differ significantly between suppliers.
From September 2026, electricians doing grid-tied solar work will need the Electrical Workers Registration Board's Endorsed Mains Parallel Generation Systems registration when renewing their licence, so it's worth asking whether your installer's electricians hold this. A good local installer will also handle the network-connection paperwork with your lines company and retailer on your behalf, including the new time-of-use pricing and peak-export rebates major retailers must offer from July 2026.
Cost depends on system size, roof type and how much of your own power use you want to offset, so it's worth getting quotes from two or three local installers before deciding. Ask each for an itemised quote covering panels, inverter, installation and any switchboard upgrade needed.
Since October 2025, MBIE's building consent exemption means most residential rooftop solar installations under 40m² per roof no longer need a building consent, which has made it faster and cheaper to install solar on an existing home. Larger systems, or installs on heritage or unusual roof structures, may still need consent, so check with your installer.
Excess power you generate and 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 during peak times, so it's worth checking your retailer's current export rate when comparing solar quotes.
South Canterbury sits in the lee of the Southern Alps and generally enjoys a drier, more settled climate than much of the West Coast, which is favourable for solar generation. A local installer can give you a site-specific yield estimate based on your roof's orientation and any shading.
A battery lets you store excess daytime generation to use in the evening rather than exporting it to the grid, which can be worthwhile if your household uses more power outside daylight hours. It adds meaningfully to the upfront cost, so it's worth asking your installer to model the payback with and without one for your specific usage.
