Look for SEANZ (Sustainable Energy Association of New Zealand) accreditation, which signals the installer has agreed to an industry code of conduct and is recognised by major bank green-loan schemes. Beyond that, ask what panel and inverter brands they use and what warranty backs both the equipment and the installation workmanship — reputable installers will name their brands and warranty terms up front rather than being vague about them.
Because Wellington's terrain and wind exposure make correct system design especially important, favour installers with their own in-house electricians rather than ones who subcontract the work out. From September 2026, electricians doing grid-tied solar work will also need to hold the Electrical Workers Registration Board's Endorsed Mains Parallel Generation Systems registration on licence renewal, and from July 2026 major electricity retailers must offer time-of-use pricing and pay rebates for peak-time solar export — a good local installer should be able to explain how both of these affect your system and your retailer paperwork.
Costs vary by system size and installer, but a typical residential system runs from roughly $10,000 to $16,000 installed, with battery storage adding several thousand dollars more. Get quotes from at least two or three verified local installers before deciding.
From October 2025, most residential rooftop solar installations under 40m² per roof are exempt from needing a building consent under MBIE rules, which has made installing solar in Wellington faster and cheaper for most homeowners. Larger or more complex installs may still require consent, so check with your installer.
Excess power you generate but don't use gets exported back to the grid. From July 2026, major electricity retailers are required to offer time-of-use pricing and pay rebates for solar exported during peak times, so it's worth checking your retailer's export rates when comparing plans.
Wellington is windier and gets less sunshine on average than northern New Zealand cities like Auckland or Nelson, so solar systems here generally need careful sizing and orientation to perform well. It's still a viable location for solar, but a good local installer should design around Wellington's specific weather rather than using a one-size-fits-all approach.
A battery lets you store daytime solar generation for use in the evening rather than exporting it to the grid, which can be worthwhile if your household uses more power at night. Whether it pays off depends on your usage pattern and the export rebate rates now required from retailers from July 2026, so it's worth asking your installer to model both scenarios before deciding.
