Look for installers who are members of SEANZ (the Sustainable Energy Association of New Zealand), which sets a baseline code of conduct for the industry. Ask what panel and inverter brands they use, and get the warranty terms in writing - reputable installers will be upfront about product warranties as well as their own workmanship guarantee.
From September 2026, electricians doing grid-tied solar work need the Electrical Workers Registration Board's 'Endorsed Mains Parallel Generation Systems' registration to renew their licence, so it's worth asking whether your installer's electricians already hold this. A good installer will also handle the paperwork for connecting your system to the local network and your retailer on your behalf.
Costs vary by system size, roof type and battery inclusion. Get quotes from a couple of the installers above, who can size a system to your household's power use and roof, rather than relying on a single generic estimate.
From October 2025, most residential rooftop solar installations under 40 square metres per roof are exempt from needing a building consent under MBIE's rules. Your installer can confirm whether your specific project qualifies.
Unused solar power is 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 current export rates.
Yes - Taranaki is regularly cited as one of New Zealand's sunniest and windiest regions, which supports strong solar generation across the year, though exact sunshine-hour figures vary by source and measurement site.
A battery lets you store daytime solar generation for evening use rather than exporting it at a lower rate, which can be worthwhile if you use most of your power outside daylight hours. Several installers on this list, including Empower Electrical Taranaki, specialise in battery and off-grid systems and can advise whether it makes sense for your household.
