Look for SEANZ (Sustainable Energy Association of New Zealand) accreditation, which means an installer works to a formal code of conduct, and ask what panel and inverter brands they use and what warranty backs the system. Reputable Hamilton installers typically supply named-brand panels rather than unbranded imports.
From September 2026, electricians doing grid-tied solar work need to hold the Electrical Workers Registration Board's Endorsed Mains Parallel Generation Systems registration as their licence comes up for renewal, so it's worth asking whether your installer's electrician already holds this. A good installer also handles the paperwork with your lines company and retailer to get your system connected, and from July 2026 major retailers must offer time-of-use pricing and pay rebates for peak-time solar export.
Cost depends on system size, roof type and panel/inverter brand, so it varies significantly between homes. The best way to get an accurate price is to request on-site assessments and written quotes from two or three SEANZ-accredited installers and compare like-for-like system specifications.
Since October 2025, most residential rooftop solar installations under 40 square metres per roof are exempt from needing a building consent under MBIE's rules, which has simplified and sped up the process for typical home installs. Larger or unusual installations may still need consent, so check with your installer.
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 solar exported during peak times, which makes export more valuable than under older flat-rate buyback schemes.
Yes. Hamilton receives around 2,000 sunshine hours a year on average, and the city's flat terrain means most roofs get consistent solar exposure with few shading issues, making it a solid location for solar generation year-round.
A battery lets you store daytime solar generation to use in the evening rather than exporting it, which can increase self-consumption, but it adds meaningfully to upfront cost. Whether it pays off depends on your household's evening power use and the export rates your retailer offers, so it's worth asking your installer to model both options.
