We don't accept payment in exchange for a place in the Top 5. Featured placements are separate and always clearly labelled. Rankings may change over time as businesses evolve.
Start by checking SEANZ (Sustainable Energy Association of New Zealand) accreditation — it signals an installer meets industry standards for design, safety and consumer protection. Ask what panel and inverter brands they use, and get the manufacturer's product warranty (typically 10-25 years on panels) in writing alongside the installer's own workmanship warranty, which is often the more important number if something goes wrong.
From September 2026, electricians doing grid-tied solar work need Electrical Workers Registration Board 'Endorsed Mains Parallel Generation Systems' registration to renew their licence, so it's worth asking whether your installer's electricians hold this. Since October 2025, most residential rooftop solar installs under 40m² per roof no longer need a council building consent, which has sped up installs, but your installer should still handle the paperwork for connecting your system to the local network and your electricity retailer.
Costs vary with system size, roof type and panel/inverter brand, so get quotes from at least two or three of the installers above rather than relying on a single online estimate. Ask each installer for an itemised quote covering panels, inverter, mounting, electrical work and any battery, so you're comparing like for like.
Since October 2025, most residential rooftop solar installations under 40m² per roof no longer require a building consent from the Dunedin City Council, which has made installs faster and cheaper. Larger systems, unusual roof structures, or heritage-listed properties may still need consent, so check with your installer.
Excess solar 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, so it's worth reviewing your retailer's export rates once your system is connected.
Dunedin gets around 1,600 hours of sunshine a year on average, which is lower than sunnier northern New Zealand centres, but the city's long summer daylight hours and consistently high power prices still make well-designed systems worthwhile over their lifetime. A reputable local installer will size your system realistically for Dunedin's conditions rather than promising northern-NZ output.
A battery lets you store daytime solar generation for use in the evening, which matters most if you're often out during the day or want backup power. Several of the installers above, including Think Solar Dunedin and Future Energy Dunedin, are certified Tesla Powerwall installers and can advise whether a battery makes financial sense for your household's usage pattern.
