Before you hire

Solar panel quality and installer experience vary significantly. Ask for the payback period calculation based on your actual power bills, check whether they use tier-1 panels, and confirm what happens to your warranty if the installer goes out of business.

Before you hire a solar installer in Dunedin

Drawn from 134 customer reviews collected for this page. The first answer is what it costs.

What does a solar installation typically cost in New Zealand? expand_more

A standard 5kW to 6.6kW residential solar system costs between $10,000 and $14,000 installed, covering panels, inverter, and labour. Larger systems or those requiring battery storage push costs toward $20,000 or beyond, since battery units add several thousand dollars on their own. Roof complexity, shading, and inverter brand all affect the final price, with difficult roof angles requiring more labour and specialised mounting hardware. There is no government subsidy for residential solar in New Zealand as of 2025, so get at least three quotes and ensure each one is based on your actual power usage, not a generic household estimate.

Full solar installation cost guide, with sources

How do I check if a solar installer is properly accredited? expand_more

Every installer connecting a solar system to the grid must hold a current Registered Electrician licence issued by the Electrical Workers Registration Board (EWRB), and you can verify this through the public register at ewrb.govt.nz before signing anything. Beyond that legal minimum, look for membership of SEANZ, the Sustainable Energy Association of New Zealand, whose members are required to meet competency and conduct standards specific to the solar industry. Asking whether the installer holds SolarCert certification is a useful extra step, as it confirms specialist solar PV knowledge rather than just a general electrical licence. Installers who coordinated grid connection and retailer approvals on behalf of customers, as several Dunedin reviewers noted, are demonstrating exactly the kind of end-to-end competence these credentials are designed to signal.

How accurate are the payback period and savings estimates I'm being given? expand_more

Payback estimates in New Zealand for a typical 5kW to 10kW system range from 8 to 12 years under realistic conditions, but that figure shifts significantly depending on how much generation you consume directly rather than export. Export buy-back rates from most retailers sit around 8 to 17 cents per kWh, while you pay 28 to 35 cents to import power, so households that are home during the day and run appliances through the day will see much better returns than those who export most of their generation. Adding battery storage often pushes payback beyond 15 years given current battery costs, so treat any estimate below that with scepticism unless the installer can show the assumptions clearly. One local installer was noted by reviewers for providing upfront solar generation and cost estimates that proved accurate over time, which is the benchmark to hold others to.

What are the warning signs of a solar installer you shouldn't hire? expand_more
  • –An installer who fails to visit your property in person before quoting is likely working from assumptions that may not match your roof, shading, or switchboard situation.
  • –Vague or shifting timelines with no proactive updates are a red flag, since well-run installations involve coordinating third parties like lines companies and retailers, which requires active management.
  • –No clear plan for post-installation support, including who to contact if the system or monitoring app has issues after handover, is a serious gap.
  • –A salesperson who is knowledgeable and responsive but hands the job to an installation crew with no briefing or continuity increases the risk of details being missed on site.
  • –Reluctance to provide an itemised quote makes it hard to compare prices or understand what you are paying for, and leaves you exposed if something is excluded.
  • –One negative review in this category described an installer who failed to follow instructions and did not honour commitments, which points to checking recent reviews carefully before committing.
What should you ask before hiring a solar installer? expand_more
  • –Ask whether they hold current EWRB registration and can provide their licence number, and whether they hold SEANZ membership or SolarCert certification.
  • –Ask what assumptions underpin the savings estimate, specifically the export buy-back rate used, the assumed percentage of self-consumption, and the annual panel degradation rate applied.
  • –Ask who handles grid connection applications, retailer paperwork, and lines company approvals, and whether those are included in the quoted price.
  • –Ask whether app setup, a walkthrough of the monitoring system, and user training are included as part of the installation handover, since several reviewers specifically valued this.
  • –Ask what the workmanship warranty covers and for how long, separate from the manufacturer warranties on panels, inverters, and batteries, which are different documents with different claim processes.
  • –Ask for a fixed or capped quote rather than an open estimate, since at least one Dunedin reviewer confirmed their final bill matched the original quote exactly, which is the outcome to aim for.
