Before you hire
Whether you use a dedicated solar power company or an electrician who installs solar panels, 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 South Auckland
Drawn from 199 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 system costs between $10,000 and $14,000 installed, covering panels, inverter, and labour. Larger systems with battery storage push that figure toward $20,000 or beyond, and some reviewers reported 40-panel, three-phase setups well above that.
Roof type, shading, and inverter brand all shift the price, and one reviewer noted an unplanned inverter upgrade added 15% to their total mid-project. There is no government rebate for residential solar in New Zealand as of 2025, so the full cost comes out of pocket or through financing.
How do I check if a solar installer is properly accredited? expand_more
Any 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 for free at ewrb.govt.nz before you sign anything. Beyond the legal minimum, look for membership of the Sustainable Energy Association of New Zealand (SEANZ), which requires members to meet competency and conduct standards, and ask directly whether the installer holds SolarCert certification, which tests solar-specific knowledge beyond a general electrician licence.
These credentials matter practically because your local lines company will require the installation to meet grid connection requirements, and a poorly credentialled installer can create approval delays or compliance failures that cost you later. Reviewers who were happiest with their installs tended to work with companies that sent knowledgeable on-site teams, not just a strong salesperson followed by a subcontracted crew.
How accurate are the payback period and savings estimates I'm being given? expand_more
A realistic payback period for a New Zealand residential solar system sits between 8 and 12 years under honest assumptions, though one reviewer reported an estimated six-year payback as a low user with high self-consumption, which is towards the optimistic end of the range. The number hinges on how much of your generation you use directly, since most retailers pay only 8 to 17 cents per kWh for exported power while charging 28 to 35 cents to import it, meaning households that are home during the day and shift appliances to solar hours will see the best returns.
Adding battery storage stretches payback further, often beyond 15 years, because battery costs remain high relative to current NZ retail savings. Before signing, ask the installer to show you the self-consumption ratio and export fraction built into their model, and confirm the buy-back rate used matches what your actual retailer is currently offering.
What are the warning signs of a solar installer you shouldn't hire? expand_more
- –An installer who does not conduct a thorough site visit before quoting may miss constraints like roof pitch, shading, or the need for a wifi extender or larger inverter, leaving you with unexpected costs after deposit.
- –Watch for a strong salesperson backed by a subcontracted installation crew, where quality control drops the moment the salesperson leaves the picture.
- –Poor after-sales support is a clear red flag: one reviewer had a system installed and received no handover or walkthrough after six months, and another reported conductivity near zero on overcast days with no follow-up.
- –Repeated failures of hardware, combined with a company that deflects blame rather than dispatching support, signals a supplier with no meaningful field service capability.
- –Vague or shifting timelines after deposit payment are worth probing before you commit, as several reviewers noted delays that extended well beyond initial estimates.
- –Any company selling DIY solar kits while instructing non-electricians to carry out work that legally requires a registered electrician should be avoided entirely.
What should you ask before hiring a solar installer? expand_more
- –Ask for the installer's Electrical Workers Registration Board (EWRB) registration number and check it at ewrb.govt.nz, and ask whether they hold SolarCert certification or are members of the Sustainable Energy Association of New Zealand (SEANZ).
- –Ask what self-consumption ratio and export buy-back rate underpin the savings estimate, and request a scenario based on your actual household usage pattern rather than a generic calculation.
- –Confirm whether app setup, monitoring walkthrough, and a post-installation handover are included in the contract, since several reviewers found these were left incomplete.
- –Ask who handles warranty claims after installation: whether the installer manages this directly or passes you back to the product manufacturer, and what the workmanship warranty period is separate from component warranties.
- –Ask whether the installation crew are the company's own employees or subcontractors, and check that any connectivity requirements like wifi extenders or 4G dongles are identified and costed before you pay a deposit.
- –Request at least three itemised quotes so you can compare system specifications, not just total price, and confirm the design accounts for your specific roof type and any shading constraints.

How are the top solar installers in South Auckland chosen? expand_more
We build this page from Google Maps results for solar installers in South Auckland. Each one is scored on its public rating and review record. Businesses outside the area, or whose reviews describe a different line of work, are left out, and a business whose main Google category is a different trade is held back until a person has checked what it does. A business whose website no longer resolves and that has had no Google review for six months is treated as dormant and left off the page until either changes. Every category and city is rechecked on a rolling cycle, about every two to three months. A location with a subscribing business is rechecked every month, and the whole page updates with it. See how we rank for the full method.
