Before you hire a solar installer in Napier and Hastings
Drawn from 201 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 falls between $10,000 and $14,000 installed, covering panels, inverter, and labour. Larger systems up to 10kW can reach $20,000 depending on roof complexity, shading, and inverter brand. Adding battery storage pushes costs higher still, often adding $8,000 to $15,000 to the base system price. No government rebate exists 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 before signing anything at ewrb.govt.nz. Beyond the legal minimum, look for membership of the Sustainable Energy Association of New Zealand (SEANZ), which requires members to meet conduct and competency standards, and ask whether the installer holds SolarCert certification, which tests solar-specific knowledge above the basic electrician licence. These credentials matter because your local lines company, such as Unison in Hawke's Bay, will require compliant documentation before approving grid connection, and a poorly credentialled installer can delay or jeopardise that approval. Several Napier-Hastings installers explicitly handle the lines company paperwork as part of their service, which is worth confirming at the quote stage.
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, but that figure depends heavily on how much of the solar generation you consume directly rather than export. Export buy-back rates from retailers currently run around 8 to 17 cents per kWh, while you pay 28 to 35 cents to import, so a household that exports a large share of its generation will sit at the longer end of the range. Ask your installer what self-consumption rate they have assumed in their estimate, and whether the savings projection accounts for your actual daily usage pattern rather than a generic household average.
What are the warning signs of a solar installer you shouldn't hire? expand_more
- –An installer who pushes toward a sale rather than asking how and when you actually use power is designing for commission, not for your payback period.
- –Vague or shifting installation timelines without clear explanations are a sign of poor scheduling and project management.
- –No structured handover covering the monitoring app, export settings, and how to read your new power bill suggests the relationship ends at installation.
- –Slow or no response when problems arise after the system is live is a serious risk, since metering and grid connection issues can take weeks to surface.
- –A mismatch between a polished salesperson and an inexperienced installation crew points to a business that outsources installs without adequate quality control.
- –An installer who is difficult to contact during the process will not become easier to reach once they have been paid.
What should you ask before hiring a solar installer? expand_more
- –Ask whether they hold a current Registered Electrician licence through the Electrical Workers Registration Board (EWRB) and whether they are a member of the Sustainable Energy Association of New Zealand (SEANZ).
- –Ask what self-consumption rate and export buy-back rate underpin the savings estimate, and whether the payback calculation reflects your actual usage pattern and hours at home.
- –Confirm whether app setup, monitoring walkthrough, and an explanation of your new power bill structure are included as part of the installation handover.
- –Ask who handles post-installation warranty claims: whether it is the installing company directly or a third-party manufacturer, and what the response time commitment is.
- –Clarify the difference between the workmanship warranty the installer provides and the separate product warranties on panels, inverter, and battery, as these can vary significantly between brands.
- –Ask whether the installer manages the lines company connection approval and metering change with your power retailer, or whether that is left to you.
