Before you hire

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.

Solar One

Before you hire a solar installer in New Plymouth
Drawn from 135 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. Battery storage adds significantly to that figure, often pushing total costs toward $20,000 or beyond depending on capacity.
Roof type, shading, and inverter brand all affect the final price, with complex or high-pitch roofs requiring additional labour. There is no government rebate for residential solar in New Zealand as of 2025, so you pay the full amount out of pocket or through financing.
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, which you can verify through the publicly searchable register at the Electrical Workers Registration Board (EWRB) website before signing any contract. Beyond that legal minimum, look for membership with the Sustainable Energy Association of New Zealand (SEANZ), which requires members to meet competency and conduct standards specific to the solar industry.
Asking whether an installer holds SolarCert certification is a practical way to gauge specialist solar PV knowledge above the basic electrician licence. Holding both EWRB registration and a recognised credential like SolarCert reduces the risk of installation faults and helps ensure your system meets your local lines company's grid connection requirements.
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, though adding battery storage can push that to 15 years or more given current battery costs. The key variable is self-consumption: import rates of 28 to 35 cents per kWh are far more valuable than export buy-back rates of around 8 to 17 cents, so estimates built on high export assumptions will be optimistic.
One installer in the reviews specifically noted that their generation figures were deliberately conservative, and the customer confirmed actual output exceeded the estimate, which is the right approach. Ask any installer to show you the self-consumption ratio and export assumptions behind their savings figure, and cross-check those against your actual daily usage pattern and whether anyone is home during daylight hours.
What are the warning signs of a solar installer you shouldn't hire? expand_more
- –No structured handover of the monitoring app after installation, leaving you unable to track system performance or identify faults early.
- –Vague or uncommitted timelines at the quoting stage, with no clear schedule for installation once you sign.
- –Sales contact is responsive but the installation crew does not match that standard in knowledge or communication.
- –No clear answer on who handles post-installation warranty claims, particularly if the installer is acting as a reseller rather than the system designer.
- –Unwillingness to disclose site constraints upfront, such as roof warranty implications from mounting methods or shading issues that affect real-world output.
- –Difficult to reach after the job is done, with no evidence of remote monitoring or proactive follow-up if the system trips or underperforms.
What should you ask before hiring a solar installer? expand_more
- –Ask whether the installer holds a current Electrical Workers Registration Board (EWRB) licence and can supply their registration number for you to verify online.
- –Ask what self-consumption ratio and export buy-back rate underpin the savings estimate, and whether those figures are based on your actual usage data or a generic template.
- –Confirm whether app setup, monitoring walkthrough, and commissioning support are included in the quoted price or charged separately.
- –Ask specifically who handles warranty claims after installation, whether that is the installer directly or a third-party supplier, and what the response time commitment is.
- –Clarify the difference between the workmanship warranty the installer provides and the manufacturer warranties on panels, inverter, and battery, including what happens if the installer ceases trading.
- –Ask whether the mounting system used will void your roof warranty, as at least one reviewer specifically noted this as a point of differentiation between competing quotes.

Tengo Electrical
★ 5.0 17 reviews Top5 Score 1375★ 17Tengo Electrical gets electrical jobs finished on the day promised, with Brendan coordinating directly with other tradespeople where needed and keeping clients informed throughout. Pricing draws repeated specific mention as fair for the volume of work completed, and sites are left tidy enough that more than one client noted they barely knew he had been there.

Natural Technologies
★ 4.8 11 reviews Top5 Score 1305★ 9 4★ 2Natural Technologies installs solar panel arrays, battery systems, and off-grid setups, including technically demanding projects like century-old villas where modern infrastructure has to work within existing aesthetics. Dan takes time after commissioning to walk clients through how their system operates, including integration with third-party home automation platforms, so owners leave the handover with genuine working knowledge rather than a folder of manuals.
