Before you hire a solar installer in Wellington
Drawn from 146 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. Larger systems with battery storage push costs to $20,000 or well beyond, as seen in reviews where one system with 18 panels and battery units cost over $40,000. Roof complexity, shading, inverter brand, and switchboard upgrades all affect the final price. There is no government subsidy 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
Before signing anything, search the installer's registration number on the EWRB register at ewrb.govt.nz to confirm they hold a current Registered Electrician licence, which is a legal requirement for connecting any solar system to the grid. SEANZ membership is a useful additional signal, as it requires members to meet competency and conduct standards, even though it is voluntary rather than a legal obligation. Ask the installer directly whether they hold SolarCert certification, which tests solar-specific knowledge beyond the basic electrician licence and reduces the risk of poor system design. Reviewers valued installers who visited the property in person, inspected the roof and roof space, and tailored the system design rather than applying a generic estimate.
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 is 8 to 12 years, and adding battery storage often pushes that to 15 years or more because battery costs are still high relative to current savings. The key variable is self-consumption: importing power costs around 28 to 35 cents per kWh, but most retailers only pay 8 to 17 cents per kWh for power you export, so households that are home during the day and shift appliance use to peak generation hours will see the best returns. Ask any installer to show you the self-consumption ratio assumed in their estimate and to confirm what export rate they have used, since an overly optimistic export rate will inflate the projected savings significantly.
What are the warning signs of a solar installer you shouldn't hire? expand_more
- –A salesperson who impresses but the installation crew does not match that standard, leaving you chasing updates mid-job.
- –No app setup, system walkthrough, or handover at completion, leaving you unable to monitor your own generation.
- –Failure to respond to post-installation questions, with one reviewer waiting over seven weeks for a reply on a critical grid-outback question after paying more than $40,000.
- –Vague or shifting timelines, with one install stretching to nearly a month due to a design issue that should have been caught before work started.
- –Careless handling of your property during installation, including damage to garage contents that went unacknowledged.
- –No clear process for ongoing support, warranty claims, or remote monitoring after the job is complete.
What should you ask before hiring a solar installer? expand_more
- –Ask whether they hold current EWRB registration and SolarCert certification, and verify the EWRB number yourself at ewrb.govt.nz before signing.
- –Ask what self-consumption ratio and export buy-back rate they have used in the savings estimate, and whether they have based the design on your actual power bills rather than a generic household profile.
- –Ask whether the quote includes app setup, a system walkthrough, and connection of monitoring so you can track performance from day one.
- –Ask who handles warranty claims after installation, whether that is the installer directly or a third-party supplier, and what the response time commitment is.
- –Ask separately about the workmanship warranty and the component warranties on panels, inverter, and battery, as these are different documents with different terms.
- –Ask whether they will handle all paperwork required by your lines company for grid connection, and confirm the timeline for that approval before you commit to an installation date.
