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.

Before you hire a solar installer in Wellington
Drawn from 191 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 higher, with batteries alone often adding $8,000 to $15,000 to the total.
Roof complexity, shading, and inverter brand all affect the final price, and one Wellington reviewer noted paying well over $40,000 for an 18-panel, 6-battery system. There is no government subsidy for residential solar in New Zealand as of 2025, so get at least three quotes and confirm each one reflects your actual roof layout and power usage.
How do I check if a solar installer is properly accredited? expand_more
Every installer who connects 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 any installer's licence number through the public register at ewrb.govt.nz before signing 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 specific to the solar industry.
Asking whether the installer holds SolarCert certification is a practical way to gauge specialist solar knowledge above the basic electrician licence. Installers who came out to physically assess the property before quoting, as noted in several Wellington reviews, are a good sign that the team has the site-specific expertise to back up their credentials.
How accurate are the payback period and savings estimates I'm being given? expand_more
Payback estimates of 8 to 12 years are realistic for a 5kW to 10kW system in New Zealand, but the number is highly sensitive to how much of the solar generation you actually use in your home. Export buy-back rates from retailers currently sit around 8 to 17 cents per kWh, while you pay 28 to 35 cents to import power, so self-consumption is where the real savings come from.
Adding battery storage often pushes the payback period beyond 15 years at current battery prices, which is worth confirming before committing to the expense. Ask any installer to show you the self-consumption ratio they have assumed in their model, and check whether it matches your household's daytime usage patterns.
What are the warning signs of a solar installer you shouldn't hire? expand_more
- –A salesperson who uses artificial urgency or claims prices are about to rise is a red flag, as several Wellington reviewers specifically called this out as a reason they rejected certain providers.
- –No response to post-installation support questions is a serious concern; one reviewer waited over seven weeks for a reply on a fundamental system question after paying more than $40,000.
- –Installation taking far longer than quoted, with the customer having to chase for updates, suggests the company is overcommitted and understaffing individual jobs.
- –Damage to property during installation, such as collapsed shelving in a garage, points to a crew that is not taking basic care on site.
- –Vague or absent handover on how to use the monitoring app indicates the installer is not following through on the full scope of the job.
- –A one-size-fits-all quote produced without a physical site visit suggests the system design may not account for your actual roof orientation, shading, or usage.
What should you ask before hiring a solar installer? expand_more
- –Ask whether the installer holds a current Registered Electrician licence with the Electrical Workers Registration Board (EWRB) and whether they are a member of the Sustainable Energy Association of New Zealand (SEANZ), then verify both independently.
- –Ask what self-consumption ratio the savings estimate assumes, and confirm whether that reflects your actual household usage pattern during daylight hours.
- –Ask who handles warranty claims after installation: whether it is the installer directly or a third party, and what the workmanship warranty covers separately from the manufacturer's component warranty.
- –Ask whether the price includes app setup, a full system walkthrough, and all paperwork required for grid connection and compliance certification with your lines company.
- –Ask how the installer manages scheduling: whether your job will have a dedicated crew or be fitted around multiple simultaneous installs, as delayed completions were a recurring frustration in Wellington reviews.

How are the top solar installers in Wellington chosen? expand_more
We build this page from Google Maps results for solar installers in Wellington. 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.
