Before you hire

Solar 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.

    Think Solar Christchurch (formerly Christchurch Solar)

    ★ 5.0 93 reviews +6 Top5 Score 167 +3
    5★ 92 4★ 1

    Christchurch Solar sends someone up onto the roof to physically assess the space before quoting, rather than relying on photos or guesswork. Post-installation follow-up comes from both the installer and the managing director, and the team responds to system faults the same morning they are reported.

    • ✓ Physical roof inspection at quote stage
    • ✓ Same-morning response to system faults

    Garden City Solar puts the same person on your roof as in your initial consultation, cutting out the middleman at every stage. After installation, they follow up proactively when rule changes or settings updates affect how your system runs.

    5★ 74

    Zero Electrical & Renewables walks clients through the design and build process from first visit to post-install follow-up, making the decision clear before any commitment is made. Their combined solar and electrical services mean the same team stays involved well after panels go on the roof.

    Reviews most often describe: Homeowners wanting a long-term solar relationship

    • ✓ Competitive quotes from multiple options
    • ✓ Consistent communication during install
    • ✓ Tidy worksite after completion

    Grenz Electrical

    ★ 5.0 63 reviews +3 Top5 Score 155 +2
    5★ 62 4★ 1

    ★ 4.9 28 reviews +1 Top5 Score 146 +4
    5★ 27 1★ 1

    CPS Solar designs systems sized specifically to each household rather than pushing a standard package, which reviewers say translates into production that meets or beats initial estimates. When a fault arose mid-holiday for the owners, Murray resolved the inverter issue daily from overseas rather than waiting until he was back.

    Reviews most often describe: Households wanting tailored solar systems and ongoing support

    • ✓ System output performs as quoted
    • ✓ Fault follow-up while owners were overseas
    • ✓ Grid export configured at commissioning

Before you hire a solar installer in Christchurch

Drawn from 176 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 up to 10kW can reach $18,000 to $20,000 depending on roof complexity, shading, and inverter brand. Adding battery storage typically pushes the total up by $8,000 to $15,000, and payback periods extend significantly as a result. No government rebate exists 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

Every 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 any installer's registration number through the public search tool 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 conduct and competency standards, and ask whether the installer holds SolarCert certification, a specialist credential that assesses solar PV knowledge above the basic electrician licence. Both credentials matter when it comes to grid connection approvals, because your local lines company will require the installation to meet specific technical standards. Christchurch reviewers noted cases where the person quoting was also the qualified electrician doing the install, which reduces the risk of work being handed off to less experienced contractors.

How accurate are the payback period and savings estimates I'm being given? expand_more

Payback periods of 8 to 12 years are realistic for a 5kW to 10kW system in New Zealand, but that range shifts significantly depending on how much of your generation you actually use yourself. Export buy-back rates from retailers sit around 8 to 17 cents per kWh, while you pay 28 to 35 cents to import, so self-consumption is where the real savings come from. Several Christchurch reviewers confirmed their systems performed as advertised, and one noted savings dropping a power bill from roughly $350 to a $2 credit, which reflects high daytime self-consumption rather than heavy exporting.

What are the warning signs of a solar installer you shouldn't hire? expand_more
  • –Missed appointments with no proactive follow-up, and promised quotes that never arrive, signal poor reliability before any contract is signed.
  • –A salesperson who visits but never physically inspects the roof or roof space is giving you a quote based on assumptions, not your actual site.
  • –Poor app setup at commissioning, where the system is left exporting power when the battery is barely charged, shows the installer is not completing the handover properly.
  • –No dedicated contact person post-install, making you chase the business when problems arise, is a red flag for long-term support.
  • –Vague or missing workmanship warranties at the time of quoting suggest the installer is not prepared to stand behind the quality of the job.
  • –Installers who subcontract the physical work to crews the salesperson has no involvement with often produce uneven quality between the sales experience and the actual installation.
What should you ask before hiring a solar installer? expand_more
  • –Ask for the installer's Electrical Workers Registration Board (EWRB) registration number and confirm it is current before signing anything.
  • –Ask whether they hold SolarCert certification and are members of the Sustainable Energy Association of New Zealand (SEANZ), both of which signal specialist solar competency beyond a general electrician licence.
  • –Ask what assumptions underpin the savings estimate, specifically what self-consumption rate and export buy-back rate they have used, and whether the estimate is based on your actual usage data.
  • –Ask whether app setup, monitoring walkthrough, and export settings configuration are included in the price, or whether you are expected to sort those yourself after install.
  • –Ask who your contact person is for warranty claims after installation, whether workmanship and component warranties are separate, and what the response time commitment is if something goes wrong.
  • –Ask whether the people quoting are the same people doing the physical install, or whether the work will be handed to a subcontracted crew.
