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.

    Future Energy

    ★ 4.8 309 reviews +7 Top5 Score 179 +4
    5★ 288 4★ 7 3★ 3 1★ 11

    Future Energy coordinates solar, battery, and hot water heat pump installations as a single job, handling multiple components without requiring customers to manage separate trades. Installers have drawn praise from third-party electricians for clean, well-organised wiring work, which points to consistent standards on-site.

    Reviews most often describe: Full solar and battery system installs with support

    • ✓ Pre-installation site inspection included
    • ✓ System spec advice before purchase
    • ✓ Power bills tracked post-install

    Planet Electrical

    ★ 4.9 182 reviews +6 Top5 Score 166 +1
    5★ 174 4★ 7 1★ 1

    Hire them for a solar install that runs on schedule without scope creep or communication delays, since they document system details in advance and adjust quotes without friction. They teach customers how to use new systems after installation and turn up ahead of schedule, which suggests they pad timelines conservatively rather than running jobs tight.

    Reviews most often describe: Homeowners bundling solar with EV charging or heat pump work

    • ✓ Detailed pre-install system visuals and function explanations
    • ✓ Scope changes accommodated mid-quote without resistance
    • ✓ Installation completed within two days on larger systems

    Total Solar

    ★ 4.9 108 reviews +5 Top5 Score 163 +4
    5★ 105 1★ 3

    Hire them if you've received competing quotes and want straightforward advice without pressure to oversell your system. They respond quickly to enquiries, compare well on price across solar and complementary energy work, and resist upselling tactics that other installers use.

    Reviews most often describe: Homeowners comparing multiple solar quotes and wanting transparent pricing

    • ✓ Compares favourably on pricing against multiple competitors
    • ✓ Responds fast to initial enquiries and questions
    • ✓ Explains system monitoring apps during handover

    5★ 65 3★ 1

    Reviews mention heat pump and AC work, not solar installations. Without solar-specific feedback, it's not possible to assess this business for solar installer hiring decisions.

    GridFree

    ↑ 3
    ★ 4.7 71 reviews +5 Top5 Score 152 +8
    5★ 64 4★ 2 1★ 5

    GridFree excels at sizing systems correctly and explaining trade-offs like lithium versus alternatives without sales pressure, leaving customers confident in their choices. All kits arrive pre-assembled with manuals and tools, letting non-electricians install themselves, though one customer dispute over product claims and handling suggests claims should be verified before purchase.

    Reviews most often describe: Off-grid homeowners and lifestyle block installations

    • ✓ Complete kits with installation tools included
    • ✓ Talks through sizing and lithium cost-benefit upfront
    • ✓ Systems run unattended without constant battery monitoring

Before you hire a solar installer in South Auckland

Drawn from 164 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 up to 10kW can reach $18,000 to $20,000 depending on roof complexity, shading, and inverter brand. Adding battery storage adds $8,000 to $15,000 on top of that, and review evidence confirms batteries push payback periods well beyond ten years at current retail conditions. New Zealand has no government rebate scheme 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, look up the installer's registration number on ewrb.govt.nz, which is the publicly searchable EWRB register, because connecting a solar system to the grid is legally restricted to Registered Electricians. Beyond the basic licence, ask whether the installer holds SolarCert certification, which tests solar-specific knowledge beyond general electrical competency and is a practical way to assess specialist expertise. SEANZ membership is worth checking too, as it signals the company has agreed to industry conduct standards, though it is voluntary rather than a legal requirement. One installer in the reviews holds Master Electrician status, which gave a customer added confidence that the job would be done to a high standard first time.

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

Payback estimates in the eight to twelve year range are realistic for most New Zealand households, but the number shifts significantly based on how much solar power you actually use on-site rather than export. Export buy-back rates from retailers sit around 8 to 17 cents per kWh in 2025, while you pay 28 to 35 cents to import, so self-consumption is where the financial case is made. One reviewer quoted a six-year payback, and they noted they are low users, which suggests their system is well-matched to actual demand rather than built around optimistic export assumptions. Ask your installer to show the savings calculation split between self-consumed generation and exported generation, and check what export rate they have assumed.

What are the warning signs of a solar installer you shouldn't hire? expand_more
  • –A salesperson quotes a system without visiting the site in person, which means roof layout, shading, and switchboard compatibility have not been properly assessed.
  • –The deposit is taken and then communication drops off, with delays that were not disclosed upfront, a pattern that appeared in more than one review.
  • –Site constraints such as inverter sizing, backup capability, or the need for a wifi extender are only revealed after the deposit is paid, adding unexpected costs mid-project.
  • –Post-installation support is absent, leaving customers with no handover on how the system works or no one to call when performance falls short of what was promised.
  • –Billing disputes arise where charges do not match the work actually done, and the installer refuses to review or remeasure.
  • –Products sold are non-compliant with New Zealand electrical standards, which voids home insurance and exposes the owner to liability.
What should you ask before hiring a solar installer? expand_more
  • –Ask for their EWRB registration number and check it on ewrb.govt.nz before signing anything.
  • –Ask whether they hold SolarCert certification and are SEANZ members, as both signal solar-specific competency beyond a general electrician licence.
  • –Ask the installer to break down the savings estimate into self-consumed generation versus exported generation, and confirm what export rate they have assumed.
  • –Ask whether app setup, system walkthrough, and monitoring configuration are included in the price, since some customers received no handover at all.
  • –Ask who handles warranty claims after installation, whether that is the installer directly or a third-party contractor, and get the answer in writing.
  • –Confirm the workmanship warranty period separately from the panel and inverter manufacturer warranties, as these are different commitments with different timeframes.
