How much does a residential solar system cost in New Zealand? A quality residential system typically runs $15,000–$25,000 for straightforward grid-tied setups, while the premium integrated solar-plus-battery systems Luxco specialises in range from $30,000 to $80,000+, depending on system size, battery capacity and roof complexity. Every Luxco proposal is fixed-price and itemised.

What's the payback period? In the Auckland region, typically 7–12 years for a well-sized system — faster if you have high daytime usage, an EV, or a pool. Panels are warranted for 25 years, so the majority of the system's life is pure return.

Do batteries make sense in NZ? For most premium homes, yes. Batteries shift your free daytime energy into the expensive evening peak and provide automatic backup in outages. They're the difference between 40% and 90% self-sufficiency.

Can I go fully off-grid in rural Auckland or Northland? Yes. Luxco designs complete off-grid systems combining solar, battery storage and backup generation, sized to your property's real consumption. It's more achievable — and more affordable — than most people expect.

Will the panels suit an architectural home? That's our specialty. We design layouts to respect rooflines and sightlines, use all-black panels and concealed cabling, and coordinate with your architect and builder from the plans stage.

How long does installation take? Most residential installations are completed in 2–5 days on site, with grid connection paperwork handled entirely by us. New-build integrations are staged with your build programme.

Who handles the council and lines company paperwork? We do — including the Vector/Northpower application, inspection, and certification. You'll receive a full compliance pack (CoC, ESC, and PV commissioning records) on handover.
