Solar panels in Auckland, at New Zealand's best price
With 2,060 hours of sunshine a year and some of the country's highest power bills, Auckland is one of the best places in New Zealand to put solar on your roof. We install right across the region, from Wellsford to Pukekohe.

A 6.6kW solar system in Auckland costs from $11,990 installed and generates roughly 8,900 kWh a year, saving a typical household around $1,900 annually. Most Auckland homes reach payback in five to seven years. Since May 2026 Vector's export limit has doubled to 10kW, so larger systems now make more financial sense than they did.
What size system does an Auckland home need?
Output below is calculated for Auckland's sunshine hours specifically. The same system in Invercargill produces meaningfully less, and in Nelson slightly more. These are the four sizes we install most often.

Indicative installed prices, GST included, for a standard single-storey Auckland roof. Output modelled on 2,060 annual sunshine hours. Savings depend on how much you use during the day, your retailer's buy-back rate and your plan. Your tailored quote confirms the real numbers before you commit to anything.
Why 5kW and 6.6kW became the standard sizes
There is a specifically New Zealand reason those two numbers appear everywhere. Until 2025, most lines companies including Vector applied a 5kW export limit to residential single-phase connections. A home with a 6.6kW or 8kW system had to throttle its inverter so it never pushed more than 5kW to the street, even on a brilliant January afternoon. Systems were sized around that ceiling.
That ceiling has lifted. From 11 May 2026 the default export limit across every New Zealand lines company rose to 10kW, and distributors now have to justify any lower limit on safety or reliability grounds. Lines companies can also offer dynamic limits that flex above or below 10kW depending on real-time network conditions.
The practical effect for Auckland homeowners is that an 8kW or 10kW system can now export at full output. If you are weighing up sizes, the old advice to stop at 6.6kW is out of date. It usually costs less per watt to go bigger at the outset than to add panels later, since a second install means new scaffolding, more labour and possibly a bigger inverter.
The standards your install must meet
- AS/NZS 4777.2:2020 for the inverter, with volt-var and volt-watt response modes enabled.
- AS/NZS 5033 for the installation and safety of the PV array itself.
- AS/NZS 5139 where a battery is included.
- Electricity (Safety) Regulations 2010 compliance, with all electrical work by an EWRB-registered electrician.
Systems with total inverter capacity under 10kW and single-phase inverters under 5kVA can generally use the simplified Part 1A connection process, which the distributor must process within 10 business days. We handle the Vector application as part of your install.
What's different about solar in Auckland
2,060 sunshine hours a year
Auckland gets more sun than Wellington, Christchurch or Dunedin. Combined with high power prices, that gives most Auckland homes a payback in the five to seven year range, at the faster end for New Zealand.
Vector's network and export approval
Every Auckland install needs a distributed generation connection application to Vector. Vector's own modelling has shown that accommodating unrestricted exports could require network investment of up to $4 billion, which is why limits exist at all. We lodge the application for you and design to the approved limit.
Coastal corrosion is real here
Large parts of Auckland sit within a coastal corrosion zone: the North Shore, the eastern bays, Waiheke, the west coast beaches. Salt air degrades unrated mounting hardware and frames fast. We quote coastal-rated racking and panels as standard where the address requires it, and it is one of the things cheaper quotes quietly leave out.
Varied roofs and terrain
Flat South Auckland sections, steep North Shore sites, older villas in the central suburbs with heritage constraints, and newer builds out west. Roof pitch, access and scaffolding differ enormously across the region, which is why an honest Auckland quote is address-specific rather than a flat rate.
Most residential solar installations in Auckland do not require building consent. Heritage overlays and some character areas are the exception, and we will tell you at quote stage if yours is affected.
The Auckland crew
Our installers are employed, not subcontracted, and they live in the region they work in. These are the people who will be on your roof.

A real job, real numbers
6.6kW system, Titirangi
A 1970s two-storey home on a west-facing slope with partial afternoon shading from native bush. We used a north-east split array across two roof planes and microinverters to stop the shaded panels dragging down the string.
