Solar panels in Tauranga, in one of New Zealand's sunniest regions
The Bay of Plenty gets more sun than almost anywhere else in the country, which makes Tauranga one of the best places in New Zealand to own solar. We install from Ōmokoroa through to Pāpāmoa and out to Te Puke.

A 6.6kW solar system in Tauranga costs from $11,990 installed and generates roughly 9,300 kWh a year, more than the same system in Auckland or Christchurch. Most Tauranga homes reach payback in five to seven years. Installations connect through Powerco, and we manage the application.
What size system does a Tauranga home need?
Output below is calculated for Tauranga'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 Tauranga roof. Output modelled on 2,260 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 Powerco 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 Tauranga 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 If you are weighing up sizes, the old advice to stop at 6.6kW is out of date.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 Powerco application as part of your install.
Why solar works here
Best sunshine hours in the North Island
The Bay of Plenty consistently ranks among New Zealand's sunniest regions. The same system generates meaningfully more here than in Auckland, Hamilton or Wellington, and payback is correspondingly shorter.
Coastal, almost everywhere
Mount Maunganui, Pāpāmoa, Ōmokoroa and Matua all sit in a salt-air corrosion zone. Coastal-rated mounting hardware is not an upgrade here, it is a requirement, and it is the single most common omission in cheap Tauranga quotes.
Powerco's network
Tauranga and the western Bay of Plenty connect through Powerco, the country's second-largest electricity network. We lodge the application and design to the approved export limit.
Growth corridors
Pāpāmoa East, Ōmokoroa and Te Puna have grown fast, and new builds are the cheapest, fastest installs we do: clean pitch, no shading, modern switchboard.
Most residential solar installations in Tauranga 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 Tauranga 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.

What a Tauranga install looks like
6.6kW system, Pāpāmoa
A single-storey home a few streets back from Pāpāmoa Beach, well inside the salt-air corrosion zone. Fifteen panels on corrosion-rated racking across a simple north-facing pitch, with the Powerco application lodged as part of the job.
