Solar panels in Christchurch, at New Zealand's best price
Christchurch is flatter, sunnier and easier to work on than most New Zealand cities, which makes it one of the more straightforward places in the country to put solar on a roof. We install across the city, Selwyn and out to Banks Peninsula.

A 6.6kW solar system in Christchurch costs from $11,990 installed and generates roughly 8,600 kWh a year. Most Christchurch homes reach payback in six to eight years. Every installation needs a connection application to Orion, which we handle as part of the job.
What size system does a Christchurch home need?
Output below is calculated for Christchurch'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 Christchurch roof. Output modelled on 2,100 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 Orion 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 Christchurch 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 If you are weighing up sizes, the old advice to stop at 6.6kW is out of date.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 Orion application as part of your install.
Why solar works here
Genuinely good sun
Christchurch gets more sunshine hours than Wellington or Dunedin, and Canterbury's dry, settled weather patterns suit solar better than the region's reputation suggests.
Orion's network
Every Christchurch install needs a distributed generation application to Orion, which covers Christchurch, Selwyn and parts of Banks Peninsula and is owned by the Christchurch and Selwyn councils. We lodge it for you and design to the approved limit.
The rebuild advantage
A large share of Christchurch housing stock was built or substantially rebuilt after 2011. Newer roofs mean simple pitches, modern switchboards, sound structure and fewer surprises, which keeps install costs down.
Cold winters, high heating load
Canterbury households run heat pumps hard through frosty winters. That daytime heating load is exactly what solar offsets best, and it is why the case here is often stronger than the sunshine hours alone suggest.
Most residential solar installations in Christchurch 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 Christchurch 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.

6.6kW system, Halswell
A post-2011 rebuild on a flat Halswell section with a simple north-facing gable, a modern switchboard and no shading. A clean single-day install: fifteen panels across one roof plane, with the Orion application handled under the simplified process.
