New businesses: 50% off your first 6 monthsSunshine Solar has been installing solar in Canterbury since 2004, making them one of the longest-running local specialists in the region. They're a SEANZ-accredited member with a long local install history, a solid choice if you want an established, proven local operator.
CPS Solar has 14 years' experience and a genuine track record on larger jobs, including commercial installs at Arvida Parkland retirement village and Move Logistics in Rolleston. They also design solar and EV charger installs as an integrated package, useful if you're planning both.
Lightforce Solar is New Zealand's largest solar installer by volume, and unlike many national names they run their Christchurch installs with an in-house local team and warehouse based in Hornby South rather than subcontracting the work out.
Garden City Solar is run personally by Zac, a qualified electrician and solar inspector, who handles each job from first enquiry through to commissioning. Reviewers consistently mention his direct involvement and tidy finish, a good fit if you want to deal with the same person throughout.
Zero Renewables operates alongside sister company Zero Electrical as part of the wider Zero Group, giving them Master Electrician-certified electrical backing alongside their SEANZ-accredited solar work. They cover Canterbury and the West Coast from their Halswell base.

Not all solar quotes are equal. Check whether the installer is a SEANZ-accredited member, since this means they work to an industry code of conduct, and confirm which panel and inverter brands they use, as this affects both performance and long-term warranty support.
Electricians carrying out grid-tied (mains parallel) solar work need an Endorsed Mains Parallel Generation Systems registration from the Electrical Workers Registration Board, with the requirement phasing in for licence renewals from September 2026, so it's worth asking whether your installer holds this. Also ask how they handle the retailer paperwork and network connection, since a good installer manages this for you rather than leaving it to you to sort out.
Cost depends on system size, panel and inverter brand, and roof complexity, so get at least two or three itemised quotes to compare like for like. Ask what's included, panels, inverter, mounting, wiring, the retailer paperwork and network connection, since a low headline price can exclude some of this.
As of October 2025, most residential rooftop solar installations under 40 square metres per roof no longer need building consent, which covers typical residential systems. Confirm with your installer or council if your project is larger or more complex.
Any electricity your system generates beyond what your home uses is exported to the grid, and your retailer pays you a buy-back rate for it. From July 2026, major retailers must offer time-of-use pricing and pay rebates for electricity exported at peak times, so it's worth comparing retailer export rates alongside installer quotes.
Yes. Christchurch receives over 2,000 sunshine hours a year, among the higher totals for a New Zealand city, which makes rooftop solar a genuinely viable option for most well-oriented roofs in the area.
Not necessarily straight away. A battery lets you store and use more of the power your panels generate rather than exporting it, but it adds meaningfully to the upfront cost. Many Christchurch homeowners install solar first and add a battery later once they know their usage pattern.
