How to Choose the Right Solar Installer

Get Multiple Quotes

Try to get quotes from at least three or four solar installation companies to help you pick the best one for the job^[4]. This gives you a realistic sense of pricing, available products, and the level of service you can expect.

Check Customer Reviews

Get the full picture through customer reviews – the more the better^[4]. Google and Facebook reviews are usually more credible than handpicked testimonials on a company's website, though those hold some weight too. Word of mouth from friends, family, colleagues, and your local community can be invaluable^[4].

Verify Industry Credentials

Ask these important questions when evaluating installers^[4]:

• How long have they been operating in this industry?
• Can they supply a customer contact who will vouch for them?
• Are they a member of SEANZ (Sustainable Energy Association of New Zealand)?
• Do they belong to any other relevant industry organisations?
• Who'll be doing the installation and how many on-site installers will they supply?

SEANZ have a drop-down search bar on their professional directory page where you can read a detailed profile of any member company in your area and learn more about their track record and offerings^[4].

Research the Products They Use

Different installers work with different solar panel brands and inverter systems^[4]. Ask your quotes to specify the brands they're recommending and research these independently. A Google search of a specific brand and model will generate plenty of information to guide your decision. Since this system will change how you receive and process energy in your home, it's worth doing the research^[4].

Look for Longevity and Reputation

The solar power industry is relatively young in New Zealand. The length of time an installation company has been in the game is a good measure of who to hire^[4]. Providers with an excellent reputation and longevity should be on your shortlist. Companies that have survived and thrived for over a decade have proven their ability to deliver quality work and stand behind their installations.

What to Expect During Installation

Professional solar installation in New Zealand is straightforward when you work with experienced installers. Certified technicians understand the unique requirements for solar panels in New Zealand conditions, from coastal salt exposure to varying sun angles throughout the seasons^[2]. Most residential installations are completed within 1–3 days with minimal disruption to your daily routine^[2].

A quality installer will handle everything from initial consultation and site assessment through to installation and aftercare support. Many offer free quotes and consultations to help you understand your options before making any commitment.

Making Your Next Move

Switching to solar is one of the smartest investments you can make for your home and our planet. The key is choosing an installer with proven experience, solid credentials, and a genuine commitment to quality. Start by getting quotes from at least three reputable installers in your area, checking their reviews and SEANZ membership, and asking detailed questions about their experience and the products they use.

Whether you're in Auckland, Christchurch, Gisborne, or anywhere in between, there's a quality solar installer ready to help you reduce your power bills and embrace renewable energy. Take your time with the decision – it's an investment that'll pay dividends for decades to come.
