The solar industry in New Zealand is still emerging, with many homeowners hesitant about the products and companies offering solar solutions. After re-entering the industry following a 30-year break, I noticed a significant gap in the quality of products and support provided. Choosing a reputable company and quality products is essential for a successful, long-term solar investment. Here are some tips to help you find a reliable solar company in New Zealand.
1. Check Reviews and References
Look for companies with solid reviews and references, particularly on platforms like Google. Be cautious, as some companies may have reviews for other services beyond solar installs. Don’t hesitate to ask for verbal references from past customers. A reputable company will readily provide a list of happy clients willing to vouch for them.
2. Teams vs. Subcontractors
Subcontracting is common in the solar industry, but it can sometimes disconnect you from the company you initially signed with. If a subcontractor will handle the installation, ask for specific referrals for the subcontractor. Companies with their own teams often have closer control over the quality of the job.
3. Product Reputation
Not all solar products are created equal, and due diligence is key. Research the brands and models quoted by the company. Australia is a great reference for evaluating brand reputation since they are about 10 years ahead of New Zealand in the solar market. Online forums and social media groups can reveal patterns in brand reliability and customer service.
4. New Zealand Warranties and Support
Make sure the product warranty is applicable in New Zealand, as some warranties may not cover the NZ market. This can leave homeowners vulnerable if issues arise. A quality brand should offer support independent of the installer, directing you to an authorised warranty installer if necessary.
5. Solar Education
Understanding solar basics will help you make an informed decision. A quality solar company should welcome questions and provide clear, honest answers. Beware of companies that seem overly sales-driven or pushy; a trustworthy company will prioritise your understanding and comfort.
6. Company and Customer Interactions
From site visits to communication, evaluate how the company interacts with you. Are they attentive, proactive, and thorough in explaining the process? Strong, customer-centric companies will prioritise your needs and offer ongoing support. Remember, your relationship with this company extends for the life of your solar system.
7. Insurance
Ask for proof of insurance, including public liability and workmanship coverage. If a subcontractor is involved, make sure they have appropriate insurance as well.
