How to pick the right panel

Match the panel to your roof, not the other way round. Tight or shaded roof? Prioritise efficiency. Big clear roof? A great-value tier-1 panel goes further. Then weigh warranty (product + performance) and make sure the installer offers a solid workmanship warranty. Our choosing solar panels guide walks through it.

Frequently asked questions

Which brand of solar panels is best in NZ?+

There is no single best panel for everyone. The strongest options balance efficiency, warranty, local support and price. Tier-1 brands widely fitted in New Zealand — including LONGi, Trina, JinkoSolar, Canadian Solar and REC — all offer 25-year product warranties and proven reliability. The right one depends on your roof and budget.

What are the top solar panel brands used in NZ?+

Commonly installed tier-1 panel brands in New Zealand include LONGi, Trina Solar, JinkoSolar, Canadian Solar and REC. All are established global manufacturers with local warranty support. Compare them on efficiency, warranty and price rather than brand name alone.

Are more expensive solar panels worth it?+

Sometimes. Premium panels can offer higher efficiency (useful on small or shaded roofs) and slightly better long-term degradation, but a quality mid-tier panel from a tier-1 brand is excellent value for most homes. The installer and system design often matter more than paying up for the most premium panel.
