Choosing a high-quality 6.6kW solar system is about the total value delivered over the system's 25-year life — more energy, less maintenance, better warranty protection, and greater peace of mind.
Defining Quality in a Solar System

- Inverter with 97.5%+ European Efficiency and local New Zealand technical support
- CEC-accredited installer with NETCC Approved Seller status
Quality Pays for Itself
A high-quality system that performs 10% better and lasts 5 years longer than a budget alternative delivers tens of thousands of additional dollars in savings over its lifetime. Quality is the smart financial choice.
