This solution is perfect for small households with 1-2 occupants, such as those who have recently moved into a new home or are enjoying retirement. It offers an efficient, cost-effective energy option. For instance, in Auckland, the system can generate around 429 kWh per month in winter and up to 798 kWh in summer.

With a smart control system or appliance scheduling, you can maximize solar energy use during the day to power devices like microwaves, heat pump water heaters, dishwashers, washing machines, and dryers. This significantly reduces nighttime electricity consumption, lowering energy bills while providing a sustainable and economical power experience.

The system also includes a Hybrid Inverter with a pre-configured battery interface, allowing for easy future battery upgrades without replacing major components—offering both low initial costs and long-term flexibility.

Explanation: The price includes GST but excludes shipping. Shipping will be calculated at checkout based on your delivery address.

You can use your own installation company — we’ll still provide technical support and after-sales service. Or choose from our recommended installation companies. 👉 How TEG ensures long-term benefits?

Use the Solar Savings Calculator below to estimate your installation cost based on system size and roof conditions. The estimate is usually accurate but excludes Special Cases like scaffolding or wall penetrations. Final price will be confirmed after onsite assessment.
