Astech already works across Waiheke Island, so we understand the logistics, remote locations and off-grid realities that many mainland-only solar installers don't.
We design and install solar, battery and EV charging systems for Waiheke homes that need genuinely reliable, well-planned power.





If you're building or renovating on the island, bringing us in early means solar, battery placement and switchboard capacity can be planned into the design from the start.
This avoids the compromises, and the extra site visits, that come with adding solar to a finished Waiheke home later.



Some do, but logistics can be a genuine challenge for installers who don't visit regularly. Astech already has an established presence on Waiheke, so access and scheduling are built into how we work, not an added complication.
Some properties on the island are off-grid or have limited grid connections, though most are still connected to the mains. We assess your specific property's connection before recommending a system, rather than assuming one setup fits all.
Not always, but properties further from the main grid often benefit more from battery backup than typical mainland homes. We'll talk through this honestly based on your property's actual connection and location.
Yes. We work directly with Waiheke builders and architects to plan solar, battery and electrical systems into new builds and renovations from the early design stages.
