The process
From first conversation to lifetime monitoring, you deal with one team that owns the entire outcome.
01
Consultation
We study your roof, your usage and your goals. No pressure, no scripts — a precise technical conversation about what's possible.
On-site survey · Shading analysis · Usage audit
02
Design
Our engineers model your system in 3D — panel layout, string design, storage sizing — optimised for yield and built around your architecture.
3D modelling · Yield simulation · Permit pack
03
Installation
An in-house crew, never subcontracted. Most residential systems are installed and weather-sealed in a single day, immaculately.
In-house crew · 1-day install · Full clean-up
04
Activation
We handle inspection, utility approval and grid connection. The moment you're commissioned, your meter starts spinning backwards.
Inspection · Grid approval · Commissioning
05
Monitoring
Your system goes live in the Solstice app. We watch every kilowatt, flag anomalies before you notice them, and service proactively.
Live app · Predictive alerts · 25-yr care

In their words
“It's the only home upgrade that's paid us back and kept paying. The design felt like architecture, not a utility install.”
