We handle the complexity. You keep the outcome.
Energy is changing. Homes can now generate power — but most of it is still poorly used or wasted. 1Sun connects solar, storage, homes and the grid into one coordinated system, so energy flows where it creates the most value.
Four steps from roof to earnings.
The same clear path whether you're installing from scratch or connecting a system you already own.
Assess your home
Enter your postcode and a few details about your roof, usage and any existing kit. We model your home's energy profile and recommend the service that fits — buy, subscribe, or boost.
Install & connect
Accredited installers fit solar and battery hardware, or we securely connect the system you already have. Everything is commissioned, tested and linked to the 1Sun monitoring app.
Optimise continuously
Our platform decides — minute by minute — when to store, use or export energy. It charges when power is cheap and releases it when demand and prices peak, without you lifting a finger.
Earn from your energy
What used to sit unused becomes measurable income. You see every kilowatt-hour, every export and every payment in the app, and your system gets smarter as the network grows.
How coordination becomes income.
On its own, a home exports surplus power whenever the sun happens to shine — often when everyone else is exporting too, and prices are low. Coordinated across thousands of homes, that same energy can be timed to the moments the grid needs it most.
1Sun aggregates flexibility from every connected home and offers it to grid and market programmes. The value that creates flows back to you as earnings — the part of your system that was invisible before.
Small, constant decisions compound.
We don't just connect systems. We handle the complexity.
We guide the process. We coordinate the transition. You stay focused on the outcome. Where relevant, 1Sun supports access to suitable energy suppliers through comparison and switching journeys — helping you understand when a change can improve your energy profile and earnings.
