The next step is coordination.
Energy is changing. Homes can now generate their own power — but most of it is still poorly used or wasted. We started 1Sun to fix that: to connect solar, storage, homes and the grid into one coordinated system, so energy flows where it creates the most value.
What is usually unused becomes measurable earnings.
1Sun connects solar, storage, homes and grid interaction into one coordinated system, helping energy flow where it creates the most value. What is now only individual becomes part of a larger network.
We believe the home is the most important unit of the future energy system — and that when millions of them work together, clean energy stops being a cost to manage and starts being infrastructure that pays.
The next chapter of Tomatopia.
1Sun grew out of a simple frustration: households were installing solar and batteries, doing the right thing, and still leaving most of the value on the table. Energy was being generated locally but coordinated nowhere.
So we built the layer that was missing — a platform that installs, connects and optimises home energy systems, then coordinates them at scale. We don't just connect systems. We handle the complexity, guide the process and coordinate the transition, so people can stay focused on the outcome: a cleaner grid and a system that earns.
Principles behind every install.
Make energy count
Every kilowatt-hour a home generates should do useful work or earn its keep. Waste is a design problem, and we design it out.
Keep it honest
Clear quotes, clear plans and clear numbers in the app. We're a technology company, not an energy supplier, and we say exactly what we do.
Stronger together
One home is a start. A coordinated network is infrastructure. The more homes join, the more value there is for everyone on it.
Behind every home, a bigger system is forming.
This is how distributed energy becomes infrastructure — and homes become part of the grid. We're building 1Sun for the moment when coordinated home energy isn't the exception, but the way the system works.
