North Star

Your roof is
a server.

North Star runs real compute on the solar you already have — answering and proving over your data, which stays in your own hands. A roof stops being just an energy asset and becomes an infrastructure asset. Improving what your panels collect is the bonus.

Turn your solar into servers
Pick a roof. See the compute it supports — the scarce, high-value resource — plus the live service it runs over data that stays in its owners’ hands. Both from the energy your panels already waste and from a dedicated build.
Normally: a data-center rack, a grid contract, and a monthly cloud bill. Validiti: your existing panels. A roof stops being an energy asset and becomes an infrastructure asset.

Solar is the server

The node runs the same substrate as the live demos here — answer and prove over whole archives in milliseconds, while the data stays in its owner’s hands — on the power a panel already makes. No grid contract, no cloud bill.

Fueled by what you waste

Every array throws energy away — the clipped midday peak, the curtailed surplus when the battery’s full. North Star is a flexible load that eats exactly that. The side benefit: your array collects more.

Scale to thousands

Roofs dwarf data-center demand and follow the sun, not the grid. Put a node on schools, churches, and rooftops — a decentralized fabric that reaches where the central model can’t.

North Star is how the fabric gets built — roof by roof.

Run a node for your own data, or deploy it at scale with us and put your roofs to work. We build the fabric together — and grow it market by market.
