Twenty years of solar energy. And we’re just getting started.
In 2004, we installed our first panels on a roof in Neuchâtel to offset the electricity used by our servers. Today, our plants produce more than a hundred times as much — far more than our infrastructure consumes. That is why Horus Networks became Horus Energy SA in 2025.

How it works
The power grid, our battery.
By day
The sun is shining: our panels produce electricity. Our servers use a small part of it; the rest — by far the largest share — is fed into the grid and powers our neighbours directly.
At night
The sun has set: our servers draw from the grid the energy we fed into it during the day. The grid acts as a huge battery — with no chemical batteries to manufacture or recycle.
The balance
Over a year, our plants produce far more electricity than our servers consume. Every kWh used by your website, your e-mails or your text messages is therefore offset — and largely exceeded — by our own solar production, since 2004.
