Photovoltaics
Rooftop, farm building or solar carport: your surplus is bought back at a low price, or not at all. A miner consumes it on site, during production hours.

Your unused electricity becomes income
Solar surplus, small hydro, wind, biogas or under-used contracted power: mining turns every wasted kWh into bitcoin. We size it, install it and monitor it.

Who is it for?
You produce more than you consume
Selling your surplus earns little, and storing it is expensive. A miner consumes your production on site, when it is available, and stops when you need it.
Small hydro
Mill, micro hydro plant, canal turbine: steady generation, day and night, ideal for miners running around the clock.
10 kW à 1 MWWind, biogas, cogeneration
Variable generation or an engine that has to keep running: mining absorbs the energy when nobody is asking for it.
20 kW to several MWUnder-used contracted power
Paying for contracted power you don’t use at night or at weekends? Make it pay with a controllable load.
36 kVA and aboveHeat demand
Greenhouse, swimming pool, drying, workshop heating: a hydro miner gives back the energy it consumes as hot water at 50-60 °C.
3 to 6 kW recovered per machineHouseholds with surplus
A few kW of surplus solar? A quiet home miner converts it into satoshis without touching your installation.
0,3 à 3 kWWhy mining?
The ideal flexible load for variable generation
A Bitcoin miner is an electrical load that starts and stops within seconds, without wear, and earns down to the second. Perfect for absorbing generation that varies with the sun, water or wind.
+33 6 32 49 26 41-
Starts and stops in seconds
The miner follows your generation: full power when there is sun or water, stopped when you need the electricity.
-
Paid by the second, in bitcoin
No buy-back contract, no customer to find: the pool pays you your share every day, wherever you are.
-
Heat as a bonus
With a hydro miner, the electricity consumed comes out as hot water: heat a building, a greenhouse or a pool.
-
Remotely controlled
Monitor production, hashrate and temperature from your phone; we can also supervise it for you.
What your kWh is worth
Your kWh is worth more mined than sold back
In France, the feed-in tariff for surplus solar power has fallen to around 4 to 5 cents per kWh. Used on site by a recent Bitcoin miner, the same kWh earns much more: here is today’s value, calculated with our network data updated every hour.

The middle ground
Between the home miner and the data centre: the Antrack
Too much generation for a home miner, not enough for a container? The Antrack is a ready-to-use hydro cabinet for 4 miners, up to 24 kW: it fits in a garage or a barn, consumes your electricity on site and, with the AR22, turns the miners’ heat into hot water.
- Home miner0,3 à 3 kW
- Antrackup to 24 kW
- Data centre100 kW and above
- No building or civil works required
- Liquid cooling, quiet by miner standards
- Recoverable heat as hot water (AR22)

The machines
Which miner for your available power?
Quiet and compact, they plug into a standard socket: the right choice for a household solar surplus.
Air-cooled Bitcoin miners: the best power-to-price ratio for a garage, a barn or a ventilated plant room.
Water-cooled: almost silent, more efficient, and the heat can be recovered. With the Antrack or a water-cooling kit, the installation is ready to use.
Between 5 and 24 kW, the Antrack houses 4 hydro miners in a ready-to-use cabinet; beyond that, we host your machines or deliver several cabinets.

How it works
From your meter to your first satoshis
- 01
A call, an assessment
You describe your generation (power, hourly profile, seasonality) and your consumption. We estimate what one or more miners can get out of it.
Free, no obligation - 02
Sizing
Choice of machines (air or hydro) and how many, control based on generation, cooling and heat recovery.
Detailed quote - 03
Installation & commissioning
Delivery, electrical connection with your electrician, network and pool configuration, load tests. You see your first satoshis the same day.
Anywhere in France - 04
Monitoring & maintenance
Remote supervision, alerts, preventive maintenance and after-sales support with parts in stock: your machines keep running, you collect the income.
After-sales support in France
Every installation is different: let’s talk about yours.
A 15-minute call is enough to scope your project: available power, generation profile, premises, cooling, noise. You come away with an initial estimate and the next steps.

Frequently asked questions
Before connecting a miner to your generation
How much can it earn?
It depends on your available power, the number of hours it is really available and the bitcoin price. With electricity you already produce, the kWh costs you nothing: in October 2026, a kWh used by a recent ASIC earns more than twice its sale price at the French surplus feed-in tariff. The “What your kWh is worth” simulator above gives today’s value; call us for an estimate based on your figures.
My generation varies: can the miner handle being stopped?
Yes. An ASIC is designed to start and stop without any particular wear. We set up a control system (relay, contactor, energy management box) that starts the machines when there is surplus and switches them off when you need the power.
What is the minimum power required?
A home miner starts at 300 W and plugs into a standard socket. A Bitcoin ASIC draws 3 to 6 kW and needs a dedicated circuit (often three-phase for more than two machines). From a few tens of kW upwards, we are talking about a rack or a container.
Is it noisy? And what about the heat?
An air-cooled ASIC makes as much noise as a vacuum cleaner: it needs a plant room or a barn. A hydro model is almost silent and its heat comes out as hot water (50-60 °C), which can be used to heat a building, a greenhouse or a swimming pool.
Can you install the machines at my site?
Yes, anywhere in France. We deliver, connect with your electrician, configure and test. We can also host your machines on our premises if your site is not suitable.
