Harvest
An organic photovoltaic cell draws energy from ambient light. Workshop lighting is enough: full sunlight is not required.
Building the infrastructure of tomorrow
More people. More services. Fewer resources.
As the world grows and infrastructure expands, organizations face a common challenge: delivering more value, greater resilience and better services while consuming fewer resources. SunyGreen develops the autonomous technologies that make this transition possible.

A world under pressure
Infrastructure is expanding. Resources are not.
A global contradiction is emerging. Around the world, infrastructure is becoming more connected, more complex and more essential. Yet the resources required to power, maintain and sustain these systems remain limited. The challenge is no longer growth alone. It is sustainable growth.
More infrastructure
It is expanding across every sector, at a pace that is not slowing.
More connectivity
It now reaches every environment, including the least accessible.
Finite resources
Energy, materials and maintenance cannot simply be scaled up.
Growing expectations
Safety, performance and sustainability are now expected together.
Why it matters
When systems fail, the impact is not technical. It is human.
Infrastructure exists to serve people. Requesting assistance, accessing a service, triggering an alert: every interaction matters, and each one relies on infrastructure that has to respond.
Safety
Raising the alert at the moment it actually changes something.
Accessibility
A simple gesture, within reach, in any environment.
Reliability
A system that answers without depending on a battery or a cable.
Continuity
A service that is not interrupted for maintenance.
The shift
A new model is emerging
Less dependency, more resilience. Infrastructure should not require continuous intervention to remain operational.
Less maintenanceMore reliability
Less wasteMore sustainability
Less complexityMore simplicity
Less dependencyMore autonomy
Our response
Four steps, no battery
SunyGreen receives no energy from outside. It harvests what is already present in its environment, stores it, and communicates only when it matters.
Store
An ultra-low-power management circuit smooths the supply and builds a reserve that covers the hours without light.
Transmit
BLE Coded PHY carries the message beyond 800 metres, through concrete, for a minimal energy cost.
Act
The alert reaches the person concerned. No cabling, no dedicated gateway, no intervention.
Impact
What energy autonomy changes
Environmental
Less waste, lower resource use, a reduced footprint: every device deployed means disposable batteries avoided for life.
Economic
Less maintenance, greater uptime, faster deployment: total cost of ownership falls and efficiency rises.
Strategic
Safer interactions and improved continuity of service, carried by an IoT value chain designed and validated in Europe.
Applications
One platform. Multiple environments.
One technology answers wherever energy, cabling or range stand in the way. The project focuses first on three priority sectors; the others will follow.
The range and autonomy figures shown are project targets, currently being validated in real-world conditions at the pilot customer site.
Comparison
Why SunyGreen is different
