Trust your cafe solar energy
Siriteja solar systems help save money, protect equipment and prevent businesses from stopping.

The restaurant business does not tolerate unpredictability
Power outages
When electricity goes out, cash registers and refrigerators stop, the restaurant falls out of work.
Power surges and equipment breakdowns
Coffee machines, air conditioners and refrigerators are the first to suffer from an unstable network.
High accounts and seasonal fluctuations
During low season, even when the flow of guests decreases, equipment continues to operate and electricity costs do not fall.

The sun's energy works for you without interruption
The system controls energy automatically. This does not require your intervention.
The sun feeds the panels
During the day, energy is supplied directly to the café.
The battery accumulates excess
The reserve is used in the evening and during shutdowns.
Intelligent management
The system automatically balances the load, includes a reserve and notifies via the app.
The reserve is activated instantly
The equipment is protected from power surges and continues to operate.

- Works seamlessly even when the network is down
- Predictable bills during high season and lower costs during low season
- Eco-image and guest trust
