Now is a good time for photovoltaics and batteries
Make your own electricity for around €0.05/kWh
That cost stays fixed for the next 20 years. Your own solar plant can cover 20 to 80% of your consumption.
On average, the investment pays for itself in 4 to 6 years, because you produce most of your energy yourself and use batteries to cover short demand peaks (peak shaving).

Large battery storage for businesses
Three situations where battery storage pays off most:
1.
You run 24 hours a day and use a lot of power at night.
2.
Your reserved capacity is not enough at peak times.
3.
You need backup power instead of a diesel generator.
We handle indoor and outdoor installations, including fire safety.
We use LFP batteries rated for 6,000 to 8,000 full cycles, which means 16 to 22 years at one cycle a day. Warranty terms follow the manufacturer’s conditions.
Smart saving
Before drawing power from the grid, the system uses the energy stored in your batteries.
Peak shaving
Avoid paying for higher reserved capacity. Use batteries to cut peak demand and recharge them when the load is low.
Optimal trading
Take advantage of large price swings on the energy market. Our AI software trades on the SPOT market automatically, without affecting your operations.
Why work with us?
Turnkey solution
We do not bolt together a catalogue of parts. We design the system around your site, build it, commission it and walk you through it before handover.
Engineers, not sales scripts
The people who assess your site understand the technology. They design the system around it and stay reachable after handover.
Verified suppliers
We only install components we trust and have tested ourselves, from established manufacturers.
Reliable service
We respond fast, replace faulty parts like for like and work directly with the manufacturer’s support team.
Selected projects
National Forest Centre: Gabčíkovo
Backup power for a research station of the National Forest Centre. 125 kW of photovoltaics paired with 1,305 kWh of battery storage, sized so that a grid failure does not interrupt the measurements: the site switches over in under 10 milliseconds.
| System size: | 125 kW |
| Storage capacity: | 1,305 kWh |
Farm Žarnov
Battery storage added to a farm that was already generating its own electricity. 60 kW of photovoltaics with 120 kWh of storage took self-supply from 45% to 80%, so four fifths of the electricity the farm uses, it now makes itself.
| System size: | 60 kW |
| Storage capacity: | 120 kWh |
HOKOTEX
A photovoltaic system was installed in Rozvojova Street in Košice for a textile warehouse. The system uses 44 Canadian Solar CS7L panels with a power output of 600 W, 28 Jinko Solar 445N panels and a GoodWe ET hybrid inverter. The energy from the panels is stored by six Soluna batteries with a total capacity of 90 kWh, ensuring stable and reliable operation of the system, reducing electricity costs and supporting the energy independence of the warehouse.
| System size: | 38.9 kWp |
| Storage capacity: | 90 kWh |

ONSA Plus complex
Our campus is equipped with its own 28 kWp photovoltaic system installed on our building. This project demonstrates our commitment to sustainability and energy efficiency - we don't sell anything we don't use ourselves. Thanks to photovoltaics, we are able to cover approximately 38% of our total electricity consumption, reducing our energy costs and minimising our carbon footprint.
