Flexible – Consistent – Tauro

3/13/2024 / Swidno, Poland
Consistently sustainable, consistently economical: Poland's market leader in the wood industry is focusing on renewable energies. Tartak Olczyk operates its production and storage facilities as much as possible with self-produced green electricity made from biomass and solar energy. With an efficient combination of eleven Fronius Tauro inverters and four Fronius Symo inverters, the company benefits from 100% self-consumption.

 

 

Customized energy solution:
PV system and biomass power plant

From sawn lumber, wood pellets and turned fencing palisades to roof trusses – Poland's most successful wood manufacturer Tartak Olczyk offers a wide range of products made from pine. The demand for natural products is high and the energy required in production is growing along with it – especially in summer. To better fulfill the steadily growing energy demand for sawmill machinery and other equipment, the environmentally conscious company decided to expand its energy supply made with biomass from production waste to include another sustainable source of electricity: solar power.

The new large-scale commercial PV system, in combination with the biomass power plant, now generates enough green electricity to supply much of the energy required by the production halls and all warehouses. To implement this customized energy solution, Tartak Olczyk relied on Fronius and our robust Fronius Tauro and Fronius Symo inverters.

 

 

Maximum design flexibility, maximum performance

“The project required us to install a high-performance PV system with a feed-in on three different roofs, each 150 meters long, which would be added to the existing biomass power plant and thus give the company greater autonomy from the public power grid. It was a giant task. Together with Fronius, we were able to find a customized and durable solution that is tailored exactly to our needs.”, reports Seweryn Grabiec from installation company Soleko Polska.

The most notable challenge in the system design was the connection to the AC grid, which is located at the very end of one of the buildings. The solution: AC daisy chaining. With this function, several of our Fronius Tauro project inverters, with a total output of up to 200 kW, can be linked in a series in a way that’s not only practical but above all cost-efficient. This eliminates the need for additional components as well as cabling. The installed eleven Fronius Tauro and four Fronius Symo inverters reliably deliver the maximum yield of sustainable solar power, 100% of which is used for self-consumption.

 

 

» Essential components such as AC/DC surge protection are already integrated in the Fronius Tauro ex works, so we didn't have to worry about reliable protection – nor did we have to factor in any additional components or installations for it. What's more, Fronius Tauro doesn’t require any overhead protection at all, even outdoors. That's what sold us on it. «

- explains Seweryn Grabiec from Soleko

 

 

Extremely economical

Because the project inverters are located close to the southeast- and southwest-facing PV modules, transmission losses are reduced. At the same time, the system’s multi-sided orientations continuously produce large amounts of solar power from morning to evening. This cuts the overall cost of operating the large-scale PV system in `Swidno, Poland, to a minimum.

Additional arguments in favor of the Fronius Tauro include the fast handling of service cases and the targeted online support provided by the digital tools from Fronius such as Fronius Solar.SOS. Instead of having to replace the entire inverter, only the affected power stage set needs to be replaced when necessary – and this can be done directly at the site and by just one person. This effectively saves companies time and money.

 

 

High yields in harmony with nature

We are proud that the Tartak Olczyk wood manufacturer placed its trust in us to implement its customized energy solution and is now benefitting from 100% self-consumption and the greatest possible energy autonomy. This means the project goal has been fully achieved.
