Solaris New Hall: What It Means for Used Buses in Europe

Solaris expands production: the facts

On 23 June 2026, Solaris Bus & Coach inaugurated a new final assembly hall in Środa Wielkopolska, in the Greater Poland region, roughly 35 kilometres south-east of Poznań. This is not an incremental upgrade. According to Sustainable Bus, the new facility adds around 500 vehicles per year of production capacity.

Until now, final assembly of Solaris urban buses was concentrated exclusively at the Bolechowo plant north of Poznań, where the Polish manufacturer built its manufacturing core. Środa Wielkopolska already housed a steel frame welding facility dating back to 1998; that site now becomes part of a more complex production hub. With the new hall operational, final assembly runs in parallel across both locations.

Solaris has set an explicit target of 2,000 vehicles per year. In 2025 the company delivered 1,631 buses, of which 86% were classified as low- or zero-emission models. The additional 500-unit capacity from the new hall makes the 2,000-vehicle threshold technically achievable in the short term, once the site reaches full output.

The expansion does not stop there. Solaris has already acquired 47 hectares of land in the same area to build a second facility, dedicated to interurban buses, with operations scheduled to begin in 2029.

A shifting production profile: zero emission becomes the default

For anyone working in the used bus market, the most important detail is not the volume increase but the composition of the production mix. With 86% of 2025 deliveries classified as low- or zero-emission vehicles, Solaris is fundamentally reshaping the structure of its circulating European fleet.

In the first quarter of 2026, Solaris ranked second among the leading zero-emission bus suppliers in the European Union, again according to data reported by Sustainable Bus. The practical implication: the volume of conventional diesel or Euro 6 units being retired from fleets over the coming years will outpace what enters the market as new. The flow goes only one way.

For dealers and traders specialising in used buses, the logic is straightforward. Every new electric or hybrid bus delivered to a public or private operator generates, in the medium term, a disposal on the used market. The speed at which Solaris is pushing zero-emission vehicles into European fleets accelerates this replacement cycle, particularly in the urban and suburban segments.

The new capacity is also not uniformly distributed. The Środa Wielkopolska site focuses on urban buses. The future 2029 facility will target the interurban segment, where Solaris has already announced a new platform expected between late 2026 and early 2027. That product expansion will have distinct effects on the used market compared to the city bus segment, with different residual value dynamics and different geographic demand patterns.

Impact on used bus supply across Europe

Scaling up production of new buses is never neutral for the used market. More vehicles delivered today means more units entering the disposal cycle in five, seven, or ten years. But the effects are not only long-term; there are more immediate mechanisms worth watching.

First, operators renewing their fleets with new Solaris electric buses free up Euro 6 diesel units that flow directly into the secondary market. This process is already underway and will grow as deliveries increase. Central and Eastern European markets, Poland included, have historically been the primary destination for these second-life vehicles.

Second, Solaris's expansion into new markets, including North America where the company has already begun initial deliveries, redistributes demand for new vehicles geographically. This can ease competitive pressure in certain price brackets of the European used bus market, making specific categories more accessible for mid-sized operators.

Third, the creation of nearly 300 direct jobs at the Środa Wielkopolska site, plus several hundred indirect positions throughout the regional supply chain, strengthens Poland's manufacturing ecosystem in the bus sector. For dealers operating in Poland or sourcing from there, this consolidates the country's role as a reference point for vehicle maintenance, technical verification, and parts availability.

What changes for specialist dealers and traders

Anyone active in used bus trading across Europe should read this news with a forward-looking perspective. The trends emerging from Solaris's production expansion are not confined to a press release: they reshape expectations around supply, residual value, and the types of vehicles that will circulate on the secondary market over the next decade.

A few concrete considerations for those managing stock or working on sourcing.

Older Solaris models, particularly earlier generations of the Urbino in diesel and hybrid configurations, will exit operator fleets more quickly as public funding for green transition becomes available. The replacement cycle shortens. Those who anticipate these disposals gain a real positioning advantage.

The Solaris interurban segment is still relatively thin in the used market, but with the new platform launch expected by early 2027 and a dedicated factory to follow, this segment will also build critical mass in the secondary market. Dealers who develop expertise on these vehicles now are positioning themselves in a segment with growing demand but still limited supply.

The geographic concentration of Solaris production in Poland, and its continued growth, strengthens cross-border logistics for dealers moving vehicles from Eastern to Western Europe. Proximity to the production sites also simplifies access to technical documentation and the manufacturer's service network, a detail that matters more than it might seem in international used vehicle transactions.

Finally, the scale of the expansion, a second site of 47 hectares already planned, signals that Solaris is not optimising existing capacity. It is building a long-term manufacturing platform. For the used bus market, that translates into a reliable and structured supply flow for the next ten years at minimum.

Outlook: volume, quality, and timing

The European used bus market does not react to single events. It responds to structural trends that consolidate over time. The opening of Solaris's new hall in Środa Wielkopolska is one of those structural signals.

The trajectory is clear: Solaris is targeting 2,000 units per year, with a dominant share of zero-emission vehicles. Every unit delivered enters a lifecycle that, on average, eventually produces a disposal on the secondary market. With 2025 deliveries already at 1,631 units and additional capacity now live, the flow toward the used market will grow, in both volume and the technical quality of available vehicles.

For dealers, the question is not whether this supply will increase. It will. The question is when and in what form it reaches the market. Building the capability to capture it, through knowledge of Solaris models, familiarity with Polish technical documentation, and solid relationships with operators managing disposals, is work that starts now.
