In the evolving landscape of renewable energy, the integration of solar photovoltaic (PV) modules into infrastructure is gaining momentum. A prime example of this innovation is the use of PV modules as noise barriers. This ingenious solution addresses two critical urban issues: noise pollution and the need for sustainable energy. SoliTek and Stalcorp have pioneered this approach, proposing the use of solar PV modules as noise barriers to mitigate highway noise, a prevalent pollutant in urban environments.
PVNB: The Concept
Noise pollution, especially from highways, is a significant concern in densely populated areas. Traditional noise barriers help reduce noise levels but do not contribute to energy production. By integrating PV modules into these barriers, it is possible to not only reduce noise but also generate renewable energy, making efficient use of urban space. This example of dual-functionality is know as a photovoltaic noise barrier (PVNB).
SoliTek and Stalcorp’s Projects
SoliTek, in collaboration with Stalcorp, has launched innovative photovoltaic noise barrier projects in Lithuania. These projects are among the first in the Baltic states to merge solar energy production with noise reduction.
Highway Project on E85
Location: Along the E85 European motorway connecting Kaunas and Vilnius.
Specifications: Utilizes 56 bifacial solar modules.
Output: Aims to produce 15 MWh of electricity per year.
Railway Project near Vilnius
Location: Alongside a railway near Vilnius.
Specifications: A 70-meter long, 4.5-meter high wall equipped with 60 frameless, dual-glass transparent SoliTek Solid Bifacial 370W modules.
Output: Expected to generate 13.2 MWh of electricity annually.
These projects are designed to maximize solar efficiency while significantly reducing noise pollution. The bifacial modules used are resilient to extreme weather conditions, ensuring durability and consistent energy production.

Global Impact
PVNBs are gaining global traction. For instance, a German research team is field-testing new module concepts that can be integrated into noise barrier walls alongside roadways and railways, aiming for cost-effective, power-generating solutions (pv magazine International). Similarly, Mitrex in North America is deploying PV noise barriers with a capacity of 1.2 MW per kilometer (Sustainability Journal). These barriers not only enhance highway aesthetics but also offer significant environmental benefits by generating emissions-free electricity.
According to research from the European Commission’s Joint Research Centre, the potential for vertical PV applications, such as PVNBs, is significant. These projects align with the European Solar Charter, which encourages innovative solar energy solutions integrated into various infrastructures. This approach not only boosts EU competitiveness but also diversifies energy sources (Environmental Science and Pollution Research).

Expert Opinion
Julius Sakalauskas, CEO of SoliTek, emphasizes the potential of these projects: “If the results meet expectations, such solar power plants could be installed in many sound-absorbing or reflective walls, especially in cases where they are newly built during the development of railway infrastructure.”
The integration of solar PV modules into noise barriers is a groundbreaking approach that simultaneously addresses noise pollution and renewable energy generation. SoliTek and Stalcorp’s projects in Lithuania exemplify this innovative use of solar technology, paving the way for sustainable growth in the energy sector. This dual-purpose infrastructure not only optimizes land use but also contributes to a greener and quieter urban environment.
