ML System – Industrial Excellence and BIPV Expertise

The quality of the PVT ML 450/1200 module is based on the technological and manufacturing capabilities of ML System S.A. — the Polish leader in building-integrated photovoltaics (BIPV) and a provider of advanced PV technologies.

ML System’s position results from a consistently implemented development strategy based on:

  • continuous development of practical innovations,

  • a strong research and development base,

  • a recognized brand and a broad portfolio of advanced technologies,

  • the ability to industrially manufacture PV and BIPV modules meeting high technical, aesthetic, and functional requirements.

The company operates its own advanced R&D center, where unique products based on proprietary technologies are developed, including the world’s first production line for printed photovoltaic cells. ML System’s innovativeness is confirmed by an extensive patent portfolio and a wide range of products that constitute a real alternative to traditional building materials — offering, among others, high thermal insulation, airtightness, and acoustic properties.

In parallel, ML System is developing breakthrough technologies at the intersection of photovoltaics and quantum physics, such as Quantum Glass, 2D Glass, and Active Glass, including the world’s first production line for transparent glass with a quantum coating capable of generating electrical energy. This direction aligns with the strategy of the so-called “new quantum era,” enabling the company to maintain a long-term technological advantage.

As a result, the PVT ML 450/1200 module combines proven technology, industrial-grade build quality, and long-term operational safety, addressing the needs of stable and scalable PVT installations.
