Roltec

What Roltec does

Roltec Sp. z o. o. is a Polish photovoltaic research, development, and manufacturing company headquartered in Żylice (Rawicz) with a registered office in Poznań. Founded in 2019 as a subsidiary of diversified group Grupa Wożaniak, the company specializes in CIGS (Copper Indium Gallium Selenide) thin-film solar modules — a technology in which it is the first producer at scale in Poland and Eastern Europe — alongside monocrystalline silicon bifacial modules based on TOPCon N-type M10 cells (BIJTHE60 series, 480 Wp, 22% efficiency). Its core technology platform combines proprietary light-pulse CIGS deposition methods (patent application P.427122), laser structurization on transparent ITO back contacts, and an integrated in-house laboratory with PVD systems, electron microscopes, and Class A+A+ solar simulators for materials characterization and device modeling.

Roltec generates revenue through hardware sales of CIGS and silicon photovoltaic modules, complete solar farm design and installation via third-party installers, commercial laboratory and pilot-line services (thin-film deposition, optical and electrical measurements, laser structuring, lamination), and licensing/royalty-equivalent participation in EU-funded research programs. Its go-to-market combines direct factory sales, the ATUM installer training and certification partnership, public tendering, and direct-to-consumer promotional campaigns at residential developments such as Osiedle KANVA in Nowa Sól. Customers span residential households, commercial enterprises and solar farm operators, R&D institutions, and construction developers.

The company is currently constructing the Solvoz CIGS factory in Wrocław — a 13,826 m² facility financed by ~24.4M PLN from the Polish National Recovery Plan, with planned annual capacity of 50 MWp and targeted 15% average module efficiency, completion expected by end of 2025. Roltec also produces the SolarBot autonomous photovoltaic cleaning robot and participates in three Horizon Europe consortia (SITA for >30% efficiency tandem CIGS/Si cells, Hi-BITS for transparent back contact CIGS, and LEEMONS for electron multiplication silicon cells), positioning it at the European frontier of next-generation PV research while commercializing its existing product portfolio.

Core offering

Roltec researches, develops, and manufactures CIGS (Copper Indium Gallium Selenide) thin-film photovoltaic solar modules, as well as monocrystalline bifacial silicon modules, at its facilities in Poland. The company also produces the SolarBot, an autonomous robotic cleaning and inspection device for solar farm collectors, and offers commercial laboratory and pilot-line services for thin-film deposition, characterization, and laser structuring. It is preparing to open the first CIGS thin-film solar module factory in Poland and Eastern Europe in Wrocław, with planned annual capacity of 50 MWp.

Product overview

Roltec is an independent R&D center specializing in photovoltaics, developing and manufacturing CIGS thin-film solar modules as its core product. Its portfolio comprises two main photovoltaic product lines: (1) CIGS thin-film modules — including standard CIGS modules from the Solvoz factory (under construction in Wrocław) and the BIJTHE60 bifacial glass-foil module — and (2) monocrystalline silicon modules (Bifacial M10) from the Si-Factory. Supporting the product lines, Roltec operates a Solar Factory (pilot CIGS production line with a proprietary patent, targeting 18% efficiency), a Si-Factory (automated silicon module line), and an in-house laboratory providing thin-layer deposition, optical and electrical characterization, and electron microscopy services. The company also manufactures the SolarBot autonomous cleaning robot for PV farms. Roltec participates in three EU Horizon Europe research projects — SITA (tandem CIGS/Si cells targeting >30% efficiency), Hi-BITS (transparent back contact CIGS), and LEEMONS (electron multiplication in silicon cells) — and offers commercial pilot-line services (laser structuring, lamination, efficiency testing).
