Metsolar, a Lithuania-based manufacturer of customized solar modules, has joined the EU-funded IBC4EU project, which aims to develop cost-effective and sustainable bifacial Interdigitated Back Contact (IBC) solar cell and module technology on a pilot line level. The project is part of the Horizon Europe programme and contributes to strengthening the European photovoltaic (PV) value chain.

Metsolar is an innovative company active in the constantly growing Building-Integrated Photovoltaics (BIPV) market. Their goal is to develop solar modules that blend seamlessly into buildings—both visually and functionally—while keeping an affordable price and high performance.

As part of IBC4EU, Metsolar is reconfiguring its pilot production line to manufacture advanced BIPV modules based on IBC and TOPCon solar cells. These next-generation technologies offer high power output (Wp/m²) and a clean, uniform appearance, which are essential features for modern BIPV applications. 

Metsolar is also working on the optimization of production processes, including industrial stringing and busbar painting, to improve module aesthetics and reduce production costs. The company is exploring a range of color options to increase design flexibility for architectural integration. 

As part of the IBC4EU project, Metsolar is producing a series of IBC- and TOPCon-based BIPV modules for comparative analysis. These modules will undergo quality and safety testing, including IEC certification and fire resistance evaluation, in collaboration with accredited laboratories such as Protech. The company is also submitting its full IBC module range for pre-certification within the project framework. 

In another project activity, Metsolar is integrating a machine vision system into its pilot line to assess the visual quality of BIPV modules during production. This system will generate data to train AI and machine learning models developed by project partner ISCK, enabling automated module classification and consistent visual standards across batches. This also aims to reduce the number of B-class modules delivered to end users. 

Metsolar’s involvement in the IBC4EU project reinforces its long-term commitment to innovation in BIPV and to the broader industrialization of high-efficiency solar technologies in Europe.

This project has received funding from the Horizon Europe Programme for Research and Innovation (2021-2027) under grant agreement No 101084259.
