UAB SOLI TEK R&D

Their core work

Soli Tek R&D is a Lithuanian SME focused on photovoltaic (PV) module technology — specifically crystalline silicon (c-Si) solar cell manufacturing, module design, and performance optimization. They work on reducing the cost and improving the efficiency of solar energy systems, from conventional rooftop installations to building-integrated (BIPV) and vehicle-integrated (VIPV) photovoltaics. Their R&D covers advanced cell architectures like heterojunction (SHJ) and interdigitated back contact (IBC), as well as circular economy approaches to solar panel lifecycle management including recycling and second-life applications.

What they specialise in

How they've shifted over time

Their early projects (2015–2018) focused on PV manufacturing fundamentals — eco-efficient production processes (Eco-Solar) and material recovery from solar panel waste (CABRISS). From 2018 onward, their work shifted toward system-level performance, cost optimization, and circular business models, with SUPER PV addressing power electronics and data management, and CIRCUSOL exploring product-service systems for solar. The progression shows a company moving from component-level manufacturing R&D toward integrated PV solutions and sustainability-driven business innovation.

Moving toward integrated solar solutions that combine high-performance modules with circular lifecycle management — positioning for the growing demand for sustainable, cost-competitive European PV manufacturing.

How they like to work

Soli Tek R&D operates primarily as a project partner (4 out of 5 projects) but has demonstrated coordination capability, leading the SUPER PV project with its largest single funding allocation (EUR 544K). With 75 unique consortium partners across 16 countries, they maintain a broad European network rather than relying on a small set of repeat collaborators. Their strong preference for Innovation Actions (4 out of 5 projects) signals they contribute applied, near-market technology rather than early-stage research.

Extensive European network spanning 75 partners across 16 countries, reflecting deep integration into the EU photovoltaic research and manufacturing ecosystem. As a Lithuanian company, they bridge the Baltic/Eastern European PV sector with major Western European solar research hubs.

What sets them apart

Soli Tek is one of very few PV cell and module manufacturers in the Baltic states with active H2020 R&D involvement, giving them a rare combination of production capability and research credibility. Their portfolio uniquely spans the full PV value chain — from silicon cell architectures to module integration to end-of-life recycling — making them a one-stop partner for projects that need an actual manufacturer in the consortium, not just a research lab. Their coordination of SUPER PV shows they can lead multi-partner projects, not just contribute components.

Highlights from their portfolio

• SUPER PV
  Their only coordinated project (EUR 544K) — demonstrates leadership capability and deep investment in PV cost reduction and performance across c-Si and CIGS technologies.
• CIRCUSOL
  Represents their strategic expansion beyond manufacturing into circular economy business models for solar, including battery second-life — a forward-looking diversification.
• HighLite
  Their most recent project, targeting next-generation module concepts (BIPV, VIPV, shingle cells) for competitive EU PV manufacturing — signals their current technology direction.
