What is TOPCon? Explained simply, in 5 steps
Tunnel Oxide Passivated Contact explained in 5 steps: tunnel oxide, doped polysilicon and a passivated rear contact.
European PV cell manufacturing
SOLYWATT ROMANIA SRL is planning a TOPCon+ photovoltaic cell factory in Galati, with a capacity of 1.17 GW.
SOLYWATT ROMANIA SRL is a Romanian project for European photovoltaic cell manufacturing. Our goal is to support Europe's energy independence through local production, local skills and research in Romania.
We focus on TOPCon+ technology, a modern solar cell architecture, and on an industrial presence in Galati.
We are planning a TOPCon+ photovoltaic cell factory in Galati, Romania, with a capacity of 1.17 GW.
European manufacturing means shorter supply chains, local added value and a concrete step toward energy independence.
Planned photovoltaic cell production capacity.
Modern cell technology for the European market.
Industrial location in Romania, on the Just Transition path.
The Galati project follows Just Transition principles: local jobs, new skills and a clean industry for the region.
We invest in people: training, technical skills and an industrial base that stays in Romania.
SOLYWATT ROMANIA's research and development activity is in Romania, in Bucharest. This is where we build the technical competence that supports production in Galati.
