European solar PV manufacturers 3Sun, Holosolis, and MCPV announced multi-gigawatt production expansions totaling at least 3 GW, with public co-financing secured from European Union institutions. 3Sun is scaling its Catania facility to 3 GW capacity, while Holosolis plans an integrated multi-GW site in France, and MCPV is developing a project in Spain. These expansions represent the first concrete manufacturing projects moving forward under the Net-Zero Industry Act (NZIA) framework, which reserves specific market segments for domestic producers. The European Commission's regulatory infrastructure, including NZIA and the Industrial Acceleration Act (IAA), provides the policy framework enabling these developments through resilience-weighted tenders and sustainability criteria. Public co-financing signals strong institutional support for reshoring PV manufacturing capacity across Italy, France, and Spain. The projects are expected to close the 10 GW gap between current European manufacturing capacity and the NZIA-reserved 18-35 GW annual demand by 2030.
