Trinasolar targets up to 1.6 GWh of BESS deliveries in Italy in 2026

Trinasolar plans to supply between 1.4 GWh and 1.6 GWh of BESS capacity in Italy this year, according to Gonzalo de la Viña, the company’s president for Europe, Latin America and the Caribbean.

He said the estimate reflects products scheduled for delivery rather than signed contracts.

De la Viña told pv magazine Italia that Italy is Trinasolar’s second-largest BESS market after the United Kingdom and its third-largest solar module market after Spain and Germany.

He said the company is awaiting the results of Italy’s MACSE storage capacity auction after the application window opened this week. He added that Trinasolar expects to supply about 2 GW of solar modules in Italy this year. The company estimates its market share at between 15% and 20% in both Italy’s BESS and solar module markets.

De la Viña said Trinasolar is now assessing the possibility of building a BESS manufacturing facility in Europe but has no plans to establish a solar module factory on the continent. He said manufacturing costs in Europe remain 30% to 50% higher than in China.

The executive said France and Spain are the leading candidates for a future BESS factory, following an assessment of political, economic and labor market conditions. He said Germany would be too expensive, while concerns over Hungary’s political environment have reduced its attractiveness.

De la Viña said Europe continues to lack a competitive battery supply chain and faces higher labor and operating costs, making it more economical for Trinasolar to import materials from China and Southeast Asia even after import duties.

He added that the company is diversifying its supply chain by sourcing power conversion systems from Spanish manufacturer Power Electronics while also offering its own China-made PCS products.

As part of its European strategy, Trinasolar also holds what it described as a small stake in the 5 GW HoloSolis solar manufacturing project in France, where it is providing technology licensing and technical support. The project aims to begin production in the third quarter of 2028, following completion of its current fundraising rounds.
