LONGi Solar has deployed 54.1 MW of Hi-MO 9 back contact (BC) modules at Romania’s largest retail infrastructure solar park, CEF Chișineu-Criș in Arad County. Developed for NEPI Rockcastle’s subsidiary SOLPOWER Energy and engineered by EPC partner Enevo Group, the project highlights BC technology’s crucial role in Romania’s grid-scale renewable transition.
The facility features 84,000 Hi-MO 9 modules, designed to maximize energy autonomy for NEPI Rockcastle’s retail properties. Construction began in January 2025 and is on track for grid connection in Q4 2025. With 24.8% module efficiency and excellent temperature resilience, the plant is optimized for Romania’s continental climate. It is expected to generate approximately 70,171 MWh annually—enough to power 29,300 homes—and avoid 21,100 tons of CO₂ emissions each year. The project will also create over 100 local jobs and prioritize regional contractors, supporting the local economy.
“This project exemplifies how BC technology transforms utility-scale solar into a reliable backbone for major infrastructure. Hi-MO 9’s unmatched performance ensures NEPI Rockcastle’s portfolio achieves energy stability” said Mirel Jarnea, Country Manager Utility Scale Business Unit of LONGi.
Eduard Meiloiu, Executive Director Renewables BU of ENEVO said “Our collaboration with LONGi has been seamless from start to finish, reflecting a truly efficient and aligned partnership. BC technology brought clear engineering advantages — from higher efficiency and improved thermal performance to long-term reliability. Our engineering team greatly appreciated the precision and flexibility of the solution, which enabled us to deliver a robust project tailored to local conditions and fully aligned with Romania’s sustainability goals.”
