Solarpro Selects LONGi Modules for Landmark 450 MWp Solar Project in Hungary

The Central European solar market continues to scale rapidly as Solarpro, a leading EPC contractor and part of the Renalfa Solarpro Group, has confirmed the selection of LONGi Solar as the module supplier for a 450 MWp utility-scale solar project in northern Hungary.

The project, located in Heves County, will be equipped with nearly 700,000 photovoltaic modules from LONGi’s latest Hi-MO 9 series, featuring advanced back contact (BC) cell technology. This technology is designed to deliver higher efficiency, improved temperature performance, and enhanced long-term reliability—key requirements for large-scale solar assets operating over multi-decade lifecycles.

Once commissioned, the solar farm is expected to produce approximately 470 GWh of clean electricity per year, enough to meet the annual power demand of around 106,000 households. The project will also deliver substantial environmental benefits, reducing carbon emissions by an estimated 415,000 tonnes annually.

The collaboration builds on a successful partnership between Solarpro and LONGi, following the completion of a 176 MW solar park in Romania last year. That earlier project laid the groundwork for continued cooperation on increasingly larger and more complex renewable energy developments across the region.

Solarpro has positioned itself as a specialist in hybrid energy projects, combining solar PV with wind power, battery energy storage, and hydrogen solutions. To date, the company has designed, delivered, and integrated more than 12 GW of solar capacity alongside over 4 GWh of battery storage, reflecting its growing role in Europe’s integrated energy transition.

The Hungarian project also aligns with broader regional investment plans. Earlier this year, the European Bank for Reconstruction and Development (EBRD) announced it is evaluating long-term, non-recourse financing to support the deployment of 450 MW of solar capacity across five adjacent sites in Heves, complemented by 250 MW / 1,000 MWh of co-located battery storage. This hybrid configuration is expected to enhance grid stability, improve dispatchability, and maximise the value of renewable generation.

As Hungary and the wider Central and Eastern European region accelerate the build-out of large-scale solar and storage, projects of this scale underline the growing importance of high-efficiency modules, bankable technology partners, and integrated EPC expertise in delivering reliable, future-proof renewable infrastructure.
