A large-scale solar development in Hungary has secured its core technology supplier, as engineering and construction specialist Solarpro awarded a major module contract to Chinese manufacturer LONGi. The project, located in Heves county, is set to become one of the largest single solar installations planned in the country. Under the agreement, LONGi will supply modules from its Hi-MO9 series, featuring back-contact cell architecture designed to maximize efficiency and output. Nearly 700,000 panels will be installed, forming a photovoltaic system with a total capacity of 450 MW.
Once fully operational, the solar facility is expected to produce around 470 GWh of electricity annually, enough to cover the annual demand of roughly 106,000 households while reducing carbon dioxide emissions by an estimated 415,000 tons per year.
The project builds on an existing cooperation between the two companies. In 2024, Solarpro and LONGi collaborated on a 176 MW solar park in Studina, Romania, laying the foundation for this significantly larger project. Solarpro, part of the Vienna-based Renalfa Solarpro Group, specializes in complex energy solutions integrating multiple technologies. Its portfolio includes solar and wind generation, battery storage, and hydrogen-related systems, with over 12 GW of solar capacity and more than 4 GWh of energy storage designed, built, or integrated to date.
