Budapest,Hungary,15 December— European leading EPC and O&M contractor of PV and BESS systems Solarpro is building what will be the largest solar power plant in Hungary, using photovoltaic modules from industry leader LONGi. Located in the northern county of Heves, the 450 Megawatt project will deploy nearly 700,000 modules from LONGi’s ultra-efficient Hi-MO9 product series. The plant also marks an expansion of Solarpro’s partnership with LONGi, following a 176 MW solar park the two companies partnered on last year in Studina, Romania.
Solar park’s output can cut CO2 emissions by 415,000 tons per year
With a peak capacity of 450 MW, the new plant is expected to generate 470 Gigawatts-hours (GWh) per year, enough electricity to power around 106,000 households annually. Replacing fossil fuel use, the project’s clean energy output can reduce greenhouse gas emissions by 415,000 tons every year, the equivalent of removing over 100,000 gas-powered cars from the road.
Solarpro chooses LONGi’s “back contact” technology for watershed project
The Hi-MO9 solar module offers the plant the advantage of LONGi’s back contact (BC) technology, a complex engineering and design upgrade that reduces micro-cracking in the wafer by 50% compared to traditional modules, increases electricity generation by up to 8%, and safeguards the module’s long-term performance – particularly under the sometimes-tough conditions present in northern rural Hungary, like high heat, dust, and cloud cover. The BC module’s benefits also compound over the three decades of the product’s lifespan, meaning Solarpro’s new plant can anticipate more efficient production as well as more cost-effective, more reliable clean power for the area’s energy consumers.
Leon Zhang, President of LONGi Europe said: “It’s an honour to supply Solarpro the modules for this landmark Hungarian project. In partnering with one of Europe’s leading project developers, we’re able to contribute to the region’s clean energy future and, at the same time, to set a new technological standard. At LONGi and Solarpro, we’re both committed to innovation and long-term sustainability, so we’re looking forward to continuing the cooperation.”
Krasen Mateev, CEO of Solarpro said: “We are proud to join forces with LONGi once again on this major project in Hungary. At 450 MW, the solar plant will be Europe’s largest back-contact installation and a milestone in Solarpro’s mission to deliver reliable, high-efficiency clean energy across the region. The advanced technology of the Hi-MO9 was a clear choice to maximize the project’s performance and long-term reliability.
By combining Solarpro’s EPC expertise with LONGi’s innovation, we are setting a new standard for utility-scale solar in Europe.”
