Hevel manufactory in Novocheboksarsk produced 698K of heterojunction (HJT) solar modules with a capacity of 229 MW in 2019, fulfilling all target figures.
Solar modules were installed in 2019 at the following Hevel PV power plants: Elshanskaya PV power plant (15 MW) and Dombarovskaya PV power plant (33,5 MW) in Orenburg region, Yashkul PV power plant with a capacity of 33,5 MW in the Republic of Kalmykia, Ust-Koksa PV power plant (40 MW) and Chemal PV power plant (10 MW) in the Altai Republic. The modules were also installed at the Hevel partners’ solar plants in the Republic of Buryatia and Orenburg region. Hevel began shipping it solar products to Kazakhstan for Nura PV power plant. Some of the modules were used in the projects aimed to commercial and private households energy supply.
In June, 2019, Hevel has expanded production capacity to 260 MW and started production of 72-cell bifacial HJT modules with a capacity of up to 420 W.
Field tests carried out at the plant showed that bifacial modules output exceeds monofacial modules capacity by 5-12% on sunny days and by 20% in winter and cloudy weather.
The fab continued increasing quality of the produced solar cells and modules. By the end of 2019, the average efficiency of cells reached 22.7%, and the maximum efficiency of cells in production exceeds 23.2%. Due to cell-efficiency raise and technology optimization average module-efficiency has reached 316 MW for monofacial HJT modules and 375 W at STC for bifacial modules not considering the bifaciality factor.
