In 1Q 2020 Hevel Group has launched production of heterojunction solar cells based on M2+ silicon wafers. A slight area increase has allowed to raise the HJT solar cell peak power up to 5,88 Wp with maximum cell efficiency rate of 23,8%, while maintaining an average of 23,3%.
At the same time Hevel HJT modules have retained their respective dimensions, while receiving a boost in yield and efficiency thanks to the M2+ transition. HJT modules with increased power output of 330 Wp and 390 Wp were introduced to existing glass-backsheet 60-cell and glass-glass 72-cell module series, respectively. Enhanced performance combined with minimized annual degradation, better yield in hot climate conditions and aesthetic appearance make these HJT modules a solid pick for any project, where efficiency matters.
Thinking several steps ahead Hevel R&D centre in Saint Petersburg, Russia, has already started testing M6 wafer-based HJT solar cells, designed for multi-busbar / multi-wire interconnection technology. Hevel Group expects the peak power for HJT solar cell based on M6 silicon wafer, which is 6% larger than M2, to reach at least 6,71 Wp. Hevel Group believes that in the coming years there will be a surge in market demand for PV modules with highest possible performance and Hevel will make sure that such a product is available to its partners and clients.
Hevel Group announced completion of ramp up works at its factory that resulted in expansion of heterojunction solar modules and cells production from 260 to 340 MW. The company plans to reach the full manufacture production in the third quarter of 2020.
Production capacity of the Hevel factory increases due to the following factors:
- Installation of additional equipment for plasma-enhanced chemical vapor deposition.
- Realization of our R&D program that allows to increase physical vapor deposition equipment capacity.
- Increase of production line capacity by manufacturing activity optimization.
The company creates ten new highly qualified jobs at the plant in order to reach production plans. Nowadays there are more than 600 people working there.
Hevel finished the second part of the plant modernization in June 2019 expanding yearly solar modules production capacity from 160 to 260 MW. The company also started production of 72-cell bifacial HJT modules with a capacity of up to 385 W not considering the bifaciality factor. Capacity of the modules considering the bifaciality factor is more than 440 W.
Russia’s largest PV cell and module manufacturer Hevel Group commissioned in the southern Ural region Bashkortostan 10 MW solar plant backed by an 8 MW battery storage system.
The solar-plus-storage facility will be operated as stand-alone PV system connected to the grid. The new plant was constructed in Burzyan municipality (Bashkortostan region) with more than 16000 population. The long-distance transport of electricity is facilitated through a 100-km single-circuit transmission line with a one-end substation. The hybrid solar plant is designed to improve the larger grid’s resilience and will switch to stand-alone mode in an emergency power outage.
“This is the first utility-scale solar-plus-storage project in Russia that provides up to 80 percent of energy consumption in one municipality, improving power supply quality for households, hospitals and schools,” told CEO of Hevel Group Igor Shakhray.
In 2019 the solar module plant Hevel in Novocheboksarsk produced 698,000 high efficiency heterojunction solar modules with a total capacity of 229 MW, fulfilled the planned targets comprehensively.
In 2019 the solar modules were delivered to the solar power plants: Elshanskaya PV plant (15 MW) and Dombarovskaya PV plant (33.5 MW) in the Orenburg Region, Yashkulskaya PV plant in the Republic of Kalmykia with a capacity of 33.5 MW, at Ust-Koksinskaya PV plant (40 MW) and Chemalskaya PV plant (10 MW) in the Altai Republic, as well as on partner projects: in the Republic of Buryatia (45 MW), in the Orenburg region, the Svetlinskaya PV plant (30 MW) and Novosergievskaya PV plant (15 MW). There were started the shipping of products to the Republic of Kazakhstan for the construction of the Nura PV plant with a capacity of 100 MW. Part of the production is aimed at implementing energy supply projects for industrial infrastructure and private households.
In June 2019 the modernization of production facilities in the plant was completed, the annual output of solar modules increased from 160 to 260 MW. Also in June the Hevel plant began producing bifacial solar modules from 72 cells, the power of which, taking into account the bifacial coefficient, reaches 420 W. In total, these products occupy about 35%.
Field tests of bifacial heterojunction modules showed that their specific output exceeds the production of single-sided modules by 5-12% on sunny days and up to 20% on cloudy days and in winter, depending on lighting conditions.
During the year the company continued to improve the quality characteristics of cells and modules.
At the end of 2019, the average efficiency of cells reached 22.7%, and the maximum efficiency of cells in production exceeds 23.2%. By increasing the efficiency of the cells and optimizing the assembly technology, the average power of single-sided modules reached 316 W, bifacial without taking into account the coefficient of bi-directionality – 375 W.
In connection with the growth of production volumes in the plant were created more than 130 new jobs.
