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.
Hevel Group has commissioned Chemal PV power plant fully based on heterojunction (HJT) modules with a capacity of 10 MW in the Altai Republic and has completed its solar parks construction program in the region.
Total installed PV capacity in the Altai Republic has reached 120 MW. The annual output of all solar generation in the region is estimated at 154 million kWh, which will provide more than 30% of the region’s consumption.
Earlier in December 2019, Hevel Group has commissioned Ust-Koksa PV power plant with a capacity of 40 MW, which has become the largest PV installation in Siberia and one of the largest HJT PV power plant in the world.
The first utility-scale grid PV power plant on HJT with a capacity of 20 MW was constructed by Hevel Group also in the Altai Republic in 2017. Since then the installed capacity of HJT PV power plants, deployed by Hevel in Russia has exceeded 200 MW.
Hevel Group is currently the largest industrial manufacturer of heterojunction PV modules in Europe and the only company in the world that successfully constructs HJT-based utility-scale parks. HJT technology helps to achieve the lowest possible cost of electricity generating and improve the economic performance of projects.
Since 2018, Hevel HJT cells and modules have been delivered to European and Asian countries. In 2019, Hevel’s factory started production of bifacial HJT PV modules and the company entered international PV installation market – pipeline of solar projects to be constructed with HJT modules in Kazakhstan until 2022 is 238 МW.
The Russian serial adventurer Fedor Konyukhov is preparing for one of his greatest challenges yet, for the first time in history crossing alone both Atlantic Ocean and Pacific Ocean exploring solar catamaran named NOVA. Route at the first phase will exceed 3 000 nautical miles that is equal to 25-day trip.
NOVA is being designed by a British boat designer who provided his services earlier for another three rowing boats of Fedor Konyukhov. The electrically driven catamaran will be constructed by Rannoch Adventure. Solar panels on flexible backsheet will be produced by Russia’s largest manufacturer Hevel Group at its R&D center in Saint Petersburg and placed on the top and sides of the boat. Photovoltaic cells should have water and UV resistance, with low specific gravity.
During his adventure Fedor Konyukhov will also conduct an environmental monitoring of both oceans, aiming to mark presence of plastic waste in ocean surface.
Hevel Group has exported 115 kW of bifacial HJT modules to Switzerland. The modules have already been installed on the roof of one of Coca-Cola factories in Vals municipality. This is the first bifacial PV modules based solar power generation facility put into commercial operation in Europe.
Bifacial HJT PV modules, oriented from the East to the West, enable to shift peak generation from noon to morning and evening hours, and generate up to 30% more power for the whole lifecycle compared to monofacial PV modules.
Bifacial modules have become one of the main trends on PV technologies market: in 2018, their market share achieved 20% and is keeping growing. Heterojunction technology is the most optimal for use in bifacial modules, as the bifaciality factor of Hevel’s cells exceeds 90%, which is notably higher than values of other PV technologies, including the most widely spread on the present-day market PERC technology, the bifaciality factor of which normally achieves 70%. It means that the rear side of Hevel’s HJT modules generates almost the same amount of power as the front one.
“Use of bifacial HJT modules in commercial projects confirms the fact, that PV power plants owners, when choosing between different technologies, are focused more on the final cost of the power generated throughout the whole modules lifecycle. Bifacial HJT modules are one of the most efficient from this point of view and enable to achieve the quickest possible return on investment”, – pointed out Igor Shakhray, CEO of Hevel Group.
Since 2018, Hevel HJT cells and modules have been delivered to European and Asian countries. In 2019, Hevel factory started production of bifacial HJT PV modules and the company entered international PV installation market – pipeline of solar projects to be constructed with use of Russian equipment in Kazakhstan until 2022 is 238 МW.
