Recently, the development of solar power (solar energy) is being encouraged to invest and build to take advantage of clean energy sources, reduce pressure on the electricity industry. However, there is no specific solution to the problem of dealing with solar panels when they expire.
Replication support
Solar power is being encouraged to use, contributing to creating more clean energy sources, towards the goal of green and sustainable electricity development. Immediately after the Politburo issued Resolution 55-NQ / TW, on February 11, 2020 on the national energy development strategic orientation, the provincial People’s Committee directed the Department of Industry and Trade to coordinate with related agencies and units. research, advise and propose rooftop power development. Department of Industry and Trade proposed the Ministry of Industry and Trade to supplement the planning for 2 solar power plants in Viet Yen and Yen The; solar power projects in industrial zones and clusters with a total capacity of 2,320 MVA.

Mr. Nguyen Duc Hoan, Deputy Director of the Department of Industry and Trade, informed that although power companies stopped connecting and purchased solar power in the case of installation after December 31, 2020, it is only temporary. In general, the State has a mechanism to develop solar power with many attractive policies such as: Buying solar power at high prices, purchasing time lasts 20 years, commercial banks facilitate maximum loans from 70 -80% value of solar power projects in a period of 5-8 years. With the above advantages, many individuals, businesses (DN) and units have been encouraged to take advantage of this energy source. By the end of December 31, 2020, the whole province had 607 customers installing rooftop solar power system with a total installed capacity of 15,936.46 kWp. In which, 10 are enterprises with a total installed capacity of more than 100 kWp or more, the rest are households and non-business units. It is known that since 2017, the province has implemented rooftop solar power development programs in a number of different forms, but mainly supported the installation of pilot models, demonstrations for the purpose of evaluation and replication. power saving; At the same time, it will support 10 state agencies to participate in the use of solar power in the near future. At this time, the Department is assigning the Center for Industrial Promotion and Trade Promotion to assist the People’s Committee of Luc Ngan district to install solar bulbs in the district People’s Committee square. The results and orientations of the province show that the development of solar power in the locality is increasing in both quantity and scale, especially in enterprises. This policy, in the immediate future, has brought about a clear effect, contributing to reducing the pressure, saving costs of developing transmission lines and using clean energy sources. Solve the expired solar battery problem The electricity obtained from the sun is clean energy, but when the solar panels expire, they become garbage, which is very dangerous. According to specialized agencies, the average service life of solar panels ranges from 10 to 20 years, depending on the location and the environment where it is installed. However, the handling of expired panels so far has not had a specific direction. A representative of the leadership of the Department of Industry and Trade – a permanent unit to advise on this content, said that in a written consultation with the Provincial People’s Committee on the development of rooftop power projects, the unit has not yet proposed specific measures for Dispose of the panels when the battery expires. By the end of December 31, 2020, the whole province had 607 customers installing rooftop solar power system, total installed capacity was 15,936.46 kWp. In which, 10 enterprises with a total installed capacity of more than 100 kWp or more, the rest are households and non-business units “. Mr. Nguyen Duc Hoan, Deputy Director of Department of Industry and Trade Discussing this issue with Mr. Nguyen Ba Trinh, an expert from the Department of Environmental Protection (Department of Natural Resources and Environment), it is known that the solar cell when its expiry date is hazardous waste. The disposal of this waste is very difficult, if not handled properly but burying in the wrong regulations, it will pollute the soil and water environment due to generation of heavy metals or toxic emissions. In the event of a fire the battery is capable of harming human health. There is only one unit in the province, Hoa Binh Industrial Waste Treatment and Recycling Joint Stock Company (Yen Dung) that is eligible to handle this type of waste, but the scale of treatment of the enterprise is small. Mr. Trinh also added that, according to Article 68 of the Law on Environmental Protection, the environmental protection responsibilities of owners of production, business and service establishments must “collect, classify, store, treat and dispose of. disposal of solid waste in accordance with the law ”, that is, the investor is responsible for handling the battery when it expires. Therefore, it may be worrisome that, after the expiration of its use term, households dispose of solar panels with domestic waste, do not hire the unit to collect, transport and dispose of it. Unattended authorities. Or the owner of the panel is not able to handle or dispose of the panel into the environment. Thus, solar power development associated with environmental sustainability has not been paid attention. New authorities focus on planning and encouraging expansion to reduce pressure on the national grid without giving specific solutions to handle solar cells when they expire. Some comments said that the functional agencies, especially the Department of Industry and Trade, the standing unit to advise on this content, should soon offer solutions to handle solar batteries after the expiration of use.
