The combined model of cucumber production under the solar array of Mr. Chau Hon’s family brings a profit of 200,000 VND/day. Photo: Hong Diem Sustainable development model In 2018, the Green Innovation Development Center (GreenID) conducted research and put into practice a model combining agricultural production and solar power. According to GreenID, the model is designed according to the standards of rooftop solar power installed on construction sites, greenhouses planted under the guidance of Electricity of Vietnam (EVN) with a capacity of 45kwp installed on 400 square meter area. With a capital of over 900 million VND, the model will be completed and connected to the power grid in December 2020. To ensure plant efficiency, below the photovoltaic panels are designed at a distance of 1-2m. On average, the system produces 103kwh of electricity per day. In the first 3 months of 2021, 4,471kwh of electricity will be produced from this model (equivalent to 22 million VND). This is the first model with the participation of 3 parties (people, businesses and non-profit organizations). Accordingly, the enterprise will withdraw support capital in the first 10 years, then will hand over the entire system to GreenID and households participating in the model. After 20 years, the model will be handed over to households for management. The installation of solar panels above combined with growing vegetables and colors below not only creates additional income from selling electricity, but also makes the most of the arable land area, resolving conflicts in the use of resources. raw land. In fact, the crops grown underneath the electric panels have higher yields and better product quality. The model is expected to open up new directions for local agriculture. Truong Kien Tho, Deputy Director of the Department of Agriculture and Rural Development of An Giang province, said that this is a model that brings dual benefits, when combining agricultural production with solar power, helping people have clean electricity. , develop local agricultural production, and bring stable income for farmers. Open up a new direction Realizing the economic benefits that the model brings, Mr. Chau Hon (40 years old), from An Hoa hamlet, Chau Lang commune, Tri Ton district, An Giang province boldly and the research team developed the model on the land of family. From the beginning of 2021 up to now, the research team has cooperated with the project team and Mr. Hon’s family to experiment with water spinach and cucumber plants to calculate the appropriate level of cover under the solar panels and compare. with growing plants outside. The results show that, grown according to the above model, both plants grow well and give higher yields than those grown outside. “The research results of the pilot model will be documented to share with stakeholders and promote the process of promulgating appropriate policies for the development of a combined model of agricultural production and solar power. God. We will survey and replicate the model in areas with suitable conditions in An Giang province,” said Mr. Truong Kien Tho. Mr. Chau Hon excitedly said: “Compared to growing outside, cucumbers are grown under shaded solar panels, with very few pests and diseases, the plants grow well, the fruit setting rate is high, the fruit is even and the fruit is uniform. beautiful, yield higher than growing cucumber outside about 30%. On average, every day, I sell about 30-40 kg for 6,000 VND/kg, I earn about 200,000 VND, much more leisurely than rice production. Ms. Pham Thi Nguyet, Vice Chairman of Chau Lang Commune People’s Committee said, Chau Lang is a mountainous commune with special difficulties with more than 62% of the population being Khmer, the poverty rate is still over 3.4%. People mainly depend on agricultural production. The development of agriculture in combination with solar power has initially helped farmers change their traditional farming practices and adapt to new farming techniques to create dual incomes on the same land area. This is a model that can help many farmers get out of poverty and become well-off. “However, the replication of the model faces many difficulties due to high investment costs, the arable land of many households in the commune is far from the national power transmission line, so at present, this model has only been implemented. experience with Mr. Chau Hon’s family. With the benefits that the model brings, hopefully in the near future, there will be policies to develop this model” – Ms. Nguyet pondered.

A man named Ken invited two close friends to a deserted island far from the city and lived on his own for a month. Their purpose is to hide from the epidemic and explore the wild life like Robinson. Ken and his two best friends on a deserted island. Before landing on the deserted island, the 3 people prepared many tools including fishing rod, hoe, shovel, saw, tent, kitchen tools, spices and solar panels. They also carefully bought a live chicken in case they didn’t catch fish as soon as they got on the island. Arriving on a deserted island, the three of them set up their own tents, found a way to make a fire, every day went to the sea to catch grilled fish to eat, and even went to find hot water sources for a relaxing dip. When they feel bored, they find ways to entertain themselves, like exercising with weights made of driftwood, rocks, and rope. Or more simply, they blindfolded the type of fish they caught. The group of three work together to survive on the deserted island. Sometimes the group also encounters unexpected situations, such as the tent blowing up because of the strong wind, the mobile phone being soaked in water, unable to communicate. After living in the wild for a while, the three men returned to the mainland smoothly. Ken shares with everyone about his “Robinson experience”. He said the pristine life on the island gives him a feeling of excitement and eliminates the fear of contracting COVID-19, a feeling that is not possible in the city of Tokyo. Ken hopes that after the pandemic is over, he can return to the deserted island again and continue the adventure with more friends.

Research on recycling solar batteries contributes to boosting the weekly economy in Vietnam (Source: Internet). Solar power is an inevitable trend According to Decision No. 2068/QD-TTg issued by the Prime Minister on November 25, 2015 approving Vietnam’s renewable energy development strategy to 2030, with a vision to 2050, electricity produced from Solar power will reach about 35.4 billion kWh by 2030 and increase to 210 billion kWh by 2050. According to the Institute of Energy (Ministry of Industry and Trade), on average, a solar power source with a capacity of 1 MWp will generate nearly 70 tons of waste after about 20-25 years from the date the source starts generating electricity. Thus, according to forecasts, the amount of waste from these solar panels can reach millions of tons. Nguyen Van Hoi – Director of the Institute for Industry and Trade Policy and Strategy Research (Ministry of Industry and Trade) said that solar power is an inevitable trend of Vietnam’s energy industry, bringing many benefits to economic development. – society of the country and play an important role in reducing greenhouse gas emissions. In Resolution No. 55-NQ/TW on orientation of Vietnam’s national energy development strategy to 2030, with a vision to 2045, it is clear that it is necessary to develop synchronously, rationally and diversify types of energy. quality, prioritizing the exploitation, exhaustive and efficient use of renewable energy, new energy and clean energy; Use energy economically, efficiently, and protect the environment. Mr. Hoi said that the promotion of renewable energy development should be placed in the overall context of solutions, especially in the treatment of waste from the development of this energy source. Solar battery recycling solution Talking about the experience of processing and recycling solar panels of countries around the world, Mr. Dao Tran Nhan – Economic and Trade Advisory Association (VICETA) said, the Korean Government has issued new law “Extended Manufacturer Liability Program to take effect from 2023”. Accordingly, the Korean Government requires domestic manufacturers and importers to pay a recycling fee, which is expected to be US$1.04/kg. Meanwhile, Switzerland takes advantage of materials and components that are still valid to use and destroys those that are no longer worth using, using solar panels as a source of raw materials for making electric vehicle batteries (such as automobiles). , motorcycle). Proposing solutions for processing and recycling solar panels in Vietnam, Mr. Dao Tran Nhan suggested: For the group of policy solutions, it is necessary to develop regulations on downtime and storage. or recycle solar panels and have clear binding regulations between the parties. For the group of technological solutions, it is necessary to develop specific standards and regulations for each type of battery and develop a regulation to monitor and control the quality of solar cells. In addition, it is necessary to have a mechanism to encourage recycling as well as to develop sanctions to punish violations according to regulations. Dr. Le Huy Khoi – Institute for Strategic and Policy Studies of Industry and Trade also offered some solutions. Firstly, it is necessary to strengthen the inspection, examination and supervision of the collection and treatment of expired batteries. Second, the environmental protection responsibilities of owners of production, business and service establishments must “collect, classify, store, treat and dispose of solid waste in accordance with the law”. Third, research, develop and soon form a construction environment management department to regulate and supervise the final management of solar panels. Fourth, develop mechanisms and introduce policies to encourage investment in building solar panel recycling plants in Vietnam. Fifth, there should be financial and credit mechanisms and policies to support businesses in a practical way. Sixth, strengthen propaganda on the awareness of using, collecting and recycling solar cells effectively. Experts agree that, for Vietnam, the volume of waste from solar panels is quite small compared to the leading countries, however, to ensure sustainable development, the State needs to study soon to have appropriate policy and mechanism related to the collection and treatment of waste from solar cells. From a circular economy perspective, this can become an opportunity for Vietnam to develop the solar cell recycling industry in the future.

Mayflower 400 is a 3-hull ship, weighing 9 tons, 15m long, equipped with a fully automatic navigation system, AI technology and mounted many solar panels. During this journey, the smart ship, covered with solar panels, will study marine pollution and analyze the plastic in the water, as well as monitor aquatic mammals. With 80% of the world under the ocean undiscovered, the Mayflower 400 will have a lot to do. This self-propelled vessel will collect information and data, especially useful for commercial ocean shipping. Brett Phaneuf, the creator of the Mayflower 400 project, believes that the ocean is the place with the strongest impact on the global climate, so investing in this environmental research will be of great help in the fight against climate change. Rosie Lickorish, a new technology expert at IBM, partner in the Mayflower 400 project, affirms that the unmanned ship will bring a great advantage for exploring unprecedented environments, especially distant seas. Many technology and service providers, hundreds of individuals from many countries such as India, Switzerland and the US have participated in this project. Initially, the project was estimated to cost about $ 1 million, but the cost increased by about 10 times. The non-profit venture will provide the data collected by the project at a completely free price. The information could be used specifically for the future of the commercial shipping industry. It is expected that the ship will depart on May 15 after being licensed by British officials, the destination is Plymouth, Massachusetts (USA). This is the journey that the first Mayflower in 1620 carried a group of pilgrims to find a new land – America. Mayflower 400 will make this itinerary in 3 weeks. While the Mayflower 400’s trip was delayed due to the pandemic, Phaneuf said at least no one would get sick during the trip. “No one will feel bored or tired or sick during this uninhabited journey. So the ship can do science for as long as you like, ”he said from British port. Meirwen Jenking-Rees, a 21-year-old engineering student, tested the ship’s engine before it went to sea trials. Manufacturing is automated from the robotic rudder to the solar-powered diesel generator in a year. Building an “intelligent captain”, artificial intelligence on board, takes even longer because computers have to learn to identify maritime obstacles by analyzing thousands of images. The Mayflower 400 must also be taught how to avoid a collision and set sail for the first time. Robot and software engineer Ollie Thompson says that, by running a number of “scripts”, the ship can learn “what is good action, what is bad, what is safe and what is not”. . So if it makes a mistake, the boat can repair itself and learn from experience. The automatic ship uses “eyes” and “ears” – a complex system of six cameras and radar – to continue self-study. Due to the lack of regulations surrounding the deployment of unmanned boats, the Mayflower 400 has yet to be tested in rough seas or storms, a situation Jenking-Rees describes as a “worst case scenario”. In the simulated settings, however, the smart boat was faced with waves as high as 50 meters. The boat’s artificial intelligence will play an important role in conducting scientific experiments, Lickorish explained. The group will monitor the ship 24/24 from the UK, ready to intervene remotely in case of danger.

Previously, Japan’s top brands have, in turn, eliminated or reduced the scale of TV production, an area that is considered the spearhead of the electronics industry in this country. Now it is Panasonic’s turn to follow in the footsteps of its “seniors”. Accordingly, the company will continue to produce high-end TVs, but mainly to serve the Japanese market. In addition, the company will also consider consolidating or shrinking TV production locations at home and abroad. Previously, Panasonic used to be one of the major TV manufacturers with 10% of the global TV market share, but since low-cost competitors from China appeared, the company gradually lost its appeal. It is known that the TV business and production accounts for less than 10% of Panasonic’s total revenue. Besides TVs, Panasonic also sold its semiconductor business to Taiwan’s Nuvoton Technology as well as withdrew from manufacturing liquid crystal displays and solar cells. Currently, Panasonic owns 8 companies in Vietnam, including Panasonic System Networks Vietnam located in Thang Long Industrial Park, Dong Anh, Hanoi; factories producing refrigerators, washing machines, R&D centers, sales departments are all over the country, from Hanoi, Da Nang, Ho Chi Minh City, Can Tho … synthetic

In Ninh Thuan province, the Cyclic Energy Solution Company (CAS Company) is applying the model of goat farming and experimental planting of trees under panels at 3ha large solar farm. However, Mr. Tran Anh Dong, Director of CAS Company, said: “The company’s main revenue is from solar power, while the revenue from agricultural production is still low. Currently, the company is still struggling in finding high-yield crops suitable for the conditions to be planted under solar panels ”. According to Nguyen Quoc Khanh, the model of solar power combined with agriculture has great potential, both increasing the efficiency of land use and creating more income for farmers. However, at present, this model still has many limitations such as: Not meeting farm economic criteria, no support mechanism for solar power, lack of information on suitable crops, no technical guidance, lack of practical model … In order for this model to really promote its effectiveness, the State needs more mechanisms and policies to help businesses overcome the above problems.

Professional solar battery cleaning worker for a project in the city. Ho Chi Minh Meanwhile, according to engineer Thanh, the current method of cleaning the panels is mostly done by investors, most of them are using water, available facilities and using a hose to wash them, this method is not technically correct. in terms of maintenance, because many areas have water contaminated with alum, hard water, there is a lot of organic matter, more dissolved metals… leading to further damage to the panels. “The effectiveness of the project apart from equipment, materials, installation techniques, the operation and maintaining the efficiency of the system is related to the cleaning of the panels. Keeping the panels clean is the key to maximizing output, increasing economic efficiency for investors, ”Thanh said. Solar power is booming in Vietnam, especially household investment packages, concentrated in remote and island areas in the South. According to the Vietnam Electricity (EVN), by the end of 2020, the total capacity of renewable energy sources will be 17,430 MW (up 11,780 MW compared to 2019) and accounting for 25.3%. . In which, there are about 8,000 MW of rooftop solar power and more than 8,400 MW of large farm solar power. Thus, according to investors’ calculations, the whole country currently has no less than 30 million solar panels operating in the whole system and will increase when many projects are under construction and about to be operational. Seeing this potential, a number of businesses in the South have added new services, which are professional cleaning of solar panels and package maintenance for solar power systems. the investors. Mr. Le Tran Khanh Vy – General Director of Nhat Hung Environmental Technology Co., Ltd. (Thu Duc City) – said that in the face of more and more investors installing solar equipment, the company opened more professional solar battery cleaning service, currently hundreds of customers across the country have signed contracts to participate in cleaning and maintaining solar power systems with this package. To meet the needs of customers, especially solar power investment packages in industrial form, the company is forced to professionalize by producing standard cleaning solutions, investing in specialized cleaning equipment. and has a team of professional staff in charge. “The solution that the company offers is to keep batteries clean by cleaning them regularly and properly; Check the water source, if the water source is contaminated with alum, hard water, contains a lot of organic matter, lots of dissolved metals, it must be handled; choosing a cleaning solution specialized for cleaning panels, because now there are domestically produced products with appropriate and safe prices, ”said Mr. Vy. On the market, there are specialized solutions for cleaning solar cells According to electricity experts, at present, many solar power projects are invested billions of dong, even more money, but the stage of battery cleaning and system maintenance is less concerned by investors properly. This leads to a reduced lifespan of the building, especially the heat collection efficiency of the panels is low, while if cleaned and maintained properly, the economic efficiency is not small. Mr. Huynh Duc Tien, living in Hoc Mon district, city. Ho Chi Minh has just signed a package contract with a company specializing in solar battery cleaning and maintenance of the solar power system with an investment of more than 1.2 billion VND nearly 2 years ago. Mr. Tien said that the cleaning company has specialized solutions, tools and techniques, so it is handed over to them for management because the cost is not much and it saves time.

The talented Hungarian architect Tamás Bene has designed a lovely boat house for a young couple from Budapest. The boat house is originally a local fishing boat, anchored at Lake Tisza – an artificial reservoir located in a 7,000-hectare nature reserve, home to wildlife including more than 100 species of birds together. The ship is made of two main materials, aluminum and treated wood. When going into practice, the designer develops the idea based on the needs and wants of the couple. And the most important thing is to design boats in harmony with nature and in harmony with the surrounding environment. To get as close to nature as possible, the boat has a large panoramic window, sliding doors that create a seamless connection to the starboard deck. The interior uses red wood and heat-resistant wood, including a kitchen, dining room with two benches and a table. At night, the table can be lowered by chair to form a unique, space-saving and multi-purpose bed. Each object placed on the boat has its own implications, not redundant by small, narrow space. The boat house also has two roof-mounted solar panels that power electrical appliances, including front and rear headlights, lights, and a small refrigerator. “Drinking water is taken from a 20 liter bottle and can be delivered to the tap with a foot operated pump, so no electricity is needed,” explained the architect. The boat itself is powered by a combustion engine with a capacity of 9.9 horsepower, allowing the operator to navigate around the shallow, winding canals of Lake Tisza./.

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. Households in Luc Ngan district install solar power system on the roof. Photo provided by CTV. 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.

Stemming from the research on the model combining agricultural production and solar power in 2018, the Green Innovation and Development Center (GreenID) continues to do field research to pilot the model in An Giang province. The selected place is the cultivated land of Mr. Chau Hon’s family, Khmer household in An Hoa hamlet (Chau Lang commune, Tri Ton). The model was implemented by GreenID and Climate Sense Co., Ltd. (Climate Sense) from May 2020, with the support of the Management Board of the Sustainable Energy Development Project in An Giang province, Department of Agriculture and Development. Tri Ton district rural area and Chau Lang Commune People’s Committee. The model is designed according to the standards of rooftop solar power installed on construction works, tree-growing houses and instructions of EVN (Vietnam Electricity) with a capacity of 45Kwp, installed on an area of ​​400m2. of Mr. Chau Hon’s family. The model is completed and the grid is connected in December 2020. To ensure the efficiency of the plants underneath, the solar panels are designed with the right spacing, to ensure the growth of the plant variety. This is considered the first model with tripartite cooperation (people, businesses and non-profit organizations). The benefit sharing mechanism is discussed, agreed and harmonized among the participants. Agricultural production and sub-system farming activities are calculated and tested as soon as the system is completed with a number of short-term crops to assess growth and economic efficiency of the system. paradigm. The solar model associates agricultural production with double efficiency According to GreenID, the profit from the model will be divided among the parties according to the proportion of capital contribution invested. The disbursement period for Climate Sense is in the first 10 years because Climate Sense capital is meant to support initial investment. After 10 years, the whole system will be handed over to GreenID and households for management and use. After 20 years, GreenID will hand over to households full ownership. This model is expected to bring many multilateral financial benefits to the participants and facilitate as well as a typical model to call for more investors to expand. Farmers are excited Since commissioning in early 2021, the power generation portion is monitored remotely on the phone application. As recorded, the sunniest day, the model produces about 246Kwh of electricity and the lowest is 43Kwh on the day. On average, the system produces 103 kWh of electricity per day (as of April 7, 2021). Every month, electricity will record the indexes and payout on the amount of electricity sold to the investor’s account. From January to March 2021, the project has sold more than 4,471 kWh of electricity, equivalent to over VND 22 million. In this joint venture model, all participants benefit from the project. All profits earned from the sale of electricity to EVN will be distributed to the parties to the investment according to the profit sharing structure agreed upon by the parties in the joint venture cooperation contract. Joining the model, Mr. Chau Hon’s family and the project planted some new crops to test new crops for research. From January to April 2021, the research team collaborated with the project team and farmers to experiment with water spinach and cucumber to calculate the suitability of plants under solar panels and compare them with planting. outside. In fact, plants in the shade under solar panels grow well because they retain moisture, avoid direct sunlight due to extremely sunny weather and improved farming techniques. “I planted cucumber from February to 2021, the plants grown in a greenhouse under the panels outperform the control field outside, the fruiting rate is quite stable. Currently, my family harvests more than 30kg of cucumber per day. The fruit has a nice design and is long, fresh and delicious, highly appreciated by customers ”- Mr. Chau Hon said excitedly. Deputy Director of Department of Agriculture and Rural Development Truong Kien Tho said that the combination of agricultural production and solar power is a new model, showing initial efficiency. “When looking at the pictures of the panels covering the agricultural land, many people think it is impossible to cultivate. However, when choosing suitable crops, productivity and quality are higher. In the same arid land, farmers can keep an income from farming while also earning a monthly electricity bill. This is a model that can help many farmers to escape poverty sustainably and get better-off ”- Mr. Tho assessed. The model of installing solar cells combining agricultural production below helps generate additional revenue from selling solar power, making the most of arable land to increase income, and reduce conflicts in use. use of land resources. Some crops benefit from increased coverage, resulting in higher yields and better product quality
