Polaris solar PV net news: by the year 2030, China abandoned solar module produces 1.45 million tonnes of carbon steel, 1.1 million tons of glass, 540,000 tons of plastic, 260,000 tons of aluminum, 170,000 tons, 50,000 tons of copper and silicon and 550 tons of silver.
Europe has the most mature supervision system of PV recycling, other parts of the world, there is no provision to force recycling of photovoltaic modules.
On their roof mounted photovoltaic modules, access to solar power is becoming more and more popular. These low-carbon pioneers ever, decades later, these big PV module want to do?
Last ten years, China has become the global PV installed capacity of First Nations, policies and regulations on PV module recycling is blank. Study on PV module recycling companies and institutions are few, even for environmental organizations, this is a topic that has not yet started to pay attention.
According to the international renewable energy agency, the International Energy Agency photovoltaic system project report, in 2014, the abandoned PV modules for less than 1 per thousand of the electronic waste; and by 2050, it will reach 78 million tons, global commodities market will be worth $ 15 billion.
“The garbage of the PV modules will increase sharply in the near future, therefore, we recommended that States begin to prepare now. “The authors of the report, one of the United States national renewable energy laboratory, Gavin ˙ Dr Heath on the southern weekend reporter.
Retired early, doesn’t care
Photovoltaic module recycling at home does not pay enough attention, because they are retired for some time.
In 2015, in support of PV Professional Committee of China renewable energy society, called “looking for the most beautiful old photovoltaic components” to expand activity in the Northwest, Southwest and so on. Activity party found power running nearly 30 years old components, although the process of rough, Rod rust, but this PV is still running.
Because the decline in power generation efficiency, the design life of the photovoltaic panels are generally set at 25, running for more than 25 years.
“After 2020, PV modules began to increase significantly the amount of waste. “The forecast from the Chinese Academy of Sciences Institute of Electrical Engineering Department of renewable energy power generation system, the” Twelve-Five “period, they took on the task as national 863 project” PV equipment recycling and harmless treatment technology research “. This is currently one of the few national studies.
PV maker Trina solar limited (hereinafter referred to as Trina) Xiong Zhen, Senior Manager of the Research Department also forecast 2020 for waste component issues in the beginning: “a small, perhaps only 5MW, less than 500 tons, and construction waste than is the ocean. “W (Watts) is the PV module power generation unit, a component can send a year of electricity, 5MW PV electricity from the merely 3,000 households a year in residential electricity consumption.
Early supply of China PV industry abroad, domestic mass install PV modules beginning in 2009, in order to absorb excess PV capacity, the State supports the implementation of the “Golden Sun demonstration project”, such as financial aid, technological support and market pull, accelerate the industrialization and development of domestic photovoltaic power generation.
863 project study on PV module recycling scale was predicted, in the case of power plant operation and maintenance good, 2034 and accumulated waste will reach nearly 60GW, power plant operation and maintenance under normal circumstances, 2034 estimated cumulative waste 70GW. Amount of electricity equivalent to 40 million homes.
Yingli Green energy holding company limited (hereinafter referred to as Yingli) further the result is: by the year 2030, China abandoned solar module produces 1.45 million tonnes of carbon steel, 1.1 million tons of glass, 540,000 tons of plastic, 260,000 tons of aluminum, 170,000 tons, 50,000 tons of copper and silicon and 550 tons of silver.
EU compulsory recycling
While domestic research and development into photovoltaic companies are few, but they have international standards.
PV recycling field of well-known agencies are located in Belgium, non-profit organization PVCYCLE. PV is the abbreviation of PV, CYCLE is recycled. The early 1990 ‘s, PV installation in Europe, began by the year 2007, in order to really distinguish it from conventional energy sources to become green power generation by waste management of “green” products, PVCYCLE came into being.

After the establishment of waste management platform, PVCYCLE EU PV module manufacturers, sales and installation of dealers and importers to provide collection and recycling services. 2010-2015, which recycled components have been the equivalent of more than 100 million cans of Coke bottles and liangqianduowanzhi glass.
When it was established, Member of PVCYCLE belong to the volunteer. In early 2014, the EU waste electrical and electronic equipment (WEEE) directive the integration of PV modules into one requiring scrap photovoltaic components and household appliances as a product, installation of current and historical to charge a mandatory recycling.
In fact, prior to the mandatory provisions of the WEEE, half of the members are Chinese companies. “And other members, China enterprises for sustainable waste management to demonstrate the same high level of commitment. “PVCYCLE, public relations director PIA ˙ Alina ˙, Langer said. Trina is also PVCYCLE – President of the Council of association the highest regulatory and guidance agencies.
According to the different national policies, members must pay dues and payment processing costs. “Depending on the requirements and market size, market share of large companies pay more. Overall, the collection and recycling of existing waste currently occupy only a small part of total costs, historical and future waste management component is the big head. “PIA said.
Gavin ˙ Dr Heath told the southern weekend reporter, Europe has the most mature supervision system of PV recycling, other parts of the world, there is no provision to force recycling of photovoltaic modules.
PVCYCLE has also affected the other countries and regions. JA Solar Holdings Co of Egypt refers to the components of the project recovery, because the developer is a European.
Domestic strategy of Chinese enterprises have also been infected. In 2009, the first to join Yingli is one of the earliest collection of the PVCYCLE research company. “In 2010, we’ve put together for PV rumors of problems, that question is the future of the recycling and harmless for large projects. “The Chief Technology Officer of Yingli Song Dengyuan said. Company’s first product is the 1998 ABA bright project for poverty alleviation of rural hydropower station in Sichuan, when used for more than 10 years.
National research on PV modules is not many, according to southern weekend reporter, may be only a few companies such as Yingli, Trina. “There are differences and treatment of electronic garbage, it’s research and development is just good, there can be four or five years of technical reserves. “Trina is responsible for research and development of Xiong Zhen said that their project has just started more than a year.
Other company’s domestic operations were also on the sidelines. JA Solar’s Marketing Director Fu Sengui introduction, JA’s current emphasis is also placed on the operation and maintenance of power plants.
In addition to the company, the Chinese research Academy of environmental sciences of the photovoltaic industry in the study of environmental impact and environmental management, as well as recycled content.
“Now scrapped components of little experiments to find obsolete components is difficult. In the field of recycling, the EU also has projects, technical courses and the research and development stage with China. “Central Academy project leader Liu Jingyang researcher said,” but not on the foreign research projects supported in China, we are participating in a declared major renewable energy projects, including recycling. “
Which recovery mode the most business prospects
PV modules including thin film crystalline silicon solar module and battery, running over 90% on the market belong to the former, recycle research has also focused on this.
To make PV modules to withstand wind and rain erosion, and component production have gone through rigorous testing, to 80 degrees Celsius temperature and lingxia40sheshidu low temperature cycle times. However, solid build was later recycled for early problem, “making the stronger the better, when they have to take apart the very troublesome. “Xiong Zhen said.

Our physical laws, many technologies such as pyrolysis alignment, is still in the laboratory stage of research and development. Late pre-production components can take into account recycling? Song Dengyuan recalled France had such a try, replaced with vacuum bonded component packaging technology in order to achieve “100% recovery”, but the selling point of current technology is not yet mature.
Than research and development more difficult, more difficult is the embodiment of commercial value.
A PV modules weighing more than 10 kg, after the open, glass and aluminum frame holds a 80% above the weight, the most valuable of the conductive silver paste only 6 grams. Yingli to calculated the economic benefits of crystalline silicon solar module recycling, component recycling has gross margins of about 5%, but this does not include shipping costs.
Photovoltaic power plant located in a remote, transportation is a big problem. Also PVCYCLE, recovery potential benefits have usually been in transportation costs and advance infrastructure investments to offset. “Because the recovery is still too small. “PIA explains,” so we find in the Europe-wide scope of partners, through economies of scale and competition, in the pursuit of the highest recovery rates while maintaining low prices. ”
EU recycling company and do not receive subsidies from the Government. How to improve efficiency, PIA is very optimistic: “the key is to increase the amount of waste in the next few years. “Efforts made by the Association, recovery rate has reached more than 90%.
Song Dengyuan is also very optimistic about the market. He believes that after a period of time, processing costs can cover the cost of the components, crystalline silicon solar module can cycle development. Yingli is expected at the national “Thirteen-Five” period to build a production line, gradually formed its own industrial and profitable. “State support recycling and harmless treatment technology in the future, regardless of whether the projects supported, and we will be on a production line. ”
Meanwhile, he also believes that PVCYCLE can refer to the EU model, through a membership system, allowing Member companies have the ability to demand but there is no ability to provide relevant services and benefits derived therefrom.
In commercial mode Shang, Peking University City and environment College Associate Professor Tong Xin of subject group to Shandong province for cases, proposed has three species stories: 1. scale economic stories: according to transport cost minimum of assumed, province established a concentrated cycle processing facilities; 2. market oriented stories: in population most intensive of two a most urban (Jinan and Qingdao) near established concentrated cycle processing facilities; 3. producers responsibility extends stories: by 6 home production enterprise using production location provides cycle processing facilities. Study results showed that the EPR has the best cost-benefit.
However, Tong Xin repeatedly stressed to journalists over the weekend in the South, more data are needed to support such studies.
In the area of subsidies, Fund subsidy is extended producer responsibility system of waste household appliances, home appliances manufacturing enterprises in production-related subsidies when product put into the Foundation, and then reviewed and issued by the relevant ministries of the State consumer electronics recycling business. If too much less, imbalance of the Fund, would have caused disruptions to waste recycling.
