US Solar scale ushered in a large rise in solar cell how to recycle

If the solar industry has left a trace of harmful waste, it cannot claim that it is clean energy. However, due to the lack of powerful photovoltaic recovery policies, the United States may be transported to millions of solar components and a large amount of poisonous substances in the next few years to the landfill. A new initiative, recycling photovoltaic solar seeks to solve this problem.

Pricing pricing and concerns about climate change, the US Solar Industry continues to maintain hot growth in 2020. Industry expansion slows, but does not suffer from the challenge of COVID-19 influenza and the hindrance of financial burden of import tariffs in Trump. The utility scale and residential solar market is booming, and the number of solar components is shocking.

The disadvantage is that the solar panel has a limited life, the recycling is difficult, high cost, and more and more solar panels retire. In terms of photovoltaic recovery projects and policies, the United States lags behind Europe and other regions, most of the solar panels that cannot be used are eventually filled. The EU and the US EU require photovoltaic component installer to be responsible for its electronic waste, and requires solar manufacturers to recycle, and Japan requires project developers and owners to be responsible for waste treatment, and request to retirement funds.

However, when it comes to the US federal government in the leadership of solar recycling and scrapped photovoltaic components, there is a vacuum. At present, the future of solar panel recycling in the hands of the United States. Most notably, under the leadership of Governor Jie Esli, Washington has a photovoltaic component management and recycling plan, requiring each photovoltaic component supplier to submit a recycling plan before July 2022.

However, comprehensive implementation may be delayed, waiting for the suggestion of stakeholders, including industrial and environmental groups. Only one US Solar Manufacturer has developed internal recycling capacity, which is currently only in handling the company's own thin film cadmium telluride board. The only full industry recycling initiative sponsored by the Solar Industry Association (SEIA), there are another five recycling partners in the United States, there are 12 locations, and there are 3 locations to be determined.

Solar Waste Regulations in Five Solar States in the United States: California - PV modules will be considered "universal waste", a lower classification of hazardous waste, can alleviate some transportation issues and costs. North Carolina - NCH329 regulations adopted in 2019 involves solar panel management Arizona - Ordinary Waste Management Florida - Ordinary Waste Management Texas - Normal Waste Management In most cases, cables and The aluminum frame is removed, and the remainder of the module is sent to the landfill. Solar component glass can be recycled - it accounts for most weights of solar components - but only a small part of component value.

Since the glass contains metal, the application of its second use is limited. These high-value materials, such as silicon, silver and copper, most currently in the United States have not been recycled. At the end of 2019, the circular photovoltaic solar energy company (RPVS) cooperated with European PVC Circular Company, launched a new project to solve these problems.

"I am also part of the problem.". I am responsible for deploying millions of solar panels.

"For me and my friends, in the early days of Schott, Sharp and Kyocera, our goal is 'cheap', we didn't take into account the end of life. The premise is that we sell is sustainable, no maintenance of green sustainable energy. "But as he pointed out, the solar panel is not manufactured for disassembly, the landfill is not green.

"Our (solar components) can be used for 30 years, so it is difficult to take out these materials. The status quo of American solar recycling is: We take the value of $ 1.25 to 1.

75, which is taken from a module, and the remaining is thrown into the landfill. Our RPV goal is to recover 94% to 95% of materials . At this point, the recycled material does not include the cost of recycling.

"Cost and revenue According to the state of Garvinheath, the national renewable energy laboratory, the cost of recycling a solar panel is 20 to 30 US dollars, and the cost of sending it to the landfill It is from 1 to 2 US dollars, which is why he said that research must focus on recycling solar silicon to improve battery board recovery. In November last year, Jigarshah, JieerateCapital, said that expanding the production person responsibility system (the manufacturer's manufacturer of manufacturers to deal with customers) may be helpful in recycling. "Manufacturers have been forced to cooperate, have recycling facilities in a joint approach, where they try to greatly reduce all of these costs, much higher than cost effectiveness.

This is achieved by policies. Shah said: "This is not achieved by people's choice.".

Van Dehofeg. He said that the Ministry of Energy should take the lead in working hard to solve the renewable energy circulation economy today, not ten years later. Photovoltaic battery board waste legislation can draw on early electronic waste legislation as a model, allowing manufacturers to pay for their waste, and establish a recycling fund similar to photovoltaic cycle, which provides for each solar panel Fee $ 0.

70. There are more innovative methods to process recycling, such as incorporating scrap processes and costs into the Power Convergence Agreement (PPA) and Operation and Maintenance Negotiation. Contractors, society and corporate governance investors also want to see the sustainability of the entire supply chain, and regulators may create market pricing mechanisms to achieve high-value recycling.

VanderhooW I hope to see a circular photovoltaic economy in the United States, including a "intelligent" reuse - recycling policy, based on reduced, reuse and recirculation 3R to create opportunities for business and economic development. According to a report of the International Energy (IEA) and International Renewable Energy (Irena), the economic benefits of the US Circular Economy may be around $ 135.3 million in 2020, reaching $ 1.

4 billion in 2030, to 2050. $ 10.1 billion.

Van Delhof said: "Economic multiplier will significantly increase these amounts. ". Re-supply and upgrade Although the recycling industry has realized (if there is no preparation), there is 25 years of history solar panels will be scrapped in the 1930s, but the RPVS CEO found another vaguely visible waste.

Solar battery board, system that has been upgraded and re-powered. Van Dehofeng pointed out that solar investors in the scale of public utilities are usually rewarded in the seventh year. In the 12th year, they re-supply power and get new investment tax credits.

The validity period of the PPA may be 25 years, but in the entire life cycle of the project, the panel may replace at least once. He claims to upgrade it before the end of the service life of solar panels, which will be more and more applicable to commercial solar roof and residential installation, because solar panels will also be damaged, and we are experiencing more More related questions related to weather. In general, SEIA said that the United States installed about 140,000 solar panels per day.

BLoombergnef further estimates that there will be approximately 26,000 tons of photovoltaic battery board this year. With the end of the useful life of the solar panels in the 1930s, this number will grow to millions of tons. In fact, North American solar power installed capacity exceeds 80 GW, to 2030, this number may grow to 400 GW.
