PET Solar Panel means that the top layer of encapsulated material is PET film, which is a plastic film with a light transmittance of about 85%. Its surface can look shiny without any treatment, and if it is sprayed with a layer of frosted, it will look matte and a little rough to the touch.
PET solar panels are customized products with small sizes or low power output. The product structure is PET Film + EVA + Solar Cells + EVA or not + PCB. The solar cells are cut into small pieces by a laser machine, and the voltage and the electric current can be done as per the requirements, and then the single-layer transparent PET, EVA, solar cells, EVA, PCB backplanes are sequentially placed in a solar laminator for lamination. After about 20 minutes, take it out and then stick a soft and transparent protective film on the surface of the solar panel.
What are the advantages of PET solar panels? 1. It is suitable for the production of solar modules of various sizes and different voltages and currents to meet different application scenarios. 2. Quality standards are lower than glass laminated solar panel. 3. Short lamination time and high production efficiency. 4. Low cost.
What are the disadvantages of PET solar panels? 1. Long-term exposure to the outdoors will make the PET film hard, brittle, and discolored, reducing the light transmittance of the solar panel, and at the same time, it can’t well protect the PV cells inside to avoid oxidation and corrosion. If the surface is frosted, this layer of frosted will start to fall off and become very ugly after about 0.5 years. 2. Because the lamination time is not enough, the cross-linking degree of the entire solar panel will not meet the requirements. 3. It can’t resist the relatively large impact from the outside.
What are the applications of PET solar panels? Used for solar lawn lights, solar wall lights, solar handicrafts, solar toys, solar radios, solar flashlights, solar mobile phone chargers, solar small water pumps, solar home/office power supplies and portable mobile power systems and other products. It is not recommended to use PET solar panels that need to be placed outdoors for a long time and have a life expectancy of more than 2 years.

In the past two weeks (09.27-10.10), in response to power supply issues, the State Council of China convened an executive meeting to speed up the construction of large-scale photovoltaic bases and promote the implementation of energy-saving and carbon-reducing transformations in key areas. The arrangements made by the State Council will solve the problem of power cuts that have recently appeared, and ensure the basic lives of the people and the smooth operation of the economy. In these deployments, photovoltaics will play an important role. The following is the domestic and international photovoltaic industry information in the past two weeks.
State Council: Ensuring power supply and promoting the construction of large-scale photovoltaic bases
On October 8, the State Council of China held an executive meeting to further make arrangements for the supply of electricity and coal this winter and next spring to ensure the basic lives of the people and the smooth operation of the economy. The meeting pointed out that reforming and improving the market-oriented formation mechanism of coal and electricity prices, adjusting the fluctuation range of market transaction electricity prices from no more than 10% and 15%, respectively, to no more than 20% in principle. The industry can form prices through market transactions and is not subject to a 20% rise. Accelerate the construction of large-scale wind power and photovoltaic bases in the Gobi desert area, and accelerate the construction of emergency standby and peak shaving power sources. Resolutely curb the blind development of the “two highs” project. Improve the local energy consumption dual control mechanism, and promote that new renewable energy consumption will not be included in the total energy consumption within a certain period of time. Promote the implementation of energy-saving and carbon-reduction transformations in key areas.
Encourage rooftop distributed photovoltaic development
On September 30, ten ministries and commissions including the National Development and Reform Commission and the Ministry of Natural Resources issued the “Notice on Printing and Distributing Guidelines for the Standardized and Healthy Development of National Characteristic Towns.” The “Guidelines” pointed out that characteristic towns should, in accordance with the carbon peak and carbon neutral requirements, coordinate to promote high-quality economic development and high-level protection of the ecological environment. Promote clean, low-carbon, safe and efficient use of energy, guide non-fossil energy consumption and the development of distributed energy, develop rooftop distributed photovoltaics where conditions permit, promote clean heating and contract energy management. Promote low-carbon transformation in industry, construction, transportation and other fields, resolutely curb the blind development of “two highs” projects, vigorously develop green buildings, promote prefabricated buildings, energy-saving doors and windows, and green building materials, and promote green construction.
Tianjin promulgated regulations on promoting carbon peak and carbon neutrality to support the development of non-fossil energy such as solar energy
On September 27, the 29th meeting of the Standing Committee of the 17th Tianjin Municipal People’s Congress reviewed and approved the “Regulations on the Promotion of Carbon Peak Carbon Neutrality in Tianjin”, which will come into force on November 1, 2021. The “Regulations” put forward in the “Green Transition” section to support the development of non-fossil energy such as wind energy, solar energy, geothermal energy, and biomass energy, gradually expand non-fossil energy consumption, coordinate the promotion of hydrogen energy utilization, and promote low-carbon energy to replace high-carbon energy.
Lishui, Zhejiang: Accelerate the promotion of distributed photovoltaics and implement the “Photovoltaic +” project
On October 9, the Development and Reform Commission of Lishui City, Zhejiang Province issued a notice on publicly soliciting opinions on the “Implementation Opinions of the People’s Government of Lishui City on Accelerating the Development of Distributed Photovoltaics (Draft for Solicitation of Comments)”. The “Draft for Comments” requires that the large-scale development of distributed photovoltaic counties (cities, districts) is the starting point, and the “photovoltaic +” project will be fully implemented to promote the high-quality development of the green and low-carbon energy industry, and strive to build a green energy base in East China. Strive to add 1.5 million kilowatts of photovoltaic power to the city during the “14th Five-Year Plan” period, and implement policy support for financial rewards and subsidies.

Germany’s third-largest state requires solar energy to be installed on the roofs of all new houses
On October 6, the State Assembly of Baden-Württemberg in Germany passed a legal amendment requiring that from May 1 next year, all newly built houses in the state be installed with solar installations on the roof. From January 1, 2023, all existing buildings in the state will also be retrofitted with solar installations on the roof. This move aims to enable the state to achieve its goal of carbon neutrality by 2030. Baden-Württemberg is the third largest state in area and population in Germany, and the state capital Stuttgart is the headquarters of many well-known companies such as Daimler.
Kazakhstan: Double the share of renewable energy power generation by 2023
According to the official website of the Prime Minister of Kazakhstan, Ma Ming, the Prime Minister of Kazakhstan, hosted a video conference of the Council for the Improvement of the Investment Environment on October 9 to study the development of renewable energy and the transition to a “low-carbon economy”. In order to achieve the goal of achieving “carbon neutrality” by 2060 proposed by President Tokayev at the United Nations Climate Ambition Summit, the Kazakh government plans to double the share of renewable energy power generation by 2023 to 6%, compared with the previous one. The planned realization of this goal in 2025 is greatly advanced. In the next four years, the Kazakh government also plans to put into operation more than 60 new renewable energy projects, with a total installed capacity of 2,400 MW and a total investment of more than 2.5 billion US dollars.
