1. Structure of TPt300 BackSheet for Solar Panel

TPt300 BackSheet for Solar Panel is a new generation of backsheet for solar panel, as an important component material of solar panel, new technology helps the backsheet have better performance and wider use. There is 4 layer`s structure of this series: Thicken PVDF film, binder pet polyester film, Fluorinated weather waterproof layer.

2. Main Features of TPt300 BackSheet for Solar Panel

With thicken PVDF film, we have better weathering, water blocking performance compare to PVF film(Tedlar)
More reliable inner film, easier for reworking.
Simple structure makes our BackSheet more reliable, more cost effectiveness.

5. FAQ

1. How to choose backsheet for solar panel?
It’s not easy question, but the first but most important thing is that the life period of the solar panel depends on the material quality of the backsheet.

2. If there is some scratches on the backsheet, how to deal with the solar panel?
Firstly, the scratch will destroy the waterproofness of the solar panel through the backsheet, which will finally have bad influence on the performance of the panel,; then the scratches on the backsheet should be regarded as defective and you should contact with the supplier or manufacturer to change it as soon as possible.

3. What is the color that backsheet should be?

Absolutely is white. As time goes by, the corrosion of the backsheet makes the white color into yellow. So make sure when you get the new solar panel the backsheet is in appropriate state.

Q: For example, solar flashlight, solar watches and other small solar products are what? Shenzhen where can be approved...: Solar energy power supply system for LED street lamp LED floodlightSolar lamp with LED outline lamp solar corridor lampSpecial lighting system for LED pulse cold light beauty lamp tent

Q: How to promote the use of solar energy in China: In this regard, the government should do a lot of work, industry associations have also made the relevant advance

Q: As a new energy solar energy has attracted more and more attention has been paid more and more practical application at home and abroad, I really want to know what are the solar energy application is very hope that we put forward their own views and even science fiction book that I want to do research on solar solar energy market in the military and political life etc.: Power utilizationClear new energy in the future large-scale use of solar energy is used to generate electricity. There are many ways of using solar energy to generate electricity. Has been used mainly in the following two.1, the light - heat - electricity conversion. Heat generation by solar radiation. The utility model is characterized in that the heat energy absorbed by the solar collector is converted into the working substance steam, and then the steam driven turbine drives the generator to generate electricity. The first process is the conversion of light and heat, and the latter is the conversion of heat and electricity.2, optical electrical conversion. Its basic principle is to use the photovoltaic effect to convert solar radiation directly into electrical energy.

Q: Is it hot in summer and the water is hot in winter?: Wall really electricity, as to what the effect depends on the brand. Hodge is certainly not good, the water temperature is low in winter. Now a lot of property to buy solar, generally for the hodge. As for the solar energy is better or you use absolute OK Himin - winter!!!

Q: How to make better use of solar energy: According to the history of the use of solar energy, solar energy has been used for more than 3000 years of history. The use of solar energy as a source of energy and power, only 300 years of history. The real solar energy as a much-needed supplementary energy in the near future, the basis of the future energy structure, it is a recent thing. Since 1970s, the rapid development of solar technology, solar energy utilization

Q: Solar derived products The role of solar panels is to convert solar energy into electrical energy, the output of DC stored in the battery: Through the analysis of the site we came to the conclusion that the whole system we use wireless bridge hybrid network Winncam wireless bridge 2.4 and 5.8, from point to point and point to multipoint network, set up three level wireless transmission network, which can smooth the audio and video in the network through the front-end equipment; we recommend using infrared network the camera, rear end accept can use a computer, but also can use the DVR DVR to use the decoding function. Finally, we can view and manage the entire system at the back end. The most extensive application of solar energy in the early stage is to heat water, and millions of solar water heaters are now available all over the world. The main components of the solar water heating system include three parts: the collector, the storage device and the circulating pipeline. In addition, there may be auxiliary energy device (such as electric heaters, etc.) used to supply without sunshine, in addition still may have forced circulation with water, with water level control device or control electric parts or temperature and received loads of pipeline etc.. According to the cycle of solar water heating system can be divided into two kinds:

Q: What are the references of the solar automatic tracking system: Tracking models were taken; gives the specific design ideas and methods of photoelectric tracking mode; to analyze and determine the sun trajectory calculation method, verified the feasibility of this method. According to the proposed tracking method, design a set of automatic tracking type independent solar photovoltaic power generation system. The system is a small photovoltaic power generation system based on automatic solar tracking, all-weather, high efficiency run independently, as much as possible the conversion of solar energy into electricity, to provide electricity load. The whole system is divided into automatic tracking system and two subsystems of solar photovoltaic power system, the photovoltaic power system is in the forest fire specific applications are analyzed and designed respectively. The design of hardware and software of the two subsystems. The hardware design includes the position of the sun and light intensity detection, calculation The software part of the system is designed, which is composed of computer control, data acquisition, external clock and photovoltaic power supply

Q: Are solar panels now in use?: Its function is similar to the frequency converter acting on the common AC motor, which belongs to the servo system.

Q: Monocrystalline silicon market when the turnaround, to what extent: From the current technology development and application prospects, I believe that solar energy has the most opportunity to become the world's major alternative energy sources. 1, the whole world light is rich in resources, solar energy is inexhaustible, inexhaustible solar energy; 2, technology and talent in the world of IT technology talents emerge in an endless stream, transferred to the solar technology, solar photovoltaic industry and the IT industry is very similar to that of solar grade polysilicon and electronic grade polycrystalline silicon thin film technology is the extension of a. From the LCD technology, therefore, the solar photovoltaic technology upgrading is very fast, the power generation efficiency of photovoltaic cells is also more and more high, more and more low cost at the same time, smart grid and energy storage technology will further enhance the application of solar energy, the development of space is very large, and is not affected by resource constraints and resource prices, if a stable price support, can maintain long-term fixed income, therefore, the solar power industry as the development of financial products, insurance funds will be favored;

Q: What are the current domestic solar energy products, which practical: Our use of solar energy can be roughly divided into two types of light and heat conversion and photoelectric conversion, in terms of household solar water heater and solar photovoltaic power generation.The solar water heater is widely used, manufacturers have Wuxi Suntech, linuoruite, Himin Solar energy, I think the emperor of the more, certainly not bad.
