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: What are the disadvantages of traditional solar water heater: Because the water does not go glass tube, glass tube without fouling, the winter is not. The water heater can be pressurized, installed on the third floor, the first floor can also be used. If the water heater on the ground, the two floor, the third floor can also be used. So even if the existing architectural design is not perfect, the installation of solar energy, but also can be coordinated. At the same time, the electric water heater liner technology can also be used, so that the pressure bearing capacity of solar energy reached 6-10Kg.

Q: What is the future of solar power: Those who despise misleading consumer advertising! Solar power generating capacity per square meter is about 120W, the cost per square meter 1500 yuan in the area, the greater the lower the price of 2013 the PV industry has been an antitrust investigation in Europe, because of overcapacity in Zhejiang's large solar photovoltaic industry collapse, the price fell down. This can always online inspection recommended the purchase price of solar water heaters each priced at 150-180 yuan according to material, and other costs, the purchase is optimistic about the local power and reliable customer service of solar panels, the size of the group suggested bidding, mainly electric power and storage equipment is very expensive, the highest conversion rate in 17%-20% efficiency is very low now, as the plant photosynthesis national clean energy, photovoltaic power generation policy is more than 10kW can free grid, but the recovery price is very low, cumbersome.

Q: Or must there be built - in battery? If yes, then use the mobile phone lithium battery can?: . Cell phone lithium battery? Do you mean to put the mobile phone lithium battery on the solar panel? Do not Oh, can not be achieved, the direct use of solar panels charge mobile phone battery, then a little dangerous

Q: How much does it cost to install solar energy in rural areas: The question is more ambiguous, the installation of solar energy in rural areas there are many kinds of circumstances, is not used all year round, is not the villa type, is not the need for surfing the bathtub?Install solar energy in rural areas, the number of homes decided to install what kind of solar energy.

Q: Now there is no sun, cloudy days can use solar products?: In addition, if you are a household, engage in electric heating can be complementary to each other!

Q: 30MW solar thermal power plant total investment: The most expensive. Amorphous silicon solar cell conversion efficiency is the lowest, but the cheapest price, the most promising in the future will be used for general battery. Once a large area of the component photoelectric conversion efficiency of 10%, the price per watt power generation equipment down to $1 - $2, it is enough to compete with the current mode of power generation.

Q: What are the functions of the new vehicle negative ion solar charging humidifier?: Brown vehicle negative ion solar charging humidifier, in addition to negative ions and solar charging function, but also can be used as car fragrance, you can add essential oils.

Q: Solar panels with single crystal silicon or good thanks: The difference between polycrystalline and single crystal: single crystal plate is black, polycrystalline plate is blue or color.Disadvantages: the same power of the single crystal plate with polycrystalline plate, polycrystalline board area slightly larger than the area of single crystal board, the same as the 50W polycrystalline will be 1.1 times larger than the single crystalThe utility model has the advantages that the polycrystalline plate is a plurality of directions to receive light and has good directivity. The actual test, hypothesis with one hand to block the sun's rays to solar power on the surface of a shadow, so many crystal board power current decrease is not obvious, but the single plate power current is reduced obviously, this is the advantage of multi crystal plate.

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: Solar energy product development prospects?: 2012-2016 China solar cell market analysis and Investment Research Report1 solar water heater industry faces new integration. Industry concentration is not high, at present the country's top ten brands of solar companies together market share is less than the national market of 10%, companies want to get a larger market share is difficult. A line of enterprise and brand most high-end centralized development mode, to keep the solar intelligent and widely used will be closer, the solar water heater into the application of high-end, intelligent, integrated, brand enterprises lead the development direction of the industry's highest level and lead the industry, sales of high-end products less.
