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:Good solar polymer or monocrystalline: Working principle: the light of the sun to the solar battery plate current generated through the inverter controller for battery charging, battery power through the inverter controller into DC or AC electric power supply (load), or through the grid connected inverter of direct energy input power grid. Solar photovoltaic system consists of solar cells, solar controller, battery (Group), such as the output power for AC 220V or 110V also need to configure the inverter. In the specific design of system engineering, the following factors should be considered:

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:What are the functions of the new vehicle negative ion solar charging humidifier?: Quite a lot of functions, when the car humidifier, anion purification car air, solar charging, you can also add the essential oils when the car fragrance.

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:What are the disadvantages of traditional solar water heater: As a developing product, solar water heater is not perfect. People are skeptical about solar water heaters, solar water heaters can normal water supply, can bring convenience to life?

Q:PV solar products market sales: According to the State Administration of taxation policy released last year, from October 1, 2013 to December 2015 3l, according to the 3% levy rate calculation. In Takamatsu as an example, if a month sales of 30 thousand, that he should pay the tax is 30 thousand x 3% x 50%=450 yuan.Residents issued 1 kwh of electricity, the state subsidy of 0.42 yuan; the national standard for the purchase of electricity from the desulfurization of residents with endless self generating electricity, the price is $0.42 per degree. To install and use a set of distributed photovoltaic power generation system with an average of 1 kilowatts of installed cost about 10 thousand yuan, if the 8 kilowatt system daily generating capacity of 30 degrees, 5 degrees every household consumption (no more than a price of 0.52 yuan), about 8 years to recover the investment

Q:How to choose a good use of solar energy: Water capacity of water heaterAccording to the number of people, to determine the size of the solar water heater capacity, three of the family at least choose the volume of more than 100L, in general, the larger the size of the solar water heater tank, the better.Domestic solar water heaters to buy the first to determine the volume of solar water heaters. The general situation of the shower, according to the volume of 40-50L/ people to determine the volume of products to be purchased; the general bath needs about 35kg - 50kg hot water (45 degrees Celsius). Because solar non conventional energy in rainy days can produce hot water heater, so choose twice daily water consumption, the sunny hot water thermal storage to be used in rainy days. In the case of two consecutive days, you can choose to use dual-use photoelectric, to ensure all-weather, all year round hot water use

Q:The best authoritative research report, even if their YYThank you for the answer to the first floor, but I found the 2000 water heater Research Report, although a bit long, but you can also use: Competitor analysisThe solar water heater industry faces competition and substitute competition, has formed a professional brand, regional brand, brand and brand-name appliances co-exist in the market, the industry has fish, uneven in quality situation. With the competition and homogenization aggravating industry "reshuffle" is inevitable in the competition, need to break through the differences, creating a unique selling point, can focus on the product itself, can also be separated from the product itself, to create new demand from the consumer point of the competition range, consumers in the purchase of solar water heater in the purchase of solar energy is not, but convenient, safe, saving, healthy use of hot water. If you can surround the tube"

Q:Solar garden lamp product parameters: * storage battery: fully enclosed maintenance free lead-acid battery 15V20Ah - 80Ah* light source type: energy saving high power integrated LED, rare earth high efficiency energy saving lamp* protection level: IP65* use temperature: -30 degrees to 70 degrees, wind resistance is more than 150Km/h* lighting time: adjust as needed* pole height: according to need

Q:Are solar panels now in use?: Servo drive, also known as "servo controller" and "servo amplifier", is used to control the servo motor
