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: 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: Solar products must be in the sun: Solar energy products are generally inseparable from the sun, but there are also some of the solar radiation energy demand for smaller products

Q: How to do a good job of solar water heater marketing?: First, environmental protection: vacuum tube solar water heater purchase tips. According to the calculation, each household solar water heater during its 15 years of use, will reduce the coal to atmospheric carbon dioxide emissions of 26 tons, 136 tons of carbon monoxide, dust 1120 tons, 352 tons of sulfur dioxide, 908 tons of nitrogen and hydrogen compounds, this is not a small number of residents in our Province, in the subtropical zone. Suffering from the hot days of suffering, such as the province's residents are using solar water heaters can reduce the average temperature of 1 degrees, so the use of solar energy, make the sky bluer, mountains greener, the water clearer, gas cooler, is an effective measure of green environmental protection.

Q: Is there any water in the solar energy to water?: How much is the automatic water supply set level up to the number 2 can not need to fill 100 set automatic water temperature time to remove any fill

Q: What are the functions of the new vehicle negative ion solar charging humidifier?: A lot of cities have Brown's physical store, go to the store to buy.

Q: What about solar products?Solar panels solar panels: Solar photovoltaic products: photovoltaic modules and photovoltaic components, modules and components of rural production equipment, photovoltaic power generation system, photovoltaic equipment installation and accessories, grid connected photovoltaic system and photovoltaic transmission and distribution equipment; photovoltaic power / battery, charger, controller, inverter, water pump, solar power system equipment, solar energy conversion equipment, fuel cell, silicon solar cell, thin film solar cells, silicon single crystal silicon cell / raw materials, photovoltaic panels, glass cutting machine, testing equipment, various kinds of stove; wind solar diesel battery hybrid power systems, solar desalination system, solar photovoltaic electric vehicles, hydrogen production system, photovoltaic power generation system of computer application software; testing equipment of photovoltaic power generation system.

Q: Home solar heating products can not mature?: Solar panel power generation, then the proposed size of the proposed group, mainly the power substation and storage of electrical equipment is very expensive, the highest conversion rate in the 17%-20% efficiency is very low, not as good as plant photosynthesisNow the national clean energy, photovoltaic power generation policy is more than 10kW can be free of charge, but the price of electricity recovery is very low, cumbersome procedures.Buy solar water heaters, the first proposal to consider the local climate, installation conditions, economic prices and durability

Q: New solar productsI would like to know the new type of solar energy production enterprises and the name, product performance and parameters.: Solar automatic drip irrigation systemThe day before, Xinjiang production and Construction Corps three group introduced from Australia two solar automatic irrigation system, used for the first time in china.According to reports, this system is mainly composed of solar panels, automatic controller, water pump, filter, fertilizer tank, field network composed of several parts, it is the biggest characteristic of the photoelectric conversion of DC is generated by solar panel, direct drive pump automatically for the implementation of field crop irrigation, three solar panel configuration, total light area of 3.84 square meters, can produce a voltage of 132 volts, the power of 540W, the amount of water per hour is 2200 liters, 30 acres of drip irrigation can meet the needs; at the same time according to the optical conditions, the system can automatically open and close, the winter slack season, the system can also install conversion equipment, to meet the electricity needs of workers living.

Q: Solar panels with single crystal silicon or good thanks: Single crystal or polycrystalline good?Many of my friends would ask is good or good crystal crystal, we many people buy just as ordinary lighting and small system to watch TV, to tell the truth this is really no need to care about the single crystal or polycrystalline, regardless of the need is a power is enough, two is the price is good!
