Product Description:

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 third generation solar cells
Major technical breakthrough:Multi junction solar cellNanostructured solar cellsPhotoelectrochemical solar cell
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 are the forms of solar energy products
Solar heating, refrigeration, as well as solar panels with warm glass, heating room......
Q:Buy solar water heater mainly look at what?
Second, liner thickness. The quality of the liner determines the life of the water heater, if the water tank, the water heater will be scrapped. Major brand manufacturers use thickness of not less than 0.5mm of SUS304 food grade stainless steel liner. Argon arc welding is adopted to ensure the service life can reach more than 15 years. Other brands of water heaters in the liner between 0.2mm-0.4mm, the use of a period of time there will be water leakage problem. Therefore, consumers in the purchase of products must ask the thickness of the liner. At the same time, but also beware of patch water tank, the water tank liner is made up of a number of scrap steel belt, the entire inner bladder welding as many as dozens of times
Q:How to make solar energy?
Many products using solar energy.1 boxes, 1 plastic bottles and cans; paint, glue, aluminum foil, plastic cloth; out of the plastic foam, metal bottle and transparent plastic paper, ready to do a solar water heater. You can do it.
Q:30MW solar thermal power plant total investment
0MW total investment in solar thermal power plants:Solar thermal power generation units at home and abroad to invest 1.5~3 yuan /kW range, so 30MW power plant is currently estimated to invest 5-9 billion yuan RMB.
Q:Advantages and functions of solar energy
The advantages of solar energy: solar energy as a new energy, compared with conventional energy it has three major characteristics: first, it is the most abundant energy source. It is estimated that in the past 1 billion 100 million years, the sun itself consumes energy in the future 2%. is sufficient to supply earth, using billions of years it is inexhaustible, inexhaustible.
Q:Solar energy items in daily life
Solar water heater, charging treasure, rotating wheel, battery board Solar cell / solar engine
Q:Solar energy product development prospects?
2 domestic solar water heater market development problems, intense competition. 2010 in the first half, the solar water heater industry ushered in the most severe market test, the number of manufacturers dropped from last year's more than 5 thousand to the current more than 2 thousand and 800. There are relevant data show that nearly 80% of the solar water heater companies have varying degrees of decline in sales, inventory increases and other issues, solar water heater industry's profits are getting lower and lower. In nearly 6000 domestic solar water heater business, really have the scale of production and R & D capabilities of enterprises less than 20, the rest for some local small workshops and brand-name enterprises. However, the quality of product inspection management, backward production technology, low price dumping, Jerry phenomenon in these small enterprises, resulting in solar water heater market order and chaos, there are many hidden dangers.
Q:What is the future of solar power
The roof of photovoltaic power generation is less than 2 million monthly sales tax, in accordance with the provisions of the national taxation policy, power users need to provide sales invoices to the power supply enterprise, the buyer also need invoice offset the cost, and the personal power does not have the qualification of business owners, led by invoices complicated procedures. More than 20 thousand of the tax can not get the invoice, it increases the difficulty of the sales of power generation households, is not conducive to promotion. The State Administration of Taxation issued, will reduce the tax burden on household electricity." According to the State Administration of taxation documents, since July 1, 2014, the national Power Grid Corp to buy power products distributed photovoltaic power generation project, by the national Power Grid Corp invoices, monthly household electricity generating sales of more than 20 thousand products, owned by the national grid enterprises in accordance with the taxable amount of the 50% generation of vat. The monthly sales of less than 20 thousand yuan may be exempt from vat. 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.
