Back contact solar battery components for good appearance, shading, high efficiency and less packaging
The advantages of small loss of attention, the Dutch national energy research center (ECN) study machine, etc
Structure is proposed based on an encapsulation of conductive foil lines connected, the use of conductive back substitution
The existing conventional polymer backboard, the basic structure of the products are: copper conductive back/EVA/of drilling hole
Conductive adhesive/cell/EVA/tempered glass, but the current conductive back is expensive and it is on the market
No mature products, and other conventional photovoltaic modules is: this kind of back contact components
Bus layer below the encapsulation EVA, close to the back surface, easy to produce water vapor intrusion and local
Discharge phenomenon, therefore, the structural reliability of special this component has yet to be further verified.
Back contact solar cells is aiming at the shortcomings of the existing technology and component technology
Provide a low cost, easy to implement and good reliability back contact solar arrays
A technology. Compared with the existing technology, the obvious advantages of zyprexa technology is that the back contact cells
Components using the conventional back and packaging materials on the market, on the one hand, reduces the cost of materials,
Simplify the production process, on the other hand also ensures that the component reliability and stability, have very much
Conducive to back contact photovoltaic modules of large-scale production needs.

In particular, back contact the solar cell component technology has the following advantages:
1. The main gate line, less decrease with silver
2. The shading area reduced, efficiency improved
3. No string of welding, series resistance is small, encapsulation losses small
4. Good heat dissipation, the same power can be more electricity
5. There is no welding, no stress, enhanced reliability
6. No welding, silicon wafer can be thinner
7. Use the conventional back and packaging materials on the market, reduce the material cost, simplify
- Q:PV solar products market sales
- 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.
- Q:How to open solar stores
- There is a solar dealer, in the local solar market, can be described as a coup. Use the bus as a propaganda tool, bus station, the first sentence is: "a certain store solar power station to remind you:" in the caption on the bus, he hit the store's telephone and communication; on the phone 114, the opening of the new building signs, banners, and even background cloth Online shopping, playing a certain solar energy store. In view of the store is more than the target customers, the dealer also sent a trick to go back and forth to its store expenses reimbursement, in this way, the customer into the store. With the help of external forces, a good manufacturer of this card. Dealers in the choice to join an industry, have to go through thousands of pick million, so that the industry has the impact of brand agents.
- Q:Monocrystalline silicon market when the turnaround, to what extent
- The world climate change, because solar energy is a one-time investment, the current data show that solar power business life cycle for 25 years, before 3 - 5 years for solar power plant manufacturing cost, the carbon dioxide produced far less than the size of the fossil power plant, therefore, the climate change and carbon dioxide emissions contribute to global; 4, the application prospect of solar energy is very extensive, both the roof power station, large-scale solar power plants, or used in human life will be very popular, the power system involves the possible and the sun can be combined.
- 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:The advantages and disadvantages of solar energy?Want to buy solar energy solar energy what is bad? Know about
- 3, placed the location of stress, angle, sunlight time, the surrounding environment is not easy to miscellaneous. Although the outside component is made of toughened glass, but also can not afford to toss the firecrackers. And aroundIf there is debris, easy to cause the "island effect" causes the component to burn oh.
- Q:How much does it cost to install solar energy in rural areas
- Two see insulation performance. The storage tank is a hot water storage tank, and its performance is mainly reflected in the insulation effect. Good insulation not only depends on the thickness of the insulation layer, but also insulation materials and processes. The use of automatic numerical control constant temperature and constant pressure quantitative foam, high temperature curing, thickening insulation layer of the water storage tank to ensure that the layer is more compact symmetry, thermal insulation performance is more durable.Three see bearing strength. Like the solar stent skeleton, of course not fragile. At present, there is a more streamlined tower support, which uses reinforced, super high base, to overcome the traditional thin rod bracket thin wind resistance of the problem, wind, rain, hail, corrosion resistance.
- Q:Solar energy products, that is, I would like to open a home solar products Daquan
- I have two sets of solar home, one is Huang Ming, a sijimuge, later a temperature than the Emperor Ming of the seems to be a little higher, are also good, but home Taiwan Himin's high, I want to buy one, want to try another brand is not the same effect

- 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
- On the direct use of solar energy in humans is still at the primary stage, mainly solar collectors, solar water heating systems, solar heating, solar power, solar wireless monitoring etc.. Along with the development of modern enterprise system in our country's popularization and deepening development of enterprise informatization construction unceasingly thorough, safety and prevention work for enterprises using digital video technology has been combined with the development of solar energy technology represent the general trend, the launch of the real Winncam zero wiring for wireless monitoring solution.
