Introduction:

PV ribbon is composed of Copper and coating alloys, and divided into Tabbing Ribbon and Bus bar ribbon.

Tabbing Ribbon: it is commonly connects the positive and negative sides of the cells in series.

Busbar Ribbon: it is concentrate the cell stringing into junction box and channels electrical current.

Q: There are two years of foreign trade experience of the business to enter the basic salary and commission is what level is reasonable?Products are solar lights, solar chargers, solar power systems, solar power, LED induction lamps and other solar energy products: Yes, for example, solar lights, developing and developed countries are in great demand

Q: Product category and comparison of solar thermal utilization: Why choose a new type of efficient flat plate solar water heater (device) system?In recent years, the use of solar thermal products in China has been rapid development. In the solar water heater manufacturing, use and market share, China has far ahead. However, due to the use of solar thermal products in domestic vacuum tube based, in full swing in the development of the industry, but also exposed a lot of worrying problems.

Q: How to promote the use of solar energy in China: Can you be more specific? Because I'm working on a project report, it's best to talk about two aspects of government and solar energy companies

Q: In the domestic high temperature solar energy collector can achieve how many degrees, the existing product and the technology form?: Above three types of high temperature system, although the operating temperature difference is not small, but the overall efficiency is not much difference, both in the 20~25%, and the temperature is high, the comprehensive efficiency is high, the business efficiency is not high.Low temperature solar thermal system, refers to less than 200~300 degrees Celsius, power is almost blank, because the theory of efficiency of solar thermal power generation system at low temperature is relatively low, but personally think that if the utility system developed a reasonable, the comprehensive efficiency and business efficiency is not low.

Q: As a new energy solar energy has attracted more and more attention has been paid more and more practical application at home and abroad, I really want to know what are the solar energy application is very hope that we put forward their own views and even science fiction book that I want to do research on solar solar energy market in the military and political life etc.: Solar cell[material requirements] ultraviolet radiation resistance, light transmittance does not fall. Tempered glass components can withstand the diameter of 25 mm of ice hockey at a speed of 23 m / sec.[properties of EVA film curing with the requirements after] the transmittance is more than 90%; the crosslinking degree is greater than 65-85%; peel strength (N/cm), glass / film is greater than 30; TPT/ film is more than 15; the temperature resistance, low temperature, high temperature of 85 DEG C to 40 DEG C; the back of the solar cell, aging resistance corrosion resistance, ultraviolet radiation, airtight etc..[use] solar power is widely used in solar lights, solar lamp, solar portable system, solar mobile power, solar products, communication power supply, solar lamps, solar buildings etc..

Q: Solar electric vehicle charging device: Electric vehicle solar energy products are small in size, light in weight, easy to install and carry. Is a domestic initiative, has applied for national patent. Market potential is very large, very broad prospects.

Q: What is the difference between the expensive solar energy and the cheap one?: Some solar energy is more expensive than other products! But is it worth it?! We do not have a word called a penny a point goods, product quality and price are proportional to

Q: Good solar polymer or monocrystalline: Spark solar energy products are also exported to many countries and regions such as Italy, Hongkong, Taiwan, the United States, Japan, Korea, Germany and other regions. After years of continuous development and improvement, not only to ensure good quality requirements, and won the domestic and foreign business partners to praise and affirmation. Stand on your point of view the factory must promise: fast delivery! Quality assurance! Price service is good. This season can undertake a large number of solar panels. This product can be customized for the price can also be agreed! Welcome to inquire or visit our company to discuss cooperation!

Q: New solar productsI would like to know the new type of solar energy production enterprises and the name, product performance and parameters.: As a result, the room window has become a new type of "solar window", "guide" the sun gathered on the four sides of the solar cell. The previous solar cell concentrator, is the use of large areas of moving mirror to track the sun. It is only in the roof and other open areas to set up the previous condenser. In contrast, solar windows do not take up space, easier installation and low cost.

Q: Solar energy product development prospects?: Summary: 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. Domestic solar water heater market development problems, intense competition. Local laws and regulations activate the project market, the development of the industry ushered in new growth, the rapid development of solar water heating system engineering market, government policy support. The pain of the industry - too frequent flow of talent. The flow of talent of the solar water heater industry is too frequent, among enterprises personnel frequent job hopping, which is harmful for the development of enterprises, but also bring the product homogeneity and marketing homogeneity consequences, market promotion means that the same product function and price of roughly the same situation.
