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: What is the difference between photovoltaic products and solar energy?: At the same time, the solar photovoltaic power generation system, which is centralized, such as large northwest ground photovoltaic power system; one is distributed (divided by >6MW), such as building roof photovoltaic power generation system of industrial and commercial enterprises, residential roof photovoltaic power generation system.Solar photovoltaic effect, referred to as photovoltaic (PV), also known as the photovoltaic effect (Photovoltaic), refers to the uneven illumination of semiconductor or semiconductor and metal parts of the potential difference between the phenomenon of.Photovoltaic is defined as the direct conversion of ray energy. In the practical application, it usually refers to the conversion of solar energy to electric energy. Its implementation is mainly through the use of silicon and other semiconductor materials made of solar panels, the use of light to generate direct current, such as our daily lives can be seen everywhere in the solar cell.

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: How to make solar energy?: Do experiment. We put the foil affixed to the box, to reflect sunlight. Then put the metal bottle full of water in the box and secure it with a plastic foam.

Q: What are the forms of solar energy? My villa would like to design a comprehensive utilization of solar energy.: Solar hot water, solar photovoltaic power generation, various solar lamps

Q: What are the third generation solar cells: In 2004, Professor Green proposed the idea of developing the third generation solar cells. If we apply the semiconductor crystal film solar cell is called the first generation of solar cells, thin film solar cell is called the second generation solar cell, then the third generation solar cell solar cells the next generation is expected

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: 30MW solar thermal power plant total investment: The most expensive. Amorphous silicon solar cell conversion efficiency is the lowest, but the cheapest price, the most promising in the future will be used for general battery. Once a large area of the component photoelectric conversion efficiency of 10%, the price per watt power generation equipment down to $1 - $2, it is enough to compete with the current mode of power generation.

Q: New solar productsI would like to know the new type of solar energy production enterprises and the name, product performance and parameters.: Solar door lock lampThis is a new type of solar lock lamp solar panel for charging the battery, a LED lamp lighting, a full charge can continuously light 720 times, each time for 10 seconds, 10 seconds will be automatically extinguished, this time is enough for you to insert the key inserted the place.

Q: Are solar panels now in use?: Generally through the position, speed and torque in three ways to control the servo motor to achieve high-precision positioning of the transmission system, the transmission technology is the high-end products.

Q: Solar heating easy to use? Has anyone used it: If your house has a little heat preservation effect, the heat collector area is not enough. The first is fraud, very high! Followed by the heat collector is often no place to swing! Again, so many collectors, the heat generated in the summer there is also a problem
