Q: What is the difference between photovoltaic products and solar energy?: Photovoltaic and solar energy is a concept.Photovoltaic (Solar Power): solar photovoltaic power generation system (Solar power system) for short, is a kind of semiconductor material using solar photovoltaic effect, will be directly converted to a new generation of electric power system with solar radiation, operate independently and grid connected in two ways.

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: Many foreign manor type home, need to decorate their homes solar lights.

Q: Product category and comparison of solar thermal utilization: The solar industry did a survey on the overall evaluation of the use of solar energy users, think very satisfied with only 3.5% basic satisfaction was 12.6%, average and unsatisfactory accounted for 35.2% and 48.7%; the user evaluation of the service, satisfied and satisfied for a total of 24%, and that no service dissatisfaction accounted for 76%.

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: Is it hot in summer and the water is hot in winter?: Wall type solar water heater can belong to the separated type solar hot water system, water tank placed in the balcony or exterior wall, the collector is placed at the south facade of building a balcony wall hanging type solar water heater with flat collector to absorb solar radiation into heat, heat to reach the water tank and the water heat exchanger, so that the temperature of the whole the water tank is increased gradually, let the user can enjoy free hot water from the sun.The successful use of plate heat exchanger technology in wall mounted solar products, not only improves the thermal efficiency of balcony wall products, and the successful implementation of the building safety products and life integration, so that the water heater installation expanded to all floors and is not limited to the roof, and greatly lifted the traditional solar water heater, frozen fried tube, easy Water Leakage, easy scaling problems.

Q: Solar energy application technology, there is no prospect: At present the solar energy situation is not optimistic, the Americas and Europe has Chinese solar "double reverse" and China internal and not good, can not be the own production of solar energy products consumed, resulting in pile up in excess of requirement. Therefore, many Chinese solar manufacturers have closed down.

Q: What are the references of the solar automatic tracking system: Tracking models were taken; gives the specific design ideas and methods of photoelectric tracking mode; to analyze and determine the sun trajectory calculation method, verified the feasibility of this method. According to the proposed tracking method, design a set of automatic tracking type independent solar photovoltaic power generation system. The system is a small photovoltaic power generation system based on automatic solar tracking, all-weather, high efficiency run independently, as much as possible the conversion of solar energy into electricity, to provide electricity load. The whole system is divided into automatic tracking system and two subsystems of solar photovoltaic power system, the photovoltaic power system is in the forest fire specific applications are analyzed and designed respectively. The design of hardware and software of the two subsystems. The hardware design includes the position of the sun and light intensity detection, calculation The software part of the system is designed, which is composed of computer control, data acquisition, external clock and photovoltaic power supply

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: Monocrystalline silicon market when the turnaround, to what extent: From the current technology development and application prospects, I believe that solar energy has the most opportunity to become the world's major alternative energy sources. 1, the whole world light is rich in resources, solar energy is inexhaustible, inexhaustible solar energy; 2, technology and talent in the world of IT technology talents emerge in an endless stream, transferred to the solar technology, solar photovoltaic industry and the IT industry is very similar to that of solar grade polysilicon and electronic grade polycrystalline silicon thin film technology is the extension of a. From the LCD technology, therefore, the solar photovoltaic technology upgrading is very fast, the power generation efficiency of photovoltaic cells is also more and more high, more and more low cost at the same time, smart grid and energy storage technology will further enhance the application of solar energy, the development of space is very large, and is not affected by resource constraints and resource prices, if a stable price support, can maintain long-term fixed income, therefore, the solar power industry as the development of financial products, insurance funds will be favored;

Q: Buy solar water heater mainly look at what?: Two, after-sales service is very important in accordance with the three products, the principle of service of seven points. After sales service in the choice of solar water heater also plays a big role. With the development of solar energy industry, more and more manufacturers, in these new manufacturers, many do not have plant equipment, parts to take OEM processing, business variables, quality is difficult to guarantee. Due to the small sales, when operating for a period of time after a loss and product quality problems, will run away. The products are sold without service. So in the choice of solar water heaters, the choice of large brand products is essential.
