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: Base salary is not high, the Commission is generally 1-2%, different places.

Q: Solar products must be in the sun: Energy (Solar), generally refers to the sun's radiant energy, passive use (photothermal conversion)

Q: Solar energy has some disadvantagesDetailed description of the problem, to help the respondents give accurate answers: Disadvantages of solar energy:The use of solar energy has its drawbacks:First, the current density is low, the sun is better, the ground floor area of 1 square meters of energy received only about 1 kilowatts. It is often necessary to set up a large number of lighting surface to meet the use requirements, so that the large area of equipment, materials, cost increases.Second, the greater the impact of the atmosphere, to bring a lot of difficulties.

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.: Uses as follows:Photothermal utilizationIts basic principle is to collect the solar radiation energy, and convert it into heat energy. At present, the most widely used solar collector, there are 4 types of flat plate collector, vacuum tube collector, ceramic solar collector and focus collector (trough, dish and tower). Usually according to the temperature and the use of the different, and the use of solar thermal light is divided into low temperature (<200 DEG C), the use of medium temperature (200 ~ 800 C) and high temperature utilization (>800 C). At low temperature using mainly solar water heater, solar dryer, solar distiller, solar heating (solar room), solar greenhouse, solar air conditioning system, the temperature is mainly using solar cookers, solar thermal power generation heat collecting device, mainly using high temperature high temperature solar furnace etc..

Q: What is the difference between the expensive solar energy and the cheap one?: Give you an example, for example, the same car, are four wheels, but Mercedes Benz and Xiali price is much worse, because Mercedes Benz safety good quality is high, can ensure the safety of life, your value

Q: 30MW solar thermal power plant total investment: At present, there are three kinds of solar cells, such as monocrystalline silicon, polycrystalline silicon and amorphous silicon. Monocrystalline silicon solar cell conversion efficiency of up to 20%, but the price

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: 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.

Q: Solar heating easy to use? Has anyone used it: Advice do not believe! Solar heating is just a concept in china. In theory, in northern China, walls, windows and doors insulation to do a very good case, a square meter of solar collectors up to 3 square meters of heating area. If your house is 90 square meters, according to this calculation, you need to have 30 square meters of solar collector area
