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: 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: What are the disadvantages of traditional solar water heater: Because the water does not go glass tube, glass tube without fouling, the winter is not. The water heater can be pressurized, installed on the third floor, the first floor can also be used. If the water heater on the ground, the two floor, the third floor can also be used. So even if the existing architectural design is not perfect, the installation of solar energy, but also can be coordinated. At the same time, the electric water heater liner technology can also be used, so that the pressure bearing capacity of solar energy reached 6-10Kg.

Q: Solar energy has some disadvantagesDetailed description of the problem, to help the respondents give accurate answers: Second, the earth, no matter where there are solar energy, can be developed and used in the field, there is no transport problem, especially for the underdeveloped rural areas, islands and remote areas have more value. Third, solar energy is a clean energy, in the development and utilization, will not produce waste residue, waste water, waste gas, no noise, but will not affect the ecological balance.

Q: In the domestic high temperature solar energy collector can achieve how many degrees, the existing product and the technology form?: The tower system, Zhongxingpengyue pattern, looks very spectacular, is the image project of solar thermal power generation love. Its size is limited to 10~20 megawatt level, the use of special, very limited usefulness. The tower system operating temperature 600~1000 degrees Celsius, there are several foreign demonstration projects, the home also has heard, but I do not know the specific progress to that stage, both at home and abroad have not heard of commercial operation successfully.Dish type system, the operating temperature of 700~1400 degrees Celsius, stand-alone dozens of kilowatts, the system 5~25 mw. Due to the small machine, a large number of prototypes developed at home and abroad, but also did not hear of a successful large-scale commercial operation example. Due to the use of Stryn hot gas engine, its manufacturing technology requirements are high, greatly limiting its development.

Q: Is it hot in summer and the water is hot in winter?: Cloudy conditions, it is estimated that it will not be too hot, no care. If there is light in winter, then normal heating, you can use

Q: What about solar products?Solar panels solar panels: As long as the need to get electricity can. Solar lamp (lamp, landscape lamp, lawn lamp, flashlight, camping lights, lights and so on...), power generation system (Canada now many private power, is the placement of solar panels in the roof)...

Q: Home solar heating products can not mature?: Solar power generation, per square meter of power generation in 120W or so, the cost per square meter in 1500 yuan, the greater the area the lower the price2013 PV industry in Europe and the United States antitrust investigation, overcapacity led to the collapse of a large number of photovoltaic industry in Zhejiang, solar prices have fallen. This can be checked at any time onlineRecommended to buy solar water heater price per price in the 150-180 yuan, including in accordance with the material and other costs, buy a good look at whether there is a reliable after-sales

Q: Are solar panels now in use?: Its function is similar to the frequency converter acting on the common AC motor, which belongs to the servo system.

Q: Solar energy product development prospects?: 2 domestic solar water heater market development problems, intense competition. 2010 in the first half, the solar water heater industry ushered in the most severe market test, the number of manufacturers dropped from last year's more than 5 thousand to the current more than 2 thousand and 800. There are relevant data show that nearly 80% of the solar water heater companies have varying degrees of decline in sales, inventory increases and other issues, solar water heater industry's profits are getting lower and lower. In nearly 6000 domestic solar water heater business, really have the scale of production and R & D capabilities of enterprises less than 20, the rest for some local small workshops and brand-name enterprises. However, the quality of product inspection management, backward production technology, low price dumping, Jerry phenomenon in these small enterprises, resulting in solar water heater market order and chaos, there are many hidden dangers.
