- Q: What is the difference between photovoltaic products and solar energy?
- Photovoltaic technology has many advantages such as: without any mechanical moving parts; in addition to sunshine, without any other fuel, can work in the sun and the oblique case; at the same time solar modules without maintenance, to minimize operating costs; and from site selection, is also very convenient, in the roof of the city open space, can be used. Since 1958, solar photovoltaic effect in the form of solar cells in the field of space satellites for the first time the application of energy. Today, the small automatic parking meter and rooftop solar panels, solar power center to the vast area, its application in the field of power generation has spread all over the world.Solar energy is a rapidly growing form of energy, the solar market has made great progress in the past ten years. According to information, according to the average annual installed capacity of solar power systems, the global solar market composite average annual growth rate of 47.4%, from 2003's MW growth of up to 2826 MW in 2007 to. It is estimated that by 2012, the annual installed capacity of solar energy system may be further increased to 9917 MW, while the entire solar energy industry sales may grow from $17 billion 200 million in 2007 to $39 billion 500 million in 2012. This growth is due in large part to the rapidly growing global market demand, rising electricity prices and various government incentives.
- 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: 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: Solar energy products, that is, I would like to open a home solar products Daquan
- I have two sets of solar home, one is Huang Ming, a sijimuge, later a temperature than the Emperor Ming of the seems to be a little higher, are also good, but home Taiwan Himin's high, I want to buy one, want to try another brand is not the same effect
- Q: Or must there be built - in battery? If yes, then use the mobile phone lithium battery can?
- . Cell phone lithium battery? Do you mean to put the mobile phone lithium battery on the solar panel? Do not Oh, can not be achieved, the direct use of solar panels charge mobile phone battery, then a little dangerous
- Q: Solar energy application technology, there is no prospect
- You can check the latest trends on the internet. According to experts, the development of the dual opposition to China's photovoltaic industry has a short-term impact, but a national leader also said: I hope that businesses can survive six months... The following is a detailed process of the EU against china. In February 28, 2013 the European Commission announced that the EU PV Glass Association complaint based on originating in the photovoltaic glass Chinese anti-dumping investigation, the photovoltaic glass soda lime glass plate, with iron content of less than 300ppm, the solar transmittance in the above 88% characteristics.
- Q: The advantages and disadvantages of solar energy?Want to buy solar energy solar energy what is bad? Know about
- 2, slow heating, temperature can not be stored, no storage function,Because now the market does not rely on solar energy storage battery, so no matter how good the sun, onlyTo provide the energy required for the day, the next day must be used on the rainy day electricity heatingWater heater fee
- Q: The best authoritative research report, even if their YYThank you for the answer to the first floor, but I found the 2000 water heater Research Report, although a bit long, but you can also use
- Consumer behavior analysisConsumers in the purchase of products, often have to consider the physiological needs, safety and health needs, psychological factors (environmental sustainability, energy saving, economic and other factors), at the time of purchase, often face 5 kinds of risk perception: one is the financial risk, that there may be a waste of money; the two is the function of risk, if function is not so good, or no brochures and advertising on the good; three is the physiological risk, looks a bit dangerous, afraid might get hurt; four is the social risk evaluation from fear surrounding friends not good; five is the psychological risk, because buy guilty, it would be irresponsible. For solar products, because the product and installation specification is not perfect, the implementation of the implementation of the lack of supervision, consumers lack of understanding of the core technology of solar energy, solar water heater does not have a clear understanding, in order to "Huiyanshizhu, consumers in the purchase, will be the main value of the brand, including corporate brand, product brand and service brand is the basis for the choice of consumers, because the brand is a commitment to consumers, its excellent quality, strong customer service service will guarantee the legitimate rights and interests of consumers; the value of quality products, to effectively meet the target market demand, such as the market part of the solar water heater can meet the demand of hot water in summer. But one winter has become idle goods, and even pipe cracking; value service, service satisfaction value, such as" Baidu service 100% satisfaction, service a little more satisfied with a little, through the service to reduce the risk of consumer awareness of the purchase.
- Q: Outdoor solar energy products, how can we do the process of IP65 level, the design of the water which should be noted that what? Beg enlighten heroes!
- Sub form to be simple, the need to seal the place where the seal can not add the province.Second, is the protection of components, internal structure should pay attention to water and diversion, it is best not to enter the water.
- Q: The steps of making solar technology stubs
- Step:1, the walnut tip toward the fire on the fire for a while, and then thrown into the cold water, walnut will split along the seam.2, the suture will break the walnut into two halves.
