Q:How to promote the use of solar energy in China

Overall, the use of solar energy is still very fast, or how the United States will be on China's solar energy products to ban it? As for the overall development of the domestic solar energy industry is good, but still need to do a lot of work. For example, how to improve the quality, efficiency, etc..

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:Solar panels with single crystal silicon or good thanks

Working principle: sunlight to the solar cell plate produced by the current through the inverter controller of the battery, the battery power through the inverter controller into DC or AC electric power supply (load), or through the grid connected inverter of direct energy input power grid. Solar photovoltaic system consists of solar cells, solar controller, battery (Group), such as the output power for AC 220V or 110V also need to configure the inverter. In the specific design of system engineering, the following factors should be considered:1, the actual total power (load) and the use of time, should be reserved for the normal operation of the system;2, the local effective sunshine time, the proportion of rainy weather;

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:Buy solar water heater mainly look at what?

Buy solar water heater mainly look at what?CDR | outside browse 976Recommended 2016-07-10 11:21:15 best answerBuy solar water heater, the four attention"First, the three components is the key to buy solar water heaters, analysis of production strength is very important. The strength of the enterprise is reflected in many places, and the key components are the most important. Three components include: vacuum tube, insulation layer and liner. The vacuum tube and the insulation layer determine the temperature rise and thermal insulation of the water heater, and the inner liner determines the life of the water heater, so these three parts are the core of the solar water heater. First, in accordance with national standards, the vacuum tube must be relatively high cost of high borosilicate 3.3 glass material, so as to ensure its light transmission and compression, anti-corrosion, impact resistance.

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:Good solar polymer or monocrystalline

Many of my friends would ask is good or good crystal crystal, we many people buy just as ordinary lighting and small system to watch TV, to tell the truth this is really no need to care about the single crystal or polycrystalline, regardless of the need is a power is enough, two is the price is good!The difference between polycrystalline and single crystal: single crystal plate is black, polycrystalline plate is blue or color.Disadvantages: the same power of the single crystal plate with polycrystalline plate, polycrystalline board area slightly larger than the area of single crystal board, the same as the 50W polycrystalline will be 1.1 times larger than the single crystalThe utility model has the advantages that the polycrystalline plate is a plurality of directions to receive light and has good directivity. The actual test, hypothesis with one hand to block the sun's rays to solar power on the surface of a shadow, so many crystal board power current decrease is not obvious, but the single plate power current is reduced obviously, this is the advantage of multi crystal plate.

Q:Solar energy application technology, there is no prospect

However, from a policy point of view, there is no industry like solar energy so much attention by the country. Compared with the traditional fossil energy, solar energy has obvious advantages. Therefore, the prospects are good.In a word, the future is bright, the road is tortuous!!

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

Q:The steps of making solar technology stubs

Material Science：Black plastic bag, rope.Making method:The black plastic bag filled with water after the bag tied in sunlight (see photo). After a while, the bag of water on the heat, can be used to wash your face, wash your feet.3 material: walnut, stick, rubber mud, small cloth.
