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:PV solar products market sales

The roof of photovoltaic power generation is less than 2 million monthly sales tax, in accordance with the provisions of the national taxation policy, power users need to provide sales invoices to the power supply enterprise, the buyer also need invoice offset the cost, and the personal power does not have the qualification of business owners, led by invoices complicated procedures. More than 20 thousand of the tax can not get the invoice, it increases the difficulty of the sales of power generation households, is not conducive to promotion. The State Administration of Taxation issued, will reduce the tax burden on household electricity."According to the State Administration of taxation documents, since July 1, 2014, the national Power Grid Corp to buy power products distributed photovoltaic power generation project, by the national Power Grid Corp invoices, monthly household electricity generating sales of more than 20 thousand products, owned by the national grid enterprises in accordance with the taxable amount of the 50% generation of vat. The monthly sales of less than 20 thousand yuan may be exempt from vat.

Q:Are solar panels now in use?

Generally through the position, speed and torque in three ways to control the servo motor to achieve high-precision positioning of the transmission system, the transmission technology is the high-end products.

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:Solar energy product development prospects?

3 local 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. Engineering market is mainly concentrated in the town, the construction of new rural residents in the housing construction, but also for the development of the engineering market provides a new opportunity. To November 2010, some enterprises in the hot water system engineering sales have accounted for the overall sales of 40%, compared with the previous total of only 5% to 15% of the proportion, this growth can be described by leaps and bounds. In the completion of the sale after the maximum sinking, hot water engineering market city building will become the brand of a hotly contested spot, always adhere to the rural areas as the focus of the strategy in the next few years, may turn to the rural market both strategic transformation development market as the leading city.

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: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: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:What are the current domestic solar energy products, which practical

The advantages of solar water heaters and photovoltaic power generation are once and for all, slowly after many years of use can see the advantages of saving electricity bills, but the disadvantage is instability, a lot depends on the intensity of light.
