Q: In the domestic high temperature solar energy collector can achieve how many degrees, the existing product and the technology form?: Solar thermal power can be divided into three categoriesTrough system, tower system and dish system, they all belong to medium and high temperature system,Trough system is relatively popular in the other two categories, but also the most promising class. Operating temperature of 400~700 degrees Celsius, the scale is not limited to a few dozen megawatts, up to the level of Gigabit, there are some examples of successful commercial operation abroad. There are many prototypes in China, but there is no practical system.

Q: Solar electric vehicle charging device: Electric vehicle solar energy products are small in size, light in weight, easy to install and carry. Is a domestic initiative, has applied for national patent. Market potential is very large, very broad prospects.

Q: What is the future of solar power: 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. According to the State Administration of taxation policy released last year, from October 1, 2013 to December 2015 3l, according to the 3% levy rate calculation. In Takamatsu as an example, if a month sales of 30 thousand, that he should pay the tax is 30 thousand x 3% x 50%=450 yuan.

Q: How to do a good job of solar water heater marketing?: First, environmental protection: vacuum tube solar water heater purchase tips. According to the calculation, each household solar water heater during its 15 years of use, will reduce the coal to atmospheric carbon dioxide emissions of 26 tons, 136 tons of carbon monoxide, dust 1120 tons, 352 tons of sulfur dioxide, 908 tons of nitrogen and hydrogen compounds, this is not a small number of residents in our Province, in the subtropical zone. Suffering from the hot days of suffering, such as the province's residents are using solar water heaters can reduce the average temperature of 1 degrees, so the use of solar energy, make the sky bluer, mountains greener, the water clearer, gas cooler, is an effective measure of green environmental protection.

Q: How much does it cost to install solar energy in rural areas: With the continuous improvement of people's quality of life, every day at home to wash a hot bath has become a modern civilized lifestyle, economical and convenient solar water heater can meet the needs of people. However, in the face of dazzling array of solar products, how can you buy a satisfactory water heater? Himin to remind you that the purchase of solar energy to the four look".A look at the effect of condensing heat collection. The ability of condensing heat collection is an important sign to measure the performance of solar water heater, and is also an important factor affecting the heat gain of solar water heater. Vacuum tube solar water heater collector heart, it will make energy into heat energy, heat water in the water tank, so much the sameexternal conditions of vacuum tube to heat, directly affect the water temperature. At present, the market has two kinds of vacuum tube, a vacuum is manufactured by traditional gradient film tube, the other one is manufactured by international leading interference film patented technology, with the "three high vacuum high temperature resistance, anti cold, more efficient characteristics of the tube, the heat will be increased by 30%. Completely solve the traditional vacuum tube in the rainysky illumination is insufficient when the water temperature is not high, the winter temperature is too low when the solar water heater is not good problem.

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: 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: What are the references of the solar automatic tracking system: Using solar automatic tracking in the photovoltaic power generation system, can effectively improve the utilization of solar energy. Therefore, the research in this paper to improve the efficiency of photovoltaic power generation, has important significance to promote the popularization and application of photovoltaic power generation. This paper proposes a photoelectric tracking mode and solar tracking combined all-weather solar the automatic tracking method. Analyzed and sunny, cloudy and rainy weather condition three

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.
