Q:What is the difference between the expensive solar energy and the cheap one?: Cohesive light film vacuum tube is used their thermal power generation technology, positive negative light, heat, warming faster, higher water temperature, which is unique in the world (Himin patent, ultra cold polar tube, Antarctic expedition team designated products, 40 degrees below zero still out of hot water, hot water is not broken; they are equipped with low winter) the temperature of the water level sensor, accurate induction, automatic operation of the whole system, you don't have to worry about is not water ah, can bathe ah; not only that, once the hot water machine what, their customer service staff will serve you within 48 hours. This is not high price but not expensive, is the value for money, or even value for money?

Q:Monocrystalline silicon market when the turnaround, to what extent: From the current technology development and application prospects, I believe that solar energy has the most opportunity to become the world's major alternative energy sources. 1, the whole world light is rich in resources, solar energy is inexhaustible, inexhaustible solar energy; 2, technology and talent in the world of IT technology talents emerge in an endless stream, transferred to the solar technology, solar photovoltaic industry and the IT industry is very similar to that of solar grade polysilicon and electronic grade polycrystalline silicon thin film technology is the extension of a. From the LCD technology, therefore, the solar photovoltaic technology upgrading is very fast, the power generation efficiency of photovoltaic cells is also more and more high, more and more low cost at the same time, smart grid and energy storage technology will further enhance the application of solar energy, the development of space is very large, and is not affected by resource constraints and resource prices, if a stable price support, can maintain long-term fixed income, therefore, the solar power industry as the development of financial products, insurance funds will be favored;

Q:What is the future of solar power: Residents issued 1 kwh of electricity, the state subsidy of 0.42 yuan; the national standard for the purchase of electricity from the desulfurization of residents with endless self generating electricity, the price is $0.42 per degree. To install and use a set of distributed photovoltaic power generation system with an average of 1 kilowatts of installed cost about 10 thousand yuan, if the 8 kilowatt system daily generating capacity of 30 degrees, 5 degrees every household consumption (no more than a price of 0.52 yuan), about 8 years to recover the investment. In accordance with the same calculation method, 10 kilowatts of distributed photovoltaic power generation device to recover the cost of 9-10 years. Family photovoltaic power plant to recover the cost of an average of between 8-10 years.

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:What are the forms of solar energy? My villa would like to design a comprehensive utilization of solar energy.: Solar heating, refrigeration, as well as solar panels with warm glass, heating room......

Q:Home solar heating products can not mature?: 1, the local climate: the solar water heater solar tube is not winter frost, but many people will find that in addition to solar tube other basically frozen broken in the actual use of the process, all the cold area, far distance roof is not recommended, the summer hail smashed zirendaomei. Before taking a bath before half a bucket of cold water, it is really a waste;2, installation conditions: the water pressure is not good, the floor is high, ready to install solar energy and electric hybrid proposal wash sleep. The related auxiliary equipment comprises a booster pump, a controller, will force you to spend a lot of innocent money, you are hard to feel the donkey3, economic price: the use of the price, the price of solar water heater in more than 3000, 1500 yuan, 2000 yuan while the gas water heater, solar electricity, but the experienced friends all know no electricity solar still can not be used, all can not talk about energy saving. On the use of the cost of natural gas pipeline gas prices in the province, followed by electricity tariffs, the overall cost of speaking, to buy more than 1500 yuan solar electricity tariff equivalent to 3000 degrees, enough for a few years of use.

Q:Is it hot in summer and the water is hot in winter?: Wall really electricity, as to what the effect depends on the brand. Hodge is certainly not good, the water temperature is low in winter. Now a lot of property to buy solar, generally for the hodge. As for the solar energy is better or you use absolute OK Himin - winter!!!

Q:Buy solar water heater mainly look at what?: Second, liner thickness. The quality of the liner determines the life of the water heater, if the water tank, the water heater will be scrapped. Major brand manufacturers use thickness of not less than 0.5mm of SUS304 food grade stainless steel liner. Argon arc welding is adopted to ensure the service life can reach more than 15 years. Other brands of water heaters in the liner between 0.2mm-0.4mm, the use of a period of time there will be water leakage problem. Therefore, consumers in the purchase of products must ask the thickness of the liner. At the same time, but also beware of patch water tank, the water tank liner is made up of a number of scrap steel belt, the entire inner bladder welding as many as dozens of times

Q:Solar products must be in the sun: Other light sources can be used to meet the needs of the product (e.g., solar watches can be recharged by other light sources)

Q:Good solar polymer or monocrystalline: Working principle: the light of the sun to the solar battery plate current generated through the inverter controller for battery charging, 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:
