Q:PV solar products market sales
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.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
Q:Solar energy items in daily life
Solar ice pad, solar panels, solar street lights, etc., are living in the solar green energy-saving products.
Q:Solar panels with single crystal silicon or good thanks
Single crystal or polycrystalline good?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!
Q:How much can the domestic high - temperature solar collector reach
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:What are the uses of solar energy?
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:Advantages and functions of solar energy
The technical field of solar energy utilization: only use solar energy there are three major technology areas, namely solar thermal conversion, conversion and optical shop in addition, photochemical conversion, and energy storage technology. The solar photoelectric conversion, mainly various types of solar panels and solar cell power supply system is to convert sunlight directly into electricity a device can the photoelectric efficiency of the solar cell is about 10-14% and its products are the main types of monocrystalline silicon, polycrystalline silicon and amorphous silicon. The domestic product (of a photoelectric device full cost) the price is about 60-80% yuan / Watt Peak. The scope of application of solar cell is very wide. Such as satellites, unmanned weather station, communication station, television relay station the sun, clock, electric poles, black lights, navigation lights, railway signal lights. Solar thermal conversion technology. Most of the products such as water heaters, boiling water heaters, dryers, refrigeration and heating, greenhouse and solar house, Solar range and high temperature furnace, seawater desalination device, water pump, thermal power generation device and solar energy medical appliance
Q:How to develop solar photovoltaic industry
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:The advantages and disadvantages of solar energy?Want to buy solar energy solar energy what is bad? Know about
I personally think that the use of solar energy is not very environmentally friendly, because the market is currently the main products of solar energy use monocrystalline silicon or polysilicon, thin film with very little. We all know that silicon is a heavy metal, pollute the environment and can not be removed, because the film component cheap but the conversion rate is low, can only be used in small products, such as computer, application of technology products such as lamps, although the silicon conversion rate is high but the price is expensive, so the application of products currently on the market to see the most use of polysilicon, 25 years after this type of product, service life expires, how to deal with??? Is a problem, so I still want to improve the conversion rate of thin film components.
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:Good solar polymer or monocrystalline
Strongly recommended products tested in the sun or cloudy days will not be worse than the single crystalPolycrystalline solar panels solar panels with batteries, our company is committed to the development of solar cell production, processing and sales as one of the most professional. Product solar panels: respectively, including epoxy encapsulated battery board (PET process components) monocrystalline silicon, polycrystalline silicon, as well as laminated toughened glass packaging large components and amorphous silicon solar panels. Can also be produced by a variety of shell materials or solar panels processing production cooperation. Products are widely used in small and medium-sized solar lighting, solar street lights, electric cars, mobile phones, toys, calculators, digital chargers, POLY crafts, can drive small motors, such as charging, power generation with. We can design according to your requirements. Respect every buyer to buy and put into operation
