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: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: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: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: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:Or must there be built - in battery? If yes, then use the mobile phone lithium battery can?
Solar panels because of light effects, such as shadow, the angle, so the output voltage is not stable, not stable in 5V, generally with a simultaneous mobile power output and input to the panel itself has a built-in battery, then of course better.
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:Solar products must be in the sun
Energy (Solar), generally refers to the sun's radiant energy, passive use (photothermal conversion)
Q:Solar derived products The role of solar panels is to convert solar energy into electrical energy, the output of DC stored in the battery
1 natural circulation:This type of storage tank is placed above the collector. Water heating collector in solar radiation temperature rise, causing the collector and tank water temperature and have a different density difference, thus causing buoyancy, this is like a hot siphon, the water flow in the water storage tank and collector. Because of the density difference, the water flow rate is proportional to the solar energy absorbed by the collector. This kind of type is widely used because it does not need the circulating water and the maintenance is very simple.2 forced circulation:The water in the hot water system makes the water circulate between the collector and the water storage tank. When the water temperature at the top of the collector is higher than the water temperature of the bottom of the water storage tank, the control device can start the water to make the water flow. A check valve is arranged at the entrance of the water to prevent the nighttime water from being driven by the collector to cause heat loss. The flow rate of this type of hot water system can be known (as a result of the flow from the water), easy to predict performance, can also be calculated in a number of hours of heating water. As in the same design condition, the natural circulation has can gain higher water temperature strengths, but because it must use water, the water power and maintenance (such as Water Leakage etc.) and the control device of dynamic stop, damage easily water problems. Therefore, in addition to large hot water system or the need for a higher water temperature, the forced circulation, the general use of natural circulation water heater. Solar power system consists of solar cells, solar controller, battery (group). Such as output power for AC 220V or
