- Q:New solar productsI would like to know the new type of solar energy production enterprises and the name, product performance and parameters.
- Solar automatic drip irrigation systemThe day before, Xinjiang production and Construction Corps three group introduced from Australia two solar automatic irrigation system, used for the first time in china.According to reports, this system is mainly composed of solar panels, automatic controller, water pump, filter, fertilizer tank, field network composed of several parts, it is the biggest characteristic of the photoelectric conversion of DC is generated by solar panel, direct drive pump automatically for the implementation of field crop irrigation, three solar panel configuration, total light area of 3.84 square meters, can produce a voltage of 132 volts, the power of 540W, the amount of water per hour is 2200 liters, 30 acres of drip irrigation can meet the needs; at the same time according to the optical conditions, the system can automatically open and close, the winter slack season, the system can also install conversion equipment, to meet the electricity needs of workers living.
- Q:PV solar products market sales
- The state has introduced the relevant subsidy policy, fairly good prospects.Solar power generating capacity per square meter is about 120W, the cost per square meter 1500 yuan in the area, the greater the lower the price of 2013 the PV industry has been an antitrust investigation in Europe, because of overcapacity in Zhejiang's large solar photovoltaic industry collapse, the price fell down. This can always online inspection recommended the purchase price of solar water heaters each priced at 150-180 yuan according to material, and other costs, the purchase is optimistic about the local power and reliable customer service of solar panels, the size of the group suggested bidding, mainly electric power and storage equipment is very expensive, the highest conversion rate in 17%-20% efficiency is very low now, as the plant photosynthesis national clean energy, photovoltaic power generation policy is more than 10kW can free grid, but the recovery price is very low, cumbersome.
- Q:How to promote the use of solar energy in China
- In this regard, the government should do a lot of work, industry associations have also made the relevant advance
- 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 hot water, solar photovoltaic power generation, various solar lamps
- Q:How to do a good job of solar water heater marketing?
- Three, safety: non pressurized solar water heater working principle. Gas water heaters, electric water heater is widely used in the existing safety problems, the province each year due to the accident, use water heater to cause death in 5 cases above, and with the increase of users, the number is rising, the use of solar energy does not exist poisoning and the hidden danger of electric shock, very safe, even if the solar water heater electric heating function, because the heating body away from the user, coupled with the use of time is only 1/10 of the electric water heater, so the possibility of harm has reached very little and negligible.
- 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: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: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:How to make solar energy?
- Do experiment. We put the foil affixed to the box, to reflect sunlight. Then put the metal bottle full of water in the box and secure it with a plastic foam.
