- Q:As a new energy solar energy has attracted more and more attention has been paid more and more practical application at home and abroad, I really want to know what are the solar energy application is very hope that we put forward their own views and even science fiction book that I want to do research on solar solar energy market in the military and political life etc.
- 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: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:Household solar energy productsThe product can be used at home, do not mention the solar energy, answer the water heater
- Divided into two large photovoltaic and thermal.Photovoltaic power plant used in the battery board has two kinds of polysilicon and monocrystalline silicon, which is a little higher conversion rate. A solar photovoltaic system of solar power generation system, glass curtain wall, large on / off grid systems (e.g. Tibet Yangbajing engineering). In addition, there are solar street lights, scenery complementary street lights, solar lights, solar LED screen, solar backpack, etc.
- Q:How to choose a good use of solar energy
- See brandAt present, there are more than 5 thousand brands of solar water heater industry, of which, a small family workshop type enterprises accounted for the majority of such enterprises weak competitiveness, the average life expectancy of enterprises, but only 1.5 years. Consumers choose products produced by such enterprises, often a few years later will become a three noes products, the interests of consumers can not be guaranteed. Therefore, consumers should choose in the country's high visibility of the big brands, big brands of solar water heaters not only reliable product quality, but also to provide consumers with long-term after-sales service protection.
- 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:Solar energy product development prospects?
- 2012-2016 China solar cell market analysis and Investment Research Report1 solar water heater industry faces new integration. Industry concentration is not high, at present the country's top ten brands of solar companies together market share is less than the national market of 10%, companies want to get a larger market share is difficult. A line of enterprise and brand most high-end centralized development mode, to keep the solar intelligent and widely used will be closer, the solar water heater into the application of high-end, intelligent, integrated, brand enterprises lead the development direction of the industry's highest level and lead the industry, sales of high-end products less.
- Q:For example, solar flashlight, solar watches and other small solar products are what? Shenzhen where can be approved...
- Solar water heater solar range solar heatingSolar energy air conditioning hot water system solar panel solar energy power generation system encapsulation glue film solar battery lawn lamp garden lamp scenery complementary lamp signal lamp landscape lamp buried lamp
- 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:Solar energy application technology, there is no prospect
- At present the solar energy situation is not optimistic, the Americas and Europe has Chinese solar "double reverse" and China internal and not good, can not be the own production of solar energy products consumed, resulting in pile up in excess of requirement. Therefore, many Chinese solar manufacturers have closed down.
- Q:Solar heating easy to use? Has anyone used it
- Solar energy can be combined with heating. But it is still defined as "energy saving" more appropriate, rather than defined as "heating". The use of solar energy must be energy efficient. Suggest you can use gas stove heating, more money. If you want to save energy, then the gas stove and solar energy, solar bath, gas stove for heating and auxiliary heating as a solar energy.
