- Q:The steps of making solar technology stubs
- Material Science：Black plastic bag, rope.Making method:The black plastic bag filled with water after the bag tied in sunlight (see photo). After a while, the bag of water on the heat, can be used to wash your face, wash your feet.3 material: walnut, stick, rubber mud, small cloth.
- 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:What is the future of solar power
- Those who despise misleading consumer advertising! 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: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 are the functions of the new vehicle negative ion solar charging humidifier?
- A lot of cities have Brown's physical store, go to the store to buy.
- Q:How to make solar energy?
- Finally, cut a large hole in the box and put on a plastic wrap to absorb sunlight. A simple solar water heater is finished. I do the "solar water heater" to the teacher. The teacher said: "you have not put black metal bottles, so absorb sunlight more slowly, the water temperature is not easy to rise." So, we put the bottle of black metal.
- 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.
- Power utilizationClear new energy in the future large-scale use of solar energy is used to generate electricity. There are many ways of using solar energy to generate electricity. Has been used mainly in the following two.1, the light - heat - electricity conversion. Heat generation by solar radiation. The utility model is characterized in that the heat energy absorbed by the solar collector is converted into the working substance steam, and then the steam driven turbine drives the generator to generate electricity. The first process is the conversion of light and heat, and the latter is the conversion of heat and electricity.2, optical electrical conversion. Its basic principle is to use the photovoltaic effect to convert solar radiation directly into electrical energy.
- Q:Solar energy application technology, there is no prospect
- However, from a policy point of view, there is no industry like solar energy so much attention by the country. Compared with the traditional fossil energy, solar energy has obvious advantages. Therefore, the prospects are good.In a word, the future is bright, the road is tortuous!!
- Q:Is there any water in the solar energy to water?
- How much is the automatic water supply set level up to the number 2 can not need to fill 100 set automatic water temperature time to remove any fill
- Q:Outdoor solar energy products, how can we do the process of IP65 level, the design of the water which should be noted that what? Beg enlighten heroes!
- First, the packaging process,Design must consider the requirements of water, the structure can not be set up obstacles
