Q: How to promote the use of solar energy in China: Overall, the use of solar energy is still very fast, or how the United States will be on China's solar energy products to ban it? As for the overall development of the domestic solar energy industry is good, but still need to do a lot of work. For example, how to improve the quality, efficiency, etc..

Q: What are the third generation solar cells: What criteria are you referring to?There is not a recognized way of generational change;So there is no way to answer!

Q: Is there any water in the solar energy to water?: In the case of water inside the solar energy can also be irrigated 1,

Q: How much does it cost to install solar energy in rural areas: The question is more ambiguous, the installation of solar energy in rural areas there are many kinds of circumstances, is not used all year round, is not the villa type, is not the need for surfing the bathtub?Install solar energy in rural areas, the number of homes decided to install what kind of solar energy.

Q: Now there is no sun, cloudy days can use solar products?: The amount of radiation of solar water heater is the meaning of the sun. The sun did not reach that he cannot.

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: What about solar products?Solar panels solar panels: As long as the need to get electricity can. Solar lamp (lamp, landscape lamp, lawn lamp, flashlight, camping lights, lights and so on...), power generation system (Canada now many private power, is the placement of solar panels in the roof)...

Q: The advantages and disadvantages of solar energy?Want to buy solar energy solar energy what is bad? Know about: You mean the solar water heaterSimply say:Benefits: power saving, safety,Disadvantages: 1, temperature affected by the weather,Because solar water heaters rely mainly on the absorption of sunlight, the light energy into electricity for heating waterSo the intensity of the sun directly affects whether you need to use electricity heating

Q: Buy solar water heater mainly look at what?: Two, after-sales service is very important in accordance with the three products, the principle of service of seven points. After sales service in the choice of solar water heater also plays a big role. With the development of solar energy industry, more and more manufacturers, in these new manufacturers, many do not have plant equipment, parts to take OEM processing, business variables, quality is difficult to guarantee. Due to the small sales, when operating for a period of time after a loss and product quality problems, will run away. The products are sold without service. So in the choice of solar water heaters, the choice of large brand products is essential.

Q: Solar heating easy to use? Has anyone used it: Advice do not believe! Solar heating is just a concept in china. In theory, in northern China, walls, windows and doors insulation to do a very good case, a square meter of solar collectors up to 3 square meters of heating area. If your house is 90 square meters, according to this calculation, you need to have 30 square meters of solar collector area
