Q: How to choose a good use of solar energy: Water capacity of water heaterAccording to the number of people, to determine the size of the solar water heater capacity, three of the family at least choose the volume of more than 100L, in general, the larger the size of the solar water heater tank, the better.Domestic solar water heaters to buy the first to determine the volume of solar water heaters. The general situation of the shower, according to the volume of 40-50L/ people to determine the volume of products to be purchased; the general bath needs about 35kg - 50kg hot water (45 degrees Celsius). Because solar non conventional energy in rainy days can produce hot water heater, so choose twice daily water consumption, the sunny hot water thermal storage to be used in rainy days. In the case of two consecutive days, you can choose to use dual-use photoelectric, to ensure all-weather, all year round hot water use

Q: What are the forms of solar energy? My villa would like to design a comprehensive utilization of solar energy.: Solar energy can solve hot water, power generation, heating, swimming pool, breeding, lighting, cooking, and many other problems, you really want to design a comprehensive utilization of solar energy can find me

Q: Solar energy has some disadvantagesDetailed description of the problem, to help the respondents give accurate answers: Disadvantages of solar energy:The use of solar energy has its drawbacks:First, the current density is low, the sun is better, the ground floor area of 1 square meters of energy received only about 1 kilowatts. It is often necessary to set up a large number of lighting surface to meet the use requirements, so that the large area of equipment, materials, cost increases.Second, the greater the impact of the atmosphere, to bring a lot of difficulties.

Q: Solar energy products, that is, I would like to open a home solar products Daquan: Photoelectric, two large blocks of light and heat, I think it will be a complete. But a lot of financial strength to do it

Q: What are the third generation solar cells: The physical connotation contained in it is: should keep the advantages of the second generation thin film solar cell with low cost, and is much higher than the Shockley-Queisser limit (32.8%) high efficiency, stable and reliable performance and the battery and battery rich material sources. In other words, the so-called third generation solar cell is a kind of high efficiency, low cost, long life, non-toxic and high stability of the near ideal photovoltaic solar cells."

Q: Is there any water in the solar energy to water?: Yes, but it's best not to add water during the day

Q: Buy solar water heater mainly look at what?: Second, liner thickness. The quality of the liner determines the life of the water heater, if the water tank, the water heater will be scrapped. Major brand manufacturers use thickness of not less than 0.5mm of SUS304 food grade stainless steel liner. Argon arc welding is adopted to ensure the service life can reach more than 15 years. Other brands of water heaters in the liner between 0.2mm-0.4mm, the use of a period of time there will be water leakage problem. Therefore, consumers in the purchase of products must ask the thickness of the liner. At the same time, but also beware of patch water tank, the water tank liner is made up of a number of scrap steel belt, the entire inner bladder welding as many as dozens of times

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

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!: Third, the less the number of parts as possibleFourth, when the whole is a way to allow glue

Q: The steps of making solar technology stubs: Making method:1 at the end of the rubber to dig a shallow small round hole 2 to remove the brush pen head, clean and dry.3 cut the tip of the brush head into a small brush4 put the brush head into the small hole in the rubber, glue (complete)2 small production: solar hot water bag
