- Q:Solar garden lamp product parameters
- * main body material: the lamp post is full steel structure, whole hot galvanizing / plastic spray treatment* solar modules: crystalline silicon 15-80WP (by load configuration)* operating voltage: DC 12V - 24V* controller: solar lamp controller, light control + time control
- Q:What are the disadvantages of traditional solar water heater
- We now have a factory in Wuxi, the production of solar water heaters, the core components - superconducting heat pipe, so that the product in place. Heat pipe is a vacuum glass tube inside, no leakage, no water absorption of solar heat, but the use of dark metal materials such as heat transfer, heat transfer efficiency is high temperature superconducting material.
- Q:Household solar energy productsThe product can be used at home, do not mention the solar energy, answer the water heater
- Solar thermal products are solar water heaters, as well as solar heating systems (usually in the North). Solar water heaters are used in several sets of hot plate, the more common is flat solar and vacuum tube solar two, the former used more in the south, the latter used more in the north.
- 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: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:Buy solar water heater mainly look at what?
- Buy solar water heater mainly look at what?CDR | outside browse 976Recommended 2016-07-10 11:21:15 best answerBuy solar water heater, the four attention"First, the three components is the key to buy solar water heaters, analysis of production strength is very important. The strength of the enterprise is reflected in many places, and the key components are the most important. Three components include: vacuum tube, insulation layer and liner. The vacuum tube and the insulation layer determine the temperature rise and thermal insulation of the water heater, and the inner liner determines the life of the water heater, so these three parts are the core of the solar water heater. First, in accordance with national standards, the vacuum tube must be relatively high cost of high borosilicate 3.3 glass material, so as to ensure its light transmission and compression, anti-corrosion, impact resistance.
- Q:How to make better use of solar energy
- The first stage (1900~1920 years) at this stage, is still the focus of solar power plant solar energy research in the world, but the spotlight by diversification, and began to use the flat plate collector and low boiling point device, gradually expanded, the maximum output power of 73.64kW, with the objective clear, cost is still high.
- Q:Good solar polymer or monocrystalline
- Many of my friends would ask is good or good crystal crystal, we many people buy just as ordinary lighting and small system to watch TV, to tell the truth this is really no need to care about the single crystal or polycrystalline, regardless of the need is a power is enough, two is the price is good!The difference between polycrystalline and single crystal: single crystal plate is black, polycrystalline plate is blue or color.Disadvantages: the same power of the single crystal plate with polycrystalline plate, polycrystalline board area slightly larger than the area of single crystal board, the same as the 50W polycrystalline will be 1.1 times larger than the single crystalThe utility model has the advantages that the polycrystalline plate is a plurality of directions to receive light and has good directivity. The actual test, hypothesis with one hand to block the sun's rays to solar power on the surface of a shadow, so many crystal board power current decrease is not obvious, but the single plate power current is reduced obviously, this is the advantage of multi crystal plate.
- 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:There are two years of foreign trade experience of the business to enter the basic salary and commission is what level is reasonable?Products are solar lights, solar chargers, solar power systems, solar power, LED induction lamps and other solar energy products
- Many foreign manor type home, need to decorate their homes solar lights.
