Q: For example, solar flashlight, solar watches and other small solar products are what? Shenzhen where can be approved...: Solar energy power supply system for LED street lamp LED floodlightSolar lamp with LED outline lamp solar corridor lampSpecial lighting system for LED pulse cold light beauty lamp tent

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: 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 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: Major technical breakthrough:Multi junction solar cellNanostructured solar cellsPhotoelectrochemical solar cell

Q: Solar energy application technology, there is no prospect: I'm making solar energySimply put: solar energy is a new type of energy, the most important feature is pollution-free and inexhaustible. Therefore, under the condition of large amount of conventional energy consumption and environmental pollution, new energy has become a trend.

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: New solar productsI would like to know the new type of solar energy production enterprises and the name, product performance and parameters.: Solar automatic drip irrigation systemThe day before, Xinjiang production and Construction Corps three group introduced from Australia two solar automatic irrigation system, used for the first time in china.According to reports, this system is mainly composed of solar panels, automatic controller, water pump, filter, fertilizer tank, field network composed of several parts, it is the biggest characteristic of the photoelectric conversion of DC is generated by solar panel, direct drive pump automatically for the implementation of field crop irrigation, three solar panel configuration, total light area of 3.84 square meters, can produce a voltage of 132 volts, the power of 540W, the amount of water per hour is 2200 liters, 30 acres of drip irrigation can meet the needs; at the same time according to the optical conditions, the system can automatically open and close, the winter slack season, the system can also install conversion equipment, to meet the electricity needs of workers living.

Q: The advantages and disadvantages of solar energy?Want to buy solar energy solar energy what is bad? Know about: 3, placed the location of stress, angle, sunlight time, the surrounding environment is not easy to miscellaneous. Although the outside component is made of toughened glass, but also can not afford to toss the firecrackers. And aroundIf there is debris, easy to cause the "island effect" causes the component to burn oh.

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.
