Q: For example, solar flashlight, solar watches and other small solar products are what? Shenzhen where can be approved...: Solar water lamp power supply, inverter solar watch packaging glass packaging film melted material monitoring system wiring box of solar wind cap regulator controller

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: How to promote the use of solar energy in China: Can you be more specific? Because I'm working on a project report, it's best to talk about two aspects of government and solar energy companies

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.: Solar cell[material requirements] ultraviolet radiation resistance, light transmittance does not fall. Tempered glass components can withstand the diameter of 25 mm of ice hockey at a speed of 23 m / sec.[properties of EVA film curing with the requirements after] the transmittance is more than 90%; the crosslinking degree is greater than 65-85%; peel strength (N/cm), glass / film is greater than 30; TPT/ film is more than 15; the temperature resistance, low temperature, high temperature of 85 DEG C to 40 DEG C; the back of the solar cell, aging resistance corrosion resistance, ultraviolet radiation, airtight etc..[use] solar power is widely used in solar lights, solar lamp, solar portable system, solar mobile power, solar products, communication power supply, solar lamps, solar buildings etc..

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: In 2004, Professor Green proposed the idea of developing the third generation solar cells. If we apply the semiconductor crystal film solar cell is called the first generation of solar cells, thin film solar cell is called the second generation solar cell, then the third generation solar cell solar cells the next generation is expected

Q: New solar productsI would like to know the new type of solar energy production enterprises and the name, product performance and parameters.: Solar door lock lampThis is a new type of solar lock lamp solar panel for charging the battery, a LED lamp lighting, a full charge can continuously light 720 times, each time for 10 seconds, 10 seconds will be automatically extinguished, this time is enough for you to insert the key inserted the place.

Q: Advantages and functions of solar energy: The technical field of solar energy utilization: only use solar energy there are three major technology areas, namely solar thermal conversion, conversion and optical shop in addition, photochemical conversion, and energy storage technology. The solar photoelectric conversion, mainly various types of solar panels and solar cell power supply system is to convert sunlight directly into electricity a device can the photoelectric efficiency of the solar cell is about 10-14% and its products are the main types of monocrystalline silicon, polycrystalline silicon and amorphous silicon. The domestic product (of a photoelectric device full cost) the price is about 60-80% yuan / Watt Peak. The scope of application of solar cell is very wide. Such as satellites, unmanned weather station, communication station, television relay station the sun, clock, electric poles, black lights, navigation lights, railway signal lights. Solar thermal conversion technology. Most of the products such as water heaters, boiling water heaters, dryers, refrigeration and heating, greenhouse and solar house, Solar range and high temperature furnace, seawater desalination device, water pump, thermal power generation device and solar energy medical appliance

Q: What are the current domestic solar energy products, which practical: Photovoltaic power generation system is mainly composed of solar cells, batteries, controller and inverter, the main part of solar cells. In the application of more public amenities such as solar street, home of the little, of course you can install the system of solar photovoltaic panels at home, 1W about ten dollars, plus the controller, you can see if you are able to supply applications at home how much money.
