2 aluminium alloy layer pressure, seal, support role
Three junction box to protect the whole power generation system, have the effect of current transit, if the component junction box automatically disconnect short circuit battery series, to prevent burn out the whole system. Junction box is most critical in the selection of diodes, depending on the type of component inside the cell is different, the corresponding diode is not the same.
4 silicone sealing function, which is used to seal components and aluminum alloy frame, the component and junction box at the junction of some companies use double-sided tape, foam instead of silicone, now domestic commonly used silica gel, the craft is simple, convenient, easy to operate, and low cost.
Laminated structure (according to the process order) :
1 toughened glass: the role to protect the power subject (e.g., battery), pervious to light the selection is required, high light transmittance must (generally more than 91%); Super white steel processing.
EVA: fixed toughened glass used for bonding and power main body (e.g., battery), the merits of the transparent EVA material directly affect the life of the components, exposed to the air in the EVA aging yellow, thus affect the light transmittance of the component, thus affect the quality of the component's power in addition to the quality of EVA itself, component manufacturer of laminating process influence is very big, such as below-standard EVA glue viscosity, EVA and toughened glass, the back adhesive strength is not enough, will cause EVA early ageing, affecting the service life of components.
3 power main body: the main role is power generation, power generation main market is the mainstream in the crystalline silicon solar cells, thin film solar cells, both have their own advantages and disadvantages of crystalline silicon solar cells, equipment cost is relatively low, but consumption and cell costs are high, but the photoelectric conversion efficiency is high, in the outdoor sun power is more suitable for thin film solar cells, relatively high equipment cost, but low consumption and cost of batteries, but the photoelectric conversion efficiency relative to crystalline silicon cells in half, but weak light effect is very good, in the ordinary light can also generate electricity.
4: lagging effect, sealing, insulation, waterproof material (usually use TPT, TPE, etc.) must be resistant to ageing, component manufacturers warranty for 25 years now, toughened glass, aluminum alloy is generally no problem, the key is in the back and the silicone can meet the requirements. Editing this section of the basic requirements 1, able to provide enough mechanical strength, make the solar battery components can stand in the process of transportation, installation and use of shock, vibration, stress, able to withstand hail click force; 2, good sealing, windproof, waterproof, isolated from corrosion of atmospheric conditions for solar cell; 3, has a good electrical insulating performance; 4, anti-ultraviolet radiation ability; 5, according to the request of different working voltage and the output power design, can provide many kinds of connection mode, can satisfy the demands of different voltage, current and power output;
5: caused by solar cells in series and parallel combination efficiency loss of small;
Reliable connection of 6: solar cells;
7: long working life, require the solar cell components under natural conditions to be able to use more than 20 years;
8: to meet the conditions, the packaging cost as low as possible.
- 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 is the difference between the expensive solar energy and the cheap one?
- Give you an example, for example, the same car, are four wheels, but Mercedes Benz and Xiali price is much worse, because Mercedes Benz safety good quality is high, can ensure the safety of life, your value
- Q:What are the disadvantages of traditional solar water heater
- Lift people on science and technology, doubt, this contribution should be attributed to the Tsinghua sunshine and Emperor Ming in the past few years, their initial promotion products contributed to improvements in the manufacturing process, the product has also made a contribution. Make people know the solar water heater.
- Q:Monocrystalline silicon market when the turnaround, to what extent
- From the current technology development and application prospects, I believe that solar energy has the most opportunity to become the world's major alternative energy sources. 1, the whole world light is rich in resources, solar energy is inexhaustible, inexhaustible solar energy; 2, technology and talent in the world of IT technology talents emerge in an endless stream, transferred to the solar technology, solar photovoltaic industry and the IT industry is very similar to that of solar grade polysilicon and electronic grade polycrystalline silicon thin film technology is the extension of a. From the LCD technology, therefore, the solar photovoltaic technology upgrading is very fast, the power generation efficiency of photovoltaic cells is also more and more high, more and more low cost at the same time, smart grid and energy storage technology will further enhance the application of solar energy, the development of space is very large, and is not affected by resource constraints and resource prices, if a stable price support, can maintain long-term fixed income, therefore, the solar power industry as the development of financial products, insurance funds will be favored;
- 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:How much does it cost to install solar energy in rural areas
- Four look at the brand, service. The solar water heater host outdoors year-round by professionals need to withstand exposed to wind and rain, maintenance, maintenance. At present, there are 4000 domestic solar water heater factory, as the country has not yet unified solar water heater testing standards, some of the quality of the product does not pass, installation services are not in place, to bring trouble to users. Buy solar energy is not only a product, but more importantly, service". Therefore, we should choose the strength of the brand name of professional manufacturers of products, such manufacturers to install service personnel are generally through professional and technical training, service and thoughtful, so that you do not worry, get the best protection.
- 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:How to make better use of solar energy
- The history of modern solar energy can be calculated from the 1615 French engineer Solomon de Cox in the world invented the first solar powered engine. The invention relates to a machine for pumping water by using solar energy to heat air to make it work. Between 1615 and 1900, the world has developed a number of solar power devices and other solar devices. Almost all of these power plants by condensing method to collect the sunlight, engine power is not the working fluid is mainly water vapor, the price is expensive, little practical value, for the majority of fans of solar energy manufacturing. Twentieth Century 100 years, the history of the development of solar energy technology can be divided into seven stages.
- Q:How to make solar energy?
- Do experiment. We put the foil affixed to the box, to reflect sunlight. Then put the metal bottle full of water in the box and secure it with a plastic foam.
- Q:The steps of making solar technology stubs
- Step:1, the walnut tip toward the fire on the fire for a while, and then thrown into the cold water, walnut will split along the seam.2, the suture will break the walnut into two halves.
