2, 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 burning junction box of the most key of the whole system is the selection of diodes, depending on the type of component inside the cell is different, the corresponding diode is not the same.
3, 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. 4 laminated parts power structure (see below) the theme of the laminated structure (according to the process order) :
1, toughened glass Its role to protect the power subject (e.g., battery), selects the pervious to light is required: high light transmittance must (generally more than 91%).
2, 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, generating 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 efficiency should be very good, in the ordinary light can also generate electricity.
4, EVA: role as above, the main bonding encapsulation power main body and the back.
5, backplane, sealing, insulation, waterproof.
(generally use TPT, TPE, etc.) materials 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.

- Q: How to choose a good use of solar energy
- See brandAt present, there are more than 5 thousand brands of solar water heater industry, of which, a small family workshop type enterprises accounted for the majority of such enterprises weak competitiveness, the average life expectancy of enterprises, but only 1.5 years. Consumers choose products produced by such enterprises, often a few years later will become a three noes products, the interests of consumers can not be guaranteed. Therefore, consumers should choose in the country's high visibility of the big brands, big brands of solar water heaters not only reliable product quality, but also to provide consumers with long-term after-sales service protection.
- Q: Solar garden lamp product parameters
- Rainy days guarantee: can work continuously for more than 15 rainy days (regional / seasonal different) (can be made on request)Without the need for laying underground cables, without payment of lighting, key components of solar panels, solar garden lights the solar street lamp intelligent controller, DC maintenance free storage battery and a lighting lamp through the national development and Reform Commission, the world bank /GEF/ photovoltaic products certification. The utility model is mainly suitable for the lighting and lighting of the city road, the small square, the industrial park, the scenic spot, the park green belt, etc..
- Q: How to make solar energy?
- Many products using solar energy.1 boxes, 1 plastic bottles and cans; paint, glue, aluminum foil, plastic cloth; out of the plastic foam, metal bottle and transparent plastic paper, ready to do a solar water heater. You can do it.
- Q: What are the disadvantages of traditional solar water heater
- As a developing product, solar water heater is not perfect. People are skeptical about solar water heaters, solar water heaters can normal water supply, can bring convenience to life?
- 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.
- Power utilizationClear new energy in the future large-scale use of solar energy is used to generate electricity. There are many ways of using solar energy to generate electricity. Has been used mainly in the following two.1, the light - heat - electricity conversion. Heat generation by solar radiation. The utility model is characterized in that the heat energy absorbed by the solar collector is converted into the working substance steam, and then the steam driven turbine drives the generator to generate electricity. The first process is the conversion of light and heat, and the latter is the conversion of heat and electricity.2, optical electrical conversion. Its basic principle is to use the photovoltaic effect to convert solar radiation directly into electrical energy.
- Q: Solar energy products, that is, I would like to open a home solar products Daquan
- You come to buy a small brand, I guarantee the same brand and the water temperature. There ah, is to buy low in quality, the water temperature is much higher than the big brands, better quality, but the price is low. This is the answer to the water heater. Now I have to answer your question: I think a large and complete solar business success is unlikely, because you can do fine, because no sales manufacturers will hate you, you will not get a low price, so in the competition you will be in a passive position. There is a large investment in the business field, but this is taboo, because you invested huge output and small, out of proportion. As the election, do fine, do in this field, you are the boss. Others want to see your face. You can make a big profit this time.
- Q: How much does it cost to install solar energy in rural areas
- Two see insulation performance. The storage tank is a hot water storage tank, and its performance is mainly reflected in the insulation effect. Good insulation not only depends on the thickness of the insulation layer, but also insulation materials and processes. The use of automatic numerical control constant temperature and constant pressure quantitative foam, high temperature curing, thickening insulation layer of the water storage tank to ensure that the layer is more compact symmetry, thermal insulation performance is more durable.Three see bearing strength. Like the solar stent skeleton, of course not fragile. At present, there is a more streamlined tower support, which uses reinforced, super high base, to overcome the traditional thin rod bracket thin wind resistance of the problem, wind, rain, hail, corrosion resistance.
- Q: Solar panels with single crystal silicon or good thanks
- 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: Advantages and functions of solar energy
- Second: the earth, no matter where there is solar energy can be in situ development and utilization, there is no transport problem, especially for trafficunderdeveloped rural areas, islands and remote areas had more use value. Third: solar energy is a kind of clean energy. In the development and use, does not produce waste residue, waste water and gas, also there is no noise, but will not affect the ecological balance. Absolutely not cause pollution and pollution.
- Q: What are the current domestic solar energy products, which practical
- The advantages of solar water heaters and photovoltaic power generation are once and for all, slowly after many years of use can see the advantages of saving electricity bills, but the disadvantage is instability, a lot depends on the intensity of light.
