Why choose our solar panel is you ideal choose?

1. The important raw material, Solar cells, come from domestic public company and Taiwan famous company. Quality assurance: 25 years long life span, Industry leading power output warranty 10 years 100%, 20 years 95%, 25 years 85%. 

There are some company which select inferior solar cells that are processed from recycled silicon material from small workshop, so their solar panel service life maybe less than 5 years because inferior solar cell power reduce much more every year.

2. Our company has automated production line for solar panel. Good technology, good quality assurance. Strong production ability: 300 pieces 300w solar panels can be manufactured per day. Most of company weld solar cell with artificial manual work. Bad manufacturing technique is difficult to keep consistency of products.

Q:Solar panels single crystal and double crystal in the rain which is easy to use
From the cost of production, than the monocrystalline silicon solar cells to be cheaper, easy to manufacture materials, saving power consumption, the total cost of production is low, so get a lot of development. In addition, the polysilicon solar cell life than monocrystalline silicon solar cells shorter. From the performance and price ratio, monocrystalline silicon solar cells also slightly better.
Q:What is the working principle of solar panels?
The production of solar cells is mainly based on semiconductor materials, its working principle is the use of optoelectronic materials to absorb light energy after the photoelectricity in the conversion reaction, according to the different materials used, solar cells can be divided into:
Q:Can cold light make solar panels power
The drawback of solar thermal power generation is that the efficiency is low and the cost is high, At least 5 to 10 times more expensive than ordinary thermal power plants.
Q:What is the principle of solar panels to convert solar energy into electricity?
Solar cells are a pair of light response and can convert light energy into electrical devices. There are many kinds of materials to produce photovoltaic effects, such as: monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, selenium and other copper. Their power generation principle is basically the same, now the crystal as an example to describe the process of photovoltaic power generation.P-type crystalline silicon doped with phosphorus can be N-type silicon, the formation of P-N junction.
Q:What is the difference between solar panels and light panels?
The production of silicon requires that the stone be heated to become liquid, and the heating becomes gaseous crystals. During the need to burn a lot of fossil fuels and emissions of toxic gases silicon tetrachloride, this material has a corrosive effect on the skin. After pickling, pulling crystal, cut the side, finished a series of processes, more industrial chain. The cost of the finished product is too high. The energy consumption of making a solar cell requires solar cells to be equal in power generation for several years. The cost recovery period is very long.
Q:Composition and function of solar panels
The demand for polysilicon is mainly from semiconductors and solar cells. According to the different requirements of purity, divided into electronic and solar level.
Q:Polycrystalline solar panels are good or single crystal solar energy is good
. Since monocrystalline silicon is typically coated with tempered glass and waterproof resin, it is rugged and durable for up to 15 years and up to 25 years.
Q:What is the principle and structure of solar panels?
inverter: solar direct output are generally 12VDC, 24VDC, 48VDC. In order to provide power to 220VAC appliances, it is necessary to convert the DC power from the solar power system into AC power, so it is necessary to use DC-AC inverter.
Q:What is the principle of solar panels work?
Solar power generation There are two ways of solar power generation, one is the light - heat - electricity conversion, the other is the optical - electrical direct conversion.
Q:How many solar panels have ah?
However, crystalline silicon (monocrystalline silicon and polysilicon) in the weak light is basically no current generation, amorphous silicon weak light type (in low light energy is rarely). So a comprehensive view, it is appropriate to use monocrystalline silicon or polycrystalline silicon solar cell materials. Second, the choice of solar cells 1, we buy solar cells, the focus is on the power of solar cells, in general, the solar panel power is proportional to the area of ​​solar chips.
