Q:Why can not the solar panel load directly?
Power supply must be a number of individual battery strings, connected in parallel and tightly packaged into components.
Q:Solar panels single crystal and double crystal in the rain which is easy to use
At present, monocrystalline silicon solar cell photoelectric conversion efficiency of about 15%, the highest reached 24%, which is all types of solar cells in the photoelectric conversion efficiency of the highest, but the production cost is so large that it can not be a large number of extensive And commonly used. 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 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:What is the main material for making solar panels?
You can also according to their own needs, according to the power to buy a good package of solar photovoltaic products.
Q:Can cold light make solar panels power
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:Single crystal solar panels and polycrystalline solar panels
monocrystalline silicon market share and a slight increase, and now the market to see the majority of single-crystal silicon cells. Monocrystalline silicon solar cell silicon crystal is very perfect, its optical, electrical and mechanical properties are very uniform, the color of the battery is mostly black or dark, especially for small pieces of small pieces of consumer products.
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:Can solar panels be connected directly to motor?
Power supply must be a number of individual battery strings, connected in parallel and tightly packaged into components.
Q:What is the principle and structure of solar panels?
Solar power generation system consists of solar cells, solar controllers, batteries (group) composition. If the output power is AC 220V or 110V, also need to configure the inverter. The role of each part is
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.
