Solar panel Solarpanel Classification: Crystalline silicon Battery Board: polycrystalline solar cells, monocrystalline silicon solar cells. Amorphous silicon panels: thin film solar cells, organic solar cells. Chemical Dye Battery Board: Dye-sensitized solar cells. [edit this paragraph] solar power system solar power system by solar cell, solar Controller, Battery (group) composition. If the output power is AC 220V or 110V, the inverter needs to be configured. The functions of each part are:
(a) Solar panels: Solar panels are the core part of solar power systems and the most valuable part of solar power systems. Its role is to convert the sun's radiation capacity to electricity, or to the storage battery, or to promote load work. The quality and cost of the solar panel will directly determine the quality and cost of the whole system.
(ii) Solar Controller: The role of the solar controller is to control the whole system working conditions, and the battery has been charged protection, over discharge protection. In the large temperature difference place, the qualified controller should also have the function of temperature compensation. Other additional functions such as the optical control switch, the time control switch should be the controller's optional.Black Solar Panel
(iii) Battery: Generally lead-acid batteries, small micro-systems, can also be used Ni-MH batteries, nickel-cadmium batteries or lithium batteries. The effect is to store the energy emitted by the solar panel when there is light and then release it when needed.Black Solar Panel
(iv) Inverter: In many cases, the need to provide 220VAC, 110VAC AC power. Because the direct output of solar energy is generally 12VDC, 24VDC, 48VDC. To provide power to 220VAC electrical appliances, the DC energy emitted from the solar power system needs to be converted into alternating current energy, so the AC inverter is required. In some cases, the need to use a variety of voltage load, but also to use the DC inverter, such as 24VDC power conversion to 5VDC of electricity (note, not simple buck).
The fabrication process of crystalline silicon solar cells: crystalline silicon solar cell "silicon" is one of the most abundant materials on our planet. Since 19th century, when scientists discovered the semiconductor properties of crystalline silicon, it almost changed everything, even human thinking. At the end of 20th century, our life is everywhere visible "silicon" figure and function, crystalline silicon solar cell is in the last 15 years to form the fastest industrialization. The production process can be roughly divided into five steps: A, purification process B, pull Rod process C, slicing process D, battery process e, packaging process.Black Solar Panel
