Solar power system consists of solar battery, solar controller, battery ( Group) Composition. Such as the output power for ac 220 v or 110 v, also need to configure the inverter. The role of each part: ( A) Battery: general for lead-acid batteries, small miniature system, also can use nimh batteries, nickel cadmium battery or lithium battery. Its effect is when a light will be made by electricity, solar panels to released when needed. ( 2) Solar panel: solar panel is the core part of solar power generation system, is also a valuable part of the solar system. Its role is to convert the sun's radiation ability of electrical energy, or sent to stored in batteries, or promote work load. Quality and cost of solar panels will directly determine the quality and cost of the whole system. Mr. Shi monocrystalline silicon solar panels, 3) The role of the solar controller: solar controller is to control the working state of the whole system, and battery over charging protection, over discharge protection role. Where the temperature difference is bigger, qualified controller should also have the function of temperature compensation. Other additional functions such as light-operated switch, switch should be the option of the controller. ( 4) Inverter: on many occasions, all need to provide 220 vac, 110 vac ac power. As a result of the solar direct output is usually 12 VDC, 24 VDC, 48 VDC. To provide electricity to 220 vac electronics, needs to be given out by the solar power system DC can be converted into ac power, so you need to use DC - AC inverter. In some cases, it is necessary to use a variety of voltage of the load, also want to use DC - DC inverter, such as the 24 VDC power into 5 VDC power ( Note that is not a simple step-down) 。 The making process of the crystalline silicon solar cells, crystalline silicon solar cells and other Silicon & throughout; Is our one of the most abundant amount of material stored on the planet. Since the 19th century scientists found that after the semiconductor properties of crystalline silicon, it changed almost everything, even the human mind. The end of the 20th century, our life everywhere & other; Silicon & throughout; The form and function, industrialization of crystalline silicon solar cell is nearly 15 years the fastest. The production process can be roughly divided into five steps: a, b, pull rods, purification process c d, batteries, slicing process e, encapsulation process.
