Solar power generation systems consist of solar cells, solar controllers, and battery (group). If the output power supply is 220V or 110V, it is also necessary to configure the inverter. The role of each part is:(1) Battery: Generally lead acid batteries, small micro-systems, also available nickel-hydrogen batteries, nickel-cadmium batteries or lithium batteries. Its function is to store the electric energy emitted by the solar panel when there is illumination, release it again.
(2) Solar panels: Solar panels are the core part of the solar power system and the highest value in the solar power system. Its action is to convert the sun's radiation capabilities into electrical energy, or to store it in the battery or drive the load. The quality and cost of solar panels will directly determine the quality and cost of the entire system.

(3) Solar Controller: The role of the solar controller is to control the working state of the entire system, and the battery is overcharged by overcharge, and the operation of over-discharge protection. Where a large temperature difference, the qualified controller should also have a function of temperature compensation. Other additional functions such as optical control switches, the time-control switch should be optional for the controller.
(4) Inverter: In many cases, it is necessary to provide 220VAC, 110VAC AC power supply. Due to the direct output of solar energy is 12VDC, 24VDC, 48VDC. In order to provide electrical energy to 220VAC, the DC power emitted by the solar power system is required to convert the DC power energy, so the DC-AC inverter needs to be used. In some cases, when multiple voltage load is required, the DC-DC inverter is also used, such as electrical energy converting 24VDC electrical energy into 5VDC (note, not simple buck).
Crystal silicon solar cell production process:
Crystal silicon solar cell
“silicon”It is one of the most abundant materials in our planet. Since the semiconductor characteristics of crystalline silicon have been discovered since the 19th century scientists, it almost changed everything, and even human thinking. At the end of the 20th century, we can see every life in our lives.“silicon”The figure and role, crystal silicon solar cells are the fastest in the past 15 years. The production process can be roughly divided into five steps: a, purified process B, pull rod process C, slice process D, battery process E, package process.
