Classification and function of discount solar panels

Classification: crystalline silicon cell board: polycrystalline silicon solar cells, single crystal silicon solar cells.

Amorphous silicon cell plate: thin film solar cells, organic solar cells.

Chemical dye battery plate: dye sensitized solar cells.

Power generation system.

     Discount solar panels: solar power system is composed of solar cells, solar controller, battery (Group). If the output power supply for AC 220V or 110V, also need to configure the inverter.

     The function of each part is:

     (a) discount solar panels: discount solar panels are the core part of the solar system, and are the most valuable part of the solar system. Its role is to convert solar energy into electrical energy, or stored in a storage battery, or to drive the load (with electrical appliances). The quality and cost of discount solar panels will determine the quality and cost of the whole system.

     (b) solar controller: the function of the solar controller is to control the working state of the whole system, and the function of the battery has been protected by over charge and over discharge protection. In the larger temperature difference, the qualified controller should also have the function of temperature compensation. Other additional features such as optical switch,time control switch should be optional controller.

     (c) battery: General lead-acid batteries, it has two kinds, respectively is 12V and 24V, small or micro systems, but also be used nickel metal hydride batteries, nickel cadmium battery or lithium battery. The function is to store the electric energy of the discount solar panels when the light shines, and then release it when needed.

     (d) the inverter: On many occasions, we are required to provide AC220V, AC110V AC power. Because of the direct solar energy output are generally DC6V, DC12V, DC24V, DC48V.In order to provide power to the AC220V, it is required to convert the DC power to AC power, so it is required to use the DC-AC inverter. In some occasions, the use of a variety of voltage load, it is also used in DC-AC inverter, such as the 24VDC of the power to convert into 5VDC electric energy (note, not a simple buck).
