Rooftop Solar Panels

Functions of the components of solar power system
 A solar power system consists of solar panels, solar  controller and battery. If the output power is 220V AC or 110V, the inverter  should add to the configuration. The roles of each component:

?Solar Panel: solar panel, the most indispensable and  valuable part of the solar power system, plays a role to convert the sun  radiation to electrical energy, to sent to the storage battery, or to promote  the workloads.

?solar controller: the role of the solar controller  is to control the working state of the system and provide the battery  over-charging protection and over-discharging protection for the storage  battery. The controller should also have the functions of compensating  temperature in areas where large temperature gap exists and having  light-control switch, time-control switch for the controller.

?battery:Gel battery is the most common one , its  function is to store up the absorbed energy from the solar panel and to release  energy is usage.

?inverter: the inverter should provide 220VAC,110VAC  power on many occasions. Due to the direct solar energy output are generally  12VDC,24VDC,48VDC, in some cases, when comes to a variety of voltage load,  DC-DC inverter is needed,e.g.convert the 24VDC power into the power  5VDC(note:that is not a simple step-down).
