Rooftop Solar Panels

Functions of the components of solar power system  A solar power system consists of solar panels,Website:http://www.cnsourcelights.com, 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).
