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).
