■■ Wide application
The solar power system, widely used in a variety of electrical lighting, is especially suitable to remote villiage&sch ool&hospital, private residential, island, army, and outside working.
■ Functions of the Components of Solar Power Systems
A solar power system consists of solar panels, solar controller and battery (group). 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 alsohave the functions of compensating temperature in areas where large temperature gap exists and having light-control switch, time-control switch for the controller.
☆ Battery: lead-acid battery is the most common one, its function is to store up the absorbed energy from the solar panel and to release energy in 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, DCDC inverter is needed, e.g. convert the 24VDC power into the power 5VDC (note: that is not a simple step-down).
■ Factors needs to be considered for the Design of Solar Power System
☆ What is the applicable area for the solar power system? What is its longitude and latitude?
☆ How many KWH need the system to provide per day?
☆ What about the Max load of the solar power system?
☆ What is the output voltage, DC or AC?
☆ What about the backup rainy days for the solar power system?
