Solar power system consists of solar battery, solar controller, battery (group). Such as the output power for ac 220 v or 110 v, also need to configure the inverter. The role of each part as follows:
(a) solar panel: solar panel is the core part of solar power generation system, is also a valuable part of the solar system. Its role is to convert the sun's radiation ability of electrical energy, or sent to stored in batteries, or promote work load. Quality and cost of solar panels will directly determine the quality and cost of the whole system.
(2) solar controller: solar controller is used to control the working state of the whole system, and battery over charging protection, over discharge protection role. Where the temperature difference is bigger, qualified controller should also have the function of temperature compensation. Other additional functions such as light-operated switch, switch should be the option of the controller.
(3) battery: general for lead-acid batteries, small miniature system, also can use nimh batteries, nickel cadmium battery or lithium battery. Its effect is when a light will be made by electricity, solar panels to released when needed.
(4) inverter, on many occasions, all need to provide 220 v AC, 110 v AC AC power. Due to the direct output of solar are generally DC 12 v, 24 v DC, 48 v DC. To provide electricity to 220 v AC electrical appliances, needs to be given out by the solar power system DC can be converted into AC power, so you need to use DC - AC inverter. In some cases, it is necessary to use a variety of voltage of the load, also want to use DC - DC inverter, such as the 24 v DC power into 5 v DC power (note that is not a simple decompression).
