How solar cells generate electricity
Inverter: in many occasions, the need to provide 220VAC, 110VAC AC power supply. As the direct output of solar energy are generally 12VDC, 24VDC, 48VDC. In order to provide electrical energy to the 220VAC, it is necessary to convert the DC power from the solar power system into AC power, so the DC-AC inverter is needed. In some cases, the need for the use of a variety of voltage load, but also to use the DC-DC inverter, such as the power of the 24VDC can be converted into 5VDC power (note, not a simple Buck)
(two) solar controller: the role of solar controller is to control the working state of the whole system, and the battery overcharge protection, over discharge protection. Where the temperature difference is larger, the qualified controller should also have the function of temperature compensation. Other additional features such as a light operated switch and a timing switch should be optional;
Solar panel: solar panel is the core part of the solar power system, is also the most valuable part of the solar power system. Its role is to convert the sun's radiant power into electrical energy, or sent to storage batteries, or to promote the work load. The quality and cost of solar panels will directly determine the quality and cost of the whole system;
Solar power system consists of solar cells, solar controller, battery (group). Such as the output power for AC 220V or 110V, also need to configure the inverter. The role of each part:
