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:

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 solar energy 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.

(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.

(three) battery: lead-acid battery in general, there are generally 12V and 24V these two kinds of small micro system, can also be used nickel metal hydride batteries, nickel cadmium batteries or lithium batteries. Its role is in the light of the solar panels will be issued by the energy stored up, to be released when needed.

(four) inverter: in many occasions, the need to provide AC220V, AC110V AC power supply. As the direct output of solar energy are generally DC12V, DC24V, DC48V. In order to provide electrical energy to the AC220V, 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-AC inverter, such as the power of the 24VDC can be converted into 5VDC power (note, not a simple buck).
