The role of the various parts:
       (A) solar panel: solar panels and solar power generation system is the core part of the solar system, the highest value. Their role is to the sun's radiation is converted to electrical energy stored in batteries or sent to, or Promote the work load.
       (B) solar controller: the role of the solar controller to control the entire system, and played a battery charge protection, over-discharge protection. In the large temperature difference, also qualified with temperature controller Compensation. Other additional features such as photo-controlled switch, when the switch should control the controller is optional;
       (C) batteries: General for lead-acid batteries, small micro-system, can also be used nickel metal hydride batteries, nickel-cadmium batteries or lithium batteries. The construction of which is light in there when the solar panels will be issued by the energy stored up, the need of When re-released.
       (D) Inverter: direct solar energy output are generally 12VDC, 24VDC, 48VDC. To be able to provide the 220VAC electrical power, solar power generation system will need to be issued by the DC can be converted to electrical energy exchange, requiring the use of DC-AC Inverter.
       Solar power generation system needs to be considered:
       1, the solar system where the use? Solar radiation to the situation?
       2, the power system load odds?
       3, the system is the number of output voltage, DC or AC?
       4, the system need to work how many hours a day?
       5, in case of exposure to sunlight does not rain, the system need to supply the number of days in a row?
       6, load, pure resistive, capacitive or inductive, the current start how much?
       7, the number of system requirements.
