Composition of solar power generation system:
Solar panel: This is the core part of the system, responsible for converting solar radiation energy into electrical energy. It is usually packaged with high-efficiency solar cells that can effectively absorb light energy and generate electromotive force.
Controller: The function of the controller is to manage the operating status of the entire system, including adjusting the output of the solar panel, protecting the battery from overcharging or overdischarging, and may have other functions such as light control and time control switches.
Battery: A battery is used to store the electrical energy generated by solar panels, in order to provide power when there is no sunlight exposure. It needs to meet the requirements of low self discharge rate, long service life, and strong deep discharge capability.
Inverter: If the system needs to supply power to AC loads, an inverter is essential as it converts DC electricity to AC electricity to meet the needs of most household appliances.
AC distribution cabinet: In some systems, AC distribution cabinets are used to manage the access to the power grid and the distribution of electrical energy, ensuring the normal power supply of the system.
Photovoltaic bracket: used to support and install solar panels, ensuring that they face sunlight and remain stable.
Auxiliary equipment: This may include automatic tracking systems, automatic cleaning systems, etc., to improve the efficiency and reliability of the system.
When designing a solar power generation system, factors to consider include the amount of solar radiation in the geographical location, load demand, output voltage type, expected operating time, continuous power supply demand, and the nature of the load (resistive, capacitive, or inductive).
