2. Working Principles and Technical Characteristics of Storage Solar

(1) Working Principles

A storage solar system primarily consists of solar panels, energy storage devices, and power conversion equipment. Solar panels convert sunlight into electrical energy, and power conversion devices transform direct current (DC) into alternating current (AC) for user consumption or grid integration. When solar energy generation exceeds immediate usage, surplus energy is stored in energy storage devices such as batteries, supercapacitors, or pumped storage power stations. During periods of insufficient sunlight or at night, the storage devices release energy to meet user demand.

(2) Technical Characteristics

1. Renewability and Environmental Friendliness: Solar energy is an inexhaustible renewable resource. Storage solar systems do not produce any pollutants during operation, making them environmentally friendly.

2. Independence and Reliability: Storage solar systems can operate independently, without relying on traditional grids, making them valuable in remote or unstable grid areas. The storage devices also provide backup power, enhancing system reliability.

3. Flexibility and Scalability: Storage solar systems can be flexibly configured to meet various power demands and can be easily expanded or upgraded to adapt to future energy needs.
