Hybrid solar system, referred to as photovoltaic energy storage system, is a system that uses the solar photovoltaic effect to convert light energy into electrical energy and stores the electrical energy through energy storage equipment for subsequent use. This system integrates the two core technologies of photovoltaic power generation and energy storage. It not only achieves sustainable utilization of energy, but also solves the problem of unstable power supply through power dispatching, becoming an important innovation in the modern energy field.

Operating principle of solar photovoltaic energy storage system

The operating principle of the solar photovoltaic energy storage system mainly includes the following steps:

Photovoltaic panels absorb sunlight and convert the light energy into direct current through the photovoltaic effect. When sunlight strikes the surface of a photovoltaic panel, photons excite electrons in the panel to form an electric current, thereby converting light energy into electrical energy.

Direct current is sent to energy storage devices for storage. Energy storage equipment usually uses high-efficiency energy storage technologies such as lithium-ion batteries and sodium-sulfur batteries to store electrical energy in the form of chemical energy for later use.

When electricity is needed, a power inverter converts the DC power stored in the energy storage device into AC power. The inverter has multiple working modes and can perform intelligent scheduling according to user needs and power supply conditions to ensure stable power supply.

AC power is connected to the load through the power grid or directly to meet the user's power needs. When sunlight is insufficient or power demand peaks, the electrical energy in energy storage devices will play a key role in making up for the lack of power supply.
