Advantages of Photovoltaic Energy Storage Systems
The photovoltaic energy storage system is a system that uses solar energy for photovoltaic energy storage and power generation. Simply put, a photovoltaic energy storage system consists of two major pieces of equipment: photovoltaic equipment and energy storage equipment. Photovoltaic equipment absorbs solar energy and converts it into electricity. The energy storage device will store the electrical energy generated by the photovoltaic device. When the power of the photovoltaic system is insufficient, the energy storage system will convert the stored electrical energy into the required AC power supply grid through conversion. Specifically, it can be divided into photovoltaic off-grid power generation systems, on-grid and off-grid energy storage systems, photovoltaic grid-connected energy storage systems, and micro-grid energy storage systems.
The advantages of photovoltaic energy storage systems are reflected in the following three aspects.
1. High power generation efficiency and low cost
The photovoltaic equipment of the photovoltaic energy storage system can absorb solar energy and convert it into electrical energy during the day. The energy storage device will store this electrical energy, and then convert the stored electrical energy into alternating current required by the grid at night and release it. This realizes the self-generation and self-use of photovoltaic power generation to a certain extent, which not only improves the efficiency of power generation, but also converts solar energy into electric energy, which greatly reduces the cost of power generation and electricity consumption.
2. Provide pure electric energy to help energy saving and emission reduction
Photovoltaic energy storage power generation system can convert solar energy into electrical energy and store it, and when needed, convert the stored electrical energy into alternating current required by the grid and release it for use. The electricity provided by this system is converted using renewable, cleaner solar energy, which saves energy to a large extent. In addition, the power generated by this power generation system has fewer harmonics and is more pure power. It can not only achieve energy saving and emission reduction, but also improve the quality of the power grid.
3. It can improve the security of the power grid
The photovoltaic energy storage system can realize the flexible adjustment of electric resources, and can provide corresponding protective functions for the power grid in the event of a failure or emergency in the power grid, which greatly improves the flexibility and safety of the utilization of power resources. It can also save non-renewable energy, improve the utilization rate of renewable energy, and realize the two-way flow of energy storage and power generation.
