Description

Technical Field

[0001] This utility model relates to the field of photovoltaic modules, specifically an energy storage photovoltaic module. Background Technology

[0002] Solar power generation utilizes the photovoltaic effect of semiconductors to directly convert light energy into electrical energy. It boasts advantages such as safety, reliability, zero noise, low pollution, and no fuel consumption, making it the most ideal comprehensive solar energy application technology today. Photovoltaic modules are currently the most widely used solar power generation equipment. A typical crystalline silicon photovoltaic module generally consists of dozens of crystalline silicon photovoltaic cells. These cells are arranged and connected according to a certain pattern, and finally encapsulated using materials such as glass plates and encapsulating films to form an integrated photovoltaic panel. With the addition of a frame and junction box, it forms a photovoltaic power generation module, becoming the smallest power generation unit of a photovoltaic power station, capable of generating electricity and outputting power to the outside world.

[0003] Generally, a photovoltaic (PV) power station consists of hundreds or thousands of PV modules. These modules are connected in series or parallel to form a unified power generation system. When there is solar radiation, all modules generate electricity and output it externally (usually to the power grid or large energy storage devices). The output electricity can be used directly or stored. The operation of a PV power station is affected by the external power grid or energy storage. When the power grid is regulated, the PV power station may stop working. At this time, all PV modules will be unable to generate electricity due to the disconnection of the PV power station system, and the power generation utilization rate of each PV module will decrease.

[0004] Photovoltaic power generation systems can be divided into grid-connected photovoltaic (PV) power generation systems and stand-alone PV power generation systems based on whether they are connected to the grid. Grid-connected PV power generation systems mainly refer to PV systems that are connected to the power grid and subject to grid dispatch, such as various centralized or distributed PV power plants. Stand-alone PV power generation systems mainly refer to various PV power generation systems that operate independently of the power grid, such as solar streetlights and rural household PV power supplies.

[0005] Both grid-connected and stand-alone photovoltaic energy storage systems store excess electrical energy through batteries. Current methods require a dedicated room to house the batteries, which are then connected to the solar power system via cables.

[0006] Energy storage systems, as an effective way to store electrical energy, can be divided into four categories: mechanical energy storage, battery energy storage, electromagnetic energy storage, and phase change energy storage. Battery energy storage is currently a mature, widely used, and low-cost energy storage technology. Commonly used batteries include lead-acid, lead-carbon, and lithium batteries. These systems require external batteries, which occupies additional installation structure and space; or they are directly attached to the back of the module, exposing the batteries to the environment, making them susceptible to impacts from external objects or rainwater corrosion, leading to battery damage. Therefore, it is crucial to develop an integrated energy storage photovoltaic module that overcomes these drawbacks. Utility Model Content
