In recent years, the market demand for integrated PV modules + energy storage systems has been growing. According to MarketsandMarkets, the global market for integrated PV modules + energy storage systems will reach USD 10 billion in 2025.

The principle of solar power is the photovoltaic effect. When sunlight hits a semiconductor material, it creates electrons and holes on the surface of the material. These electrons and holes flow in response to an electric field, which creates an electric current.

The energy landscape is undergoing a transformation, and at the forefront of this shift stands a powerful duo: solar energy and energy storage. The coupling of these technologies, known as the solar + storage model, is rapidly gaining popularity, and for good reason.

These benefits are attracting the attention of a growing number of investors. According to Bloomberg New Energy Finance (BNEF), global investment in residential energy storage reached $15 billion in 2022, a 70% increase year-over-year.

Among the three major trends in the development of lithium batteries, high energy density is currently the most urgent need. With the increasingly high requirements for range and capacity in electric vehicles, energy storage and other fields, the energy density of lithium batteries has become the focus of industrial development.

A home energy storage system is a combination of solar panels, storage batteries and inverters. The solar panels convert sunlight into electricity, the storage batteries store the electricity, and the inverter converts the electricity into alternating current (AC) for home use.

According to the International Energy Agency (IEA), the global solar energy storage battery market reached $120 billion in 2023 and is expected to reach $600 billion by 2030.

Home energy storage systems are similar to micro energy storage power stations, and their operation is not affected by city power supply pressure. During low power consumption times, the battery pack in a home energy storage system can recharge itself for use during standby power peaks or power outages. In addition to being used as an emergency power source, since the home energy storage system can balance the power load, it can save household electricity costs to a certain extent.

The battery is the heart of the home energy storage system and is responsible for storing electricity. Home energy storage batteries usually use lithium-ion batteries, which have high energy density, long service life and good safety.

Energy storage batteries for wind energy, solar energy and other new energy sources: lead-acid batteries are energy storage batteries for wind energy, solar energy and other new energy generation systems, providing power when the power system is unstable. Other applications: lead-acid batteries also have applications in many other fields, such as
