    According to public data from Gaogong Industry Research Institute, the total shipments of China's energy storage market in 2024 will be 337.8GWh, a year-on-year increase of 64% compared to the total shipments of 206GWh in 2023. From the distribution of shipments in the market segments, the power storage market is still the main market, with a shipment share increase of nearly 7%, reaching 88% of the total share.     In terms of power storage, around March 2024, the 280Ah same-size battery cell 314Ah will gradually be mass-produced, and the 314Ah battery cell and the corresponding 20-foot 5MWh container will accelerate the penetration of the power storage market, with an annual penetration rate of over 40%, of which the highest monthly shipment penetration rate exceeds 90%. It is expected that the 314Ah battery cell will completely replace the 280Ah in 2025. In addition, the total capacity of energy storage batteries is 610GWh, of which the 280Ah and 314Ah cells with a specification of 71*173*207mm have a total capacity of 440GWh, which is expected to increase to more than 530GWh by 2025.     In February 2025, Gaogong officially released the list of energy storage lithium batteries in 2024:     In terms of communication energy storage, in 2024, only China Mobile Communications will bid for a centralized procurement of 1.19GWh lithium iron phosphate batteries. Therefore, in 2024, the energy storage lithium battery will only be 1.19GWh, a year-on-year decline of more than 85%.     In terms of household energy storage, since the general distribution capacity of household energy storage systems is 5~10kWh, the market is still dominated by 50Ah~100Ah cells, among which the more popular cell products are 50*160*118mm in size. In 2024, the shipment volume of household energy storage batteries will be 24.9GWh, a year-on-year increase of 24.5%, most of which will be sold to Europe.     In terms of portable energy storage, the portable energy storage market will shrink relatively in 2024, with annual shipments of 2.81GWh, a year-on-year decrease of nearly 30%, mainly affected by the overall market involution and the low technical threshold of portable energy storage products.     In terms of industrial and commercial energy storage, the industrial and commercial energy storage market will ship 11.8GWh in 2024, a year-on-year increase of 68.6%. Usually, when industry statistics are compiled, industrial and commercial data are generally attributed to power energy storage. The reason is that the usage attributes are consistent, all of which are derived from power dispatching needs, and the battery products used are consistent. Generally, 71*173*207mm battery cells and 1P52S battery packs are used, which are the same as power energy storage. There are only differences in application scenarios and operators. After the release of the "cancellation of mandatory storage" policy, the power storage market may be market-oriented. Then, whether for operator considerations or cost considerations, industrial and commercial energy storage may directly introduce 20-foot container-type [currently outdoor cabinet-type] to reduce costs.

What is a solar home energy storage system? After solar panels are installed, the energy they produce needs to be converted into electricity for your home. There are several ways to do this - you can stay connected to the grid, go completely off the grid, or have a hybrid power system.   A hybrid power system is one in which your solar panels remain connected to the power lines of the grid and have a backup battery system to store excess power. The solar energy absorbed by the solar panels is passed through the inverter to generate usable electricity. From there, the power either goes into your home, your battery, or the grid.   The benefit of a hybrid solar system is that you will always have power no matter the situation. With a backup battery, excess energy produced by your solar panels (but not used by your home) is stored in the battery. The battery will then provide you with power at night, when the sun is out, or during system outages or severe weather.   With a hybrid solar system, if you were to use up all the power in your battery, you have the ability to draw power from the grid.   Hybrid solar systems work by sending solar energy to your inverter, which then sends the energy to power your home. Extra energy not used to power your home will go into your home battery for storage.   This battery can provide power to your home when your solar panels are not producing energy. After all these steps, if there is still energy left, this energy is sent to the grid.

   The first generation of cells—silicon-based solar cells: the battle between monocrystalline and polycrystalline mainstreams     In 1839, French scientist A.E. Becquerel discovered the photovoltaic effect. When two pieces of platinum metal were clicked and inserted into an acidic solution, an electric current flowed between the electrodes, opening the door to the world of photovoltaics. By 1954, the United States produced the first monocrystalline silicon solar cell, marking the birth of photovoltaic power generation technology.     P-type and N-type iterations, leading XBC solar cell    In recent years, as the conversion efficiency of P-type solar cell has gradually approached the "ceiling", it has become a general trend to iterate from P-type to N-type technology. As far as the first half of 2023 is concerned, about 19.55% of N-type solar module projects have been targeted, and N-type shipments and production capacity of various photovoltaic companies have increased to varying degrees.     According to the latest module efficiency published on the report, the top-ranked modules are basically N-type solar panels.     On September 5th, 2023, LONGi announced its bet on XBC solar cells. TOPCON and HJT use new passivation contact structures to improve the passivation effect and thereby increase conversion efficiency. The front of XBC solar cells is not blocked by metal grid lines, eliminating the front metal electrode structure. , able to maximize the utilization of incident light.     Compared with HIT solar cells and XBC solar cells, TOPCON solar cells have better compatibility with P-type solar cells production lines and lower transformation costs. The transformation investment per GW is about 50-70 million, making it main layout object in the current N-type solar cell production capacity of photovoltaic companies .

Technology development trend of photovoltaic cells - P to N is imperative. Photovoltaic solar cells technology iterations continue to focus on "efficiency enhancement" + "cost reduction" At present, the average mass production efficiency of PERC cells is 23.2%, and the theoretical conversion efficiency limit is 24.5%. The mass production efficiency has already approached the theoretical limit of efficiency, making it difficult to increase the efficiency of PERC cells significantly. N-type solar cells technology iteration is imperative. Compared with traditional P-type solar cells, N-type solar cells have the advantages of high conversion efficiency, high bifaciality, low temperature coefficient, almost no light decay, and good weak light effect. Currently, mainstream N-type solar cells include TOPCon, HJT, IBC, etc. TOPCon has high limit efficiency and low cost of production line transformation; HJT has high mass production efficiency and a clear cost reduction route; IBC conversion upper limit is higher, but economical improvement still takes time. At present, the actual mass production yield rate of Topon is 24%-25.2%, and the actual mass production efficiency of HJT is about 25%, which is 1%-2% higher than that of P-type PERC cells.  

Monocrystalline PERC (Passivated Emitter Rear Contact) solar panels are considered to be very good and are widely used in the solar industry. Here are some reasons why mono PERC panels are highly regarded: High Efficiency: Monocrystalline PERC solar panels are known for their high energy conversion efficiency. The passivated rear contact enables the panels to capture and convert a greater amount of sunlight into electricity compared to traditional monocrystalline panels. Improved Low-Light Performance: PERC technology reduces the electron recombination at the rear surface of the solar cell, allowing the panels to perform better in low-light conditions. This means they can generate electricity even when the sunlight is not at its peak, such as in cloudy or shaded areas. Enhanced Temperature Coefficient: The temperature coefficient of a solar panel refers to its ability to maintain its energy production efficiency in high-temperature environments. PERC panels typically have a lower temperature coefficient, meaning they can maintain better performance in hot climates. Aesthetically Pleasing: Monocrystalline PERC solar panels usually have a sleek all-black design, making them visually appealing and a popular choice for residential and commercial installations. Longevity and Durability: Monocrystalline solar panels, including PERC panels, are known for their durability and long lifespan. They are built with high-quality materials and undergo rigorous testing to withstand harsh weather conditions such as wind, hail, and snow. Space Efficiency: Monocrystalline PERC panels tend to have higher efficiency ratings, allowing you to generate more electricity in a smaller area. This makes them a preferred choice when space is limited or when you aim to maximize your energy production within a given area. Overall, monocrystalline PERC solar panels offer a combination of high efficiency, improved performance, and aesthetic appeal. However, it's important to consider other factors such as cost, available installation space, and specific project requirements when choosing solar panels. Consulting with a reputable solar installer can help you determine if monocrystalline PERC panels are the right choice for your needs.
