In-depth analysis of global household energy storage market demand
Mar 05, 2024 In-depth analysis of global household energy storage market demand
Content source: China Energy Storage Network PV-Tech 3060 In-depth analysis of household energy storage market demand Household energy storage is an integral part of the household power system under the energy revolution. The advantages of household energy storage systems include providing backup power to cope with grid outages, balancing energy supply and demand, improving self-sufficiency and reducing electricity bills. Stimulated by multiple factors, the demand for household energy storage continues to be strong, and the global market is blooming in many places. The following will briefly analyze the household storage demand in regional markets such as Europe, the United States, Australia, South Africa, and Southeast Asia. Global: Europe’s destocking growth slows down, while emerging markets take over and grow rapidly From the perspective of the global market, the global household storage market will have 15.6GWh of newly installed capacity in 2022, a year-on-year increase of 136.4%, more than doubling growth, and is expected to maintain a sustained rapid growth trend in the medium term. As the global energy transformation strategy continues to advance, there is a time and space mismatch between power supply and demand. The aging of the power grid, local conflicts, extreme weather and other problems have intensified the contradiction, driving the demand for household energy storage to increase. At the same time, governments of various countries have provided strong support for household energy storage, which has improved the economics of household energy storage. It is expected that global household energy storage installed capacity, with Europe and the United States as the main markets, will continue to maintain an upward trend. Due to the superposition of multiple factors, household energy storage has become one of the most promising incremental markets. Rising electricity prices: Due to the maturity of energy storage technology and falling costs, energy storage will begin to grow rapidly in 2021. In 2022, due to the year-by-year increase in energy costs and electricity prices in Europe, coupled with the Russian-Ukrainian war and large-scale overseas power outages, residential electricity costs will be high + power supply will be stable Poor performance has led to high growth in household photovoltaics, which in turn has led to an unexpected explosion in the household energy storage market. Increased policy support: Tax exemptions and financial subsidies provide policy support. As residents’ electricity prices continue to rise, the economics of household savings have improved. Countries around the world have launched relevant policies to encourage household energy storage installations. Relevant policies can be divided into indirect tax exemptions and direct financial subsidies, thereby reducing household storage installation costs; with the further implementation of policies led by carbon neutrality and energy independence goals, energy sto...

Is there radiation, pollution and noise in photovoltaic power generation?
Mar 01, 2024 Is there radiation, pollution and noise in photovoltaic power generation?
Photovoltaic power generation is to convert light energy directly into direct current energy through the characteristics of semiconductors, and then convert direct current into alternating current that can be used by us through the inverter. Photovoltaic system is composed of photovoltaic modules, supports, DC cables, inverters, AC cables, distribution cabinets, transformers, etc., of which, the support is not charged, naturally will not produce electromagnetic radiation. The photovoltaic module and DC cable inside is DC current, the direction does not change, can only produce electric field, can not produce magnetic field. (Radiation comparison of various household appliances and photovoltaic modules) The electromagnetic radiation of photovoltaic inverters compared with household appliances is about the same as that of laptop computers, lower than induction stoves, hair dryers, refrigerators. Therefore, the construction of photovoltaic power stations will not only not cause harm to human health, but also provide green and clean high-quality energy for the earth, which is the future direction of human energy development. 1. The manufacturing process is not "energy intensive" Photovoltaic manufacturing industry mainly includes crystal silicon purification, silicon ingot silicon wafers, photovoltaic cells and photovoltaic modules four links. Among them, crystal silicon purification needs to be completed under high temperature conditions, will consume a lot of electricity, accounting for about 56-72% of the total energy consumption, is the most important chemical production process in the industrial chain, and "high pollution" from the production of high-purity polysilicon byproducts. Crystal silicon purification is indeed a large-scale, high-energy industry. However, this does not mean that photovoltaic products are high energy consumption, we also need to convert the total energy consumed in the production of photovoltaic modules into power consumption, and compared with the lifetime of the module. The "photovoltaic manufacturing industry Specification Conditions" issued by the Ministry of Industry and Information Technology in 2015 stipulates that the power consumption of the polysilicon production process must be less than 120 KWH/kg, and the new construction and expansion projects must be less than 100 KWH/kg, which should be closer to the current world advanced level of energy consumption. This conversion, in line with the national regulations of photovoltaic power consumption, the production of a watt of photovoltaic modules need 0.6-1.2 degrees of electricity. According to the 25-year life of photovoltaic modules, photovoltaic power generation is far greater than production consumption. 2.No light pollution Light pollution is threatening people's health. In daily life, people's common light pollution is mostly caused by the vertigo of pedestrians and drivers caused by the reflection of mirror buildings, and the discomfort caused by unreasona...

How to prevent photovoltaic roof from leaking?
Feb 29, 2024 How to prevent photovoltaic roof from leaking?
More and more users are installing photovoltaic power stations. When it comes to power stations/lithium batteries for solar panels, preventing water leakage is a top priority for factories. If the factory building is used as a photovoltaic power station, how should it be waterproofed? Or what should I do if the photovoltaic roof leaks? Causes of roof leakage Under normal circumstances, the initial investment in installing a photovoltaic power station is not small. If water leaks occur and the photovoltaic is dismantled and waterproofed again, the loss can be imagined. The main causes of roof leakage are as follows: 1. When installing photovoltaic brackets on concrete flat roofs or villa concrete slope roofs, use embedded bolts, expansion bolts or chemical anchor bolts to fix and install the photovoltaic brackets, which will destroy the original waterproof layer and cause rain leakage; 2. Because the roof color steel plates are exposed to the outside for a long time, they will rust, age, and leak. How to prevent when installing photovoltaic system(lithium batteries for solar panels)? When waterproofing the roof, we must adhere to the principle of "it should be directed rather than blocked" to ensure that the water can flow away smoothly when heavy rain accumulates, and the roof does not leak. During the installation process of photovoltaic brackets, make sure that the bracket base is not arranged perpendicular to the drainage direction and does not hinder the drainage of roof rainwater. When placing the bracket base directly on the existing roof during construction, ensure that the base is placed stably and neatly, and measures need to be taken to fix it to avoid overturning, slipping, etc., and to avoid conflicts between the base and the roof structure. The cascading relationship ensures the safety of the structure. In addition, try to avoid drilling holes in the roof. When drilling holes in the roof or the concrete slope roof of the villa, you must first determine the thickness of the perforated roof. In order to avoid damage to the roof by drilling, pouring is usually done on it. A certain thickness of concrete layer is used to fix the bracket using chemical anchor bolts after curing. In summary, waterproofing is the key to doing photovoltaics. Therefore, when installing photovoltaics, you must find a reliable and experienced installer. A reliable installer can control the waterproofing to have the same lifespan as the photovoltaic,so that the photovoltaic power station can play its full role. produce the greatest effect.

Photovoltaic system is composed of photovoltaic modules, supports, DC cables, inverters, AC cables, distribution cabinets, transformers, etc., of which the support is not charged, naturally will not produce electromagnetic radiation. Photovoltaic modules and DC cables, inside is DC current, the direction does not change, can only produce electric fields, can not produce magnetic fields. Although the output transformer is AC, the frequency is very low, only 50Hz, and the magnetic field generated is very low. Inverter is the direct current into alternating current equipment, which has a power electronic conversion, the frequency is generally 5-20KHz, so it will produce alternating electric field, so it will also produce electromagnetic radiation. The state has strict standards for the electromagnetic compatibility of photovoltaic inverters. The electromagnetic radiation of photovoltaic inverters, compared with household appliances, is about the same as that of laptops, lower than induction stoves, hair dryers, refrigerators. Therefore, the construction of photovoltaic power stations will not only not cause harm to human health, but also provide green and clean high-quality energy for the earth, which is the future direction of human energy development.

What's in the energy storage battery PACK?
Feb 27, 2024 What's in the energy storage battery PACK?
Content source: Energy storage box On the electrochemical energy storage track, lithium-ion energy storage is currently relatively mature in technology and has the fastest development momentum. Among them, lithium-ion battery battery PACK technology is an extremely important part. What exactly is a battery PACK? What does its complete production line look like? Let’s go to solidify these concepts! 01 What is a battery pack? Lithium-ion battery PACK, also known as battery module, is a lithium-ion battery manufacturing process that refers to connecting multiple lithium-ion single cell groups in parallel and series, taking into account the system mechanical strength, thermal management, and BMS. Matching issues. Its important technologies are reflected in the overall structural design, welding and processing process control, protection level, active thermal management system, etc. If two batteries are connected in series or parallel to form a specific shape according to customer requirements, it is called PACK. 02 The composition of the battery PACK The important components of the battery PACK include the five parts of the single battery module, electrical system, thermal management system, box, and BMS. ▷Battery module: If the battery PACK is compared to a human body, then the module is the "heart", responsible for the storage and release of electrical energy. ▷Electrical system: It is mainly composed of connecting copper strips, high-voltage wire harnesses, low-voltage wire harnesses, and electrical guarantee devices. The high-voltage wire harness can be regarded as the "artery blood vessel" of the battery PACK, which continuously delivers battery power to the end load. The low-voltage wire harness can be regarded as the "neural network" of the battery PACK, transmitting detection signals and control signals in real time. ▷Thermal management system: The thermal management system mainly has two methods: air cooling and liquid cooling, and liquid cooling can be divided into cold plate liquid cooling and immersion liquid cooling. The thermal management system is equivalent to installing an air conditioner on the battery PACK. The battery will generate heat in discharge mode. To ensure that the battery operates at a reasonable ambient temperature and improve the battery cycle life, the system temperature difference is generally required to be ≤5°C. ▷Box: Mainly composed of box, box cover, metal bracket, panel and fixing screws, it can be regarded as the "skeleton" of the battery PACK, playing the role of support, resistance to mechanical impact, mechanical vibration and environmental protection. ▷BMS: The abbreviation of "Battery management system", that is, the battery management system, can be likened to the "brain" of the battery. It is mainly responsible for measuring parameters such as voltage, current and temperature of the battery, as well as balancing and other functions. Data can be transferred to MES. 03 Features of Battery PACK ▷ PACK lithi...

The principle and advantage of photovoltaic power generation
Feb 23, 2024 The principle and advantage of photovoltaic power generation
The principle and advantage of photovoltaic power generation Solar photovoltaic power generation principle: Photovoltaic power generation is a technology that converts light energy directly into electrical energy by using the photovoltaic effect of semiconductor interface. The main core components of photovoltaic power generation are solar cells, and other components include batteries, controllers, and so on. Solar cells store sunlight, and then through a series of technical operations to convert its solar energy into electricity, the advantage of this technology is that as long as there is light, solar cells can collect and reserve sunlight. The process of converting solar energy into electricity mainly includes three steps: 1.After the solar cell absorbs a photon of a certain energy, an electron hole pair is generated in the semiconductor, which is called "photogenerated carrier", and the electrical polarity of the two is opposite, the electron is negatively charged, and the hole is positively charged. 2.Photogenerated carriers with opposite electrical polarity are separated by the electrostatic field generated by the semiconductor PN junction. 3.Grid connected pv system, that is, connected to the national grid. China's photovoltaic grid-connected power generation has been very mature, to encourage the conditions of regional industry and commerce and household, public buildings and other construction of photovoltaic power generation facilities, power generation for their own use at the same time can also enjoy the sale of electricity income. Solar photovoltaic power generation systems are mainly used in the following three major aspects: 1.To provide power for non-electric occasions, mainly for the majority of non-electric areas to provide electricity for the living production of residents, microwave relay stations and mobile phone base stations to provide power. 2.Solar daily electronic products, such as all kinds of solar chargers, solar street lights and solar lawn lights. 3.Grid-connected power generation, that is, connected to the national grid. China's photovoltaic grid-connected power generation has been very mature, to encourage the conditions of regional industry and commerce and household, public buildings and other construction of photovoltaic power generation facilities, power generation for their own use at the same time can also enjoy the sale of electricity income. Advantages of solar power: 1.Economic advantage: Solar energy is inexhaustible, and solar energy can generate electricity as long as there is light, which is very convenient; At the current level of technological development, the use of some solar energy has become economical. With the development of science and technology and the breakthrough of human development and utilization of solar energy technology, the economy of solar energy utilization will be more obvious.

Can photovoltaic power stations still generate electricity normally on cloudy or rainy days?
Feb 22, 2024 Can photovoltaic power stations still generate electricity normally on cloudy or rainy days?
Many friends have heard of photovoltaic power generation And know that it relies on light to generate electricity Both environmentally friendly and energy-saving Therefore, the country strongly promotes photovoltaic power plants Since photovoltaic power stations rely on light to generate electricity Then there is no sun on cloudy and rainy days Will our photovoltaic power station stop working? The picture above is a simple power generation diagram of a photovoltaic power station. After reading the picture, many people will ask: Photovoltaic power generation = solar power generation? In fact, there is a difference between them: photovoltaic power generation is only one type of solar power generation, and solar power generation also includes photochemical power generation, light induction power generation and photobiological power generation. Some friends may also ask, will installing photovoltaic power generation produce radiation to the human body? The answer is not only no, photovoltaic power generation can also reflect ultraviolet rays from the sun that are harmful to the human body, so it is very safe and reliable. Can power be generated normally on cloudy or rainy days? First of all, photovoltaic power generation relies on sunlight, and weather changes are crucial to its power generation work. However, on cloudy and rainy days when there is no sun, the photovoltaic power station does not completely stop working. Weak light can also play a certain role in the components. However, in some special cases, the solar radiation is too low, and the operating voltage of the photovoltaic power generation system If the starting voltage of the inverter cannot be reached, the system will not work. Although the photovoltaic power station cannot work hard for us on rainy days, it will not damage the photovoltaic modules. On the contrary, the rain can help us clean the modules. When the sun comes out again, the photovoltaic power station will work even harder to create wealth for you!
