Does the electricity generated by photovoltaic need to be stored?
Mar 15, 2024 Does the electricity generated by photovoltaic need to be stored?
When doing household photovoltaic system promotion, people often ask, does the electricity generated by photovoltaic need to be stored? How do you use electricity at night? To understand these problems, we need to understand the concepts of on-grid system and off-grid system. 1. Grid-connected system.      The grid-connected system requires the photovoltaic system to be connected to the power grid, and the grid-connected system can be divided into "self-use, surplus electricity online" mode and "full Internet access" mode.      Residential grid-connected power generation system is the installation of solar modules on the roof of residents, the system is connected to the grid, and the power supply task is shared. In the case that the amount of sunlight radiation reaches the power generation requirements, the inverter in the system converts the direct current generated by the photovoltaic power generation system into alternating current, which directly supplies power to the residential household load, and the insufficient part is supplemented by the municipal power supply, and the photovoltaic power generation is greater than the residential household electricity consumption, the remaining power is incorporated into the grid. This is the so-called "spontaneous self-use, surplus electricity online" mode.      Users can also choose to directly integrate all the power generated by the photovoltaic system into the grid. All the electricity needed for household load is supplied directly by the grid. This is the "full access" model. Characteristics of grid-connected system: 1) Connect to the power grid, and upload part or all of the electricity to the power grid. 2) Power grid outage, photovoltaic power generation also stopped. Because the inverter has anti-island, that is, the power grid company requires: power grid power failure, photovoltaic power must also be immediately cut off. The main concern is safety. 3) Residents still rely on mains electricity at night. 4) No energy storage device.      Therefore, the grid-connected power generation system needs to rely on the grid, and the generated energy is transmitted to the grid, which does not need to be stored. At night, we still rely on the grid, on the mains. 2. Off-grid system.      Principle and composition of off-grid system. The working principle of the off-grid power generation system is very similar to that of the grid-connected power generation system, except that the power of the off-grid system is not transmitted to the public grid and is directly consumed by the load. Taking into account the volatility of photovoltaic power generation, such as power generation during the day and no power generation at night, good sunny day power generation less or no power generation in rainy weather, residents off-grid power generation system needs to be equipped with batteries (groups). The off-grid solar power generation system co...

The major models of
Mar 14, 2024 The major models of "photovoltaic + agriculture"
New energy + new agriculture, one represents the future of green transformation and development, and the other represents the foundation of the national economy and people's livelihood. Photovoltaics have given new vitality to the most traditional agriculture. Photovoltaic agriculture refers to a business model in which agricultural management facilities (or units) are scientifically designed and rationally grafted with photovoltaics in order to achieve multiple uses in one land and increase unit land output during the practice of agricultural production. During the design, construction and operation of photovoltaic power stations, space necessary for agricultural planting and breeding should be reserved to ensure that while the photovoltaic power station generates electricity normally, it can meet the physiological needs of plants and animals, achieve the effects and benefits of agricultural and photovoltaic complementation, and achieve the integration and innovation of ecological agriculture and circular agriculture technology models provide strong technical support for sustainable agricultural development. "Photovoltaic + agriculture" is an emerging form of agriculture. It not only solves the problem of power supply required for water extraction and irrigation machinery, avoids the competition between the photovoltaic industry and agriculture for land, but also sells the excess electricity to the national grid. At present, there are four main modes of photovoltaic agriculture, namely photovoltaic planting, photovoltaic breeding, photovoltaic water conservancy, and photovoltaic cottages, which are divided into mushroom photovoltaic, fishery and photovoltaic complementary, vegetable (fruit) photovoltaic, livestock and poultry (pastoral) photovoltaic, Linguang, medicinal photovoltaics, ecological photovoltaics, water conservancy photovoltaics, etc.In the current wave of rapid development of the  photovoltaic industry, photovoltaic agriculture plays an important role and has broad development prospects. 1. Photovoltaic + Vegetable/Fruits Organically combine rooftop photovoltaic power generation with agricultural planting under the shed to drive the transformation and upgrading of the agricultural industry. In terms of crops, aerospace vegetables or shade-loving plants can be grown. This type of  project can also do some tourism agriculture.   2.Photovoltaic + Breeding industry Photovoltaic plus breeding industry can be used for free-range breeding or breeding sheds. It can breed sheep, pigs, chickens, dairy cattle, beef cattle, rabbits, etc. Most of them are herbivorous animals.   3.Photovoltaic + Fishery Utilizing the vast area of the fish pond, solar panels are installed on it to generate electricity. The photovoltaic modules are arranged three-dimensionally above the water surface, and aquaculture is carried out below.It is dual-purpose in one place, and the profit is significantly higher than that of pure aquaculture.At pre...

Energy storage system inverter learning
Mar 12, 2024 Energy storage system inverter learning
1. Basic introduction to energy storage systems Battery Energy Storage System (BESS) mainly consists of energy storage batteries, power conversion system (PCS), battery management system (BMS), and energy management system (EMS). Partially composed (as shown in Figure 1). A complete energy storage system BMS should include a plug-in BMS, a battery cluster BMS, and a system BMS. Especially for large-scale energy storage systems, a three-level BMS can avoid voltage imbalance and resulting overcharge or overdischarge to the greatest extent. According to the different levels of PCS, power frequency boost PCS can be divided into single-stage and double-stage. Among them, single-stage PCS is divided into two-level, three-level and multi-level according to the output level. The more levels, the higher the output power quality. The overall architecture of EMS can be divided into support platform and application software. The support platform mainly includes measurement terminals, transmission channels, computers, databases, etc. The application software includes data collection and monitoring, energy management, and network analysis (the energy storage system control structure is shown in Figure 2). 2. Classification of common energy storage system inverters Currently common energy storage inverters can be divided into centralized, distributed, and string types. 2.1) Centralized energy storage inverter solution (see Figure 3) The centralized energy storage inverter solution is mainly used in large-scale ground power stations. The topology diagram from right to left is: high-voltage switch cabinet-transformer-2* energy storage converter-2* bus cabinet-battery cluster. After converging from the DC side, the inverter is centralized. The system topology adopts DC-AC one-level full-bridge inverter. 2.2) Distributed inverter solution (see Figure 4) Figure 4 shows the topology diagram of the distributed energy storage inverter: transformer-string inverter-16*battery cluster (maximum). The converging cabinet is omitted, and the AC side is converging after the DC side inversion is completed. Adopt DC-AC one-level conversion. Figure 5 is the topology diagram of the distributed inverter. The main difference from Figure 4 is the design of the breakpoint. Figure 5 is the DC side isolation switch + fuse solution, and Figure 4 is the AC side circuit breaker solution. The disadvantage in Figure 5 is that the inverter fails and the upper-level switch needs to be disconnected. The advantage is that the DC side has short-circuit protection. The solution in Figure 4 can disconnect the AC side and maintain a single module. The AC side switch is outside the PCS module and the wiring is complicated. Comparison between centralized and distributed inverters 2.3) String inverter solution (see Figure 6) Not only does it manage one cluster per cluster, it also installs an optimizer on the battery PACK to implement energy management down to the battery module level. The available ca...

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.
