太陽光発電システムにおける太陽電池の応用
High-performance energy storage batteries are of great importance to the development of photovoltaic industry. 鉛蓄電池との比較, リチウム 太陽 打者y はぁs advantages of high energy storage efficiency, high cycle life, long service life and low cost. Taking advantage の 太陽 battery as energy storage power supply, energy efficiency can be improved to about 90%, so it is very suitable for ある new energy storage device.
Principle of solar battery of Photovoltaic energy storage system
Lithium solar battery is an indispensable part of solar photovoltaic power generation system. Its main function is to store the energy of the photovoltaic power generation system and supply power to the load in the case of insufficient sunshine, night and emergency.
Common types of storage 12v 42ah Lifepo4 バッテリー have 鉛蓄電池, エネルギー貯蔵電池, alkaline batteries, 太陽 battery and super capacitor. 彼らです respectively applied in different situations or products. Lithium iron phosphate is one of the fastest growing 太陽 バッテリー. あt present, there are mainly the lithium iron phosphate batteries and ternary lithium battery.
しかし, そこで登場したのがリン酸鉄リチウム (LiFePO4). この最近の種類のリチウム溶液は、エネルギー密度が少し低かったものの、本質的に不燃性でした。. 他のリチウム化学物質よりも安全であることに加えて、, リン酸リチウム電池には多くの利点があります, especially for high power applications.Sometimes, リチウム電池の価格も非常に重要な要素です.
Solar batteries are an impressive upgrade for homeowners with solar power. They give you the ability to store the electricity you generate and use it when the sun goes down (or when the power lines go down).
“An average homeowner typically will draw 2 kilowatts maximum during an outage, そして平均 750 に 1,000 watts during the course of the outage,” he said. “This means a Brightbox will last for 10 に 12 時間, while a Powerwall will last for 12 に 15 hours.”
Solar Battery Cost
Solar batteries are currently on the expensive side. Solar batteries range from $5,000 に $7,000+, and from $400/kWh to $750/kWh. These prices reflect the battery itself and do not include the cost of installation or any additional equipment.
The basic requirement of solar photovoltaic power generation systems for energy storage
Solar power generation system has high cost, low conversion efficiency and strong changes with the environment, so it has high requirements for energy storage. The service life of solar photovoltaic power generation system is generally 20 年, it required the energy storage to have long service life, 安定したパフォーマンス, high energy efficiency and strong ability to adapt to the environment.
Performance analysis of solar battery:
12v 42ah Lifepo4 バッテリー is a new type of secondary power supply developed in recent years. それ』s characterized in large input and output power, wide operating temperature range, メモリー効果なし, メンテナンスフリー, と 2000 times of charge and discharge service life, safety and environmental protection, becoming the leading role of chemical batteries.時々, 車のリチウム電池も重要な役割を果たすことができる.
太陽 battery voltage platform for 3.2 V, は 2 times more than lead-acid battery, and the volume ratio energy 4 ～ 5 times that of lead-acid battery. 私f use 太陽 batteries instead of lead-acid batteries used in photovoltaic power generation system, can greatly reduce battery of space そして reduce maintenance workload. In terms of photovoltaic energy storage efficiency, 太陽 batteries has obvious advantages.
Application of solar battery in photovoltaic power generation
As renewable energy sources such as wind and photovoltaic power generation industry fast development, the pollution of power network disturbance, randomness caused by light そして the wind problems become increasingly serious.
以来 2011, based on リチウムポリマー電池 chemistry textbook development testing and application of energy storage system, people はぁve been conquered the energy storage system in one application problem. Photovoltaic module array uses the photovoltaic effect of solar panels to convert light energy into electrical energy, and then charges the リチウムポリマー電池 パック. The inverter converts direct current to alternating current to power the load. Intelligent controller according to sunshine intensity and load changes, constantly switch and adjust the working state of the battery group. ○n the one hand, the adjusted electric energy directly to dc or AC load.
○n the other hand, the excess electric energy will be transferred to the storage battery group when the power generation cannot meet the needs of the load. the controller sends the electric energy of the リチウムポリマー電池 to the load to ensure the continuity and stability of the whole system. The grid-connected inverter system is composed of several inverters, which turns the direct current in the battery into the standard 380V mains and connects to the low-voltage power grid on the user side or sends it to the high-voltage power grid through the boost transformer Lithium battery pack plays two major roles of energy regulation and load balance in the system at the same time. It converts the electric energy output of photovoltaic power generation system into chemical energy and stores it in case of insufficient power supply.
Solar battery can improve the energy storage efficiency of photovoltaic system to 95%
The cost per kilowatt hour of 太陽 battery is about 0.8-0.85 yuan. 現在のところ, a major factor restricting the commercial development of energy storage is high cost. With the improvement of technical level, the cost per kilowatt hour of energy storage is decreasing year by year. Lithium iron phosphate batteries can increase the energy storage efficiency of photovoltaic systems to 95%, far more than the traditional lead-acid batteries of 70 に 80%. あnd with 2,000 charge and discharge service, life lithium iron phosphate batteries are expected to improve the efficiency of solar power generation systems, and help reduce their installation and maintenance costs.
結論:
The rapid development of solar photovoltaic power generation system puts forward higher requirements on energy storage system. 太陽 battery energy storage of high efficiency Life is long good charge and discharge performance characteristics determine. 私t is very suitable for as a new energy storage with power lithium iron phosphate batteries. Photovoltaic energy storage system energy efficiency is high. It also has a long the charge and discharge service life, ある stable operation and good application prospect.
