What Is The Home Solar Storage Systems Market Trend For 2023?
(Last Updated On: 28/02/2023)
What Is The Home Solar Storage Systems Market Trend For 2023?
Home solar storage installations are expected to increase dramatically in the next few years. In 2021, the global installed energy of home solar storage was 6.4GWh, and it is expected to exceed 15GWh in 2022, an increase of more than 134% year-on-year. This trend is being driven by the energy inflation crisis and geopolitical conflicts in Eastern Europe, and electricity prices have increased significantly. It is optimistically estimated that global installed home solar storage is expected to reach 100GWh in 2025.
But what are the main market trends for this industry in 2023? In this blog post, we’ll take a look at some of the most important trends to watch for in 2023. So if you’re thinking about doing home storage system business, read on!
1. What’s the main market trend for home solar storage systems in 2023?
The answer is All-In-One home energy storage system, High energy battery system and High voltage battery system.
Why All-In-One home energy storage system is the future direction for home solar storage systems?
In home energy storage market, the split type (battery + Inverters) is currently more popular while all-in-one system home energy storage will soon take over as they offer increased efficiency for homes with high demand electricity needs like electric cars do! This type of all-in-one system includes everything you need in one package, so you don’t have to worry about buying separate components.
The new, all-in-one system is an exciting advancement for manufacturers looking to streamline their production process. The plug-and-play nature makes it easy as can be with no need for on-site docking or debugging which means that end users will have more fun using this type of product!
The all-in-one system is a game changer for markets. The highly integrated feature eliminates the need to install additional photovoltaic inverters, which reduces the hardware cost on the one hand, saves one-time equipment investment, simplifies installation, saves installation costs, and facilitates after-sales maintenance, effectively reducing subsequent software costs. According to our calculation, the all-in-one optical storage machine can save about USD 155 /KWH compared with the split scheme – not bad right?
The all-in-one system are the streamlined production and the fact that a single supplier provides both the batteries and inverters. This reduces time and labor costs in testing, installation, and maintenance. Additionally, this type of system is easier for consumers to use as it requires no additional components or hardware.
With an All-In-One home energy storage system, the battery and inverter go through the same certification process. This makes it easier and faster to get product certified.
The Bonnen engineering team has been researching the All-In-One home energy storage system for earlier days that can meet all of these features. You’re free to explore our detailed tech on this system if you like!
Why High energy Battery is more popular in-home solar storage system?
A high energy battery enables people to store solar power for longer periods of time. The higher energy battery means you can store a lot more excess solar power into your system, which will sustain relatively much longer during outages. This saves on electricity costs! A high energy battery also enables longer periods of time between charges, which is great for people who want to use solar power but live in an area with limited sunlight.
The system energy is expected to gradually increase as global middle-class customers continue their growth in Europe and America. The system energy is expected to gradually increase from 15kWh currently up 20+ kWh by 2023.
Why High-Voltage Battery system is gradually replacing low voltage battery system?
At present, the European household storage market, especially the Nordic and German-speaking markets, is experiencing product iteration from low-voltage to high-voltage systems. The efficiency of the high-voltage energy storage system is about 4% higher than that of the low-voltage energy storage system.
2. What will be the development for home solar batteries in 2023?
When batteries are charged and discharged, chemical reactions occur that generate heat. If too much heat is produced, it can damage the battery and reduce its lifespan. One way to reduce the amount of heat generated is to use high voltage. This decreases the current flowing through the battery, which in turn reduces the amount of heat released. In addition, high voltage can improve discharge efficiency and safety. When batteries are charged at high voltages, the reaction proceeds more quickly, allowing for a faster charge. A higher voltage also results in a smaller discharge current, which reduces the risk of fire or explosion. As a result, using high voltage can be an effective way to improve battery performance and safety.
The rise of the voltage platform has led to a decrease in the capacity of single cells. Most energy storage cells on the low-voltage platform are 100Ah, while the high-voltage platform is gradually transitioning to 50Ah. The prismatic cell capacity is 50Ah – 300Ah and the pouch cell capacity is 30Ah – 80Ah.
Longer cycle and higher charge and discharge rate: The cycle of household energy storage cells will be more than 6000 times, and the rate of charge and discharge will be 1C.
The most common batteries on the market are NMC batteries and LiFePO4 (lithium iron phosphate batteries). LiFePO4 is the most commonly used energy storage battery. LiFePO4 has high cycle times, 6000-12000 times; High safety, the temperature of thermal runaway is 270 ℃, higher than 150 ℃ of NMC; The cost is slightly lower than NMC. Therefore, as an energy storage battery, lithium iron phosphate has great advantages and is the mainstream trend of energy storage batteries.
Battery modularization and expandability: The system energy can be expanded through the combination of multiple standard battery modules, which can simplify installation, operation and maintenance, and facilitate the later expansion required by customers due to increased power demand. Users can purchase battery modules directly and install batteries in parallel according to the user manual.
3. What will be the development for energy storage inverters in 2023?
Hybrid inverter (parallel and off-grid integrated inverter): a set of PV+ Energy storage system can be configured with a hybrid inverter. There is no need to install a PV inverter and energy storage inverter respectively on the AC and DC sides to improve the installation efficiency of the optical storage system. The price is about 20% higher than that of the energy storage inverter, and customer acceptance is high.
Higher power inverter: In order to match the increasing power demand of users, the power of household energy storage inverters will also be increased from 3kW and 5kW to 8kW, and it will gradually increase to three-phase 10kW or above. The new products developed by Solis, Growatt, INVT and Sungrow on the market are 10kW, 15kW to 40kW energy storage inverters.
High voltage inverter: The circuit topology of the high-voltage hybrid inverter is simpler, the size is small and the weight is light, and the failure rate is reduced.
Home solar storage is expected to grow exponentially in the next few years, driven by rising energy costs and geopolitical tensions. As the industry expands, there are a few key market trends that you should be aware of. These trends will shape the home solar storage market in 2023 and beyond. So if you’re thinking about entering this rapidly growing industry, make sure you stay up-to-date on these key developments.
