Solar photovoltaic systems have become a popular option for household energy investment due to the support of net electricity settlement policies. Installing photovoltaic panels is not only environmentally friendly, but also typically can recoup costs within six to eight years. However, as this policy is set to be completely abolished by 2027, people are starting to rethink the value and investment logic of solar energy systems.
Does this mean that solar energy is no longer worth investing in? In this article, solar energy battery storage as a critical component of solar energy storage systems will be mainly discussed from its definition, the working process, household energy storage application and some relevant aspects to the best sale solar energy battery storage in Tycorun for you to choose for your solar energy storage systems.
What is solar energy battery storage
Taking a household solar power generation system as an example, it captures sunlight through solar panels installed on the roof. The electric field converts direct current into alternating current through the PV inverter in the house, and the the solar energy battery storage unit preserves surplus electricity for later use.
How does solar energy battery storage work
The solar energy battery storage process is actually divided into three steps - being able to store, being able to manage steadily, and being able to release. Just like storing water in a reservoir which means charging is like storing water by closing the gate, discharging is releasing water by opening the gate, and the control system is the engineer who precisely adjusts the water valve.
When the photovoltaic panels generate electricity crazily, the solar energy battery storage systems a stock up mode. Direct current is directly injected into the battery, and the lithium ions inside the battery move from the positive pole to the negative pole. The battery management system (BMS) monitors the temperature and voltage throughout the process, just like equipping each battery compartment with an intelligent manager.
When electricity is needed, the system instantly switches to release mode. Lithium ions are collectively withdrawn from the negative electrode to the positive electrode, and the inverter translates DC electricity into AC electricity that can be understood by household energy. The energy management system (EMS) intelligently schedules and prioritizes the protection of critical loads such as refrigerators and routers.
Why can't charging and discharging be carried out simultaneously?
This limitation is inherent in all solar energy battery storage designs. But the explain is also reasonable. This is like a person who cannot eat and vomit at the same time. The system divides the charging and discharging periods through a power converter (PCS) to avoid energy reflux conflicts. At the same time, the BMS ensures orderly migration of lithium ions, similar to traffic lights regulating traffic flow. Strictly divide the charging/discharging time periods to prevent energy from competing with each other. Remember this essence: charging and discharging is the collective migration of lithium ions, and the control system is their traffic police.
Solar energy battery storage for home
If you want to install an energy storage system for your home, would you choose a completely independent off-grid model or a grid connected model that can be integrated with the power grid?
Home off-grid system
Solar energy battery storage in off-grid system, are suitable for pastoral areas, fishing boats, and deep mountain homestays without grid coverage.
Off-grid essential large capacity batteryand diesel generator backup
The outstanding advantage is 100% energy independence, completely eliminating the anxiety of power outages
Fatal weakness
The initial cost is 30% higher, the lifespan of lithium iron phosphate batteries can reach 10-15 years, and lead-acid batteries need to be replaced after 3-5 years. If the demand for electricity increases, further expansion is needed.
Household grid connected system
Grid-tied solar energy battery storage systems allow households or commercial business that have a power grid but want to save money
The core advantage is to earn subsidies by connecting surplus electricity to the grid, and to store electricity when electricity prices are low
Cost saving tip
When the price difference between peak and valley is greater than 0.7 yuan/kWh, the annual income exceeds the equipment price by 30%. Taking the 5kW off-grid system as an example, the total investment is 45000 to 70000 yuan. Combined with the peak and valley electricity price difference and policy subsidies, the investment return rate in some areas can reach 11% -25%.
Potential risks
Dependent on policy changes, restricted during power grid maintenance.
When choosing household solar energy battery storage, check the stability of the power grid and choose off-grid when there are frequent power outages. Secondly, consider the volatility of electricity prices, that is, the peak valley price difference for grid connection. Pay attention to policy subsidies, and in areas with subsidies, close your eyes and connect to the grid. Look at the electricity demand four times. off-grid is a necessity for survival, while grid connected is a financial tool!
Is it worth getting battery storage with solar panels
We have installed solar panels at home, but when it comes to wind, rain, and continuous rain, we have to rely on the regular power grid instead. In the blink of an eye, the summer is long and scorching, but there is no way to use the excess electricity, and we can only watch helplessly as electricity is wasted.
If you often have such confusion, then it may not be a good choice to install the panel together with solar energy battery storage. Combining solar panels with solar energy storage batteries can not only reduce monthly electricity bills, but also avoid energy waste and reduce greenhouse gas emissions, which is the development direction of modern green homes.
Reduce electricity bills
Modern solar energy battery storage solutions can help you further reduce your electricity bills. Peak shaving and valley filling - store the cheap electricity that floods at noon and avoid the peak electricity consumption of 1 yuan per hour at night. In addition, at night and on cloudy days, energy storage batteries release energy to connect the periods when solar panels cannot work.
Resist power outages
Advanced solar energy battery storage configurations can be emergency backup. The power grid will automatically switch when there is a power outage, and the refrigerator and router at home will not be powered off. When encountering blizzards, storms, or other power outages, energy storage batteries can enable households to be self-sufficient without the power grid. Compared to other diesel generators, solar energy combined with energy storage batteries provides longer power supply time and is more environmentally friendly.
Comprehensive Green
Whether powered directly by solar energy during the day or continuously discharged from energy storage batteries, 100% green energy is guaranteed. Finally, in addition to installing solar panels and batteries at home, there is a simpler way to purchase and use green energy, which is to choose a 100% green solution from a power sales company.
What is the best battery to store energy from solar panels
The answer to this question is Tycorun’s excellent solar storage battery. With High safety and stability lithium iron phosphate battery technology, suitable for long-term use, reduces replacement frequency and maintenance costs.
Equipped with a rated capacity of 200Ah, it can provide 10240Wh of electricity to meet high energy consumption needs and ensure long-term power supply. Tycorun's solar energy storage battery is particularly suitable for household use and small commercial use.
Tycorun's solar energy storage battery supports high voltages such as 51.2V/48V, efficient home energy storage, and enables intelligent energy allocation.
