Energy storage is a technology that uses specific devices or physical media to store different forms of energy in different ways for future use when needed. This article will discuss the current use of solar energy storage batteries which is one of the components of solar power system in household, commercial, or industrial settings. Only by understanding the pros and cons of solar battery storage can we better choose whether or not to use them.
The working process of solar battery storage
The basic working principle of energy storage batteries can be divided into two main processes: charging process and discharging process.
When the electricity generated by the photovoltaic system exceeds the electricity demand, the excess electricity will be converted into stable direct current (DC) through a converter and stored in the battery as chemical energy. This process converts electrical energy into chemical energy and stores it in the battery.
When there is insufficient light or at night, the photovoltaic system cannot generate stable electrical energy. The energy storage battery will release the previously stored chemical energy to do work, generating direct current (DC) and converting it into alternating current (AC) through a DC/AC inverter for use in households or businesses. This process converts chemical energy into electrical energy. For now we can see the good side of pros and cons of solar battery storage since it’s a part of the process when we want to store the solar power.

Pros and cons of solar battery storage
The advantages of solar battery storage
Environmental protection and energy conservation
The solar energy storage system utilizes solar energy, a renewable energy source, to generate electricity without producing any pollutants or greenhouse gas emissions, making it very environmentally friendly.
According to statistics, a solar energy storage system installed in an ordinary household can reduce tens of kilograms of carbon dioxide emissions annually, equivalent to planting several large trees. At the same time, the system can significantly reduce electricity costs and achieve energy conservation and emission reduction.
For example, solar energy can be used to generate electricity during the day and stored in batteries for use at night or on rainy days, reducing reliance on traditional power grids and thus saving electricity costs.
Stable and reliable
Solar power generation is not limited by seasons and weather, as long as there is sunlight, it can generate electricity. Although power generation efficiency is affected by environmental factors such as weather and seasons, solar energy storage systems are usually equipped with energy storage batteries that can provide stable power supply when solar energy is insufficient.
Meanwhile, the solar power generation system is also relatively stable and reliable, and will not be affected by external environmental factors. For example, in some natural disasters or power grid failures, solar energy storage systems can serve as independent power sources to provide electricity to households and ensure their normal life.
Independent power supply
Most people have always relied on the State Grid to provide them with electricity services. When the power grid is cut off for a long time, there will be a feeling of helplessness. Home solar energy storage systems can make households more independent and self-sufficient, without relying entirely on the public power grid. Especially in the event of a power outage, energy storage batteries can provide emergency backup power to ensure basic household electricity needs.
Increase property value
Installing household solar energy storage systems can increase the value of a property. Because solar power generation systems are an environmentally friendly and energy-efficient way to increase the attractiveness of real estate.
In some countries and regions, properties equipped with solar energy storage systems are often sold at higher prices. For example, in the United States, properties equipped with solar energy storage systems can increase in value by an average of thousands of dollars.
In addition, research on rooftop photovoltaics has shown that workshops equipped with solar energy systems can reduce temperatures by 4-5 degrees Celsius in summer. In winter, the photovoltaic panels on the roof can also serve as insulation, and compared to outdoors, the indoor temperature can be raised by at least 3-5 degrees. That is to say, photovoltaics can also save a significant portion of air conditioning costs for enterprises. Two pronged approach, enterprise cost cutting is as simple as that.
Reduce electricity costs
By purchasing electricity during low periods and using battery stored electricity during peak periods, households can maximize their savings on electricity bills. In addition, if a grid connected inverter is installed, excess electricity can be sold to the grid for additional revenue.
According to statistics, installing a solar energy storage system in a household can save hundreds or even thousands of yuan in electricity bills each year. Even if you install a distributed photovoltaic power generation system through a loan, which extends your investment payback period, you can still enjoy the visible benefits of solar power generation from the moment your photovoltaic system is connected to the grid.
After the advantages in the pros and cons of solar battery storage part, it’s suggested that installing battery storage as a backup power supply.
The disadvantages of solar battery storage
High cost
The cost of installing a household solar energy storage system is relatively high and requires a certain amount of investment. On the one hand, the installation process requires certain technical and labor costs.
On the other hand, the price of solar battery, solar panel, inverter, and other equipment are relatively high, and energy storage batteries are the most expensive components in photovoltaic systems. Not all photovoltaic systems require batteries, but in the event of a power grid outage, batteries become necessary.
Affected by the environment
The power generation efficiency of solar power generation systems is affected by environmental factors such as weather and seasons, and cannot fully guarantee stable power generation. In rainy weather or at night, solar panels cannot generate electricity and rely on energy storage batteries to provide power. If there is continuous rainy weather or insufficient energy storage battery capacity, it may lead to insufficient household power supply.
Professional installation is required
Installing a household solar energy storage system requires certain technical and professional knowledge. Those who do not understand cannot install it by themselves and require professional installation services. During the installation process, it is necessary to consider issues such as the installation angle, position, and solar panel wiring, as well as the installation of energy storage battery lines to ensure the efficient operation and safe use of the system.
If install solar panel and batteries improperly, it may cause damage to the electrical circuits of the house or pose a safety hazard to the users. For example, when installing solar panels, it is necessary to ensure their firmness and reliability to avoid damage in adverse weather conditions. After looking the disadvantages in the pros and cons of solar battery storage，if you have a limited budget then the solar power system may not be the best choice.
Conclusion
Whether used for off-grid solar power system or on-grid solar systems, solar battery energy storage can help you operate entirely on clean energy. This article mainly discusses Pros and cons of solar battery storage, hoping to help you clarify your purchasing needs.
