During the day or when there is sunlight, solar panels generate solar power. The excess solar energy that is produced can be stored and used during power outages and other emergencies. This is the primary reason why the need for solar energy storage is increasing.
With a solar energy storage system, it is possible to store the excess energy generated by solar panels and use it later to lower electricity bills and reduce dependence on the grid. Scroll down to know more about what is solar energy storage, how it works, the advantages and types of solar energy storage systems, etc.
What Is Solar Energy Storage
What is a battery energy storage system? The battery energy storage system (bess) is a device that is connected to the solar system and stores solar energy. There are various solar energy storage options, such as lithium-ion batteries, lead-acid batteries, flow batteries, saltwater batteries, etc.
In simple terms, solar energy storage is capturing power from the sunlight and converting it to usable electricity that can be stored for later use. How to store solar energy? It is possible to store solar power in different ways, such as using batteries, mechanical storage, and thermal storage options.
How is solar energy stored? After the solar power is sent into the solar batteries, there will be a chemical reaction between the components of the battery, which allows for the storage of solar energy. When the battery is discharged, this chemical reaction will be reversed, so the solar energy can leave the battery and supply power. Storing solar energy in batteries is relatively efficient and can be used at any time.
The main components in the battery energy storage system include a battery management system (BMS), hybrid inverter, batteries (battery bank), charge controller, system meter, and main DC connect.
Batteries store the excess solar energy for later use. Battery management system monitors and optimizes the performance of a battery pack. Hybrid inverter converts direct current electricity into alternating current electricity. Charge controller regulates the flow of electricity from a charging source. System meter monitors the energy production, consumption, and storage within the system. Main DC connect is the main point for connecting the various DC components of the system. There are different types of solar energy storage systems that are ideal for residential, industrial, and commercial solar power applications.
Advantages of Solar Energy Storage
There are plenty of advantages of solar energy storage, and the major ones are listed below.
- Store Excess Energy: With the help of solar energy storage, you can store the excess solar power that is generated by the solar panels when sunlight is available. This way, you can make sure that the additional solar energy is not going to waste.
- Improved Self-reliance: With solar energy storage, you can become more self-reliant by decreasing your dependence on the power grid. This can be particularly helpful in areas where grid reliability is poor or where there are regular power cuts.
- Emergency Backup Power: Solar energy storage can provide emergency backup power during power outages or when there is no sunlight available to generate solar power. As a result, there will be constant power supply to your home, businesses, and other commercial areas.
- Less Electricity Bills: When you store your own solar energy generated by the solar panels, you can decrease your reliance on grid-generated electricity. This way, it will be easy to save a significant amount of money on your electricity bills, leading to long-term savings.
- Better Grid Stability: Solar energy storage can help to enhance grid stability as it offers extra power that can be utilized to meet power demand during peak hours.
- Environmental Impact: Using solar energy storage can decrease the negative environmental impact of generating electricity from non-renewable sources and decrease the carbon footprint. You can store renewable solar energy and support a sustainable future.
Government Incentives: In order to increase the usage of solar energy, governments are offering numerous tax credits and incentives. You can make use of these incentives when installing solar energy storage systems.
Types of Solar Energy Storage Systems
In the present market, there are different types of solar energy storage systems that are ideal for different solar energy storage applications. The primary types of solar power storage systems are home solar energy storage systems and commercial & industrial solar energy storage systems.
Home Solar Energy Storage System
The home solar energy storage systems are mostly used for residential and small-scale solar energy storage and applications. Lithium-ion batteries, lead-acid batteries, and saltwater batteries are the primary types of home solar energy storage systems.
Lithium-ion batteries are the most well-known type of battery for residential solar storage. These batteries have a longer lifespan and are highly efficient. They are also lighter and smaller in size, making them easier to install and maintain. In addition to that, they have high charge and discharge efficiency and ensure little to no energy loss. However, lithium-ion batteries are relatively expensive.
Lead-acid batteries are the most affordable type of home solar energy storage battery. Because of their reliability and affordability, these batteries are mainly used for off-grid remote solar systems. They are capable of handling deep discharge cycles. However, lead-acid batteries have a shorter lifespan and can be dangerous to the environment if they are not disposed of properly.
Saltwater batteries are a new type of battery energy storage technology gaining more popularity. These batteries are budget-friendly, highly efficient, and have a longer lifespan. They can handle deep discharging as well. As these batteries are recyclable, non-toxic, and environmentally friendly, they are a sustainable choice for home solar energy storage systems.
Commercial & Industrial Solar Energy Storage System
Commercial & industrial solar energy storage systems are mainly utilized for large-scale solar energy storage applications, such as industries, commercial areas, etc. The main components of a commercial & industrial solar energy storage system are a battery pack, battery cell, battery management system, switch module, thermal management system, fire safety system, solar panels, and inverters.
The solar panels will capture sunlight and transform it into electricity. The inverter will transform the direct current electricity that is produced by the solar panels into alternating current electricity that can be utilized to powder businesses. The battery will store the generated electricity that can be used later.
The battery management system will monitor and control the battery, and make sure that it is charging and discharging safely and efficiently.
Power conversion system will attach the battery to the power grid so the battery can be used to power the businesses during power outages.
Commercial energy storage systems can help industries reduce their reliance on expensive grid power. The stored energy in the battery can be used to power the business at any time, so commercial industries can be energy-independent.
These energy storage systems allow businesses to reduce their carbon footprint by decreasing their reliance on fossil fuels. During power outages, commercial energy storage systems work as a backup power source and ensure constant power supply to the business. Commercial & industrial energy storage systems also reduce electricity costs and ensure long-term savings.
