So, how is Solar Energy Stored? Let’s understand, shall we! Solar batteries are an excellent way to store solar energy in the home. Lithium-ion batteries are the most popular form of battery used for solar energy storage. Other solar energy storage technologies on the market, such as lead-acid batteries, last longer, require less maintenance and take up less space than lithium-ion batteries.
Lithium-ion batteries are able to store solar energy through a series of chemical reactions, where lithium ions are moved through an electrolyte solution within the battery. So, when solar panels send electricity to the battery storage system a chemical reaction occurs that moves lithium ions and releases electrons in an electrolyte solution within the battery, which stores the energy.
When you need to use the battery’s electricity, the electrons travel backwards and the battery’s electricity is discharged. This procedure can be done indefinitely, making the battery rechargeable.
The benefits of solar energy storage
Solar energy storage systems are becoming more popular every year and it’s no surprise why – here are just a few of the benefits of installing solar-plus-storage:
Contrary to popular belief, solar panels will not power your home during a power outage. To keep your lights on when the power goes out, you must couple your solar system with a solar battery. Solar batteries are also a far quieter backup power source than gas-guzzling generators. Plus, you don’t have to worry about battery recharging; simply let your solar panels do their thing, and the energy is available for you to utilise!
You are less reliant on the electric grid if you have solar energy storage. We already know that this means you’ll be safe if the electricity goes out on the grid, but it also means you’ll be less reliant on the utility in general.
For starters, solar energy storage shields you against the annual rate rises that are almost unavoidable. A battery allows you to draw electricity from it instead of using the grid and paying high rates. You also know where your power is coming from. You can generate energy by a utility using foreign gas and oil. Now you can happily power your home with the solar energy generated directly on your roof.
Electric bill savings
Because of a utility pricing structure known as net metering, a solar battery won’t save you money on your electricity bill in many regions. Your utility will pay you the full retail rate of power for any excess solar energy that your home does not consume if you have full retail net metering. You might think of the utility as your “financial battery.”
Not all utilities, however, provide complete retail net metering; instead, they purchase excess solar electricity at a lesser cost. This is where solar energy storage can help you save money on your power bills. Rather than transferring your excess electricity to the grid and receiving a low cost, you hold it and receive the full retail value.
If your utility uses Time-of-Use rates to charge higher power bills during peak demand hours, solar storage can help. During these peak hours, you can use the electricity stored in your battery to avoid paying your utility’s high prices. Isn’t it cool to know how much you save when you know how solar energy is stored!
