How Does Solar Battery Work

How Does Solar Battery Work - Solar batteries can be of great benefit to your solar power system. This gives you more options for powering your home and helps you store excess electricity that you can use when your solar panels aren't producing enough. If you're looking for an explanation of how does solar battery work, this article explains what a solar battery is, how solar batteries interact with solar power systems, and the overall benefits of using solar battery storage.

How Does Solar Battery Work

They make it possible for you to generate your own energy instead of just using the grid. It is also an economical option to power your home as it uses less energy from the grid, thereby reducing your electricity costs. However, setting up an effective energy system involves more than just installing solar panels.

What is a Solar Battery?

You can use solar batteries to store excess electricity produced by your solar panels in your solar power system. Then, on cloudy days, at night, and during power outages when your solar panels don't produce enough electricity, you can use that stored energy to power your home.

The purpose of a solar battery is to enable you to make the most of solar energy. If you don't have battery storage, any excess solar power you produce is sent to the grid, meaning you're creating electricity without fully using the power previously produced by your panels.

How Do Solar Batteries Work with a Solar Power System

The electricity generated by rooftop solar panels is only the first step in the whole process. Here's a detailed description of what happens in a DC-coupled system:

  • Solar panels capture solar energy, which is then converted into DC electricity.
  • DC electricity after entering the battery gets stored in it.
  • The DC energy then exits the battery and enters an inverter where it is converted to AC energy usable for the home.

The process is slightly different with an AC-coupled system - 

  • Solar panels capture solar energy, which is then convert into DC electricity.
  • The inverter receives the electricity and turns it into usable AC power for the home.
  • The excess power is then convert into DC power which can be store by passing it through another inverter.
  • Battery energy must be convert back to AC power by an inverter before it can be used in the home.

Top Benefits of Solar Battery Storage Systems

It's easy to make sure you get the most out of your solar power system by adding battery backup to the solar panels. One of the main advantages of a home solar battery storage system is as follows:

Energy independence

You can reduce your reliance on your utility by installing solar batteries, especially if you live in an area with frequent power outages. Even when the power goes out for your neighbors, a solar battery will keep your lights on and charge your phone. But when you add batteries to your solar system, your solar panels continue to power your home and charge your batteries.

Quiet backup power

Solar batteries give you backup power in case of a grid outage. Solar batteries do not produce any noise, unlike traditional gas generators, which many people use during extended power outages. You can enjoy reliable instant power without the noise or air pollution associated with a gas-powered generator.

Electric bill savings

Installing solar batteries can reduce your electricity costs. However, the type of net metering your utility offers will determine how much you can save. Net metering allows your utility to credit your electricity bill for any excess solar power you transmit to the grid, to partially offset your future energy expenditures.

Reduce carbon footprint

Once you have installed a solar battery you can use all the net solar power generated by your panels. If that solar power isn't store in batteries, you'll eventually need to get energy from the grid, which is often made from fossil fuels.


If you're considering integrating solar panel energy storage into your solar power system, it's important to understand how does solar batteries work. You can use any excess solar power produced by your solar panel as it acts like an oversized rechargeable battery for your home, giving you more choices on when and how to use solar power see you.
