Best Home Battery Storage Systems in 2022

Let’s start off with answering the question, “what is home battery storage backup?”. The solar industry has grown a lot over the years and shows no sign of stopping. Just as solar installation has seen massive growth, we are now seeing the rise of home battery storage systems. More people nowadays want to live independently from the grid, which is the biggest reason customers look to install battery storage systems. Having to depend on the grid for power can be hard, because it isn’t always reliable. Particularly, in recent years with wildfire season causing power outages across the state. Solar panels can help decrease your energy bill, but they don’t store excess energy unless you add battery backup. Adding home battery storage can go a long way to save you money and energy security. 

The Benefits of Home Battery Storage

There are several benefits to solar + battery storage in today’s market. Solar plus storage is the perfect combination with renewable energy and battery storage to backup the energy coming in from the panels. With this perfect combination you are able to live more independently which offers economic and environmental benefits.

With battery storage, you can make the most of your energy in these 4 ways:

  • Reliability During Power Outages
  • Avoid Utility Consumption During Peak Rate Hours
  • Added Energy Savings
  • Reduced Carbon Footprint

Solar battery backup helps you save more money by allowing you to draw from stored power during times where you are not able to produce as much solar power i.e. rainy days or at night. Installing a home battery can also help make your home more reliable.If you live in an area that occasionally becomes unstable, you can rely on your battery to power your home even if the grid is down. Another benefit of a battery is that it can reduce your carbon footprint. This is great for people that want to go green and reduce pollution. Lastly, and more importantly— in addition to solar power, energy storage systems will help you save on electricity costs. To help you understand how batteries work for you look at the image below: 

How Much Battery Storage Do I Need for My Home?

Is it easy to determine how many batteries you need for your home? It all depends on the situation. Knowing how many batteries you need for your home depends on which of the benefits of battery backup interest you the most. Customers want a home battery to save money, be resilient, or be self-sufficient. Taking these into consideration will determine how many batteries you need for your home.

3 significant factors that can affect how many batteries you should get include:

1. The Electricity Loads You Need Powered  Electricity load is anything that consumes electricity in your home. Knowing how much electricity you need to provide your appliances is very important. This will let you know what needs to be powered and if you’ll need more or less storage capacity. Because the amount of battery storage you need for your home is based on your energy usage.

2. The Solar System’s Size/Production Ability – Next, you need to charge up your battery with electricity. You either pull it from the grid or charge it with your solar system. So it’s essential to know how much solar energy your panels produce and how much you’ll need to charge your battery system during the day. In case you need more storage capacity than your panels can fill. 

3. Are you More Concerned with Cost Savings or Convenience? – And lastly, just knowing what you want to get out of your battery system is vital in deciding how many batteries you need. 

What Are the Best Home Battery Storage Options?

Now, let’s take a look at the best home battery storage systems. Choosing the correct battery for your home is essential. There are a number of factors that come into play when choosing the best battery storage. From the size of your home to the characteristics of your solar installation.

How Much Does a Home Battery Backup Cost?

Solar battery pricing varies depending on battery model and brand. It’s common for an average-sized home battery backup system to cost between $500 and $20,000. How many batteries do you need to power your home and the installation cost.

Can I Have a Home Battery Storage Without Solar?

Yes, you can have a home battery storage system without solar panels. However, not many homeowners know that you can have batteries that will be charged from the power supplied by the grid to store in case of a power outage. Even without solar panels, homeowners can save money with just a battery because energy is time-dependent. Using the battery when utility companies charge a premium can save you money and help you reduce energy costs.  

How Long Do Home Battery Banks Last?

Most solar batteries last between 5 to 15 years. While the battery life is long, a replacement will be needed, especially if not you’re not providing care to your battery. It’s essential to know, like solar panels, that the quality of the battery and how well it is maintained plays a part in it. Ensuring you provide proper system maintenance will ensure maximum life expectancy.
