Your Guide to Home Backup Batteries in | EnergySage

When you picture a battery, the first thing to come to mind is probably the disposable batteries you put in everyday appliances like your TV remote. But did you know you can power your entire house with (much larger) batteries?

You don't need a home solar panel system to reap the benefits of home battery backup. But you'll get the most out of your system when you pair them together—especially if your utility doesn't pay you much for the excess electricity your solar panels generate and send to the grid. 

We explain how to decide if backup batteries are right for you and, if so, how to get a battery system that fits your needs at the best price.

Home backup batteries store extra energy so you can use it later. When you only have solar panels, any electricity they generate that you don’t use goes to the grid. But with residential battery storage, you can store that extra power to use when your panels aren’t producing enough electricity to meet your demand.

Most batteries have a limit on how much energy you can store in one system, so you may need multiple batteries if you want to have enough capacity for long-duration backup. Also, most batteries can’t store electricity forever—even the best home battery backups will slowly lose charge over time, whether or not you use them.

You don't need solar to install a home battery, but batteries only store energy, they don't produce it. Pairing your battery system with solar panels allows you to truly increase your grid independence and your electric bill savings. Here's how it works: 

But home backup batteries are becoming an increasingly popular choice over home generators. They offer many of the same backup power functions as conventional generators without the need for refueling. While they're more expensive upfront and require an electrician to install, you can "refuel" them for free with the sun's energy if paired with solar panels. They're also much quieter than generators and don't come with emissions-related health concerns.

Most batteries last about 10-15 years, meaning you'll have plenty of time to break even on your investment. While many homeowners can benefit from installing a battery system, they're not right for everyone. Here are a few questions to answer when deciding if you should add a home battery:

Power outages are an occasional nuisance for everyone, but for some people, they're a far too regular occurrence: According to the Energy Information Administration, the average U.S. electricity customer experienced 5.5 hours of electricity interruptions in . However, customers in Florida, West Virginia, Maine, Vermont, and New Hampshire experienced average outages ranging from 10.3 hours in New Hampshire to 19.1 hours in Florida.

Under these policies, you could still have a hefty electric bill even with solar. By pairing your solar panels with a battery, you can program your system to export electricity to the grid only when compensation rates are high and pull from your battery when rates are low, maximizing your savings.

Even if you don't have solar, batteries alone can be worth it if your utility uses a complex electricity rate structure. Time-of-use, or TOU, rates are a form of "time-varying rates" designed to better reflect the actual cost of electricity based on the amount of supply and demand. Utilities have used TOU rates for businesses for many years, but they're becoming an increasingly common way to charge homeowners. Under TOU rates, your electricity cost will vary from hour to hour, day to day, and season to season. With a battery, you can use your stored energy to avoid pulling electricity from the grid when it costs the most. 

Demand charges are also common for businesses and are becoming more common for homeowners. With demand charges, your utility company tracks your maximum energy pull from the grid during any given hour (or even 15-minute period) per month and charges you based on that maximum demand for the whole month. With a battery, you can lower your peak demand from the grid, driving significant bill savings.

If you want to install a home battery but are overwhelmed by the cost, rest assured there are plenty of incentives available that can significantly lower the price. Depending on where you live, you could break even on your home battery storage investment in less than a year. Here are some of the top battery incentives that will either reduce your upfront cost or increase your long-term savings:

In , a 10 kWh battery costs about $7,000 after the federal tax credit based on thousands of quotes through EnergySage.  This price tag is high, but if you've determined that a battery is right for you based on your answers to the questions we outlined so far, it will pay off over time. 

But if you live somewhere with net metering and a flat, non-time varying electricity rate, the only financial savings from installing energy storage come from avoiding outages or receiving any available state incentives. In those instances, you won't see any more bill savings from adding a battery to your solar panel system.

What Is the Right Energy Storage for Your Home? | FranklinWH

As homeowners, it is important to understand the different energy storage solutions available to us. Whether you are looking to reduce your energy usage or become more energy efficient, implementing an energy storage system for your home is one of the best ways to do it.

This post will discuss the various energy storage solutions for residential homes, how they work, and the benefits of investing in an energy storage system for your home.

What Is Energy Storage?

Home energy storage, or residential energy storage, is a way of storing energy from solar, wind, or other power sources when electricity is needed. Energy storage for homes isn't a brand-new concept, but it's becoming more widespread as people look for ways to downsize their carbon footprint and save money on their electricity bills.

Some Types of Home Energy Storage Systems

Batteries: The ability of very big batteries to store electricity until required is not dissimilar to that of more typical rechargeable batteries. These systems can use various battery technologies, including lithium iron, lithium-ion, lead acid, and others.

The storing of thermal energy: It is possible to generate thermal energy with the help of electricity, and this energy can be saved for later use. For instance, during periods of low electricity demand, it is possible to use power to make chilled water or ice, which can be used for cooling during courses of high electricity demand.

Flywheels: Flywheels, which are a type of rotor, can be accelerated with the use of electricity, which then allows the energy to be preserved in the form of kinetic rotational energy. When it is necessary to produce energy, the force created by the flywheel's rotation is applied to turn a generator. Some flywheels use magnetic bearings, can achieve rotating rates of up to 60,000 revolutions per minute, and operate in a vacuum to limit the drag they experience.
