What is residential energy storage and how does it work?

increase the amount of self-produced energy you consume instead of consuming it from the energy grid. This is called protected from price spikes, supply fluctuations and blackouts. If one of your main reasons for installing solar panels is to reduce carbon emissions, adding a battery to your system helps you get the maximum performance in terms of reducing your greenhouse gas emissions and your home&#;s carbon footprint. Home energy storage systems are also cost-effective, since you will be storing  power from a source of clean, renewable energy that is completely free: the sun.

Thanks to the home energy storage battery, you canyou consume instead of consuming it from the energy grid. This is called self-consumption , meaning the capability of homes or businesses to generate their own power, and is an important concept in today&#;s energy transition . One of the advantages of self-consumption is that customers use the power grid only when they are not using their own self-generated power, allowing them to save on costs and avoid the risk of power outages. Energy independence from self-consumption or going off the grid means you are not reliant on a utility for your energy needs, and are therefore. If one of your main reasons for installing solar panels is to, adding a battery to your system helps you get the maximum performance in terms of reducing your greenhouse gas emissions and your home&#;s carbon footprint. Home energy storage systems are also cost-effective, since you will be storing power from a source of clean, renewable energy that is completely free: the sun.

This article is the second in a two-part series on home batteries. In case you missed it, here&#;s part 1: &#;&#;Is adding a battery to your rooftop solar worth it? Here&#;s how to decide.&#;

Alex Bazhinov has turned his home into a clean energy power plant, complete with the ability to store renewable energy for when he needs it. The solar panels on his roof in Charlottesville, Virginia, feed his home battery during the day, so it can charge his electric vehicle in the evening. This allows him to avoid the cost of charging from the grid; plus, he said, &#;&#;I know that I&#;m driving on truly clean electricity.&#;

Besides their ability to deliver renewable power, home batteries can provide resilience in the face of outages and deliver a quicker system payback than installing rooftop solar alone. And while home batteries are still expensive, for the first time, their costs are coming down, Charles Hadlow, president and chief operating officer at clean energy marketplace EnergySage, told Canary Media. 

Based on over 300,000 EnergySage battery system installation quotes done through the platform, costs tumbled from the first half of to the second half from a median of $1,352 per kilowatt-hour (kWh) stored to a median of $1,265.

Thanks to these falling costs, a changing policy landscape, and a bevy of incentives, batteries are becoming a hot home addition. In , the number of solar customers also installing home batteries hovered below 10% nationwide. Now that rate has shot to more than 30% &#; in large part because Californians are flocking to batteries amid a new regulatory regime that incentivizes them. Texas and Florida are also moving the market, potentially driven by extreme weather, Hadlow said.

If you already have rooftop solar &#; or are planning to get it &#; and you&#;re intrigued by a home battery&#;s benefits, you&#;ll have a number of factors to consider first. Buying a battery is like buying a car &#; only, how to evaluate batteries is less familiar.

So here are seven key questions to ask yourself before you get a home battery of your own.

1

. How much stored energy, or capacity, do I need?

Batteries have two major features: their capacity (how much energy they can store) and their power rating (how fast they can deliver that stored energy). Think of the battery&#;s capacity like a tank of water; the power rating is like the size of the pipe that drains it.

An average home uses 29 kWh per day, and a typical battery stores 10 to 13 kWh. To determine how many batteries will cover your needs, a good contractor will use software to analyze your energy consumption data from your utility, said Barry Cinnamon, CEO of California-based Cinnamon Energy Systems. The system size will also be influenced by how you answer this next question.

. What appliances do I want to back up? 

Different appliances have distinct power requirements. A Wi-Fi router takes less power to run than a refrigerator, which takes less power than an air conditioner or a sump pump. Appliances also have different needs for peak or surge power (like when an AC kicks on) and for continuous power (to keep the AC running over time). If the devices you plan to back up are power hungry, you&#;ll want to make sure your battery is rated to provide for their peak and continuous power needs.

These power ratings &#;&#;are changing pretty fast,&#; Hadlow said. &#;&#;Some of the latest batteries coming out, such as the PowerWall 3, Franklin Whole Home [aPower], and Enphase IQ 5P, are significant improvements over what we&#;ve seen in the past.&#;
