It comes with an app that allows you to wirelessly control your energy usage patterns, which can be especially beneficial in places where variable electric rates change the price you pay for electricity depending on the time of day. The Tesla Powerwall can easily integrate with any home and has a 10-year warranty. Read our full review of the Enphase IQ Battery. Instead, the IQ Battery works with the IQ System Controller 2 to automatically provide power when the grid goes down. Unlike many other solar batteries, the IQ Battery doesn't require an external transfer switch to facilitate backup power. The Enphase IQ Battery comes in two sizes and is advantageous for people who experience regular power outages. Learn more about available home batteries below: Enphase IQ Battery Overall, the best batteries for your home are options that provide scalability, reliability, and durability. ![]() If you have TOU rates, a battery can lower electric bills by providing an alternative power source when utility electricity rates are high. Some utilities have time-of-use (TOU) electric rates, which vary throughout the day. A battery will add to your upfront cost (on average, a 10-kilowatt solar panel system will cost $20,650 after the federal solar tax credit), but over time it can save you tens of thousands of dollars on your electric bill.Įven without solar, your battery can save you money on your electric bill while increasing your energy independence. Not to mention, you need to store the fuel somewhere in your home.īy comparison, if you install a battery for backup power in your home, you can pair it with a solar energy system to charge it with renewable energy from the sun. Fuel costs can add up if you frequently rely on your generator – especially if you must also pay for fuel delivery to your home or business. If you install a generator, you must buy fuel to keep it running. The upfront price you pay isn't the only cost to consider. $29,500 (solar panels) - $8,850 (solar tax credit) + $15,000 (batteries) - $4,500 (battery tax credit) Total cost over 20 years: solar + storage vs. The average net upfront cost of a solar-plus-storage system is around $31,150, based on the following calculation: If you use more energy than your neighbors, you'll need to buy a bigger generator or more batteries, and you can expect the installation cost to add thousands more to your total price tag. Altogether, you can expect to pay anywhere from $10,000 to $20,000 to install a battery backup system depending on your energy needs. Many standby generator options in the $2,000 to $7,000 range can power a standard American home, but the average generator cost, including installation, is $9,000.īy comparison, a 10 kilowatt-hour (kWh) home backup battery will start at around $13,000, and in many cases, you'll require multiple batteries to provide whole-home power. The amount you'll pay to get backup power at your home or business depends on the power you need and your chosen equipment. Finally, there are no local emission concerns with solar & storage installations – they run entirely on clean, renewable solar power. Also, batteries are eligible for incentives like tax credits and rebates, which can significantly lower those upfront costs. When you pair batteries with solar panels, the sun powers them, keeping them charged as long as the sun keeps shining. On the other hand, batteries are more expensive upfront and require an electrician to install, but they solve most of the issues that can sometimes plague backup generators. Finally, and perhaps most importantly, backup generators cause significant local pollution by burning fossil fuels, not the least of which is carbon monoxide, which has become a considerable safety risk with fossil fuel-powered backup generators. Next, backup generators are large, loud machines that shouldn't run every day and require regular maintenance, meaning you only benefit from having them in the event of an outage. ![]() For one, you'll have to ensure you have the fossil fuel they require, which can be problematic during unexpected outages. However, backup generators come with several downsides. ![]() You can frequently buy backup generators at home improvement stores, and some might not even need to be installed by an electrician. Second, in the past, generators have been easy to find and set up at your home. There are two primary reasons that homeowners have historically opted for generators as a backup solution.
