However, there are still a number of factors that can influence the cost of your battery installation.\r\n<h3>Solar Battery Price Factor 1: Your battery capacity<\/h3>\r\nThe biggest factor that impacts the price of a solar battery is its capacity \u2013 the total amount of energy that it can store. For instance, there are 5 kWh batteries used mostly for improving the economics of solar, and there are 40 kWh battery systems that can back up your entire home during a power outage.\r\n\r\nWhile larger systems come with a higher price tag, you'll likely pay less per kilowatt-hour of storage.\r\n<h3>Solar Battery Price Factor 2: DC vs AC<\/h3>\r\nDC batteries like <a href=\"https:\/\/www.solar.com\/learn\/lg-chem-battery\/\">LG Chem<\/a> tend to be less expensive than AC batteries since they\u2019re less complex to configure (see chart below).\r\n\r\nThe kicker is that DC batteries are difficult to add to existing solar systems and, depending on the solar equipment, a DC battery may not be an option for all systems. On the other hand, AC batteries like the <a href=\"https:\/\/www.solar.com\/learn\/tesla-powerwall\/\">Tesla Powerwall<\/a>\u00a0can be configured into any new and existing solar system with relative ease.\r\n\r\n<img class=\"aligncenter wp-image-11390 size-large\" src=\"https:\/\/assets.solar.com\/wp-content\/uploads\/2023\/09\/AC-VS-DC-COUPLED-BATTERIES-4-1024x628.png\" alt=\"AC VS DC COUPLED BATTERIES\" width=\"1024\" height=\"628\" \/>\r\n<h3>Solar Battery Price Factor 3: Balance of System (BOS) Equipment<\/h3>\r\nInstalling a solar battery is not as simple as sticking a battery to the wall and running a wire to the main electrical panel. There are other important pieces of equipment that are critical to enabling home batteries to provide backup power.\r\n\r\n<strong>The type, scope, and complexity of your balance of system equipment will influence the price of your overall project.<\/strong>\r\n<h4>Backup Gateway<\/h4>\r\nThe backup gateway is a device that detects power outages and isolates the home from the electric grid. In that respect, it\u2019s similar to a transfer switch for a generator. This is a critical component for allowing the solar battery to provide backup power without back-feeding power to the grid.\r\n\r\nIn recent years, Tesla and Enphase have released <a href=\"https:\/\/www.solar.com\/learn\/why-the-tesla-backup-switch-is-a-game-changer-for-home-backup-power\/\" target=\"_blank\" rel=\"noopener\">\"meter collar\" devices<\/a> that replace the backup gateway and lower installation costs.\r\n\r\n[caption id=\"attachment_9271\" align=\"alignnone\" width=\"2048\"]<img class=\"size-full wp-image-9271\" src=\"https:\/\/s3.amazonaws.com\/solarassets\/wp-content\/uploads\/2020\/05\/tesla-powerwall-installation-layout-essential-loads.png\" alt=\"tesla-powerwall-installation-layout-essential-loads\" width=\"2048\" height=\"1052\" \/> <span style=\"font-size: 10pt\"><em>Image courtesy: Tesla<\/em><\/span>[\/caption]\r\n<h4>Critical Loads Panel<\/h4>\r\nMost solar batteries have enough power to back up circuits up to 30amps. Therefore, the majority of battery systems do not back up the entire home, but rather just the circuits that are most important to the homeowner.\r\n\r\nTherefore, <strong>installing a solar battery usually requires the installation of a sub-panel<\/strong>, often referred to as a \u201ccritical loads panel\u201d, that houses the important circuits that will be backed up in an outage.\r\n\r\nWhen the outage occurs, the backup gateway isolates the home from the grid and switches the battery to feed the critical loads panel, rather than the whole main electrical panel. This switchover only takes a fraction of a second - homeowners won\u2019t even see their lights flicker!\r\n\r\n<strong>Related reading: <\/strong><a href=\"https:\/\/www.solar.com\/learn\/how-long-can-a-battery-provide-power-during-an-outage\/\">How Long Can Solar Battery Power a House During an Outage?<\/a>\r\n\r\n<img class=\"aligncenter size-medium\" src=\"https:\/\/assets.solar.com\/wp-content\/uploads\/2023\/09\/Solar-Battery-Backup-Configuration-and-Balance-of-System-Equipment.png\" alt=\"Chart showing solar battery backup configurations and balance of system equipment\" width=\"450\" height=\"273\" \/>\r\n\r\nWhole-home backups are possible with batteries, although doing so will require multiple batteries, as sufficient battery power is required for even the highest-amperage, most energy-intensive applications in the home. As a result, the majority of homeowners opt for a critical loads backup to save the cost of multiple batteries.\r\n<h3>Solar Battery Price Factor 4: Battery installers<\/h3>\r\nAfter spending thousands of dollars on a solar battery, it\u2019s best to make sure that the battery is installed properly, fully permitted, and functioning as intended for its full lifetime.\r\n\r\nIt\u2019s therefore essential to install the battery using a vetted and experienced company that has experience with these systems. Going with a pro might cost a bit more upfront, but it\u2019s totally worth it to avoid time and money to fix mistakes later on.\r\n\r\nIf it\u2019s worth doing, it\u2019s worth doing right!\r\n<h3>Solar Battery Price Factor 5: Incentives<\/h3>\r\nIncentives also have a significant impact on the cost of a solar battery system.\r\n\r\nThe 30% tax credit for purchasing battery storage (with cash or loan) ends on December 31, 2025. However, there is a federal tax credit available through the end of 2027 for\u00a0<em>leasing\u00a0<\/em>battery storage through a third-party owner.\r\n\r\nA couple of local battery incentives include:\r\n<ul>\r\n \t<li><a href=\"https:\/\/www.solar.com\/learn\/sgip-info-battery-storage-rebate-up-to-100-percent\/\">California\u2019s SGIP program<\/a><\/li>\r\n \t<li><a href=\"https:\/\/www.solar.com\/learn\/maryland-tax-credit-for-home-batteries-explained\/\" target=\"_blank\" rel=\"noopener\">Marylands 30% tax credit<\/a><\/li>\r\n \t<li><a href=\"https:\/\/www.solar.com\/learn\/duke-energy-powerpair-solar-and-battery-rebates-in-north-carolina\/\" target=\"_blank\" rel=\"noopener\">Duke Energy's PowerPair rebate in North Carolina<\/a><\/li>\r\n<\/ul>\r\n[pnpZip background=true border=true primary_color=\"#8b72d3\" content_texts=true utm_campaign=\"get_started_injectable\" utm_medium=\"solar battery price\" upper_text= \"Compare quotes from \" upper_text_span = \"vetted battery installers\" lower_text= \"See exactly how much\" lower_text_span = \"batteries cost today\" get_started_text = \"Get started\"]\r\n<h3>Solar Battery Price Factor 6: Financing<\/h3>\r\nJust like a house or car, home batteries can be financed to spread the upfront cost over a long period of time. If you buy solar and battery together, you can <a href=\"https:\/\/www.solar.com\/learn\/solar-loans\/\">finance them together in the same loan<\/a>. There are also financing options available for buying a battery on its own.\r\n\r\nThe upside to financing is that you can access the benefits of solar and\/or battery with no money down, <em>as long as you qualify for the loan.<\/em> The downside is interest payments on the loan accrue over time to increase the overall cost of the system.\r\n\r\nFor example, using the example from earlier, financing a 7.9 kW solar system and 12.5 kWh battery with a 20-year loan (with zero money down) would cost nearly $47,000 while paying cash would cost around $30,000.\r\n\r\n<img class=\"alignnone size-medium\" src=\"https:\/\/assets.solar.com\/wp-content\/uploads\/2023\/09\/solar-and-backup-battery-versus-PGE-Grid.png\" width=\"2270\" height=\"1807\" \/>\r\n\r\nIt\u2019s worth noting that most solar and battery loans allow you to pay off the loan early and you can also make a down payment to lower the monthly principal and interest payments.\r\n<h2><a id=\"worth\"><\/a>Is a Solar Battery Worth the Cost?<\/h2>\r\nWhether solar battery storage is worth the cost in 2026 is totally up to you and your energy goals.\r\n\r\nIf you experience frequent or long-lasting power outages, then having battery storage for backup power can be a game-changer in keeping you safe, productive, and comfortable (not to mention keeping your food from spoiling!).\r\n\r\nBatteries are also used as a cost-savings tool in areas with unfavorable net metering policies, most notably <a href=\"https:\/\/www.solar.com\/learn\/new-nem-3-0-savings-calculations-show-path-to-maximum-bill-reduction\/\" target=\"_blank\" rel=\"noopener\">California\u2019s NEM 3.0 solar billing<\/a>. In this case, the upfront cost of battery storage more than pays for itself by increasing monthly bill savings.\r\n\r\nIf battery storage isn\u2019t in the cards right now, keep a close eye on battery prices going forward! The cost of solar batteries is forecasted to continue falling at a rapid pace as the industry matures and new technologies emerge.\r\n\r\n<span style=\"color: #ffffff\">*<\/span>\r\n\r\n[pnpZip background=true border=true primary_color=\"#8b72d3\" content_texts=true utm_campaign=\"get_started_injectable\" utm_medium=\"solar battery price\" upper_text= \"Compare quotes from \" upper_text_span = \"vetted battery installers\" lower_text= \"See exactly how much\" lower_text_span = \"batteries cost today\" get_started_text = \"Get started\"]\r\n\r\n<span style=\"color: #ffffff\">*<\/span>\r\n<h2><a id=\"why\"><\/a>Why are solar batteries so expensive?<\/h2>\r\nThere are a handful of factors that influence the price of solar batteries, but perhaps the greatest reason they are expensive is simply because <strong>residential-scale batteries are a newer technology, and new technologies tend to be expensive at first before rapidly falling in price as the market matures.<\/strong>\r\n\r\nFor example, a 60-inch 4K TV cost <a href=\"https:\/\/www.statista.com\/statistics\/461162\/average-selling-price-of-4k-tv-worldwide\/\"><em>around $9,000 in 2012.<\/em><\/a> Today, you can walk into Target and buy a 65-inch 4K TV for under $400.\r\n\r\nLithium-ion batteries are on a similar trajectory, with the cost per kWh of individual battery cells falling 97% from 1991 to 2018.\r\n\r\n<img class=\"aligncenter size-medium\" src=\"https:\/\/assets.solar.com\/wp-content\/uploads\/2023\/09\/Battery-cost-decline.png\" alt=\"Cost per kWh of lithium battery cells from 1991 to 2018\" width=\"1363\" height=\"1267\" \/>\r\n\r\nIt\u2019s also important to put the cost of solar batteries into perspective. Sure, $27,000 for a solar and battery system sounds like a lot of money \u2013 and it is \u2013 <em>but it\u2019s far less expensive than paying for grid electricity over time<\/em>.\r\n<h3>The cost of solar &amp; battery versus grid electricity<\/h3>\r\nTake the largest utility in the US \u2013 Pacific Gas &amp; Electric (PG&amp;E) \u2013 which serves over 5 million households in California and regularly makes headlines for its <a href=\"https:\/\/www.npr.org\/2019\/10\/27\/773753138\/nearly-1-million-customers-to-lose-power-in-planned-pg-e-power-outages\" target=\"_blank\" rel=\"noopener\">planned<\/a> and <a href=\"https:\/\/www.kron4.com\/weather\/san-jose-mayor-blasts-pge-for-heat-wave-power-outages\/\" target=\"_blank\" rel=\"noopener\">unplanned grid outages<\/a>.\r\n\r\nPG&amp;E customers currently pay <a href=\"https:\/\/www.solar.com\/learn\/pge-electric-rates\/\" target=\"_blank\" rel=\"noopener\">38 cents per kWh<\/a> on average for electricity. If that price rises at a <em>conservative <\/em>rate of 3% per year, the average customer would pay nearly $92,000 for electricity over 20 years.\r\n\r\n<img class=\"aligncenter size-medium\" src=\"https:\/\/assets.solar.com\/wp-content\/uploads\/2023\/09\/solar-and-backup-battery-versus-PGE-Grid.png\" alt=\"chart depicting the cost of solar and backup battery versus grid electricity from PG&amp;E\" width=\"2270\" height=\"1807\" \/>\r\n\r\nSuddenly, home solar and battery storage don\u2019t seem so expensive\u2026 And that\u2019s not to mention the time, money, and comfort saved by having backup power during grid outages.\r\n<h2><a id=\"FAQ\"><\/a>Frequently asked questions<\/h2>\r\n<h3>What is the average cost of a solar panel battery?<\/h3>\r\nA fully-installed 13.5 kWh solar battery costs $13,500 on average, after claiming the 30% tax credit. This price can vary from project to project as there are many factors that influence battery storage costs.\r\n\r\n<em>Update:\u00a0The homeowner-claimed tax credit for home battery storage is only available until the end of 2025. Systems need to be\u00a0<\/em><strong><em>installed<\/em><\/strong>\u00a0<em>by December 31, 2025 to qualify for this credit before it is gone.<\/em>\r\n<h3>How long will a 10kW battery last?<\/h3>\r\nMost 10 kW solar batteries have warranties that guarantee 70% usable capacity after 10-12 years or a certain number of charge\/discharge cycles. It\u2019s worth noting that manufacturer warranties are typically quite conservative and the solar and battery equipment currently in deployment is far outperforming their warranties.\r\n\r\nWe simply won\u2019t know exactly how long today\u2019s batteries will last until they reach their useful end-of-life decades from now.\r\n<h3>Is it worth adding a battery with solar panels?<\/h3>\r\nAdding battery storage to a solar system is particularly worthwhile for homeowners who:\r\n<ul>\r\n \t<li>Experience frequent and\/or long-lasting grid outages<\/li>\r\n \t<li>Have critical systems (medical devices, water pumps, etc.) that run on electricity<\/li>\r\n \t<li>Want to store and use their own clean solar production, rather than pulling dirty electricity from the grid<\/li>\r\n \t<li>Have time-of-use rates and\/or unfavorable net metering compensation<\/li>\r\n \t<li>Desire energy independence<\/li>\r\n \t<li>Want to contribute to a more resilient power grid and\/or be ready to participate in Virtual Power Plant (VPP) arrangements<\/li>\r\n<\/ul>\r\nThere are many reasons to add battery storage to a solar system \u2013 whether it\u2019s worth it or not is up to you!\r\n\r\n<a href=\"https:\/\/www.solar.com\/dashboard\" target=\"_blank\" rel=\"noopener\">Connect with a solar.com Energy Advisor to compare live battery pricing from our vetted network of installers.<\/a>","link":"https:\/\/www.solar.com\/learn\/solar-battery-price\/","name":"Solar Battery Prices: Is It Worth Buying a Battery in 2026?","slug":"solar-battery-price","taxonomy":"category","parent":45,"meta":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v19.5 (Yoast SEO v19.10) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Solar Battery Prices: Is It Worth Buying a Battery in 2026? | Solar.com<\/title>\n<meta name=\"description\" content=\"Solar batteries bring a lot of significant value to a solar system.
