Saving money, being self-sufficient, even helping out the environment \u2014 it almost seems like the whole thing is nothing but upsides. But not so fast.\u00a0<\/p>\n<p>You may have heard someone say that solar panels degrade \u2014 that even though solar panel manufacturing has come a long way in the last 20 years, they still haven\u2019t worked out the kinks, specifically with regard to the lifespan of solar. And even if you purchase the best solar cells available, they\u2019re not going to last for a long time.<\/p>\n<p>So, is this true? Is the reality of investing in solar panel systems <em>not <\/em>the rosy and benefit-filled experience that the solar panel manufacturers lead us to believe? In a word, no. Those are just rumors. The reality is switching to solar panels does offer significant benefits and every quality installer will offer a warranty, some as long as 25 years!\u00a0<\/p>\n<p>Here we\u2019ll look at the reality of the lifespan for solar panels and what you can expect, whether you\u2019ve already made the switch and are wondering about the longevity of your system, or you\u2019re thinking about taking the plunge.\u00a0<\/p>\n<h2 class=\"wp-block-heading\">How Long Do Solar Panels Typically Last?\u00a0<\/h2>\n<p>If you\u2019re worried you\u2019re going to have to buy all-new solar panels every five years, don\u2019t. The industry standard for most retail photovoltaic (solar) systems is 25 to 30 years. This is significantly longer than standard EPBT times \u2014 energy payback time, the period of time it takes for the panel to produce more energy than was required to produce it. It\u2019s also quite long on its own when compared to the lifespan you can expect from other home appliances, such as 10 to 18 years for a refrigerator or 15 to 25 years for your HVAC.\u00a0<\/p>\n<p>And even after that 25 to 30 year period, it\u2019s not like they completely stop generating electricity, they just begin to lose efficiency. In 2012, the National Renewable Energy Laboratory (NREL) <a href=\"https:\/\/www.nrel.gov\/docs\/fy12osti\/51664.pdf\" rel=\"nofollow noopener\" target=\"_blank\">found<\/a> that the average solar panel output declined by 0.8 percent a year. This \u201csolar panel degradation rate\u201d varies from one manufacturer to the next, with some coming in as low as 0.3 percent. Additionally, that\u2019s a nine-year-old assessment, and more efficient technologies have been developed in the time since.<\/p>\n<h3 class=\"wp-block-heading\">Do Other Components of the System Require Replacement?<\/h3>\n<p>The solar panels themselves are not the only part of the system that has a lifespan. Both the inverter and battery have lifespans that need to be considered. Although the inverter is relatively maintenance-free, replacement every ten to twelve years is the norm. Batteries don\u2019t require much maintenance either, maybe an annual (or less) check from a service tech, and should last up to fifteen years.<\/p>\n<h2 class=\"wp-block-heading\">Why Do Solar Panels Expire?<\/h2>\n<p>One of the appealing things about generating your own electricity from solar panels is that, as long as you keep them free of debris (which can be a large or small effort, depending on the environment), they <a href=\"https:\/\/chariotenergy.com\/chariot-university\/solar-panel-cleaning-maintenance\/\">don\u2019t require much maintenance<\/a>. There are no moving parts; no engine that needs serving, no fluids to be changed out. So when it\u2019s suggested that they can have an expiration date or degrade over time, it\u2019s reasonable to wonder exactly what\u2019s degrading?<\/p>\n<p>Well, while solar panels don\u2019t have any moving pieces, they are made of glass, aluminum, silicon, and other materials. As durable as those materials are, storms, precipitation, and extreme temperatures can cause stress on the materials and cause their efficiency to degrade over time. One of the most common effects of age is \u201cmicrocracks\u201d in the silicon itself that affect the efficiency of <a href=\"https:\/\/chariotenergy.com\/chariot-university\/how-do-solar-panels-work\/\">electricity generation<\/a> and transmission.<\/p>\n<h2 class=\"wp-block-heading\">3 Tips for Making Your Solar Panels Last Longer<\/h2>\n<figure class=\"wp-block-image size-full\"><img alt=\"\" class=\"wp-image-4428\" decoding=\"async\" height=\"1000\" src=\"https:\/\/chariotenergy.com\/wp-content\/uploads\/2025\/12\/solar-panel-cleaning-1.jpg\" width=\"1500\" title=\"\"><\/figure>\n<p>Solar panels might not last forever, but, with a little maintenance, they can produce energy for your home for decades. Here are just a few tips for protecting and getting the most out of your investment.<\/p>\n<h3 class=\"wp-block-heading\">1. Keep \u2018Em Clean<\/h3>\n<p>Your panels won\u2019t ask much of you, just that you keep them clean and free of debris. Leaves, sticks, bird droppings, and anything else that, quite literally, falls from the sky and lands on them will affect performance. Make spraying them off with the hose or sweeping them a regular chore, or have your yard or window cleaner add it to their services.<\/p>\n<h3 class=\"wp-block-heading\">2. Monitor Them<\/h3>\n<p>Keeping an eye on your system and how it\u2019s operating is a basic task nearly everyone does in the background, and you want to do it, too. The vast majority of the time, it\u2019s going to be smooth sailing. No spikes, no hiccups, nothing abnormal. But, if you <em>do<\/em> see some sort of change in your performance or your system status monitor indicates an issue, get it checked out.<\/p>\n<h3 class=\"wp-block-heading\">3. Get a Quality Installer<\/h3>\n<p>You\u2019ve heard it before \u2014 an ounce of prevention is worth a pound of cure. Invest in the best quality system you can afford, and have it installed by a reputable company that is known in your area as the quality source. You don\u2019t want to kick off the start of a quarter-century-long system with substandard equipment or a faulty installation that\u2019s just problems waiting to happen.<\/p>\n<h2 class=\"wp-block-heading\">How Much Does it Cost to Maintain Your Solar Panels<\/h2>\n<p>The maintenance costs for solar panel systems are low. Warranties cover most of the issues if there are any. If you opt for a routine, yearly inspection, the national average is around $150. It\u2019s best to follow the manufacturer\u2019s instructions, but if you only opt to clean them and hire a professional to do the work, average costs are $12 to $20 per panel (most homes have between 15 and 35 panels).<\/p>\n<h2 class=\"wp-block-heading\">What Happens to Your Solar Panels When You\u2019re Done With Them?<\/h2>\n<p>One of the reasons why it\u2019s important to get the most out of your solar panel investment is because, at present, solar panels are <a href=\"https:\/\/chariotenergy.com\/chariot-university\/is-solar-energy-renewable\/\">difficult to recycle<\/a>. The materials they\u2019re made with and the nature of the construction requires a high degree of \u201cdemanufacturing\u201d before the raw components are reusable. This is one of the fastest-moving aspects of the industry and where the next waves of progress will happen.<\/p>\n<h2 class=\"wp-block-heading\">Get Ready for Solar from Chariot<\/h2>\n<p>The U.S. installed 5 gigawatts (GWdc) of solar capacity in the first quarter of 2021 and solar accounted for 58% of all new electricity-generating capacity. If those modest trends continue, over 160 GW of capacity will be installed over the next five years.[1] If you\u2019ve been thinking about solar, keep your eyes on Chariot, as we\u2019re rolling out solar panel system installation in the coming months.
