Solar 101: How Long Do Solar Panels Last

How long do solar panels last? This is something that we get asked all the time. Most people know how long their car and household appliances will last but solar panels are still fairly new to incorporate into your home. Recently, one of our solar consultants was at a customer’s home to size them for an updated system. To his surprise, when he arrived, he saw solar panels that he had installed for them in 1976 and they were still producing power 42 years later! While the technology has gotten even better since then it is safe to say that solar panels will last you a long time.
"Photovoltaic Degradation Rates - An Analytical Review"
In 2012, the National Renewable Energy Laboratory (NREL) published a study called “Photovoltaic Degradation Rates – An Analytical Review” after testing nearly 2,000 solar installations. The study found that for traditional silicon-based solar panels, the median reduction in efficiency is about 0.5% per year. Which means that even after a 25-year “productive lifespan”, solar panels can still operate at around 88% efficiency on average.

Based on this study we can conclude that solar panels will keep producing for well over 25-30 years. Those that power the International Space Station are depended on by astronauts for over 13 years. Even more impressive are the solar panels that are used for communications and exploration satellites. These panels have been operating for over 60 years!

In the years since the 2012 study, new technology has been developed to produce more efficient panels. The lifespan of solar panels, which is already impressive, can only continue to increase. That being said the panels available today, produce energy for decades and come with warranties to keep your mind at ease.
Warranties
At Apex Solar Power we offer the Best-In-Class Warranties. These include a 25-year Workmanship Warranty and a 10-year Production Guarantee for every system installed on top of the 25-year Equipment Warranty. With these warranties you can sit back and enjoy the benefits of the sun once your system is installed.
Do you have questions about the lifespan of solar panels or the warranties available to you? Reach out to us here and we would be happy to answer any of your questions! If you are ready to make the switch to solar you can get a free quote here!

What the 2026 Utility Rate Changes Mean for Homeowners As we move into 2026, homeowners are facing a major shift in how much it costs to power their homes. Utilities across the country are preparing for another round of significant rate increases — driven by aging infrastructure, higher demand, and rising energy costs. At the same time, the federal solar tax credit is set to step down, reducing the incentive homeowners have relied on for years. While this combination may sound discouraging at first, it actually underscores a larger truth: with utility rates climbing faster than ever, going solar still makes long-term financial sense. Rising Utility Rates in 2026 Many utility providers have already announced increases for 2026, and the trend is consistent nationwide. In fact, the New York Public Service Commission (NYPSC) has approved an increase of 30% increase for New York utilities to occur over the next 3 years. Electricity costs are going up, fixed monthly charges are increasing, and more utilities are shifting to time-of-use pricing models that penalize homeowners during late-afternoon and evening peaks. In some regions, residential demand charges — once reserved for commercial customers — are becoming more common. For the average homeowner, this translates to noticeably higher bills even if their usage stays the same. Some areas could see annual increases of 10–25% as these new structures take hold. The Solar Tax Credit Is Decreasing — But the Savings Aren’t 2026 is also the year the federal solar Investment Tax Credit steps down from the full 30% for many homeowners. This means installing solar will carry a slightly higher upfront out-of-pocket cost than in recent years. However, the long-term economics still strongly favor solar. While the tax credit reduces, electricity prices continue to rise every year — and those increases compound over time. The value of producing your own electricity becomes greater with each rate hike, often offsetting the reduced tax incentive within just a few years. In other words, the short-term increase in system cost is still outweighed by decades of escalating utility prices. Why Solar Still Makes Financial Sense Solar’s value has always come from its ability to provide clean, predictable, stable energy for decades — and that hasn’t changed. What has changed is how quickly grid-supplied electricity is becoming more expensive. By installing solar, homeowners reduce or eliminate their reliance on a system where prices are uncontrollable and consistently rising. Pairing solar with battery storage makes the financial case even stronger, allowing homeowners to bypass expensive peak rates and keep their homes powered when the grid is stressed or offline. Even with the incentive stepping down, the lifetime savings from solar in 2026 remain extremely strong. What Homeowners Should Take Away The combination of rising utility rates and a reduced tax credit might seem like a reason to wait, but it’s actually the opposite. The longer homeowners remain 100% dependent on the grid, the more expensive their energy costs become. Solar continues to offer protection from rate volatility, greater control over monthly expenses, and long-term savings that significantly outweigh the loss of part of the tax credit. 2026 is a reminder that the cost of utility power is only moving in one direction — and investing in your own energy system is one of the smartest ways to stay ahead.
