How Long Will My Solar Panels Last?



Solar panels are quickly becoming one of the most popular options for households interested in saving money and conserving resources. You might find yourself asking, "How long will my solar panels last?"


If you're considering purchasing solar panels you'll want to know more about their life span and upkeep before you make an investment. You might be surprised at how long the panels for this popular money-saving energy option last.


The Lifespan of Solar Panels

On average, solar panels last approximately 25-30 years, depending on several factors, including climate and maintenance over the years. Solar panels offer significant savings on energy for their lifespan. Once you've had them for 25 years, you may notice a reduction in the energy output of a few kWh per week. That's because, over time, the solar panels begin to degrade and have less capacity to absorb sunlight to convert to solar energy.


This is especially true if they're located in hot climates with plenty of sunny weather. On average, you can expect to have a degradation rate of .5% per year, so after 25 years you will have panels that work at just under 90% of their original efficiency. These numbers are approximate; having higher-quality panels means longer life spans, and vice versa.


Save Big Money with Solar Installation

Solar panel installation can save homeowners big bucks on their energy bills. In fact, on average, homes with solar panels can save between $10k and $30k per year. Some factors related to the overall savings and effectiveness include:

  • Size and angle of the roof

  • Number of sunny days

  • Local electricity rates


In areas where electric costs are high and you receive a lot of sun, the savings make the initial investment more than worth it.


The Benefits of Adding Solar Panels

There are many benefits associated with installing solar panels. One benefit homeowners should consider is the additional value they add to the home. On average, solar panels add approximately $15,000 to a home's list price.


One of the most notable benefits aside from energy savings is the environmental impact. Using solar panels reduces your carbon footprint and helps create cleaner air and water.


Panel Components

Besides the panels, other parts and accompanying pieces are installed to ensure the system is secure and working correctly. These parts need occasional replacing, too, as time goes on. Some components connected to the panels include:

  • Racking

  • Inverter

  • Solar battery


It's important to monitor the condition of the racking. This component holds the panels in place on the roof and is subject to wear from exposure to the elements. Keeping an eye on the racking could save you from a costly repair down the road.


The inverter is essential for the solar panels to operate correctly. This tool converts the DC electricity into home-use AC electricity. Replace this component approximately every 10-15 years.


The solar battery stores excess power and is a great idea to have installed with the solar panel as it can maximize your cost savings. It usually has a 10-year warranty. Check the functionality of your battery every ten years or sooner to ensure it's operating properly.


The average lifespan of a solar panel is 25-30 years, but it can be more if you invest your time and resources into it. Purchase high-quality solar panels to get more use and capability over the years, and don't forget to inspect your entire solar system regularly to determine what might need replacing.


You can save plenty of money on energy expenses for your home while adding value to your home with top-quality solar installation.
