How Long Do Solar Panels Really Last?

Solar panels are a great investment. They decrease our reliance on fossil fuels, save us money, and help us leave a smaller footprint on the environment. For these reasons, many consumers are turning to this source of renewable energy as a way to enhance their lives. 

The popularity of turning to solar in Ohio is here to stay. However, that doesn’t mean your system will last a lifetime. 

Discover how long your Cincinnati solar panels will last and what maintenance is required. This way, you know when it’s time to call your local Ohio solar company for help. 

Degradation Rate

Solar panels in Ohio, like anywhere, are subject to a solar panel degradation rate. This refers to the rate at which panels deteriorate over time. Studies show newer installations can last between 25 and 30 years, but that doesn’t mean they will perform optimally after that time.

According to a National Renewable Energy (NREL) study, solar panels have an average degradation rate of 0.5% each year, while some manufacturers claim a degradation rate as low as 0.3%. Even with degradation caused by UV exposure and unpredictable weather patterns, solar panels in Ohio can last and function at about 88% capacity after the 25-year warranty period.

Extending the Life of Your System

According to a study by the SEIA, Ohio ranks number 28 in the state’s ability to generate solar energy. This means you’ll want to maintain your system to get the most efficiency and guarantee you have power year-round. 

There’s good news — these systems are relatively easy to maintain. As long as they are in a sunny spot and cleaned regularly, they should function for many years to come. 

Your local experts can help you extend the life of your panel array and provide any repairs as needed. But there are also some things you can do at home or be on the lookout for. Here are some top tips for maintenance to ensure you get the most from your system: 

  • Document their efficiency. This way, you’ll know when something’s wrong.
  • Have panels cleaned once or twice annually.
  • Clear off debris like leaves, dirt, or snow.
  • Trim trees to avoid too much shade.

Get Extra Protection with a Warranty

Like many products, panels can be purchased with a warranty. Solar companies in Ohio and other states offer different types of warranty that cover a number of things, including:

  • Inverter warranty
  • Performance warranty
  • System warranty
  • Installation warranty

The type of warranty you purchase depends on what your Ohio solar company offers and your budget. Panels are a significant investment, and you rely on them for providing power for your home. Purchasing some type of warranty is the safest route to go when you buy panels and have them installed.
