If you’ve been researching rooftop solar panels, you’ve probably found articles online about early models installed in the 80s that still produce power today. Which brings up a good question – how long do solar panels last? 

While a number of factors can impact solar panel lifespan, the good news is that they are designed to last a minimum of 25 years. This number is set by manufacturers, and should homeowners see below-average production, they can file a claim to get those replaced. However, problems like that are rare, and most solar panels and energy systems last well beyond that with proper maintenance and routine inspections from a licensed solar energy company.

How Long Do Solar Panels Last In Florida?

American-made solar panels come with a warranty that guarantees their performance for 25 years or more. However, this does not mean that solar panels will stop producing electricity after this time period. While solar panels are designed to be durable, there are several factors that can shorten their lifespan, including:

Quality of Materials: This is the most important factor determining how long solar panels last. The thickness of the panel, glass coating durability, and internal wiring all contribute to optimal performance over time. Choosing American-made solar panels is a must for homeowners who want their systems to last beyond the manufacturer’s warranty period. 

Installation: Solar panel installation is another factor that can impact the lifespan of a residential solar system. If not done correctly, solar panels, inverters, and wiring can be damaged, leading to reduced performance. It can also stress individual components and be a safety hazard for your home.

Weather: Extreme weather conditions, such as high winds, hail, or flying debris, can damage solar panels and cause the need for repairs. 

Maintenance: Regular solar panel maintenance, such as cleaning and inspection, can help prolong the lifespan of solar panels.

Usage: Just like a car or heavily used appliance, normal wear and tear can decrease the lifespan and production of solar panels. 

How To Increase The Lifespan Of Home Solar Panels 

Proper maintenance and care is the best way to ensure maximum solar panel performance and longevity. What maintenance should Florida homeowners be focused on? 

Keep Them Clean: Dirt, debris, and other contaminants can reduce the efficiency of solar panels. Regular cleaning can be done with a water hose from the ground level of your home. Avoid harsh cleaners or brushes that can damage the exterior coating. 

Check For Damage: Inspect solar panels for any physical damage, such as cracks or chips, which can impact their performance. If any damage is detected, it’s important to have it repaired quickly to avoid disruptions in energy production.

Monitor Performance: The first indication of a problem with solar panels can usually be found using a solar panel performance app. Enphase Enlighten is one of the most popular ones for homeowners. The app is an easy way to track solar panel production and will usually let you know if there is a drop in performance or if the system is showing errors.
