It’s important to know when it’s time for a solar replacement. Sometimes, panels need a good cleaning to get them back up and running at full capacity. Other times, though, they simply reach the end of their lifespan and need to be replaced altogether.

Synergy Home Solar, the top name for solar panel maintenance in Lexington, KY, recommends keeping an eye out for these warning signs:

Panel Cracks

If you notice any visible cracks, it’s time for a solar panel replacement. Even if the cracks are very small, they can still lead to significant performance losses and should be replaced immediately.

Poor Performance

If your solar panel system isn’t producing as much energy as it used to and continues to be so even after maintenance, it may need a replacement. This could be due to age, wear and tear, or even damage from the elements.

Decreased Efficiency

A significant and unexplainable decrease in efficiency is also a sure sign that you need to replace your solar panel. Make sure to check your system regularly and note any changes in its performance. Routine solar panel system maintenance can help prevent drops in efficiency.

Damage Caused by Animals

Birds, rodents, or other animals can cause physical damage to solar panels. These damages can lead to inefficiencies and performance losses that oftentimes cannot be reversed. Regular solar panel inspection should be done to check for any animal damage.


If your panels have started to rust or corrode, they are likely past their useful lifespan and must be replaced. Ensure to keep an eye out for any signs of corrosion, which can indicate a problem that needs to be addressed immediately. For instance, most residential solar panels should be able to last several years, but if you find signs of corrosion, then they may need to be replaced sooner.

Excessive Debris and Dirt

If you live in an area with high levels of dust, then your solar panel may need a replacement due to debris build-up–especially if you don’t have regular maintenance. Be sure to clean your panels regularly to ensure they operate at peak efficiency. A solar panel cleaning includes waxing, cleaning, and replacing any parts that may be damaged or worn.
