You may be wondering how long a solar panel system will last? This is especially common when you are actually considering implementing a system into your home. Here at SEM Power, we want to make sure you have all the information you need to get you the best results. We specialize in solar power and take pride in being one of the best solar companies in Florida. 


How Long Do They Last?

Anytime a home or business owner makes a significant investment in their property; they want to be assured that it’s a good one. No one wants to spend their hard-earned money on something only to find out after it’s been paid off that it needs to be replaced or that it’s reached the end of life. And that goes double for something that’s semi-permanently attached to the exterior of their home like solar panels.


When you consider the way, solar panels work and are affixed to a property – onto the roof and essentially drilled and anchored into the rafters – replacing them every few years would be an absolute pain. Not only would it be expensive, but it could open up the potential for structural damage or roof damage. Luckily, though, solar panels don’t need to be replaced often – if ever. 


What is the Life Expectancy of a Solar Panel System?

All of that aside, the numbers that you’ll typically hear are that solar panels last about 25 to 30 years. That doesn’t mean that sometime between two and three decades in your panels are just going to stop working. As we illustrated above, your panels will most likely continue working – and working at a very high level – well after that. However, around that time, your panels may see a drop in output that’s considered “significant.” According to EnergySage, panels with a 0.8% degradation rate will be operating at 82.5% of their original ability, while panels with a 0.5% degradation rate will be operating at over 87%. And, of course, the technology is going to continue to improve, which means degradation rates may continue to slow. 

Additionally, these numbers aren’t referring to some sort of “test” panels that are kept in ideal conditions in a climate-controlled building somewhere. These are real numbers being reported by solar panels that are in regular use all over the country. Due to the materials, they’re made with, solar panels are highly durable and resilient, and it’s rare that the actual components of the panels break from within. Sure, during a particularly vicious hurricane you may have a solar cell that cracks, but even then it doesn’t mean the panel itself will cease to function. A broken cell can actually still produce 85%-100% of its potential output!
