How Long Do Solar Panels Typically Last When Installed on a Roof?

Wondering how long those shiny solar panels on your roof will actually last? You’re not alone.
The quick answer? Most solar panels last 25 to 30 years. But here's the kicker – they don’t just stop working after that. They keep producing energy, just at a lower efficiency.
What Affects Solar Panel Lifespan?
Not all solar panels age the same. Some stay efficient for decades, while others might slow down earlier.
Here’s what matters:
- Quality of Panels – Higher-quality panels last longer (surprise, surprise).
- Installation – Poor installation = faster wear. Go with solid mountings like the EcoFlow Rigid Solar Panel Mounting Feet ($19). Secure panels are happy panels.
- Weather – Panels take a beating from UV rays, wind, and snow. Tilt mounts like the EcoFlow 50'' Tilt Mount Bracket ($89) help position them perfectly for max exposure and durability.
- Maintenance – Clean panels last longer. Dust and dirt? Not their friends.

What Happens After 25 Years?
Your panels don’t die. They just slow down. By year 25, most panels still produce about 80% of their original capacity.
Think about it. That’s still free electricity for decades.
Need a long-term setup? A ground mount like the EG4 BrightMount Solar Panel Ground Mount Rack Kit ($310) keeps panels angled right and in top condition, stretching their lifespan even further.

Can You Make Them Last Longer?
Absolutely. Here’s how:
- Use durable mounts that can handle wind and bad weather.
- Adjust the tilt of your panels for max sunlight.
- Keep them clean – a quick rinse every few months does wonders.
- Check for damage regularly. Cracks and loose wires cut lifespan.
Is It Worth the Investment?
Yes. Even after 30 years, you’re still getting a return. Solar panels are one of those set-it-and-forget-it kind of investments.
With the right gear – like the EcoFlow Tilt Mount Bracket or EG4 Ground Mount Kit – you’re set for the long haul.
So, if you’re eyeing solar, think of it like this: decades of energy, minimal fuss. And that sounds like a win to me.
