# How long does a solar panel last?

**Typical lifespan: 25–40 yr**

A framed sheet of silicon cells under glass that converts sunlight into direct current.

> Manufacturers warrant about 80-85% of original output at 25 years.

## How that compares

*Solar panel against things of a similar time.*

- Solar panel: 25–40 yr
- Komodo dragon: 25–35 yr
- Toilet: 20–50 yr
- Great hammerhead: 20–44 yr
- Three-toed sloth: 20–40 yr
- Front door: 20–60 yr
- Shortfin mako shark: 28–32 yr
- Harpy eagle: 25–35 yr

## What that means over time

*Assuming the typical lifespan above and immediate replacement.*

| Period | How many you would buy |
| --- | --- |
| Per year | 0.0333 replacements |
| Over 10 years | 1 of them |
| Over a 30-year mortgage | 1 of them |

> Lifespans are medians under ordinary use, not guarantees. Maintenance, how hard it is used, and build quality move individual examples a long way in both directions — which is why the range above is as wide as it is.
