A common query that a typical residential solar panel customer asks is, “how long do solar panels last?” As a common rule of thumb, the lifespan of solar panels will probably be between 20 – 25 years, relying on the manufacturer. It’s necessary to note that this doesn’t suggest that they’ll stop producing electricity after that period. Solar panels are usually constructed robustly and to withstand every kind of climate situation. Because they don’t have any moving parts, you must expect your solar panels to last for many years.
