Solar panels come with warranties in which the manufacturer gives you the guarantee that your panels will last for a certain number of years. These warranties often last between 10 and 20 years, but some are as long as 25 years. First, these warranties guarantee that your solar panels won’t fall below a certain performance level. They also cover unexpected damage to your solar panels from storms and other causes outside of your control.
It’s important however to note that your solar panel warranty may stipulate that your panels are only covered if they are adequately maintained. For instance, if you don’t clean your solar panels regularly and built-up debris cuts their useful lifespan short, then your warranty may not cover it.
Solar panels come with a larger price tag than many household appliances. But the good news is they also require less maintenance and have way longer lifespan The only regular maintenance needed for your solar panels is cleaning and an annual inspection by a solar technician or most adequately by your installer. Otherwise, as long as your panels are in good condition, they won’t need additional maintenance throughout the year.
