The typical manufacturer's warranty on a solar panel is 25 to 30 years, but panels can last up to 40 years with care and attention.
For example, after 5 years, if a solar panel is producing less than 96.5% of what it produced (on average) when it was installed, then they will replace it (0.7% x 5 years = a maximum 3.5% reduction in power).So after 10 years, your panels are guaranteed to produce no less than 93% of the power they did originally.ne of the primary considerations you will face when investing in solar energy for your home or business is how long the system will last.
