These panels are designed with degradation in mind; manufacturers often provide a limited power warranty of 25 years, guaranteeing that the panels will maintain at least 80% of their output capacity for the duration of this period. Some solar panels even exceed this expectation, maintaining efficiency levels higher than 80% past their 25-year mark.
Although it’s uncommon for a solar panel to completely stop producing energy, the degradation rate may be significant enough in time that you should replace the panels entirely. Beyond production warranties for the solar panels, many manufacturers offer shorter warranties for the related equipment.
Here are some factors that affect the life expectancy of solar panels: The quality of the solar panels themselves is a vital factor that influences their longevity. High-quality panels, manufactured with stringent quality control and premium materials, are less susceptible to degradation over time.
The surrounding environment and climate have a direct impact on the longevity of solar panels. Panels exposed to harsh weather conditions, such as extreme temperatures, hail, or high winds, are more susceptible to physical damage.
Solar panels are generally very durable. Most solar panels are designed and tested to withstand the elements like hail, high winds, and heavy snow loads. And thanks to their lack of moving parts, solar panel systems usually require little to no maintenance. Still, maintaining your solar panels can boost production.
Given the typical degradation rate of about 0.5–0.9% per year, a 10-year-old solar panel can be expected to retain 90–95% of its original efficiency. This means that if a solar panel started with an efficiency of 20%, it should still deliver around 18-19% efficiency after a decade. Should I Replace 15-Year-Old Solar Panels?
Lifespan of Solar Panels: A Comprehensive Guide 2024
Typically, the lifespan of solar panels is anywhere from 25 to 30 years, making them a remarkably durable component of solar photovoltaic (PV) systems. This longevity surpasses that of many other household systems, such as boilers, which usually have a life expectancy of 10 to 15 years.
