What is the Difference Between Mono Solar Panels and Poly Solar Panels in Service Life?
Both types of solar panels have two warrantees, a physical warranty and an efficiency warranty. The physical warranty is generally 15 to 30 years and covers any physical damage. The efficiency warranty is 20 to 30 years and concerns the efficiency of solar panels after 25 years. Thus, an 80% efficiency warranty after 25 years means that the panels will produce 80% of the electricity they produced in their first year after 25 years. Although they produce less energy, the panels still work very well.
That said, the duration of warranties varies by the manufacturer rather than panel technology. It is up to you to choose the manufacturer offering the best warranties.
