The cracked panel may work for weeks without losing performance in warm, windless, and rainless weather. However, the first rain or cold may lead to permanent damage, forcing you to replace a whole panel. . Solar photovoltaic panels can last for an extended period even if cracked, but the duration and performance will depend on various factors, including the severity of the crack, environmental conditions, and maintenance. Generally, a solar panel could function for 5 to 25 years after developing. . When something is cracked, it's usually useless, although it no's not always the case. Moreover, broken panels pose safety risks, especially if the damage exposes electrical components.
