Maintenance & Cleaning: Clean your system and ensure it is free of dust, dirt, leaves, or other debris that will block sunlight and lower your system's energy production. Roof & Installation Quality: If the panels are not mounted or installed correctly on the rooftop, their lifespan can be drastically diminished.
More data is needed to understand when, why, and what volumes of solar panels are reaching end of life, but weather damage and installation errors are expected to accelerate end-of-life issues. There are many considerations on whether to voluntarily replace solar systems before their end of life.
Some consumers and plant operators may choose to upgrade their solar panels before the warranty period expires or to take advantage of technological improvements—a practice known as repowering. Why Is PV End-of-Life Management Important?
In response, asset owners are increasingly turning to repowering solar PV systems: the process of replacing or upgrading aging solar infrastructure to improve performance, ensure compliance with updated standards, and extend system life.
