Goodbye to the idea that solar panels “die” after 25 years. A new study says the warranty does not mark the end, and real-world performance can last for decades (www.ecoticias.com)

I have a few solar panels installed in 2008.

They are mounted in an extremely bad location: on a south facing wall, without proper airflow on the back side.

They continue to work, even if output is degraded. Newer planels installed in the same location overheated and their elements cracked, indicating inferior manufacturing quality, but the oldest batch is not showing this symptom.
