Goodbye to the idea that solar panels “die” after 25 years. A new study says the warranty does not mark the end, and performance can last for decades. Arrays built in the late 1980s still produced more than 80% of their original power. The long-term economics look better than many people believe. bocvip.com/1170237/goodbye-to-
