I had my solar system installed 7 years ago. Has a 20-year warranty. Every company I talked to had a 20-25 year warranty. I haven’t even had to look at the thing or do anything with it in 7 years. And this is Canada where we can see wide-ranging temp changes and pretty cold weather. In a typical year, we can range from -20 to 35 Celsius.
Don’t know about the accuracy of this, but I scrolled past an article that said that the very state that I live in, South This seems like very good news, but I wonder if these figures include the cost of energy storage in Australia, is the first in the world to be 100% powered by solar power.
