What breaks in 11 years? Solar panels and batteries both last longer than that.

As for your other point of becoming obsolete, why care about chasing latest fads for home appliances.

Are you sure? Lots of people are telling me that batteries only last 4-5 years tops and solar panels usually burn out before 10 years /s

I particularly love when they are telling me that my 11 year old Prius' batteries will only last 5 years before they are junk.

This is totally wrong. I work in the industry. Solar panels should last for 30 years, but they degrade in capacity by 0.5 to 1% per year, depending on environmental conditions (temp, radiation, etc). Lithium batteries from tier 1 suppliers can last at least a decade of regular use. It depends on how their cycling and state of charge is managed. If you keep them between 20% and 80% charge, they can last incredibly long.

/s is the sarcasm tag.
