The warenty is 30-35 years and warenty is based off half life, our pv that had a 15 year warenty are already 25 years old and working perfectly, there is feild testing that has been going on with pv for over 50 years now, so 40 years is cutting the life really short, you are going to have to write those things in to your Will, and your kids might have to do the same.
