Now I have seen everything!!!!!!

They are doing a hard sell on solar panels in my area. Basically its sold as instead of paying the electric bill you pay.......an electric bill. Except after the panel is paid off you will get a credit as that power will be going back into the grid. Now the "loan" for the panel is for, lets say, 15 yrs......but the warranty only is for 10. So you say the panel will last for 25 but you aren't really sure as it starts to fail you will only stand behind your product for less time than it will take me to pay it off? Might be off on the pitch, but I think I have the general scheme portrayed correctly.
