When are you going to grow up?

Why is a 63 year old man acting like a seven year old? Josepi, Gimmie

You are one sick puppy. If you actually had a life you wouldn't have to
forge someone elses.

I did not write the troll below about not writing the post.

I have never used BS hashing to make me look more important.

There's actually far more to this than a simple ROI calculation.  Other
important factors are Cost of Capital and Opportunity Cost, plus an educated
guess regarding what's going to happen to them over the next 20 years.

Also, many folks fail to consider the lifetime of the PV installation vs. the
lifetime of the roof surface it's installed over.  If you need to replace the
roofing before the PV is junk, then you must either pay for a second
installation or junk the PV early.  Either way, you are out money.

(Don't put me in anti-PV group, I own a modest system myself.  I just don't
expect it to ever pay for itself.)

Agreed, that's something that I considered. My tiled roof is probably
around 40 years old. Whether it will last for another 20-25 years without
needing renovation is anyone's guess.

I wouldn't put a PV on it if it's more than 20 years old.
