Panel Removal for reroof

Does a newer 345 watt module take more time to remove than an old 190 watt module? By the watt a 345 watt module would cost over 50% more to remove than the 190 watt module.

Yes. The extra electrons make the 345w heavier.

Its not uncommon (especially on older arrays that have lots of small panels) to upgrade them to many fewer new panels. The labor is a lot less and they can get tax credits on them, use less space on the roof and looks better too. The old panels do last forever and don't require replacement, but can usually find off-gridders or RV'ers looking for a deal on used panels.- sometimes it is actually less expensive to upgrade than to R & R

No, but the second half of that operation, replacing a single 345 Watt module would take less time than removing two 190 Watt panels. If you let the installer make some money on the purchase of the 345 Watt panel you may get a good value as @solarix suggested.

I was just making the point that it makes no sense to charge by the watt for panel removal as all panels are roughly the same to handle.

Say I buy a roof full of 345 watt modules today and next year a hail storm wipes out the roof which means removing all the panels to replace the roof. Why should I pay over 50% more to remove each panel than someone else who has 190 watt panels because they have had solar for a number of years?

Crap, now i find the “search” option. My apologies for question that has probably been asked numerous times

The built-in search tool in the Forum software does not work very well at all.
Far better is to do a Google search and include the string "site:solarpaneltalk.com" (without the quote marks) as part of the search

A friend of mine who is a licensed electrician and has done solar for over 15 years said that they may just be using price per watt as that is common in the solar industry. They may adjust the price per watt so the price to remove a single panel is the same no matter how many watts.
