I thought there was a topic search available on this forum. But I can’t seem to find it. That said, I am looking to remove and replace my existing 22 panel system in order to reroof my home. I discussed this with the installer when I got the install quote, but mistakenly failed to insist it be included in the final bid. Suggestions on fair cost? The array is two rows of 11 panels with micro inverters on a very minimally, single story, pitched roof. The roofing contractor asks that the system be removed down to the posts which he can work around. On the sidenote, my understanding is panels with micro inverters are pretty much “plug and play “. If this job is not requiring technical skill, I don’t think i’d mind getting up on the roof and doing it myself. Im told the panels weigh approx 40lbs. Thanks in advance for any input.

Crap, now i find the “search” option. My apologies for question that has probably been asked numerous times -
1.) I've no experience or knowledge on cost of removal/reinstall of a PV system on a roof, but know that if you DIY it you'll most likely void any warranty you may have.
If someone says "no problem - DIY doesn't void warranty ", get it in writing from whoever you'd make a warranty claim to.
2.) If you contract it out which is, IMO only, probably the safer way to go, my SWAG is it won't be cheap. Solar installers reading your post most likely have a much better feel for cost than I might guess.
3.) In any case, I'd also think the all round best way to go would be to have the original installer to the PV removal/reinstall. I'd respectfully suggest you just don't leave them with the opinion that you think you have no choices on who does the work - prices go up more easily if they think you think they are the only option to doing the work.
4.) While you're having the PV work quoted - and I would get a few quotes, I'd make sure that both the roofer and PV contractor know you expect each one to stay out of the other's way and that, for example, the roofer doesn't touch, or need to move any stacked panels or that the PV contractor doesn't damage the new roof deck in any way during reinstall of the panels .
3.) FWIW, be prepared to act as your own project manager/coordinator. Don't expect either contractor to either look out for your best interests or the other contractor's foulups/shortcuts. I'd sit on the roof, out of the way with my mouth shut while any work of any sort was being done and take a lot of pictures. I did that w/my install on a concrete tile roof that included repapering and some other roof remediation. I'm glad I did.

Oops now you get to learn a very expensive lesson. You were told to put a new roof on before panels, now you will learn the ole fashion way, loosing money. You just thought solar was going to save you money.
It was inexpensive to put them up. Going to be real expensive to remove them and reinstall them again. Hope you have some spares because some panels will not survive being moved and reinstalled. Enjoy and learn.Last edited by Sunking; 05-22-2020, 12:49 PM.MSEE, PEComment

FWIW, we charge $75/panel to R&R an array we installed, and $100/panel for those we did not originally install. This may seem inexpensive compared to what people pay for original installation, but we actually find R&Rs to be good business as there is no permitting hassle involved (with some exceptions), we can do them quickly, and we enjoy correcting the many, many screwed up installs out there... You wouldn't believe how many times we have found miswired arrays. Half the panels not hooked up, different size strings wired in parallel, burned wiring and connectors, etc....BSEE, R11, NABCEP, Chevy BoltEV, >3000kW installedComment

Somewhat but not entirely anecdotal, after watching ~ 130 + arrays go into my HOA from contract signing to startup, I've got no trouble believing what you just wrote.
I might add that the better and more established local electrical contractors/installers around here seem to do a better/cleaner/more thorough job on installs than the bottom feeders like Tesla/SolarCity, Sunrun and Vivant.Comment

Hey guys, Thanks for the feedback. @Sunking...my roof had a minimum of 5 years before needing said reroof. Timing wise, I was able to get in just before NEM 1.0 ended with PG&E. Also was the concern of possibly missing out of the 30% tax credit. I tried to consider all factors when making that purchase. But obviously failed to include an R/R of the panels in the original contract. So, yes it may be a bit of a lesson, but not one that justifies your snide remark. By the way, it’s “L O S I N G”, not “L O O S I N G”. Of course, inability to spell is free. So you have me there. How’s that for an observation!Comment

Charging $/watt is a ridiculous metric to calculate cost for this task. It's like telling someone that they'll have to pay more money because their car has more horsepower to get the same tires rotated as a car with less horsepower.
As usual, Solarix gets it right and shows us why he's still in business.Comment

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.Comment
