Hi Alyssa
Ah, wholesale net metering, I misread that earlier and assumed it was retail net metering. I was under the impression that almost everywhere in the US had retail net metering, is Florida different or did I misunderstand that?
Regarding the warranty, I think your decision largely comes down to your level of comfort with risk. I would be more comfortable to keep the price difference in my pocket in case of issues, but other people would be more comfortable paying more upfront for peace of mind. It really comes down to personal preference.
All the best. Would love to see a picture of the install once complete.
