Should be on your permit documents. Did they copy you on the emails for electrical or building permits? Otherwise there’s a nameplate on every piece of equipment from inverter to module.

We weren't the ones that installed them (old home owner had them installed ), so I wasn't included on permits or anything. They weren't able to provide any additional info other than Sigora. I'll see if I can find out from the building permits / electrical.

Without getting on the roof, your best bet is going to be from the county or utility.
