@John S Lewis  a few ideas, some easier than others...1) search lien records through the county2) check the system itself (panels and indoor hardware) for labels placed by the installer in case of service needs, pretty common, then call them up3) see if any neighbors have similar systems and ask them who they used, then call them up4) call local installers and ask whether they worked on that property5) looked up previous owners and ask them who installed, but check with installer about status rather than rely on the foreclosed party's representation6) Don't worry about it?
