Do I need to use an installer based in Offaly?

Does Dermot McGrath only do solar PV panel installation?
On the SEAI register they are listed for solar PV panel installation. They may well do other work, but solar PV panel installation is the measure their registration covers, so it is the one they can process a grant for.
