Most installers cover their whole county rather than one town, so it is worth confirming your own address when you call.
Should anything be done before the installation?
Insulation comes first on any home energy upgrade. A well-sealed house needs a smaller system and runs at a lower cost, and attic and wall insulation carry SEAI grants of their own. Ask about the fabric of the house when you speak to CMC Electrical Contracting Ltd / Duffy Solar.
What grant can I claim on work by CMC Electrical Contracting Ltd / Duffy Solar?
Grants may be available for eligible homes. SEAI lists support of up to €1,800 for solar panels as of July 2026, and SEAI decides eligibility. Confirm how the application and payment work with CMC Electrical Contracting Ltd / Duffy Solar and with SEAI before any work starts.
Does my home in Mayo qualify for a grant?
A home built and occupied before 2021 usually qualifies. Housing across Mayo varies a lot, so the survey decides rather than the county. A registered installer confirms eligibility during a free survey before anything is committed.

It is worth knowing how the total breaks down before the survey.
