Domestic solar gets the headlines, but commercial solar is one of the fastest-growing opportunities for Irish installers. Businesses, farms, schools and community buildings have large roofs, daytime electricity use and strong reasons to cut energy costs. The work is different from domestic jobs in a few important ways.
Bigger systems, different connection rules
Domestic systems typically go through the NC6 micro-generation route. Larger commercial systems can exceed micro-generation limits and need a different connection process with ESB Networks. Check the ESB Networks generator connection guidance early in the project.
Supports for businesses and farms
SEAI offers supports for non-domestic solar, and tax measures such as accelerated capital allowances can apply to qualifying energy-efficient equipment. Rules and eligibility change, so always point clients to the latest information on seai.ie and to their accountant, rather than quoting figures from memory.
Longer sales cycles
Commercial customers compare payback periods, involve several decision-makers and take longer to decide. Structured follow-up matters even more than in domestic sales.
More paperwork
Proposals, energy analysis, method statements, safety documentation and staged invoicing all add admin. Keeping it organised is what separates installers who grow in commercial from those who find it a headache.
