How to read these case studies
Every roof is different, even within the same part of Dublin. A well designed system starts with roof geometry, shading and safe access, then matches PV size to the household’s day time usage. We share case studies because they show the practical side of solar panel installation in Ireland: where the array sits on the roof, how we route cables, and where we locate electrical equipment so that it stays serviceable and tidy.
You will notice we talk about choices rather than promises. For example, a battery can increase self consumption, but it only delivers strong value when the household has surplus solar during the day and meaningful usage later in the evening. In other homes, adding PV first is the better priority. The goal is not the largest system, it is the right system for your meter, your budget and your roof.
If you want to understand pricing, we keep our costs page updated with realistic 2026 ranges. Many Dublin homeowners see 3 to 6 kW systems priced around €6,000 to €12,000 after the SEAI grant, often €7,000 to €10,000 for a typical home depending on roof complexity and equipment. For grant eligibility and how the €1,800 maximum is calculated, see the SEAI grant page.
