Can I add a battery to my solar system?
Yes. A home battery (typically 5-10 kWh) stores excess solar electricity for evening use. This increases your self-consumption from around 30-40% to 60-80%. Batteries currently cost €3,000-€6,000 and are not yet covered by the SEAI grant.
Is my roof suitable for solar panels in Leenane?
Most roofs are suitable. You need at least 15-20 m² of unshaded roof space for a typical 4kWp system (10 panels). South, east, or west-facing roofs work well. Your installer will assess your roof's orientation, angle, and structural suitability during a site survey.
Do I need to clean my solar panels?
In most cases, rain keeps solar panels clean enough in Ireland. If your panels are near trees or at a low angle, an annual clean may improve output by 2-5%. Never use abrasive materials — a soft brush and water is sufficient.
