Frequently Asked Questions About Solar Panels in Blarney
How much do solar panels cost in Blarney?

Are solar panels worth it in Blarney?

Is my roof suitable for solar panels in Blarney?
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.
How long do solar panels last?
Modern solar panels are warrantied for 25-30 years and typically last even longer. Panel efficiency degrades by about 0.5% per year, so after 25 years, your panels will still produce around 87% of their original output. Inverters typically last 10-15 years and may need one replacement.
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.
What is the payback period for solar panels in Blarney?
With a net cost of €3,200-€6,200 after the SEAI grant and savings of €982+ per year plus export income, a typical solar system in Blarney pays for itself in 4-6 years. After payback, you get 20+ years of near-free electricity.
How long does solar panel installation take?
A typical residential installation takes 1-2 days. This includes scaffolding, mounting the panels, wiring, inverter installation, and connecting to the grid. Your installer handles the ESB Networks notification (NC6 form).
