Cobh solar panel questions answered
How much do solar panels cost in Cobh?
A 4.4 kWp system in Cobh typically costs €8,300–€9,000 before grants. After the €1,800 SEAI grant and 0% VAT, the net cost is €6,500–€7,200. The system generates approximately 3,628 kWh/year, paying for itself in 4-6 years.
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.
What happens to my solar panels if I move house in Cobh?
Solar panels stay with the property as a permanent fixture. They add value to your home for the next buyer. The SEAI grant does not need to be repaid if you sell. Your installer can transfer monitoring accounts to the new owner.
What maintenance do solar panels need?
Solar panels need very little maintenance. Rain keeps them clean in most cases. There are no moving parts. Your inverter may need replacing once in 25 years (10-15 year lifespan). Annual visual checks and occasional cleaning if near trees is all that's needed.
What is a BER assessment and do I need one?
A Building Energy Rating (BER) assessment is required after installing solar panels to claim the SEAI grant. A BER assessor visits your home and rates its energy efficiency from A1 to G. Solar panels typically improve your BER by 1-2 grades. The assessment costs around €150-€200.
Is my roof suitable for solar panels in Cobh?
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.
What is the payback period for solar panels in Cobh?
With a net cost of €6,500–€7,200 after the SEAI grant and savings of €1088+ per year plus export income, a typical solar system in Cobh pays for itself in 4-6 years. After payback, you get 20+ years of near-free electricity.
Can you go off-grid with solar in Cobh?
Fully off-grid setups are rare in Cobh. Most homes stay grid-connected and sell surplus back through the Microgeneration Support Scheme. A hybrid inverter with 10-20 kWh of battery storage covers evenings and power cuts, which is what most people searching "off-grid" actually want. A true off-grid system needs a much larger array and battery bank, and you lose the grant-supported export income.
