Dunmanway solar panel questions answered
How much do solar panels cost in Dunmanway?
A 4kWp system in Dunmanway typically costs €5,000-€8,000 before grants. After the €1,800 SEAI grant and 0% VAT, the net cost is €3,200-€6,200. The system generates approximately 3,628 kWh/year, paying for itself in 4-6 years.
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.
Do solar panels work in winter in Cork?
Yes, solar panels generate electricity all year round. While output is lower in winter, Cork still receives usable daylight hours even in December. Annual generation figures (3,628 kWh for a 4kWp system) already account for seasonal variation.
What is the difference between solar PV and solar thermal?
Solar PV panels generate electricity from sunlight. Solar thermal panels heat water directly. For most Irish homes, solar PV is the better investment: it's more versatile, qualifies for the SEAI grant, and you can sell excess electricity. Solar thermal only heats water.
What is the Microgeneration Support Scheme?
The Microgeneration Support Scheme allows homeowners to sell surplus solar electricity back to the grid at 15-25c/kWh. You need a smart meter (free from ESB Networks) and a grid-connected system. The first €400/year of export income is tax-free.
What size solar system do I need for my home in Dunmanway?
Most homes in Dunmanway benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 79% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
What is the payback period for solar panels in Dunmanway?
With a net cost of €3,200-€6,200 after the SEAI grant and savings of €995+ per year plus export income, a typical solar system in Dunmanway pays for itself in 4-6 years. After payback, you get 20+ years of near-free electricity.
