What Barntown homeowners ask about solar
How much do solar panels cost in Barntown?
A 4.4 kWp system in Barntown 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 3,860 kWh/year, paying for itself in 4-6 years.
What roof direction is best for solar panels in Barntown?
South-facing roofs produce the most electricity (100% of potential). South-east and south-west roofs produce around 95%. East or west-facing roofs still produce 80-85%. North-facing roofs are generally not recommended for solar panels in Ireland.
How much electricity will solar panels generate in Barntown?
Based on Wexford county data, a 4kWp system in Barntown generates approximately 3,860 kWh per year, covering 92% of average household use (4,200 kWh/year). Wexford receives around 1,540 sunshine hours annually.
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).
What happens during a power cut?
Standard grid-tied solar systems shut down during a power cut for safety reasons (to protect ESB workers). If you need backup power, you can install a hybrid inverter with battery storage that provides power during outages.
What is the payback period for solar panels in Barntown?
With a net cost of €6,500–€7,200 after the SEAI grant and savings of €1158+ per year plus export income, a typical solar system in Barntown pays for itself in 4-6 years. After payback, you get 20+ years of near-free electricity.
Can I sell excess solar electricity?
Yes. Under Ireland's Microgeneration Support Scheme, you sell surplus electricity at 15-25c/kWh. You need a smart meter (ESB Networks installs free). The first €400/year of export income is tax-free.
Can you go off-grid with solar in Barntown?
Fully off-grid setups are rare in Barntown. 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.
