Your solar questions for Louisburgh
How much do solar panels cost in Louisburgh?
A 4kWp system in Louisburgh 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 3,364 kWh/year, paying for itself in 4-6 years.
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 Louisburgh?
With a net cost of €3,200-€6,200 after the SEAI grant and savings of €872+ per year plus export income, a typical solar system in Louisburgh pays for itself in 4-6 years. After payback, you get 20+ years of near-free electricity.
Can I get solar panels on an east or west facing roof in Louisburgh?
Yes. East or west-facing roofs still produce 80-85% of the output of a south-facing roof. Many installers recommend splitting panels across east and west to spread generation throughout the day, which can actually improve self-consumption.
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.
Is my roof suitable for solar panels in Louisburgh?
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 do I get the SEAI grant in Louisburgh?
Apply online at seai.ie with your MPRN and Eircode. Use an SEAI-registered installer. Do not start work before your Letter of Offer. After installation, complete a BER assessment. The grant is paid to your bank within 4-6 weeks.
