Frequently Asked Questions About Solar Panels in Robertstown
How much do solar panels cost in Robertstown?
A 4kWp system in Robertstown 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 3,540 kWh/year, paying for itself in 4-6 years.
What happens to my solar panels if I move house in Robertstown?
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.
Do solar panels increase property value in Robertstown?
Yes. Solar panels improve your BER rating and can increase property value by up to 4%. Buyers increasingly look for energy-efficient homes with lower running costs. A solar system in Robertstown is a long-term investment in your property.
What is the payback period for solar panels in Robertstown?
With a net cost of €3,200-€6,200 after the SEAI grant and savings of €928+ per year plus export income, a typical solar system in Robertstown pays for itself in 4-6 years. After payback, you get 20+ years of near-free electricity.
Is my roof suitable for solar panels in Robertstown?
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.
Do I need a smart meter for solar panels?
You need a smart meter to sell surplus electricity back to the grid. ESB Networks installs smart meters for free. Your installer submits the NC6 form to ESB Networks after installation, which triggers the meter upgrade if needed.
Can I add a battery to my solar system?
Yes. A home battery (typically 5-10 kWh) stores excess solar electricity for evening use. This increases your self-consumption from around 30-40% to 60-80%. Batteries currently cost €3,000-€6,000 and are not yet covered by the SEAI grant.
