What Janesboro homeowners ask about solar
How much do solar panels cost in Janesboro?
A 4kWp system in Janesboro 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 3,476 kWh/year, paying for itself in 4-6 years.
How does shading affect solar panels in Janesboro?
Shading from trees, chimneys, or nearby buildings can reduce output significantly. Modern systems use optimisers or microinverters so that shading on one panel doesn't drag down the whole system. Your installer will assess shading during the site survey.
What happens to my solar panels if I move house in Janesboro?
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 is the payback period for solar panels in Janesboro?
With a net cost of €3,200-€6,200 after the SEAI grant and savings of €938+ per year plus export income, a typical solar system in Janesboro 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 Janesboro?
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 planning permission for solar panels?
Most residential solar installations are exempt from planning permission, provided panels don't project more than 15cm from the roof and don't cover more than 50% of total roof area.
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.
