What Fenagh homeowners ask about solar
How much do solar panels cost in Fenagh?
A 4.4 kWp system in Fenagh 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 3,644 kWh/year, paying for itself in 4-6 years.
What size solar system do I need for my home in Fenagh?
Most homes in Fenagh benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 87% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
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.
What happens to my solar panels if I move house in Fenagh?
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.
Can I get solar panels on an east or west facing roof in Fenagh?
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.
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.
Is my roof suitable for solar panels in Fenagh?
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.
Can you go off-grid with solar in Fenagh?
Fully off-grid setups are rare in Fenagh. 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.
