What Castletownroche homeowners ask about solar
How much do solar panels cost in Castletownroche?
A 4.4 kWp system in Castletownroche 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 3,628 kWh/year, paying for itself in 4-6 years.
How does shading affect solar panels in Castletownroche?
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.
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 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.
What maintenance do solar panels need?
Solar panels need very little maintenance. Rain keeps them clean in most cases. There are no moving parts. Your inverter may need replacing once in 25 years (10-15 year lifespan). Annual visual checks and occasional cleaning if near trees is all that's 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.
Is my roof suitable for solar panels in Castletownroche?
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 Castletownroche?
Fully off-grid setups are rare in Castletownroche. 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.
