Your solar questions for Summerhill South
How much do solar panels cost in Summerhill South?
A 4kWp system in Summerhill South 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 3,628 kWh/year, paying for itself in 4-6 years.
How much electricity will solar panels generate in Summerhill South?
Based on Cork county data, a 4kWp system in Summerhill South generates approximately 3,628 kWh per year, covering 80% of average household use (4,200 kWh/year). Cork receives around 1,380 sunshine hours annually.
How does shading affect solar panels in Summerhill South?
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 Summerhill South?
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 work in winter in Cork?
Yes, solar panels generate electricity all year round. While output is lower in winter, Cork still receives usable daylight hours even in December. Annual generation figures (3,628 kWh for a 4kWp system) already account for seasonal variation.
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 Summerhill South?
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.
