What Stonetown homeowners ask about solar
How much do solar panels cost in Stonetown?
A 4kWp system in Stonetown 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 3,524 kWh/year, paying for itself in 4-6 years.
How does shading affect solar panels in Stonetown?
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 solar panels work in winter in Louth?
Yes, solar panels generate electricity all year round. While output is lower in winter, Louth still receives usable daylight hours even in December. Annual generation figures (3,524 kWh for a 4kWp system) already account for seasonal variation.
How long does solar panel installation take?
A typical residential installation takes 1-2 days. This includes scaffolding, mounting the panels, wiring, inverter installation, and connecting to the grid. Your installer handles the ESB Networks notification (NC6 form).
What happens to my solar panels if I move house in Stonetown?
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 Stonetown?
With a net cost of €3,200-€6,200 after the SEAI grant and savings of €935+ per year plus export income, a typical solar system in Stonetown pays for itself in 4-6 years. After payback, you get 20+ years of near-free electricity.
Can I get solar panels on an east or west facing roof in Stonetown?
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.
