Common Questions About Going Solar in Santry
How much do solar panels cost in Santry?
A 4kWp system in Santry 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 3,660 kWh/year, paying for itself in 4-6 years.
Is my roof suitable for solar panels in Santry?
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 I get solar panels on an east or west facing roof in Santry?
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.
How long do solar panels last?
Modern solar panels are warrantied for 25-30 years and typically last even longer. Panel efficiency degrades by about 0.5% per year, so after 25 years, your panels will still produce around 87% of their original output. Inverters typically last 10-15 years and may need one replacement.
What is the difference between solar PV and solar thermal?
Solar PV panels generate electricity from sunlight. Solar thermal panels heat water directly. For most Irish homes, solar PV is the better investment: it's more versatile, qualifies for the SEAI grant, and you can sell excess electricity. Solar thermal only heats water.
What is the payback period for solar panels in Santry?
With a net cost of €3,200-€6,200 after the SEAI grant and savings of €948+ per year plus export income, a typical solar system in Santry pays for itself in 4-6 years. After payback, you get 20+ years of near-free electricity.
Do solar panels work in winter in Dublin?
Yes, solar panels generate electricity all year round. While output is lower in winter, Dublin still receives usable daylight hours even in December. Annual generation figures (3,660 kWh for a 4kWp system) already account for seasonal variation.
