What Dublin 2 homeowners ask about solar
How much do solar panels cost in Dublin 2?
A 4.4 kWp system in Dublin 2 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 3,660 kWh/year, paying for itself in 4-6 years.
What size solar system do I need for my home in Dublin 2?
Most homes in Dublin 2 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 to clean my solar panels?
In most cases, rain keeps solar panels clean enough in Ireland. If your panels are near trees or at a low angle, an annual clean may improve output by 2-5%. Never use abrasive materials. A soft brush and water is sufficient.
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.
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.
Can I sell excess solar electricity?
Yes. Under Ireland's Microgeneration Support Scheme, you sell surplus electricity at 15-25c/kWh. You need a smart meter (ESB Networks installs free). The first €400/year of export income is tax-free.
How much electricity will solar panels generate in Dublin 2?
Based on Dublin county data, a 4kWp system in Dublin 2 generates approximately 3,660 kWh per year, covering 87% of average household use (4,200 kWh/year). Dublin receives around 1,500 sunshine hours annually.
Can you go off-grid with solar in Dublin 2?
Fully off-grid setups are rare in Dublin 2. 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.
