Your solar questions for Moylough
How much do solar panels cost in Moylough?
A 4kWp system in Moylough 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 3,544 kWh/year, paying for itself in 4-6 years.
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 size solar system do I need for my home in Moylough?
Most homes in Moylough benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 73% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
Are solar panels worth it in Moylough?
Yes. With estimated savings of €919+ per year, the €1,800 SEAI grant, 0% VAT, and export income of 15-25c/kWh, a solar system in Moylough pays for itself in 4-6 years and lasts 25+ years.
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.
Do solar panels work in winter in Galway?
Yes, solar panels generate electricity all year round. While output is lower in winter, Galway still receives usable daylight hours even in December. Annual generation figures (3,544 kWh for a 4kWp system) already account for seasonal variation.
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.
