Frequently Asked Questions About Solar Panels in Roscam
How much do solar panels cost in Roscam?
A 4.4 kWp system in Roscam 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 3,544 kWh/year, paying for itself in 4-6 years.
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.
How does shading affect solar panels in Roscam?
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.
Are solar panels worth it in Roscam?
Yes. With estimated savings of €1063+ per year, the €1,800 SEAI grant, 0% VAT, and export income of 15-25c/kWh, a solar system in Roscam pays for itself in 4-6 years and lasts 25+ years.
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.
Do I need a smart meter for solar panels?
You need a smart meter to sell surplus electricity back to the grid. ESB Networks installs smart meters for free. Your installer submits the NC6 form to ESB Networks after installation, which triggers the meter upgrade if needed.
What happens during a power cut?
Standard grid-tied solar systems shut down during a power cut for safety reasons (to protect ESB workers). If you need backup power, you can install a hybrid inverter with battery storage that provides power during outages.
Can you go off-grid with solar in Roscam?
Fully off-grid setups are rare in Roscam. 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.
