Common Questions About Going Solar in Tullamore
How much do solar panels cost in Tullamore?
A 4kWp system in Tullamore 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.
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.
What is the payback period for solar panels in Tullamore?
With a net cost of €3,200-€6,200 after the SEAI grant and savings of €932+ per year plus export income, a typical solar system in Tullamore pays for itself in 4-6 years. After payback, you get 20+ years of near-free electricity.
What maintenance do solar panels need?
Solar panels need very little maintenance. Rain keeps them clean in most cases. There are no moving parts. Your inverter may need replacing once in 25 years (10-15 year lifespan). Annual visual checks and occasional cleaning if near trees is all that's 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.
How does shading affect solar panels in Tullamore?
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.
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.
