IRELAND’S solar pv cost ireland industry is booming and the technology has come down significantly. Despite the upfront costs still being high they are coming down year-on-year as more people see the benefit of creating their own electricity in a green way. This will help Ireland become more independent and reduce its dependence on fossil fuels. A standard four to six-panel system costs around EUR4,500 including inverter, controls, and meters. A battery would add around EUR2,400 to that. If you apply for a grant (which is worth up to EUR2,400) this will cut the initial cost by thousands of euros and make it more affordable for Irish homeowners. The Changing Landscape of Solar PV Cost in Ireland: Trends and Factors With the right conditions, a solar panel system will produce around 5kW per hour, which is enough to power a typical home. That means a household could save up to €100 per month on energy costs. The system will also produce about €1,000 a year in export payments from the electricity supplier for any excess energy it sends back to the grid, which is known as the Clean Energy Guarantee tariff or CEG. O’Mahony calculates that an average homeowner can knock a third off their annual bill by installing the standard four to six panels on their roof. Less than two years ago he was quoting payback periods of 12 years, but with electricity prices up to 30 cents a unit, his figures have moved back to 10 years for most families.
