Can you install solar panels on a roof in Ireland?

In Ireland, you’ve probably seen a house or two that run on PV solar panels. That’s because the roof is the best place to install your solar panels. The electricity generation varies based on the orientation of your roof and the consequent solar panel inclination. PV solar panels can be integrated into most Irish roofs, from pitched to flat.

Is rooftop solar a viable energy source in Ireland?

The rooftop solar resource within the EU is "vast and underutilised" according to the European Commission (EU Solar Energy Strategy, 2022). In Ireland, the technical potential of residential rooftop solar PV has been estimated at ≈13 GWp (Bódis et al. 2019, Joshi & Deane 2022), compared to the current peak power system demand of ≈5-6 GW.

Where should solar panels be installed in Ireland?

Ideally, a solar power system can be placed in various locations across the roof and ground area of your house. But practically speaking, there are rules to follow regarding installing solar panels in Ireland. As earlier stated, you don’t want to mount your solar panels too far from your house.

Why do Irish homes need solar panels?

Incentives like the Sustainable Energy Authority of Ireland (SEAI)’s grants for solar photovoltaic (PV) systems for homes have also played a pivotal role. Additionally, technological advancements have made solar panels more efficient and cost-effective, further appealing to Irish homeowners looking to reduce their carbon footprint and energy bills.

How well do solar panels work in Ireland?

The direction your roof faces is a major factor in how well solar panels will work. In Ireland, south-facing roofs are the best, as they get the most sunlight during the day. East and west-facing roofs are also options but produce less energy. Here's a general breakdown of efficiency based on roof orientation:

Are monocrystalline solar panels a good choice for Irish homes?

Monocrystalline solar panels, with an efficiency range of 15-22%, are the most common choice for Irish homes. These panels are a great fit for properties with limited roof space or less-than-ideal roof orientations, as identified during your site assessment. They also perform reliably in cloudy weather conditions.
