The initial cost of installing solar panels in Ireland can vary widely based on factors such as the size of your home, the number of solar panels required, and the type of panels selected. For a typical 3-bedroom house, the cost can range from �6,000 to �12,000. This figure may increase if you decide to include an energy storage system such as a battery or choose premium quality panels like monocrystalline. A significant portion of this cost can be offset by government grants, with the SEAI offering up to �2,400 towards the installation of photovoltaic systems. Understanding the various elements that contribute to the cost, such as inverter technology, battery storage, and solar panel type, is key to managing your investment.
